Assignment operators.

Assignment operators modify the value of the object.

[ edit ] Definitions

Copy assignment replaces the contents of the object a with a copy of the contents of b ( b is not modified). For class types, this is performed in a special member function, described in copy assignment operator .

For non-class types, copy and move assignment are indistinguishable and are referred to as direct assignment .

Compound assignment replace the contents of the object a with the result of a binary operation between the previous value of a and the value of b .

[ edit ] Assignment operator syntax

The assignment expressions have the form

  • ↑ target-expr must have higher precedence than an assignment expression.
  • ↑ new-value cannot be a comma expression, because its precedence is lower.

[ edit ] Built-in simple assignment operator

For the built-in simple assignment, the object referred to by target-expr is modified by replacing its value with the result of new-value . target-expr must be a modifiable lvalue.

The result of a built-in simple assignment is an lvalue of the type of target-expr , referring to target-expr . If target-expr is a bit-field , the result is also a bit-field.

[ edit ] Assignment from an expression

If new-value is an expression, it is implicitly converted to the cv-unqualified type of target-expr . When target-expr is a bit-field that cannot represent the value of the expression, the resulting value of the bit-field is implementation-defined.

If target-expr and new-value identify overlapping objects, the behavior is undefined (unless the overlap is exact and the type is the same).

In overload resolution against user-defined operators , for every type T , the following function signatures participate in overload resolution:

For every enumeration or pointer to member type T , optionally volatile-qualified, the following function signature participates in overload resolution:

For every pair A1 and A2 , where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signature participates in overload resolution:

[ edit ] Built-in compound assignment operator

The behavior of every built-in compound-assignment expression target-expr   op   =   new-value is exactly the same as the behavior of the expression target-expr   =   target-expr   op   new-value , except that target-expr is evaluated only once.

The requirements on target-expr and new-value of built-in simple assignment operators also apply. Furthermore:

  • For + = and - = , the type of target-expr must be an arithmetic type or a pointer to a (possibly cv-qualified) completely-defined object type .
  • For all other compound assignment operators, the type of target-expr must be an arithmetic type.

In overload resolution against user-defined operators , for every pair A1 and A2 , where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signatures participate in overload resolution:

For every pair I1 and I2 , where I1 is an integral type (optionally volatile-qualified) and I2 is a promoted integral type, the following function signatures participate in overload resolution:

For every optionally cv-qualified object type T , the following function signatures participate in overload resolution:

C Assignment Operators

  • 6 contributors

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 .

4.5: Assignment Operator

  • Last updated

  • Page ID 10258

  • Kenneth Leroy Busbee
  • Houston Community College via OpenStax CNX

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.

Assignment operators

Assignment operators modify the value of the object.

Explanation

copy assignment operator replaces the contents of the object a with a copy of the contents of b ( b is not modified). For class types, this is a special member function, described in copy assignment operator .

move assignment operator replaces the contents of the object a with the contents of b , avoiding copying if possible ( b may be modified). For class types, this is a special member function, described in move assignment operator . (since C++11)

For non-class types, copy and move assignment are indistinguishable and are referred to as direct assignment .

compound assignment operators replace the contents of the object a with the result of a binary operation between the previous value of a and the value of b .

Builtin direct assignment

The direct assignment expressions have the form

For the built-in operator, lhs may have any non-const scalar type and rhs must be implicitly convertible to the type of lhs .

The direct assignment operator expects a modifiable lvalue as its left operand and an rvalue expression or a braced-init-list (since C++11) as its right operand, and returns an lvalue identifying the left operand after modification.

For non-class types, the right operand is first implicitly converted to the cv-unqualified type of the left operand, and then its value is copied into the object identified by left operand.

When the left operand has reference type, the assignment operator modifies the referred-to object.

