Assignment Operators in C

In C language, the assignment operator stores a certain value in an already declared variable. A variable in C can be assigned the value in the form of a literal, another variable, or an expression.

The value to be assigned forms the right-hand operand, whereas the variable to be assigned should be the operand to the left of the " = " symbol, which is defined as a simple assignment operator in C.

In addition, C has several augmented assignment operators.

The following table lists the assignment operators supported by the C language −

Simple Assignment Operator (=)

The = operator is one of the most frequently used operators in C. As per the ANSI C standard, all the variables must be declared in the beginning. Variable declaration after the first processing statement is not allowed.

You can declare a variable to be assigned a value later in the code, or you can initialize it at the time of declaration.

You can use a literal, another variable, or an expression in the assignment statement.

Once a variable of a certain type is declared, it cannot be assigned a value of any other type. In such a case the C compiler reports a type mismatch error.

In C, the expressions that refer to a memory location are called "lvalue" expressions. A lvalue may appear as either the left-hand or right-hand side of an assignment.

On the other hand, the term rvalue refers to a data value that is stored at some address in memory. A rvalue is an expression that cannot have a value assigned to it which means an rvalue may appear on the right-hand side but not on the left-hand side of an assignment.

Variables are lvalues and so they may appear on the left-hand side of an assignment. Numeric literals are rvalues and so they may not be assigned and cannot appear on the left-hand side. Take a look at the following valid and invalid statements −

Augmented Assignment Operators

In addition to the = operator, C allows you to combine arithmetic and bitwise operators with the = symbol to form augmented or compound assignment operator. The augmented operators offer a convenient shortcut for combining arithmetic or bitwise operation with assignment.

For example, the expression "a += b" has the same effect of performing "a + b" first and then assigning the result back to the variable "a".

Run the code and check its output −

Similarly, the expression "a <<= b" has the same effect of performing "a << b" first and then assigning the result back to the variable "a".

Here is a C program that demonstrates the use of assignment operators in C −

When you compile and execute the above program, it will produce the following result −

An assignment operation assigns the value of the right-hand operand to the storage location named by the left-hand operand. Therefore, the left-hand operand of an assignment operation must be a modifiable l-value. After the assignment, an assignment expression has the value of the left operand but isn't an l-value.

assignment-expression : conditional-expression unary-expression assignment-operator assignment-expression

assignment-operator : one of = *= /= %= += -= <<= >>= &= ^= |=

The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators:

In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place. The left operand must not be an array, a function, or a constant. The specific conversion path, which depends on the two types, is outlined in detail in Type Conversions .

An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition.

C has a wide range of operators to perform various operations.

C Arithmetic Operators

An arithmetic operator performs mathematical operations such as addition, subtraction, multiplication, division etc on numerical values (constants and variables).

Example 1: Arithmetic Operators

The operators + , - and * computes addition, subtraction, and multiplication respectively as you might have expected.

In normal calculation, 9/4 = 2.25 . However, the output is 2 in the program.

It is because both the variables a and b are integers. Hence, the output is also an integer. The compiler neglects the term after the decimal point and shows answer 2 instead of 2.25 .

The modulo operator % computes the remainder. When a=9 is divided by b=4 , the remainder is 1 . The % operator can only be used with integers.

Suppose a = 5.0 , b = 2.0 , c = 5 and d = 2 . Then in C programming,

C Increment and Decrement Operators

C programming has two operators increment ++ and decrement -- to change the value of an operand (constant or variable) by 1.

Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand.

Example 2: Increment and Decrement Operators

Here, the operators ++ and -- are used as prefixes. These two operators can also be used as postfixes like a++ and a-- . Visit this page to learn more about how increment and decrement operators work when used as postfix .

C Assignment Operators

An assignment operator is used for assigning a value to a variable. The most common assignment operator is =

Example 3: Assignment Operators

C relational operators.

A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0.

Relational operators are used in decision making and loops .

Example 4: Relational Operators

C logical operators.

An expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming .

Example 5: Logical Operators

Explanation of logical operator program

(a == b) && (c > 5) evaluates to 1 because both operands (a == b) and (c > b) is 1 (true).
(a == b) && (c < b) evaluates to 0 because operand (c < b) is 0 (false).
(a == b) || (c < b) evaluates to 1 because (a = b) is 1 (true).
(a != b) || (c < b) evaluates to 0 because both operand (a != b) and (c < b) are 0 (false).
!(a != b) evaluates to 1 because operand (a != b) is 0 (false). Hence, !(a != b) is 1 (true).
!(a == b) evaluates to 0 because (a == b) is 1 (true). Hence, !(a == b) is 0 (false).

During computation, mathematical operations like: addition, subtraction, multiplication, division, etc are converted to bit-level which makes processing faster and saves power.

Bitwise operators are used in C programming to perform bit-level operations.

Visit bitwise operator in C to learn more.

Other Operators

Comma operator.

Comma operators are used to link related expressions together. For example:

The sizeof operator

The sizeof is a unary operator that returns the size of data (constants, variables, array, structure, etc).

Example 6: sizeof Operator

Other operators such as ternary operator ?: , reference operator & , dereference operator * and member selection operator -> will be discussed in later tutorials.

C Assignment Operators

Summary : in this tutorial, you’ll learn about the C assignment operators and how to use them effectively.

Introduction to the C assignment operators

An assignment operator assigns the vale of the right-hand operand to the left-hand operand. The following example uses the assignment operator (=) to assign 1 to the counter variable:

After the assignmment, the counter variable holds the number 1.

The following example adds 1 to the counter and assign the result to the counter:

The = assignment operator is called a simple assignment operator. It assigns the value of the left operand to the right operand.

Besides the simple assignment operator, C supports compound assignment operators. A compound assignment operator performs the operation specified by the additional operator and then assigns the result to the left operand.

The following example uses a compound-assignment operator (+=):

The expression:

is equivalent to the following expression:

The following table illustrates the compound-assignment operators in C:

A simple assignment operator assigns the value of the left operand to the right operand.
A compound assignment operator performs the operation specified by the additional operator and then assigns the result to the left operand.

Assignment Operator in C

Last updated on July 27, 2020

We have already used the assignment operator ( = ) several times before. Let's discuss it here in detail. The assignment operator ( = ) is used to assign a value to the variable. Its general format is as follows:

The operand on the left side of the assignment operator must be a variable and operand on the right-hand side must be a constant, variable or expression. Here are some examples:

The precedence of the assignment operator is lower than all the operators we have discussed so far and it associates from right to left.

