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 .

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.

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. 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';

Assignment Operator in C

Using assignment operators, we can assign value to the variables.

Equality sign (=) is used as an assignment operator in C.

Here, value 5 has assigned to the variable var.

Here, value of a has assigned to the variable b . Now, both a and b will hold value 10 .

Basically, the value of right-side operand will be assigned to the left side operand.

Assignment Operators in C

We use this type of operator to transform as well as assign the values to any variable in an operation. In any given assignment operator, the right side is a value, and the left side is a variable. The value present on the right side of the operator must have the same data type as that of the variable present on the left side. In any other case, the compiler raises an error.

In this article, we will take a look into the Assignment Operators in C according to the GATE Syllabus for CSE (Computer Science Engineering) . Read ahead to know more.

Types of Assignment Operators in C

An assignment operator is basically a binary operator that helps in modifying the variable to its left with the use of the value to its right. We utilize the assignment operators to transform and assign values to any variables.

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

• basic assignment ( = )
• subtraction assignment ( -= )
• addition assignment ( += )
• division assignment ( /= )
• multiplication assignment ( *= )
• modulo assignment ( %= )
• bitwise XOR assignment ( ^= )
• bitwise OR assignment ( |= )
• bitwise AND assignment ( &= )
• bitwise right shift assignment ( >>= )
• bitwise left shift assignment ( <<= )

Working of Assignment Operators in C

Here is a table that discusses, in brief, all the Assignment operators that the C language supports:

Example of Assignment Operators in C

Let us look at an example to understand how these work in a code:

#include <stdio.h>

int x = 21;

printf(“Line A – = Example of the Value of y = %d\n”, y );

printf(“Line B – -= Example of the Value of y = %d\n”, y );

printf(“Line C – += Example of the Value of c = %d\n”, c );

printf(“Line D – /= Example of the Value of y = %d\n”, y );

printf(“Line E – *= Example of the Value of y = %d\n”, y );

y <<= 2;

printf(“Line F – <<= Example of the Value of y = %d\n”, y );

printf(“Line G – %= Example of the Value of y = %d\n”, y );

y &= 2;

printf(“Line H – &= Example of the Value of y = %d\n”, y );

y >>= 2;

printf(“Line I – >>= Example of the Value of y = %d\n”, y );

printf(“Line J – |= Example of the Value of y = %d\n”, y );

printf(“Line K – ^= Example of the Value of y = %d\n”, y );

The compilation and execution of the program mentioned above will produce a result as follows:

Line A – = Example of the Value of y = 21

Line B – -= Example of the Value of y = 21

Line C – += Example of the Value of y = 42

Line D – /= Example of the Value of y = 21

Line E – *= Example of the Value of y = 441

Line F – <<= Example of the Value of y = 44

Line G – %= Example of the Value of y = 11

Line H – &= Example of the Value of y = 2

Line I – >>= Example of the Value of y = 11

Line J – |= Example of the Value of y = 2

Line K – ^= Example of the Value of y = 0

Here is another example of how the assignment operators work in the C language:

int y = 10;

printf(“z = x + y = %d \n”,z);

printf(“z += x = %d \n”,z);

printf(“z -= x = %d \n”,z);

printf(“z *= x = %d \n”,z);

printf(“z /= x = %d \n”,z);

printf(“z %= x = %d \n”,z);

c &= x ;

printf(“c &= x = %d \n”,z);

printf(“z ^= x = %d \n”,z);

printf(“z |= x = %d \n”,z);

z <<= 2 ;

printf(“z <<= 2 = %d \n”,z);

z >>= 2 ;

printf(“z >>= 2 = %d \n”,z);

The output generated here will be:

z = x + y = 15

z += x = 20

z -= x = 15

z *= x = 75

z &= x = 0

z ^= x = 10

z |= x = 10

z <<= 2 = 40

z >>= 2 = 10

z >>= 2 = 2

Practice Problems on Assignment Operators in C

1. What would be the output obtained from the program given below?

#include<stdio.h>

p += p += p += 3;

printf(“%d”,p);

Answer – A. 20

p+=p+=p+=3; it can written as p+=p+=p=p+3; p=2; Or, p+=p+=5; p=5; Or, p+=p=5+5; p=5; Or, p+=10; p=10; Or, p=p+10; p=10; Or, p=20. So, finally p=20.

