Swapping Values of Two Variables in C

Swapping the values of two variables is a common operation in programming, and it serves various purposes across different applications. In this article, we are going to swap the values of two variables in C.

Problem Statement- WAP that swaps values of two variables using a third variable.

Swapping Values of Two Variables by Using Third Variable

The traditional and straightforward method for swapping values involves using a third variable as a temporary storage space. Let’s write a C program that swaps the values of two variables using a third variable.

C Program

#include <stdio.h>
void main()
{
    int a = 1, b = 2;
    printf("Orignal values : a =%d , b= %d\n ", a, b);
    // Swap values using a third variable
    int temp = a;
    a = b;
    b = temp;
    printf("Swapped values : a =%d , b= %d\n ", a, b);
}

Output

The above C program performs swapping the values of two variables by using a third variable. As you progress in your programming journey, you may encounter more advanced methods for variable swapping.