We can also assign the same value to multiple variables at once.

here x , y and z are initialized to 100 .

Since the associativity of the assignment operator ( = ) is from right to left. The above expression is equivalent to the following:

Note that expressions like:

are called assignment expression. If we put a semicolon( ; ) at the end of the expression like this:

then the assignment expression becomes assignment statement.

Compound Assignment Operator #

Assignment operations that use the old value of a variable to compute its new value are called Compound Assignment.

Consider the following two statements:

Here the second statement adds 5 to the existing value of x . This value is then assigned back to x . Now, the new value of x is 105 .

To handle such operations more succinctly, C provides a special operator called Compound Assignment operator.

The general format of compound assignment operator is as follows:

where op can be any of the arithmetic operators ( + , - , * , / , % ). The above statement is functionally equivalent to the following:

Note : In addition to arithmetic operators, op can also be >> (right shift), << (left shift), | (Bitwise OR), & (Bitwise AND), ^ (Bitwise XOR). We haven't discussed these operators yet.

After evaluating the expression, the op operator is then applied to the result of the expression and the current value of the variable (on the RHS). The result of this operation is then assigned back to the variable (on the LHS). Let's take some examples: The statement:

is equivalent to x = x + 5; or x = x + (5); .

Similarly, the statement:

is equivalent to x = x * 2; or x = x * (2); .

Since, expression on the right side of op operator is evaluated first, the statement:

is equivalent to x = x * (y + 1) .

The precedence of compound assignment operators are same and they associate from right to left (see the precedence table ).

The following table lists some Compound assignment operators:

The following program demonstrates Compound assignment operators in action:

Assignment Operator

The assignment operator allows us to change the value of a modifiable data object (for beginning programmers this typically means a variable). It is associated with the concept of moving a value into the storage location (again usually a variable). Within C++ programming language the symbol used is the equal symbol. But bite your tongue, when you see the = symbol you need to start thinking: assignment. The assignment operator has two operands. The one to the left of the operator is usually an identifier name for a variable. The one to the right of the operator is a value.

The value 21 is moved to the memory location for the variable named: age. Another way to say it: age is assigned the value 21.

The item to the right of the assignment operator is an expression. The expression will be evaluated and the answer is 14. The value 14 would assigned to the variable named: total_cousins.

The expression to the right of the assignment operator contains some identifier names. The program would fetch the values stored in those variables; add them together and get a value of 44; then assign the 44 to the total_students variable.

As we have seen, assignment operators are used to assigning value to a variable. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value. The value on the right side must be of the same data-type of the variable on the left side otherwise the compiler will raise an error. Different types of assignment operators are shown below:

“=” : This is the simplest assignment operator, which was discussed above. This operator is used to assign the value on the right to the variable on the left. For example: a = 10; b = 20; ch = 'y';

If initially the value 5 is stored in the variable a, then: (a += 6) is equal to 11. (the same as: a = a + 6)

If initially value 8 is stored in the variable a, then (a -= 6) is equal to 2. (the same as a = a - 6)

If initially value 5 is stored in the variable a,, then (a *= 6) is equal to 30. (the same as a = a * 6)

If initially value 6 is stored in the variable a, then (a /= 2) is equal to 3. (the same as a = a / 2)

Below example illustrates the various Assignment Operators:

Assignment and shorthand assignment operator in C

Quick links.

Shorthand assignment

Assignment operator is used to assign value to a variable (memory location). There is a single assignment operator = in C. It evaluates expression on right side of = symbol and assigns evaluated value to left side the variable.

For example consider the below assignment table.

The RHS of assignment operator must be a constant, expression or variable. Whereas LHS must be a variable (valid memory location).

Shorthand assignment operator

C supports a short variant of assignment operator called compound assignment or shorthand assignment. Shorthand assignment operator combines one of the arithmetic or bitwise operators with assignment operator.

For example, consider following C statements.

The above expression a = a + 2 is equivalent to a += 2 .

Similarly, there are many shorthand assignment operators. Below is a list of shorthand assignment operators in C.

Assignment operator in c.

Last Updated on June 23, 2023 by Prepbytes

This type of operator is employed for transforming and assigning values to variables within an operation. In an assignment operation, the right side represents a value, while the left side corresponds to a variable. It is essential that the value on the right side has the same data type as the variable on the left side. If this requirement is not fulfilled, the compiler will issue an error.

What is Assignment Operator in C language?

In C, the assignment operator serves the purpose of assigning a value to a variable. It is denoted by the equals sign (=) and plays a vital role in storing data within variables for further utilization in code. When using the assignment operator, the value present on the right-hand side is assigned to the variable on the left-hand side. This fundamental operation allows developers to store and manipulate data effectively throughout their programs.

Example of Assignment Operator in C

For example, consider the following line of code:

Types of Assignment Operators in C

Here is a list of the assignment operators that you can find in the C language:

Simple assignment operator (=): This is the basic assignment operator, which assigns the value on the right-hand side to the variable on the left-hand side.

Addition assignment operator (+=): This operator adds the value on the right-hand side to the variable on the left-hand side and assigns the result back to the variable.

x += 3; // Equivalent to x = x + 3; (adds 3 to the current value of "x" and assigns the result back to "x")

Subtraction assignment operator (-=): This operator subtracts the value on the right-hand side from the variable on the left-hand side and assigns the result back to the variable.

x -= 4; // Equivalent to x = x – 4; (subtracts 4 from the current value of "x" and assigns the result back to "x")

* Multiplication assignment operator ( =):** This operator multiplies the value on the right-hand side with the variable on the left-hand side and assigns the result back to the variable.

x = 2; // Equivalent to x = x 2; (multiplies the current value of "x" by 2 and assigns the result back to "x")

Division assignment operator (/=): This operator divides the variable on the left-hand side by the value on the right-hand side and assigns the result back to the variable.

x /= 2; // Equivalent to x = x / 2; (divides the current value of "x" by 2 and assigns the result back to "x")

Bitwise AND assignment (&=): The bitwise AND assignment operator "&=" performs a bitwise AND operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.

x &= 3; // Binary: 0011 // After bitwise AND assignment: x = 1 (Binary: 0001)

Bitwise OR assignment (|=): The bitwise OR assignment operator "|=" performs a bitwise OR operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.

x |= 3; // Binary: 0011 // After bitwise OR assignment: x = 7 (Binary: 0111)

Bitwise XOR assignment (^=): The bitwise XOR assignment operator "^=" performs a bitwise XOR operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.

x ^= 3; // Binary: 0011 // After bitwise XOR assignment: x = 6 (Binary: 0110)

Left shift assignment (<<=): The left shift assignment operator "<<=" shifts the bits of the value on the left-hand side to the left by the number of positions specified by the value on the right-hand side. It then assigns the result back to the left-hand side variable.

x <<= 2; // Binary: 010100 (Shifted left by 2 positions) // After left shift assignment: x = 20 (Binary: 10100)

Right shift assignment (>>=): The right shift assignment operator ">>=" shifts the bits of the value on the left-hand side to the right by the number of positions specified by the value on the right-hand side. It then assigns the result back to the left-hand side variable.

x >>= 2; // Binary: 101 (Shifted right by 2 positions) // After right shift assignment: x = 5 (Binary: 101)

Conclusion The assignment operator in C, denoted by the equals sign (=), is used to assign a value to a variable. It is a fundamental operation that allows programmers to store data in variables for further use in their code. In addition to the simple assignment operator, C provides compound assignment operators that combine arithmetic or bitwise operations with assignment, allowing for concise and efficient code.

FAQs related to Assignment Operator in C

Q1. Can I assign a value of one data type to a variable of another data type? In most cases, assigning a value of one data type to a variable of another data type will result in a warning or error from the compiler. It is generally recommended to assign values of compatible data types to variables.

Q2. What is the difference between the assignment operator (=) and the comparison operator (==)? The assignment operator (=) is used to assign a value to a variable, while the comparison operator (==) is used to check if two values are equal. It is important not to confuse these two operators.

Q3. Can I use multiple assignment operators in a single statement? No, it is not possible to use multiple assignment operators in a single statement. Each assignment operator should be used separately for assigning values to different variables.

Q4. Are there any limitations on the right-hand side value of the assignment operator? The right-hand side value of the assignment operator should be compatible with the data type of the left-hand side variable. If the data types are not compatible, it may lead to unexpected behavior or compiler errors.

Q5. Can I assign the result of an expression to a variable using the assignment operator? Yes, it is possible to assign the result of an expression to a variable using the assignment operator. For example, x = y + z; assigns the sum of y and z to the variable x.

Q6. What happens if I assign a value to an uninitialized variable? Assigning a value to an uninitialized variable will initialize it with the assigned value. However, it is considered good practice to explicitly initialize variables before using them to avoid potential bugs or unintended behavior.

Practice Problems on Assignment Operators in C

1. what will be the value of a after the following code is executed.

A) 10 B) 11 C) 12 D) 15

Answer – C. 12 Explanation: a starts at 10, increases by 5 to 15, then decreases by 3 to 12. So, a is 12.

2. After executing the following code, what is the value of num ?

A) 4 B) 8 C) 16 D) 32

Answer: C) 16 Explanation: After right-shifting 8 (binary 1000) by one and then left-shifting the result by two, the value becomes 16 (binary 10000).

Q. How does the /= operator function? Is it a combination of two other operators?

A. The /= operator is a compound assignment operator in C++. It divides the left operand by the right operand and assigns the result to the left operand. It is equivalent to using the / operator and then the = operator separately.

Q. What is the most basic operator among all the assignment operators available in the C language?

A. The most basic assignment operator in the C language is the simple = operator, which is used for assigning a value to a variable.

Assignment operators are used to assign the result of an expression to a variable.
There are two types of assignment operators in C. Simple assignment operator and compound assignment operator.
Compound Assignment operators are easy to use and the left operand of expression needs not to write again and again.
They work the same way in C++ as in C.

In the example below, we use the + operator to add together two values:

Although the + operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable:

C divides the operators into the following groups:

Arithmetic operators
Assignment operators
Comparison operators
Logical operators
Bitwise operators

Arithmetic Operators

Arithmetic operators are used to perform common mathematical operations.

Assignment Operators

Assignment operators are used to assign values to variables.

In the example below, we use the assignment operator ( = ) to assign the value 10 to a variable called x :

The addition assignment operator ( += ) adds a value to a variable:

A list of all assignment operators:

Comparison Operators

Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.

The return value of a comparison is either 1 or 0 , which means true ( 1 ) or false ( 0 ). These values are known as Boolean values , and you will learn more about them in the Booleans and If..Else chapter.

Comparison operators are used to compare two values.

Note: The return value of a comparison is either true ( 1 ) or false ( 0 ).

In the following example, we use the greater than operator ( > ) to find out if 5 is greater than 3:

A list of all comparison operators:

Logical Operators

You can also test for true or false values with logical operators.

Logical operators are used to determine the logic between variables or values:

Welcome, bold programmers and coding enthusiasts! Let's set the stage: you're at your desk, fingers hovering over the keyboard, ready to embark on a journey deep into the belly of C programming. You might be wondering, why do I need to know about these 'assignment operators'?

Well, imagine trying to build a house with a toolbox that only has a hammer. You could probably make something that vaguely resembles a house, but without a screwdriver, wrench, or saw, it's going to be a bit...wobbly. This, my friends, is the importance of understanding operators in C. They're like the indispensable tools in your coding toolbox. And today, we're honing in on the assignment operators .

Now, our mission, should we choose to accept it, is to delve into the world of assignment operators in C. Like secret agents discovering the inner workings of a villain's lair, we're going to uncover the secrets that these '=' or '+=' symbols hold.

To all the night owls out there, I see you, and I raise you an operator. Just like how a cup of coffee (or three) helps us conquer that midnight oil, mastering operators in C can transform your coding journey from a groggy stumble to a smooth sprint.

But don't just take my word for it. Let's take a real-world example. Imagine you're coding a video game. You need your character to jump higher each time they collect a power-up. Without assignment operators, you'd be stuck adding numbers line by line. But with the '+=' operator, you can simply write 'jumpHeight += powerUpBoost,' and your code becomes a thing of elegance. It's like going from riding a tricycle to a high-speed motorbike.

In this article, we're going to unpack, examine, and get intimately acquainted with these assignment operators. We'll reveal their secrets, understand their behaviors, and learn how to use them effectively to power our C programming skills to new heights. Let's strap in, buckle up, and get ready for takeoff into the cosmic realms of C assignment operators!

The Basics Of C Operators

Deep dive into assignment operators in c, detailed exploration of each assignment operator, common use cases of assignment operators, common mistakes and how to avoid them, practice exercises, references and further reading.

Alright, get ready to pack your mental suitcase as we prepare to embark on the grand tour of C operators. We'll be stopping by the various categories, getting to know the locals (the operators, that is), and understanding how they contribute to the vibrant community that is a C program.

What Are Operators In C?

Operators in C are like the spicy condiments of coding. Without them, you'd be left with a bland dish—or rather, a simple list of variables. But splash on some operators, and suddenly you've got yourself an extravagant, dynamic, computational feast. In technical terms, operators are special symbols that perform specific operations on one, two, or three operands, and then return a result . They're the magic sauce that allows us to perform calculations, manipulate bits, and compare data.

Categories Of Operators In C

Now, just as you wouldn't use hot sauce on your ice cream (unless that's your thing), different operators serve different purposes. C language has been generous enough to provide us with a variety of operator categories, each with its distinct charm and role.

Let's break it down:

Imagine you're running a pizza shop. The arithmetic operators are like your basic ingredients: cheese, sauce, dough. They form the foundation of your pizza (program). But then you want to offer different pizza sizes. That's where your relational operators come in, comparing the diameter of small, medium, and large pizzas.

You're going well, but then you decide to offer deals. Buy two pizzas, get one free. Enter the logical operators , evaluating whether the conditions for the deal have been met. And finally, you want to spice things up with some exotic ingredients. That's your bitwise operators , working behind the scenes, adding that unique flavor that makes your customers keep coming back.

However, today, we're going to focus on a particular subset of the arithmetic operators: the assignment operators . These are the operators that don't just make the pizza but ensure it reaches the customer's plate (or in this case, the right variable).

Next up: We explore these unsung heroes of the programming world, toasting their accomplishments and discovering their capabilities. So, hold onto your hats and glasses, folks. This here's the wildest ride in the coding wilderness!

Prepare your diving gear and adjust your oxygen masks, friends, as we're about to plunge deep into the ocean of C programming. Hidden in the coral reef of code, you'll find the bright and beautiful creatures known as assignment operators.

What Are Assignment Operators?

In the broad ocean of C operators, the assignment operators are the dolphins - intelligent, adaptable, and extremely useful. On the surface, they may appear simple, but don't be fooled; these creatures are powerful. They have the capability to not only assign values to variables but also perform arithmetic operations concurrently.

The basic assignment operator in C is the '=' symbol. It's like the water of the ocean, essential to life (in the world of C programming). But alongside this staple, we have a whole family of compound assignment operators including '+=', '-=', '*=', '/=', and '%='. These are the playful dolphins leaping out of the water, each adding their unique twist to the task of assignment.

Syntax And Usage Of Assignment Operators

Remember, even dolphins have their ways of communicating, and so do assignment operators. They communicate through their syntax. The syntax for assignment operators in C follows a simple pattern:

In this dance, the operator and the '=' symbol perform a duet, holding onto each other without a space in between. They're the dancing pair that adds life to the party (aka your program).

Let's say you've won the lottery (congratulations, by the way!) and you want to divide your winnings between your three children. You could write out the arithmetic long-hand, or you could use the '/=' operator to streamline your process:

Just like that, your winnings are divided evenly, no calculator required.

List Of Assignment Operators In C

As promised, let's get to know the whole family of assignment operators residing in the C ocean:

Alright, we've taken the plunge and gotten our feet wet (or fins, in the case of our dolphin friends). But the dive is far from over. Next up, we're going to swim alongside each of these assignment operators, exploring their unique behaviors and abilities in the wild, vibrant world of C programming. So, keep your scuba gear on and get ready for more underwater adventure!

Welcome back, dear diver! Now that we've acquainted ourselves with the beautiful pod of dolphins, aka assignment operators, it's time to learn about each dolphin individually. We're about to uncover their quirks, appreciate their styles, and recognize their talents.

The Simple Assignment Operator '='

Let's start with the leader of the pack: the '=' operator. This unassuming symbol is like the diligent mail carrier, ensuring the right packages (values) get to the correct houses (variables).

Take a look at this:

In this code snippet, '=' ensures that the value '5' gets assigned to the variable 'chocolate'. Simple as that. No muss, no fuss, just a straightforward delivery of value.

The Addition Assignment Operator '+='

Next, we have the '+=' operator. This operator is a bit like a friendly baker. He takes what he has, adds more ingredients, and gives you the result - a delicious cake! Or, in this case, a new value.

Consider this:

We started with 12 doughnuts. But oh look, a friend dropped by with 3 more! So we add those to our box, and now we have 15. The '+=' operator made that addition quick and easy.

The Subtraction Assignment Operator '-='

Following the '+=' operator, we have its twin but with a different personality - the '-=' operator. If '+=' is the friendly baker, then '-=' is the weight-conscious friend who always removes extra toppings from their pizza. They take away rather than add.

For instance:

You've consumed 2000 calories today, but then you went for a run and burned 500. The '-=' operator is there to quickly update your calorie count.

The Multiplication Assignment Operator '*='

Say hello to the '*=' operator. This one is like the enthusiastic party planner who multiplies the fun! They take your initial value and multiply it with another, bringing more to the table.

Check this out:

You're at a level 7 excitement about your upcoming birthday, but then you learn that your best friend is flying in to celebrate with you. Your excitement level just doubled, and '*=' is here to make that calculation easy.

The Division Assignment Operator '/='

Here's the '/=' operator, the calm and composed yoga teacher of the group. They're all about division and balance. They take your original value and divide it by another, bringing harmony to your code.

You're pretty anxious about your job interview - let's say a level 10 anxiety. But then you do some deep breathing exercises, which helps you halve your anxiety level. The '/=' operator helps you reflect that change in your code.

The Modulus Assignment Operator '%='

Finally, we meet the quirky '%=' operator, the mystery novelist of the group. They're not about the whole story but the remainder, the leftovers, the little details others might overlook.

Look at this:

You have 10 books to distribute equally among your 3 friends. Everyone gets 3, and you're left with 1 book. The '%=' operator is there to quickly calculate that remainder for you.

That's the end of our detailed exploration. I hope this underwater journey has provided you with a greater appreciation and understanding of these remarkable creatures. Remember, each operator, like a dolphin, has its unique abilities, and knowing how to utilize them effectively can greatly enhance your programming prowess.

Now, let's swerve away from the theoretical and deep-dive into the practical. After all, C assignment operators aren't just sparkling little seashells you collect and admire. They're more like versatile tools in your programming Swiss Army knife. So, let's carve out some real-world use cases for our cherished assignment operators.