2. Which of these is an invalid type of assignment operator?

D. None of these

Answer – D. None of these

All of these are valid types of assignment operators.

How does the /= operator work? Is it a combination of two other operators?

Yes, the /+ operator is a combination of the = and / operators. The / operator divides the current value of the available variable first on the left using the available value on the right. It then assigns the obtained result to the available variable on the left side.

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

The = operator is the most basic one used in the C language. We use this operator to assign the value available in the right to the value mentioned on the left side of the operator.

Assignment Operator in C Definition and Usage

The assignment operator in C is denoted with an equal sign (=) and is used to assign a value to a variable. The left operand is the variable, and the right operand is the value or expression to be assigned to that variable.

int main() { int x; x = 5; printf("The value of x is: %d", x); return 0; } ``` In this example, the assignment operator (=) assigns the value 5 to the variable x, which is then printed using the `printf()` function.

Basics of Assignment Operator in C

It is essential to understand basic usage and functionality of the assignment operator in C: - Variables must be declared before they can be assigned a value. - The data type on the right-hand side of the operator must be compatible with the data type of the variable on the left-hand side. Here are some more examples of using the assignment operator in C:

int a = 10; // Declare and assign in a single line float b = 3.14; char c = 'A';

Additionally, you can use the assignment operator with various arithmetic, relational, and logical operators:

`+=`: Add and assign

`-=`: Subtract and assign

`*=`: Multiply and assign

`/=`: Divide and assign

For example: int x = 5; x += 2; // Equivalent to x = x + 2; The value of x becomes 7

Importance of Assignment Operator in Computer Programming

The assignment operator in C plays a crucial role in computer programming. Its significance includes:

- Initialization of variables: The assignment operator is used to give an initial value to a variable, as demonstrated in the earlier examples.

- Modification of variable values: It allows you to change the value of a variable throughout the program. For example, you can use the assignment operator to increment the value of a counter variable in a loop.

- Expressions: The assignment operator is often used in expressions, such as calculating and storing the result of an arithmetic operation.

Example: Using the assignment operator with arithmetic operations:

#include int main() { int a = 10, b = 20, sum; sum = a + b; printf("The sum of a and b is: %d", sum); return 0; }

In this example, the assignment operator is used to store the result of the arithmetic operation `a + b` in the variable `sum`.

In conclusion, the assignment operator in C is an essential tool for computer programming. Understanding its definition, usage, and importance will significantly improve your programming skills and enable you to create more efficient and effective code.

Different Types of Assignment Operators in C

Compound assignment operators in c.

Compound assignment operators in C combine arithmetic, Bit manipulation, or other operations with the basic assignment operator. This enables you to perform certain calculations and assignments of new values to variables in a single statement. Compound assignment operators are efficient, as they perform the operation and the assignment in one step rather than two separate steps. Let's examine the various compound assignment operators in C.

Addition Assignment Operator in C

The addition assignment operator (+=) in C combines the addition operation with the assignment operator, allowing you to increment the value of a variable by a specified amount. It essentially means "add the value of the right-hand side of the operator to the value of the variable on the left-hand side and then assign the new value to the variable". The general syntax for the addition assignment operator in C is: variable += value;

Using the addition assignment operator has some advantages:

- Reduces the amount of code you need: It is more concise and easier to read.

- Increases efficiency: It is faster because it performs the operation and assignment in one step.

Here's an example of the addition assignment operator in C: #include int main() { int a = 5; a += 3; // Equivalent to a = a + 3; The value of a becomes 8 printf("The value of a after addition assignment: %d, a); return 0; }

Compound assignment operators also include subtraction (-=), multiplication (*=), division (/=), modulo (%=), and bitwise operations like AND (&=), OR (|=), and XOR (^=). Their usage is similar to the addition assignment operator in C.