If the left and the right operands identify overlapping objects, the behavior is undefined (unless the overlap is exact and the type is the same)

In overload resolution against user-defined operators , for every type T , the following function signatures participate in overload resolution:

For every enumeration or pointer to member type T , optionally volatile-qualified, the following function signature participates in overload resolution:

For every pair A1 and A2, where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signature participates in overload resolution:

Builtin compound assignment

The compound assignment expressions have the form

The behavior of every builtin compound-assignment expression E1 op = E2 (where E1 is a modifiable lvalue expression and E2 is an rvalue expression or a braced-init-list (since C++11) ) is exactly the same as the behavior of the expression E1 = E1 op E2 , except that the expression E1 is evaluated only once and that it behaves as a single operation with respect to indeterminately-sequenced function calls (e.g. in f ( a + = b, g ( ) ) , the += is either not started at all or is completed as seen from inside g ( ) ).

In overload resolution against user-defined operators , for every pair A1 and A2, where A1 is an arithmetic type (optionally volatile-qualified) and A2 is a promoted arithmetic type, the following function signatures participate in overload resolution:

For every pair I1 and I2, where I1 is an integral type (optionally volatile-qualified) and I2 is a promoted integral type, the following function signatures participate in overload resolution:

For every optionally cv-qualified object type T , the following function signatures participate in overload resolution:

  • Assignment operators

An assignment operator assigns a value to its left operand based on the value of its right operand.

The basic assignment operator is equal ( = ), which assigns the value of its right operand to its left operand. That is, x = y assigns the value of y to x . The other assignment operators are usually shorthand for standard operations, as shown in the following definitions and examples.

Simple assignment operator which assigns a value to a variable. The assignment operation evaluates to the assigned value. Chaining the assignment operator is possible in order to assign a single value to multiple variables. See the example.

Addition assignment

The addition assignment operator adds the value of the right operand to a variable and assigns the result to the variable. The types of the two operands determine the behavior of the addition assignment operator. Addition or concatenation is possible. See the addition operator for more details.

Subtraction assignment

The subtraction assignment operator subtracts the value of the right operand from a variable and assigns the result to the variable. See the subtraction operator for more details.

Multiplication assignment

The multiplication assignment operator multiplies a variable by the value of the right operand and assigns the result to the variable. See the multiplication operator for more details.

Division assignment

The division assignment operator divides a variable by the value of the right operand and assigns the result to the variable. See the division operator for more details.

Remainder assignment

The remainder assignment operator divides a variable by the value of the right operand and assigns the remainder to the variable. See the remainder operator for more details.

Exponentiation assignment

This is an experimental technology, part of the ECMAScript 2016 (ES7) proposal. Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future version of browsers as the spec changes.

The exponentiation assignment operator evaluates to the result of raising first operand to the power second operand. See the exponentiation operator for more details.

Left shift assignment

The left shift assignment operator moves the specified amount of bits to the left and assigns the result to the variable. See the left shift operator for more details.

Right shift assignment

The right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable. See the right shift operator for more details.

Unsigned right shift assignment

The unsigned right shift assignment operator moves the specified amount of bits to the right and assigns the result to the variable. See the unsigned right shift operator for more details.

Bitwise AND assignment

The bitwise AND assignment operator uses the binary representation of both operands, does a bitwise AND operation on them and assigns the result to the variable. See the bitwise AND operator for more details.

Bitwise XOR assignment

The bitwise XOR assignment operator uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable. See the bitwise XOR operator for more details.

Bitwise OR assignment

The bitwise OR assignment operator uses the binary representation of both operands, does a bitwise OR operation on them and assigns the result to the variable. See the bitwise OR operator for more details.

Left operand with another assignment operator

In unusual situations, the assignment operator (e.g. x += y ) is not identical to the meaning expression (here x = x + y ). When the left operand of an assignment operator itself contains an assignment operator, the left operand is evaluated only once. For example:

Just like Arithmetic Operators, C++ has Assignment Operators. In order to give value to the variable in the program, an operator is needed. This function is provided by the Assignment Operators. Assignment Operators in programming languages are pre-defined operators which are used to assign values to the variables. Let us look at these Assignment operators in more detail.

assignment operators

  • Assignment Operators are used to assigning the results of an expression or constant to a variable.
  • In order to assign values to a variable, we use the Assignment Operator  in the programming language.