Variable Initialization And Value Change

Assignment operators aren't just for show; they've got some moves. Take our plain and humble '='. It's the bread-and-butter operator used in variable initialization and value changes, helping your code be as versatile as a chameleon.

In this scenario, our friend '=' is doing double duty—initializing 'a' with the value 10 and then changing it to 20. Not flashy, but oh-so-vital.

Calculation Updates In Real-Time Applications

Assignment operators are like those awesome, multitasking waitstaff you see in busy restaurants, juggling multiple tables and orders while still managing to serve everyone with a smile. They are brilliant when you want to perform real-time updates to your data.

In this scenario, '+=' and '-=' are the maitre d' of our code-restaurant, updating the user's balance with each buy or sell order.

Running Totals And Averages

Assignment operators are great runners - they don't tire and always keep the tally running.

Here, the '+=' and '-=' operators keep a running tally of points, allowing the system to adjust to the ebbs and flows of the school year like a seasoned marathon runner pacing themselves.

Iterations In Loop Constructs

The '*=' and '/=' operators often lurk within loop constructs, handling iterations with the grace of a prima ballerina. They're the choreographers of your loops, making sure each iteration flows seamlessly into the next.

In this case, '/=' is the elegant dancer gracefully halving 'i' with each twirl across the dance floor (iteration).

Working With Remainders

And let's not forget our mysterious '%=', the detective of the bunch, always searching for the remainder, the evidence left behind.

Here, '%=' is the sleuth, determining whether a number is even or odd by examining the remainder when divided by 2.

So, these are just a few examples of how assignment operators flex their muscles in the real world. They're like superheroes, each with their unique powers, ready to assist you in writing clean, efficient, and understandable code. Use them wisely, and your code will be as smooth as a well-choreographed ballet.

Let's face it, even the best of us trip over our own feet sometimes. And when it comes to assignment operators in C, there are some pitfalls that could make you stumble. But don't worry! We've all been there. Let's shed some light on these common mistakes so we can step over them with the grace of a ballet dancer leaping over a pit of snapping alligators.

Confusing Assignment With Equality

A surprisingly common misstep is confusing the assignment operator '=' with the equality operator '=='. It's like mixing up salt with sugar while baking. Sure, they might look similar, but one will definitely not sweeten your cake.

In this snippet, instead of checking if 'a' equals 10, we've assigned 'a' the value 10. The compiler will happily let this pass and might even give you a standing ovation for your comedy of errors. The correct approach?

Overlooking Operator Precedence

C operators are a bit like the characters in "Game of Thrones." They've got a complex hierarchy and they respect the rule of precedence. Sometimes, this can lead to unexpected results. For instance, check out this bit of misdirection:

Here, '/=' doesn't immediately divide 'a' by 2. It waits for the multiplication to happen (due to operator precedence), and then performs the operation. So it's actually doing a /= (2*5), not (a/=2)*5. It's like arriving late to a party and finding out all the pizza is gone. To ensure you get your slice, use parentheses:

Misusing Modulo With Floats

Ah, the modulo operator, always looking for the remainder. But when you ask it to work with floats, it gets as confused as a penguin in a desert. It simply can't compute.

Modulo and floats go together like oil and water. The solution? Stick to integers when dealing with '%='.

So there you have it. Some common missteps while dancing with assignment operators and the quick moves to avoid them. Just remember, every great coder has tripped before. The key is to keep your chin up, learn from your stumbles, and soon you'll be waltzing with assignment operators like a seasoned pro.

Alright, amigos! It's time to put your newfound knowledge to the test. After all, becoming a master in the art of C assignment operators is not a walk in the park, it's a marathon run on a stony path with occasional dance-offs. So brace yourselves and let's get those brain cells pumping.

Exercise 1: The Shy Variable

Your task here is to write a C program that initializes an integer variable to 10. Then, using only assignment operators, make that variable as shy as a teenager at their first dance. I mean, reduce it to zero without directly assigning it to zero. You might want to remember the '/=' operator here. He's like the high school wallflower who can suddenly breakdance like a champ when the music starts playing.

Exercise 2: Sneaky Increment

The '+=' operator is like the mischievous friend who always pushes you into the spotlight when you least expect it. Create a program that initializes an integer to 0. Then, using a loop and our sneaky '+=' friend, increment that variable until it's equal to 100. Here's the catch: You can't use '+=' with anything greater than 1. It's a slow and steady race to the finish line!

Exercise 3: Modulo Madness

Remember the modulo operator? It's like the friend who always knows how much pizza is left over after a party. Create a program that counts from 1 to 100. But here's the twist: for every number that's divisible by 3, print "Fizz", and for every number divisible by 5, print "Buzz". If a number is divisible by both 3 and 5, print "FizzBuzz". For all other numbers, just print the number. This will help you get better acquainted with our friend '%='.

Exercise 4: Swapping Values

Create a program that swaps the values of two variables without using a third temporary variable. Remember, your only allies here are the assignment operators. This is like trying to switch places on the dance floor without stepping on anyone's toes.

Exercise 5: Converting Fahrenheit To Celsius

Let's play with the ' =' operator. Write a program that converts a temperature in Fahrenheit to Celsius. The formula to convert Fahrenheit to Celsius is (Fahrenheit - 32) * 5 / 9 . As a challenge, try doing the conversion in a single line using the '-=', ' =' and '/=' operators. It's like preparing a complicated dinner recipe using only a few simple steps.

Remember, practice makes perfect, especially when it comes to mastering C assignment operators. Don't be disheartened if you stumble, just dust yourself off and try again. Because as the saying goes, "The master has failed more times than the beginner has even tried". So, good luck, and happy coding!

C - Bitwise OR and assignment operator

The Bitwise OR and assignment operator (|=) assigns the first operand a value equal to the result of Bitwise OR operation of two operands.

(x |= y) is equivalent to (x = x | y)

The Bitwise OR operator (|) is a binary operator which takes two bit patterns of equal length and performs the logical OR operation on each pair of corresponding bits. It returns 1 if either or both bits at the same position are 1, else returns 0.

The example below describes how bitwise OR operator works:

The code of using Bitwise OR operator (|) is given below:

The output of the above code will be:

Example: Find largest power of 2 less than or equal to given number

Consider an integer 1000. In the bit-wise format, it can be written as 1111101000. However, all bits are not written here. A complete representation will be 32 bit representation as given below:

Performing N |= (N>>i) operation, where i = 1, 2, 4, 8, 16 will change all right side bit to 1. When applied on 1000, the result in 32 bit representation is given below:

Adding one to this result and then right shifting the result by one place will give largest power of 2 less than or equal to 1000.

