Assignment Operator in C

0 29

The assignment operator (=) sets a variable's value to a specified expression.

It takes the value on its right and assigns it to the variable on its left.

Syntax:

variable_name = value;

The assignment operator is fundamental in C programming.

It assigns the value of the expression on the right-hand side to the variable on the left-hand side.

Examples:

1 Basic Assignment

Assigning an integer value to a variable.

// Program to Assigning an integer value to a variable.
#include<stdio.h> 
int main() {
    int num;
    num = 10;
    printf("The value of num is: %d\n", num);
    return 0;
}

Output:

The value of num is: 10

2Assignment with Arithmetic Operation

Assigning the result of an arithmetic operation to a variable.

// program for Assignment with Arithmetic Operation
#include<stdio.h> 

int main() {
   int a = 5, b = 3, result;
    
    result = a + b;
    
    printf("The result of %d + %d is: %d\n", a, b, result);
    return 0;
}

Output:

The result of 5 + 3 is: 8

3Assignment with Conditional Operation

Assigning a value based on a condition.

// Program for Assigning a value based on a condition.
#include<stdio.h> 
int main() {
    int marks = 75;
    char grade;
    grade = (marks >= 60) ? 'A' : 'B';
    printf("The grade is: %c\n", grade);
    return 0;
}

Output:

The grade is: A

4Multiple Assignments

Assigning values to multiple variables in one line.

// program for Assigning values to multiple variables in one line.
#include<stdio.h> 
int main() {
    int x, y, z;
    x = y = z = 10;
    printf("x = %d, y = %d, z = %d\n", x, y, z);
    return 0;

}

Output:
