Swapping Two Numbers in C Language

 Swapping Two Numbers in C Language

Introduction

Swapping values of two variables is a common task. This program demonstrates swapping using a temporary variable.


#include <stdio.h>
int main() {
    int a, b, temp;
    printf("Enter two integers: ");
    scanf("%d %d", &a, &b);
    temp = a;
    a = b;
    b = temp;
    printf("After swapping: a = %d, b = %d", a, b);
    return 0;
}

Explanation

  • temp = a;: Stores the value of a in temp.

  • a = b;: Assigns the value of b to a.

  • b = temp;: Assigns the original value of a to b.