The below code will calculate the largest power of 2 less than or equal to given number.

The above code will give the following output:

C operator precedence.

The following table lists the precedence and associativity of C operators. Operators are listed top to bottom, in descending precedence.

↑ The operand of prefix ++ and -- can't be a type cast. This rule grammatically forbids some expressions that would be semantically invalid anyway. Some compilers ignore this rule and detect the invalidity semantically.
↑ The operand of sizeof can't be a type cast: the expression sizeof ( int ) * p is unambiguously interpreted as ( sizeof ( int ) ) * p , but not sizeof ( ( int ) * p ) .
↑ The expression in the middle of the conditional operator (between ? and : ) is parsed as if parenthesized: its precedence relative to ?: is ignored.
↑ Assignment operators' left operands must be unary (level-2 non-cast) expressions. This rule grammatically forbids some expressions that would be semantically invalid anyway. Many compilers ignore this rule and detect the invalidity semantically. For example, e = a < d ? a ++ : a = d is an expression that cannot be parsed because of this rule. However, many compilers ignore this rule and parse it as e = ( ( ( a < d ) ? ( a ++ ) : a ) = d ) , and then give an error because it is semantically invalid.

When parsing an expression, an operator which is listed on some row will be bound tighter (as if by parentheses) to its arguments than any operator that is listed on a row further below it. For example, the expression * p ++ is parsed as * ( p ++ ) , and not as ( * p ) ++ .

Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. For example, the expression a = b = c is parsed as a = ( b = c ) , and not as ( a = b ) = c because of right-to-left associativity.

[ edit ] Notes

Precedence and associativity are independent from order of evaluation .

The standard itself doesn't specify precedence levels. They are derived from the grammar.

In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't have the restrictions about their operands.

Associativity specification is redundant for unary operators and is only shown for completeness: unary prefix operators always associate right-to-left ( sizeof ++* p is sizeof ( ++ ( * p ) ) ) and unary postfix operators always associate left-to-right ( a [ 1 ] [ 2 ] ++ is ( ( a [ 1 ] ) [ 2 ] ) ++ ). Note that the associativity is meaningful for member access operators, even though they are grouped with unary postfix operators: a. b ++ is parsed ( a. b ) ++ and not a. ( b ++ ) .

Kotlin Conditional Assignment: Crafting Smarter Code Decisions

Dhaval Tarsariya

Frequently asked questions

Does kotlin have a ternary operator, how to write if-else in one line in kotlin, what is the alternative to a ternary operator in kotlin, what does the : (elvis operator) do in kotlin, how to check if something is null in kotlin.

Kotlin's approach to conditional assignment is both concise and expressive, allowing developers to write cleaner and more readable code. By using Kotlin's powerful syntax, you can easily handle various conditions and assignments in a streamlined manner. Additionally, extension functions play a crucial role in Kotlin conditional assignments, enabling developers to reduce wordiness and improve code organization.

Conditional assignment plays a crucial role in any programming language. It allows developers to assign a value to a variable based on some condition. In Kotlin, conditional assignment is an efficient way to execute logic without the clutter of excessive if-else statements. Kotlin's approach to conditional assignment is not only concise but also enhances the readability and maintainability of code.

Many developers moving from C-like languages may initially miss the familiar ternary operator (? :) used for inline conditional assignment. However, Kotlin provides powerful tools for conditional assignment. In this blog, we will explore how Kotlin handles conditional assignments, focusing on the absence of the traditional ternary operator and the alternatives Kotlin offers.

Understanding Kotlin's own mechanisms — such as the if expression, when expression, and the Elvis operator—can vastly improve code conciseness. Let’s dive into the kotlin syntax and look at how we can effectively assign values conditionally.

Kotlin and the Absence of the Ternary Operator

Many developers are accustomed to the ternary conditional operator from other languages like Java where you might find a simple condition ? trueValue : falseValue syntax. Yet, on delving into Kotlin, one finds that this specific operator is conspicuously absent. Kotlin’s designers intentionally left out the traditional ternary operator to maintain simplicity in the language’s design.

The primary reason for this decision is that the Kotlin if expression already serves the same purpose as the ternary operator but with greater clarity. Additionally, Kotlin's elvis operator (?:) is used to handle nullability and can make code concise for short and shallow conditional expressions. While some developers miss the elegance and aesthetics of the ternary operator, the elvis operator provides a readable and expressive alternative for simple conditions and expressions.

Kotlin focuses on being readable and expressive, and this is where if expressions take center stage. In this language, if isn’t just a statement; it’s an expression with a return value. Let’s explore how you can use if expressions to write clear and concise conditional assignments.

The Power of the If Expression

Kotlin transforms the traditional if else block from a mere control flow statement into an expression that returns a value. This means the result of an if expression can be directly assigned to a variable. The syntax is simple:

Here, val max will hold the greater of the two values a and b. It's a common pattern in Kotlin and replaces the ternary operator found in other languages. You can see that Kotlin prefers the use of clearer and more expressive forms of coding, and that is especially apparent with the use of if expressions.

An if expression in Kotlin is powerful. You can execute blocks of code within each branch, not just single line statements. For example:

The if expression evaluates each block and returns the value of the last expression in the executed block. This conditional expression can become as complex as necessary, still maintaining readability. With if expressions, Kotlin encourages developers to write conditional logic in a way that's expressive and concise.

Efficient Use of Kotlin’s Inline If for Concise Code

Kotlin’s inline if is your go-to for one-liners. This inline conditional expression allows you to assign values based on a condition in just a single line of code. It works fine as both a statement and an expression. Here’s how you can use it:

In one line, you evaluate the condition and assign the val max the value of a if a is greater than b, else you assign it the value of b. This is the Kotlin ternary operator example in practice, even though Kotlin doesn’t use the term “ternary operator.”

Although Kotlin lacks a traditional ternary operation, you can achieve similar functionality using alternatives like takeIf {} with an elvis operator, takeUnless {}, and inline extension methods to express code flexibly.

Inline if statements offer a swift way to handle conditional assignments without the verbosity of a multi-line if else statement. They are perfect when you need to make a quick decision between two possible values. This usage pattern encourages cleaner and more readable code— it’s clear, concise, and does exactly what it looks like on the surface.