Assignment Operator is a type of Binary Operator wherein it needs two operands to function. The left side operand is the variable and the right side of the operand is the value to be assigned.

The symbol which is used by the Assignment Operator is ‘ = ’.

Copy Code Copied Use a different Browser

The assignment operator can be used within any valid expression. An expression can be a combination of variables, constants, and operators arranged as per the syntax and precedence levels of the programming language.

During the use of the assignment operator, always the right-hand side of the operator is computed first, and then it is assigned to the variable defined on the left-hand side of the statement.

Note:  The source (right-hand side) and destination (left-hand side) should always be of the same data type.

Types of Assignment Operators

In C++, there are 2 categories of Assignment Operators

  • Simple Assignment Operator
  • Compound Assignment Operator

Simple Assignment Operator (=) :

This is the usual assignment operator. Simple-assignment operator assigns its right operand to its left operand. In easy terms, this operator is used to assign the value on the right to the variable on the left.

Compound Assignment Operator:

These type of Operators are also known as Short-hand assignment operators.

Its syntax is,

where OP is a binary operator and is known as short-hand assignment operator.

While first initializing the variable, we cannot use the Short-hand operators. This will give a declaration error at the compile time of the program. Let’s understand this by looking at an example –

Compile-time Error. Value of variable ‘a’ not defined.

In the above program, we can see that in the initialization statement, we did not assign the value of 10 to the variable ‘a’ but instead we used the shorthand assignment operator which means

But the value of ‘a’ has not been defined. The compiler does not know the value stored in the location of variable ‘a’. Hence a compile-time error occurs.

Types of Assignment Operators in Java

  • Simple Assignment Operator: The Simple Assignment Operator is used with the "=" sign, where the operand is on the left side and the value is on the right. The right-side value must be of the same data type as that defined on the left side.
  • Compound Assignment Operator:  Compound assignment operators combine arithmetic operations with assignments. They provide a concise way to perform an operation and assign the result to the variable in one step. The Compound Operator is utilized when +,-,*, and / are used in conjunction with the = operator.

1. Simple Assignment Operator (=):

The equal sign (=) is the basic assignment operator in Java. It is used to assign the value on the right-hand side to the variable on the left-hand side.

assignment operators types

To fully comprehend the assignment operators in Python, it is important to have a basic understanding of what operators are. Operators are utilized to carry out a variety of operations, including mathematical, bitwise, and logical operations, among others, by connecting operands. Operands are the values that are acted upon by operators. In Python, the assignment operator is used to assign a value to a variable. The assignment operator is represented by the equals sign (=), and it is the most commonly used operator in Python. In this article, we will explore the assignment operator in Python, how it works, and its different types.

What is an Assignment Operator in Python?

The assignment operator in Python is used to assign a value to a variable. The assignment operator is represented by the equals sign (=), and it is used to assign a value to a variable. When an assignment operator is used, the value on the right-hand side is assigned to the variable on the left-hand side. This is a fundamental operation in programming, as it allows developers to store data in variables that can be used throughout their code.

For example, consider the following line of code:

Explanation: In this case, the value 10 is assigned to the variable a using the assignment operator. The variable a now holds the value 10, and this value can be used in other parts of the code. This simple example illustrates the basic usage and importance of assignment operators in Python programming.

Types of Assignment Operator in Python

There are several types of assignment operator in Python that are used to perform different operations. Let’s explore each type of assignment operator in Python in detail with the help of some code examples.

1. Simple Assignment Operator (=)

The simple assignment operator is the most commonly used operator in Python. It is used to assign a value to a variable. The syntax for the simple assignment operator is:

Here, the value on the right-hand side of the equals sign is assigned to the variable on the left-hand side. For example

Operators: What Role Do They Play in Programming?