Assignment Operator for String in C

In C programming, strings are Arrays of characters, and dealing with strings requires a careful approach. Direct assignment of a string using the assignment operator (=) is not possible, because arrays cannot be assigned using this operator. To assign a string to a character array, you need to use specific functions provided by the C language or develop your own custom function. Here are two commonly used methods for assigning a string to a character array:

1. Using the `strcpy()` function:

In this example, the `strcpy()` function from the `string.h` library is used to copy the contents of the `source` string into the `destination` character array.

2. Custom assignment function:

In this example, a custom function called `assignString()` is created to assign strings. It iterates through the characters of the `source` string, assigns each character to the corresponding element in the `destination` character array, and stops when it encounters the null character ('\0') at the end of the source string. Understanding assignment operators in C and the various types of assignment operators can help you write more efficient and effective code. It also enables you to work effectively with different data types, including strings and Arrays of characters, which are essential for creating powerful and dynamic software applications.

Practical Examples of Assignment Operator in C

In this section, we will explore some practical examples of the assignment operator in C. Examples will cover simple assignments and discuss usage scenarios for compound assignment operators, as well as demonstrating the implementation of the assignment operator for strings in C.

Assignment Operator in C Example: Simple Assignments

Simple assignment operations in C involve assigning a single value to a variable. Here are some examples of simple assignment operations:

1. Assigning an integer value to a variable: int age = 25;

2. Assigning a floating-point value to a variable: float salary = 50000.75;

3. Assigning a character value to a variable: char grade = 'A';

4. Swapping the values of two variables:

In this swapping example, the assignment operator is used to temporarily store the value of one variable and then exchange the values of two variables.

Usage Scenarios for Compound Assignment Operators

Compound assignment operators in C provide shorthand ways of updating the values of variables with arithmetic, bitwise, or other operations. Here are some common usage scenarios for compound assignment operators:

1. Incrementing a counter variable in a loop: for(int i = 0; i < 10; i += 2) { printf("%d ", i); } Here, the addition assignment operator (+=) is used within a `for` loop to increment the counter variable `i` by 2 at each iteration.

2. Accumulating the sum of elements in an array: #include int main() { int array[] = {1, 2, 3, 4, 5}; int sum = 0; for (int i = 0; i < 5; i++) { sum += array[i]; // Equivalent to sum = sum + array[i]; } printf("Sum of array elements: %d", sum); return 0; } In this example, the addition assignment operator (+=) is used to accumulate the sum of the array elements.

3. Calculating the product of two numbers using bitwise operations:

I n this example, the bitwise AND operation is combined with the addition assignment operator (+=) along with bitwise shift and compound assignment operators to perform multiplication without using the arithmetic `*` operator.

Implementing Assignment Operator for String in C with Examples

As discussed earlier, assigning strings in C requires a different approach, as the assignment operator (=) cannot be used directly. Here are some practical examples that demonstrate how to implement the assignment operator for strings in C:

1. Using the `strcpy()` function from the `string.h` library:

2. Defining a custom function to assign strings, which takes two character pointers as arguments:

These examples showcase the implementation of the assignment operator for strings in C, enabling you to effectively manipulate and work with strings in your C programs. By using built-in C Functions or defining your own custom functions, you can assign strings to character arrays, which allow you to perform various operations on strings, such as concatenation, comparison, substring search, and more.

Assignment Operator in C - Key takeaways

Assignment Operator in C: represented by the equal sign (=), assigns a value to a variable

Compound assignment operators in C: combine arithmetic or bitwise operations with the assignment operator, such as +=, -=, and *=

Addition assignment operator in C: represented by (+=), adds a value to an existing variable and assigns the new value

Assignment operator for String in C : requires specific functions like strcpy() or custom functions, as direct assignment with = is not possible

Assignment Operator in C example: int x = 5; assigns the value 5 to the variable x

Copy assignment operator.

A copy assignment operator is a non-template non-static member function with the name operator = that can be called with an argument of the same class type and copies the content of the argument without mutating the argument.

[ edit ] Syntax

For the formal copy assignment operator syntax, see function declaration . The syntax list below only demonstrates a subset of all valid copy assignment operator syntaxes.