Kotlin’s design promotes the maintainability of code, and inline conditional expressions are a testament to this philosophy. Let’s delve into Kotlin’s specific features next, starting with the Elvis operator.

The Elvis Operator: A Kotlin-specific Feature

Speaking of distinctive Kotlin features, the elvis operator takes a special place in Kotlin's conditional assignment arsenal. The elvis operator (?:) comes into play when dealing with nullable types, allowing you to specify a default value to use when a nullable expression resolves to null. Here's how it looks in practice:

In the above example, val name is assigned the value of person.name if it's not null; else "Unknown" is used as a default value. This operator is a succinct way to provide fallback values, and Kotlin's elvis operator is particularly handy to avoid NullPointerException that can occur in Java.

The elvis operator becomes even more powerful when combined with other Kotlin features. For instance, its use with Kotlin's return or throw can simplify functions significantly. Consider this example where it is combined with a throw:

In the example, val processedAge will be the age of the person, but if age is null, an exception is thrown immediately. Conclusively, Kotlin's elvis operator not only offers a straightforward syntax for null checks but encourages writing robust, null-safe code.

Practical Examples of Kotlin Ternary Assignment

Even though Kotlin does not have a traditional ternary operator, the techniques we've discussed serve the same purpose and often result in more readable code. Let's take a look at some practical examples.

Given two numbers, we might want to find out the larger number. Instead of writing a multi-line if else statement, you can simplify it using Kotlin’s inline if:

Something more complex may involve evaluating a grade based on a test score:

Here, val grade will contain the grade corresponding to the score. Kotlin’s if expression makes the code flow easy to follow and reduces it to essentially a one-liner for each condition.

For nullability checks, here’s how you might handle nullable strings:

With the above code, you can assign a default "guest" username if the user input returned null. It's a clean and expressive way to handle nullable values with Kotlin's elvis operator.

These examples illustrate how Kotlin uses if expressions and the elvis operator to handle conditional assignment.

Closing Thoughts

In the Kotlin universe, conditional assignment is elegantly simple yet profoundly potent. As we have seen, Kotlin does away with the traditional ternary operator, choosing clarity over brevity. Kotlin's if expressions and the elvis operator are prime examples of its readable and practical approach to coding.

By embracing Kotlin conditional assignment, developers can write code that not only communicates intent clearly but also manages complexity with sophistication. We've traversed through how val max = if (a > b) a else b and val name = person.name ?: "Unknown" are more than just replacements for ternary conditionals; they denote a language philosophy centered around safety and expressiveness.

In summary, Kotlin's conditional assignment tools offer a powerful means to write clear, maintainable, and concise code. It's a reminder that sometimes the absence of a feature, like a traditional ternary operator, can inspire a more innovative approach that can enhance the way we write and understand code.

Summer 2024 Rural Non-congregate Feeding FAQ's

The California Department of Education (CDE) recognizes that program operators have many questions about the implementation of this new program. The purpose of this announcement is to highlight existing resources for program operators and to address FAQs the CDE has received related to non-congregate feeding options.

The U.S. Department of Agriculture (USDA) has released two separate policy memos that provide additional guidance related to implementing non-congregate feeding in rural areas:

In April 2024, the CDE also issued CDE Management Bulletin SNP-05 2024, SFSP 06-2024 Non-Congregate Meal Service Options in Rural Areas . This management bulletin consolidates existing guidance released by the USDA through the interim final rule and policy memorandum.

Frequently Asked Questions

Expand All | Collapse All

Can sponsors provide both congregate and non-congregate meal services at the same site?

In their guidance, the USDA provides the following examples in which sites can operate as both congregate and non-congregate:

A site that only offers breakfast through a congregate meal service may be approved to provide a lunch through non-congregate meal service. In these instances, meal services must not be concurrent, so, in this example, the non-congregate lunch meal service must be conducted after the congregate breakfast meal service has concluded.
A site that serves lunch and breakfast three days a week may be approved to provide non-congregate meals for days with no congregate service, including weekends. Program operators must have a written program integrity plan and processes in place that ensure children are not receiving more meals than are allowable under federal regulations and that duplicate meals are not served.

We are a school food authority (SFA) providing congregate breakfast and congregate lunch services to our summer school students. Can we also provide multiple days’ worth of non-congregate meals to families after our daily summer school lunch service?

No. In this example, the SFA would not be allowed to provide multiple days’ worth of meals after summer school lunch service because congregate meal service already exists at this feeding site. SFAs that are interested in providing multiple days’ worth of meals must identify rural sites in which no congregate meal service is available.

Can a summer meal site utilize multiple non-congregate meal options?

Yes. Program operators are encouraged to identify the non-congregate meal options that best fit the needs of their community. For example, a program operator may choose to provide multiple days’ worth of meals to families and allow for parent/guardians of eligible children to pick up meals.

How many days’ worth of meals can be provided through non-congregate feeding?

Program operators who utilize multiple day meal issuance may provide up to 10 calendar days' worth of meals during a single meal distribution period.

Program operators who utilize bulk meal distribution may provide up to 5 calendar days worth of bulk food items during a single meal distribution period.

What types of food items can be included as part of bulk meal distribution?

Title 7 Code of Federal Regulations , Section 225.16(i)(3)(iv) states that heating and warming of bulk food items must be minimal. Bulk food items should not require cooking in order to be consumed safely.

What data can be used to identify feeding sites as rural?

Are program integrity plans recommended or required.

Federal regulations require that sponsors have procedures in place to protect program integrity. The CDE has developed a program integrity checklist and attestation statement that can be utilized to develop written program integrity procedures.

Operators of the Summer Food Service program may send questions related to non-congregate feeding to the CDE at [email protected] . Operators of the Seamless Summer Option may submit questions to [email protected] .

In Python programming, Operators in general are used to perform operations on values and variables. These are standard symbols used for logical and arithmetic operations. In this article, we will look into different types of Python operators.

OPERATORS: These are the special symbols. Eg- + , * , /, etc.
OPERAND: It is the value on which the operator is applied.

Arithmetic Operators in Python

Python Arithmetic operators are used to perform basic mathematical operations like addition, subtraction, multiplication , and division .

In Python 3.x the result of division is a floating-point while in Python 2.x division of 2 integers was an integer. To obtain an integer result in Python 3.x floored (// integer) is used.

Example of Arithmetic Operators in Python

Division operators.