Learn about different types of operators and why they’re essential in computer programming, along with the different operator types in three popular languages.

[Featured Image] A programmer wearing headphones is working on her laptop with types of operators.

Operators are symbols with defined functions. Programmers use these symbols to tell the interpreter or compiler in high-level computer languages, such as C++, Java, and Python, to perform a particular action. These symbols form the program's foundation, allowing you to perform various actions ranging from simple maths to complex encryption. 

Operators are essential for performing calculations, assigning specific values to variables, and making condition-based decisions. You can learn more about operator types and how they work within three popular computer languages. 

Types of operators

Different types perform different tasks within the programme. You can choose from three main types of operators, each with unique functions and capabilities. 

Arithmetic operator 

Arithmetic operators allow computers to perform mathematical calculations on specific values. For example, you might write ‘A+B = 40’ or ‘A*B = 100’. Common arithmetic  operators include:

Addition: +

Subtraction:  -

Multiplication: *

Division: /

Integer division: DIV

Remainder: MOD

Relational operator 

Relational operators facilitate condition testing, allowing you to create variables and assign them values. For example, if A equals 45 and B equals 50, you might write A < B or A is less than B. That < symbol is a relational operator that produces true or false results. Common relational operators include: 

Assignment: =

Equivalence: ==

Less than: <

Greater than: >

Less than or equal to: <=

Greater than or equal to: >=

Does not equal: !=

Logical operator 

Logical operators allow programmers to gain increasingly complex computer-based decisions by combining relational operators. For example, with the logical AND operator, if A equals 10 and B equals zero, and you write ‘A AND B is false,’ the condition is true if both variables are the same. If you use the logical OR operator and just one of the variables is something other than zero, ‘A OR B is true’ would be true. 

You can reverse the variable’s logical state with the local NOT operator. So, what would otherwise be true becomes false and vice versa.

Common operators include:

AND (&&)

Types of operators in C++ 

C++ uses more than five types of operators to carry out different functions. You may also use multiple operators in one expression. In these cases, C++ has established operator precedence to determine how things get evaluated. For example, postfix operators work left to right. So do additive, multiplicative, and shift operators. Unary, conditional, and assignment operators have precedence from right to left. Types of C++ operators include:

Assignment: These operators assign the left-hand side operand the right-hand side operand's value and are variations on = , including += (addition assignment), -= (subtraction assignment), *= (multiplication assignment), /= (division assignment), and %= (modulus assignment)

Arithmetic: These operators allow you to perform calculations between two values using symbols such as + (addition), - (subtraction), * (multiplication), / (division), % (modulus), ++ (increment), and — (decrement)

Relational: These operators perform comparisons between operands and include symbols like == equal to), > (greater than), < (less than), != (not equal to), >= (greater than or equal), and <= (less than or equal to)

Logical: These C++ operators check conditions and expressions to determine whether they are true or false to aid decision-making. They include symbols like && (logical AND operator if all operands are true), || (logical OR operator if at least one operand is true), and ! (logical NOT operator that reverses the logical state from true to false or false to true)

Bitwise: These C++ operators allow you to perform operations by treating operands like a string of bits for output in decimals. Symbols include & (logical AND operator performs AND on the bits of two operands), | (logical OR operator performs OR on the bits of two operands),  ^ (bitwise XOR operator performs XOR on all bits of two numbers), ~ (bitwise one complement inverts all an operand's bits), << (binary left shift shifts the bits in one operand using the second operand as a determinant), >> (binary right shift shifts the bits in one operand using the second operand as a determinant)

Other: C++ also has other operators, including:

Size of , which determines a variable's size

Conditional , a ternary operator that evaluates test conditions and puts a code block into place based on test results

Comma, which triggers the start of an operational sequence

Types of Operators in Java 

In Java, you use operators to perform local operations and mathematical tasks. You can break them into three categories based on the number of operands or the entities they operate upon and use. Unary operators work on one operand, binary operators work on two operands, and ternary operators utilise three operands to carry out the task. Java’s operators include: 

Assignment: This binary operator uses the symbol = to assign the value of the operand on the right of an expression to the one on the left.