[ edit ] Explanation

The copy assignment operator is called whenever selected by overload resolution , e.g. when an object appears on the left side of an assignment expression.

[ edit ] Implicitly-declared copy assignment operator

If no user-defined copy assignment operators are provided for a class type, the compiler will always declare one as an inline public member of the class. This implicitly-declared copy assignment operator has the form T & T :: operator = ( const T & ) if all of the following is true:

• each direct base B of T has a copy assignment operator whose parameters are B or const B & or const volatile B & ;
• each non-static data member M of T of class type or array of class type has a copy assignment operator whose parameters are M or const M & or const volatile M & .

Otherwise the implicitly-declared copy assignment operator is declared as T & T :: operator = ( T & ) .

Due to these rules, the implicitly-declared copy assignment operator cannot bind to a volatile lvalue argument.

A class can have multiple copy assignment operators, e.g. both T & T :: operator = ( T & ) and T & T :: operator = ( T ) . If some user-defined copy assignment operators are present, the user may still force the generation of the implicitly declared copy assignment operator with the keyword default . (since C++11)

The implicitly-declared (or defaulted on its first declaration) copy assignment operator has an exception specification as described in dynamic exception specification (until C++17) noexcept specification (since C++17)

Because the copy assignment operator is always declared for any class, the base class assignment operator is always hidden. If a using-declaration is used to bring in the assignment operator from the base class, and its argument type could be the same as the argument type of the implicit assignment operator of the derived class, the using-declaration is also hidden by the implicit declaration.

[ edit ] Implicitly-defined copy assignment operator

If the implicitly-declared copy assignment operator is neither deleted nor trivial, it is defined (that is, a function body is generated and compiled) by the compiler if odr-used or needed for constant evaluation (since C++14) . For union types, the implicitly-defined copy assignment copies the object representation (as by std::memmove ). For non-union class types, the operator performs member-wise copy assignment of the object's bases and non-static members, in their initialization order, using built-in assignment for the scalars and copy assignment operator for class types.

[ edit ] Deleted copy assignment operator

An implicitly-declared or explicitly-defaulted (since C++11) copy assignment operator for class T is undefined (until C++11) defined as deleted (since C++11) if any of the following conditions is satisfied:

• T has a non-static data member of a const-qualified non-class type (or possibly multi-dimensional array thereof).
• T has a non-static data member of a reference type.
• T has a potentially constructed subobject of class type M (or possibly multi-dimensional array thereof) such that the overload resolution as applied to find M 's copy assignment operator
• does not result in a usable candidate, or
• in the case of the subobject being a variant member , selects a non-trivial function.

[ edit ] Trivial copy assignment operator

The copy assignment operator for class T is trivial if all of the following is true:

• it is not user-provided (meaning, it is implicitly-defined or defaulted);
• T has no virtual member functions;
• T has no virtual base classes;
• the copy assignment operator selected for every direct base of T is trivial;
• the copy assignment operator selected for every non-static class type (or array of class type) member of T is trivial.

A trivial copy assignment operator makes a copy of the object representation as if by std::memmove . All data types compatible with the C language (POD types) are trivially copy-assignable.

[ edit ] Eligible copy assignment operator

Triviality of eligible copy assignment operators determines whether the class is a trivially copyable type .

[ edit ] Notes

If both copy and move assignment operators are provided, overload resolution selects the move assignment if the argument is an rvalue (either a prvalue such as a nameless temporary or an xvalue such as the result of std::move ), and selects the copy assignment if the argument is an lvalue (named object or a function/operator returning lvalue reference). If only the copy assignment is provided, all argument categories select it (as long as it takes its argument by value or as reference to const, since rvalues can bind to const references), which makes copy assignment the fallback for move assignment, when move is unavailable.

It is unspecified whether virtual base class subobjects that are accessible through more than one path in the inheritance lattice, are assigned more than once by the implicitly-defined copy assignment operator (same applies to move assignment ).

See assignment operator overloading for additional detail on the expected behavior of a user-defined copy-assignment operator.