In Python programming language Division Operators allow you to divide two numbers and return a quotient, i.e., the first number or number at the left is divided by the second number or number at the right and returns the quotient.

There are two types of division operators:

Float division

Floor division

The quotient returned by this operator is always a float number, no matter if two numbers are integers. For example:

Example: The code performs division operations and prints the results. It demonstrates that both integer and floating-point divisions return accurate results. For example, ’10/2′ results in ‘5.0’ , and ‘-10/2’ results in ‘-5.0’ .

Integer division( Floor division)

The quotient returned by this operator is dependent on the argument being passed. If any of the numbers is float, it returns output in float. It is also known as Floor division because, if any number is negative, then the output will be floored. For example:

Example: The code demonstrates integer (floor) division operations using the // in Python operators . It provides results as follows: ’10//3′ equals ‘3’ , ‘-5//2’ equals ‘-3’ , ‘ 5.0//2′ equals ‘2.0’ , and ‘-5.0//2’ equals ‘-3.0’ . Integer division returns the largest integer less than or equal to the division result.

Precedence of Arithmetic Operators in Python

The precedence of Arithmetic Operators in Python is as follows:

P – Parentheses
E – Exponentiation
M – Multiplication (Multiplication and division have the same precedence)
D – Division
A – Addition (Addition and subtraction have the same precedence)
S – Subtraction

The modulus of Python operators helps us extract the last digit/s of a number. For example:

x % 10 -> yields the last digit
x % 100 -> yield last two digits

Arithmetic Operators With Addition, Subtraction, Multiplication, Modulo and Power

Here is an example showing how different Arithmetic Operators in Python work:

Example: The code performs basic arithmetic operations with the values of ‘a’ and ‘b’ . It adds (‘+’) , subtracts (‘-‘) , multiplies (‘*’) , computes the remainder (‘%’) , and raises a to the power of ‘b (**)’ . The results of these operations are printed.

Note: Refer to Differences between / and // for some interesting facts about these two Python operators.

Comparison of Python Operators

In Python Comparison of Relational operators compares the values. It either returns True or False according to the condition.

= is an assignment operator and == comparison operator.

Precedence of Comparison Operators in Python

In Python, the comparison operators have lower precedence than the arithmetic operators. All the operators within comparison operators have the same precedence order.

Example of Comparison Operators in Python

Let’s see an example of Comparison Operators in Python.

Example: The code compares the values of ‘a’ and ‘b’ using various comparison Python operators and prints the results. It checks if ‘a’ is greater than, less than, equal to, not equal to, greater than, or equal to, and less than or equal to ‘b’ .

Logical Operators in Python

Python Logical operators perform Logical AND , Logical OR , and Logical NOT operations. It is used to combine conditional statements.

Precedence of Logical Operators in Python

The precedence of Logical Operators in Python is as follows:

Logical not
logical and

Example of Logical Operators in Python

The following code shows how to implement Logical Operators in Python:

Example: The code performs logical operations with Boolean values. It checks if both ‘a’ and ‘b’ are true ( ‘and’ ), if at least one of them is true ( ‘or’ ), and negates the value of ‘a’ using ‘not’ . The results are printed accordingly.

Bitwise Operators in Python

Python Bitwise operators act on bits and perform bit-by-bit operations. These are used to operate on binary numbers.

Precedence of Bitwise Operators in Python

The precedence of Bitwise Operators in Python is as follows:

Bitwise NOT
Bitwise Shift
Bitwise AND
Bitwise XOR

Here is an example showing how Bitwise Operators in Python work:

Example: The code demonstrates various bitwise operations with the values of ‘a’ and ‘b’ . It performs bitwise AND (&) , OR (|) , NOT (~) , XOR (^) , right shift (>>) , and left shift (<<) operations and prints the results. These operations manipulate the binary representations of the numbers.

Python Assignment operators are used to assign values to the variables.

Let’s see an example of Assignment Operators in Python.

Example: The code starts with ‘a’ and ‘b’ both having the value 10. It then performs a series of operations: addition, subtraction, multiplication, and a left shift operation on ‘b’ . The results of each operation are printed, showing the impact of these operations on the value of ‘b’ .

Identity Operators in Python

In Python, is and is not are the identity operators both are used to check if two values are located on the same part of the memory. Two variables that are equal do not imply that they are identical.

Example Identity Operators in Python

Let’s see an example of Identity Operators in Python.

Example: The code uses identity operators to compare variables in Python. It checks if ‘a’ is not the same object as ‘b’ (which is true because they have different values) and if ‘a’ is the same object as ‘c’ (which is true because ‘c’ was assigned the value of ‘a’ ).

Membership Operators in Python

In Python, in and not in are the membership operators that are used to test whether a value or variable is in a sequence.

Examples of Membership Operators in Python

The following code shows how to implement Membership Operators in Python:

Example: The code checks for the presence of values ‘x’ and ‘y’ in the list. It prints whether or not each value is present in the list. ‘x’ is not in the list, and ‘y’ is present, as indicated by the printed messages. The code uses the ‘in’ and ‘not in’ Python operators to perform these checks.

in Python, Ternary operators also known as conditional expressions are operators that evaluate something based on a condition being true or false. It was added to Python in version 2.5.

It simply allows testing a condition in a single line replacing the multiline if-else making the code compact.

Syntax : [on_true] if [expression] else [on_false]

Examples of Ternary Operator in Python

The code assigns values to variables ‘a’ and ‘b’ (10 and 20, respectively). It then uses a conditional assignment to determine the smaller of the two values and assigns it to the variable ‘min’ . Finally, it prints the value of ‘min’ , which is 10 in this case.

In Python, Operator precedence and associativity determine the priorities of the operator.

Operator Precedence in Python

This is used in an expression with more than one operator with different precedence to determine which operation to perform first.

Let’s see an example of how Operator Precedence in Python works:

Example: The code first calculates and prints the value of the expression 10 + 20 * 30 , which is 610. Then, it checks a condition based on the values of the ‘name’ and ‘age’ variables. Since the name is “ Alex” and the condition is satisfied using the or operator, it prints “Hello! Welcome.”

Operator Associativity in Python

If an expression contains two or more operators with the same precedence then Operator Associativity is used to determine. It can either be Left to Right or from Right to Left.

The following code shows how Operator Associativity in Python works:

Example: The code showcases various mathematical operations. It calculates and prints the results of division and multiplication, addition and subtraction, subtraction within parentheses, and exponentiation. The code illustrates different mathematical calculations and their outcomes.