Arithmetic: These operators may be unary and binary and get placed in three categories, including primary, increment and decrement, and shorthand. Symbols include + (addition), - (subtraction), * (multiplication), / (division), % (modulus), + (unary plus to indicate a positive number), or - (unary minus to indicate a negative number)

Increment and decrement include ++ (increment) and — (decrement) to increment or decrement operands' values

Shorthand operators pair with assignment operators, making it possible to write less code by including symbols such as += (addition assignment), -= (subtraction assignment), and *= (multiplication assignment)

Relational: These binary operators work as comparison or equality operators and include symbols such as > (greater than), < (less than), >= (greater than equal to), <= (less than equal to), == (equal equal to), and != (not equal to)

Logical: Java operators in this category work on boolean operands to perform functions using symbols like & (logical AND), | (logical OR), ! (logical NOT), ^ (logical XOR), == (equal equal to), != (not equal to), && (conditional AND), and || (conditional OR)

Bitwise: To manipulate an operand's bits, you can use these operators, which include symbols like & (bitwise AND), | (bitwise OR), ~ (bitwise NOT), and ^ (bitwise XOR)

Types of Operators in Python 

In Python, operators are symbols that perform specific tasks. The operator you choose for any operation changes the results, allowing you to manipulate operands' values. Python’s operators include: 

Arithmetic: These operators include symbols that perform mathematical functions, including addition ( + ), subtraction ( - ), multiplication ( * ), division ( / ), and modulus ( % )

Assignment: These operators allow you to assign values and include various symbols, including = (X=2), -= (X-=2), += (X+=2), and *= (X*=2)

Comparison: When you want to compare two values, you will use symbols such as = (equal), != (not equal), > (greater than), and < (less than)

Logical: When you want to compare conditional statements, you can use operators such as x>2 and x>3 , x>2 or x>3 , or not (x>2 and x>3)

Membership: These are operators that allow you to calculate and figure out if an object contains a sequence, including in , which comes back true in the presence of the sequence, or not in , which comes back as true if the sequence doesn't exist

Bitwise: These operators compare binary values using symbols such as & (sets all bits to 1 if all bits are 1),  | (sets all bits to 1 if one of the bits is 1), or ^ (sets all bits for 1 if one of the bits is 1). To invert all bits, you could use ~ (Bitwise NOT), or you can use operators to shift left ( << ) or shift right ( >> )

Identity: The two identity operators include is (comes back true if both variables are the same objects) and is not (comes back true if the variables are different objects)

What careers use operators

Operators are commonly used in computer programming, making programmers the primary career that uses them. You may use operators in other professions that require coding, including roles such as data analysts or data scientists. 

Software engineers, data scientists, and data analysts are among India's most in-demand jobs [ 1 ]. Many applicants find positions in cities like Bangalore, sometimes called India’s Silicon Valley. Mumbai, Kolkata, and Delhi are common locations for these types of jobs. According to Glassdoor India, as of March 2024, the average base salaries for these careers are as follows: 

Programmers: ₹4,00,000

Data scientists: ₹12,59,927

Data analysts: ₹8,47,000 

Now that you’re more familiar with the types of operators and how they work in different languages, continue learning to increase your skills and achieve your goals. For example, if you’re new to programming, consider earning a Professional Certificate, such as Google IT with Python , or completing a Specialisation like Learn SQL Basics for Data Science offered by the University of California Davis on Coursera.

If you have programming experience and want to brush up on operators, complete a Guided Project like JavaScript Variables and Assignment Operators on Coursera Project Network or Looker Functions and Operators , a Project that's part of Google Cloud Training—both on Coursera.
