/* Swapping Two Numbers Using Two Variables In C - SWAPTWONUMBERS.C */

#include<stdio.h>
#include<conio.h>
void main()
{
    int num1, num2 ;
    clrscr() ;
    printf("Enter two numbers : ") ;
    scanf("%d %d", &num1, &num2) ;
    printf("\nBefore swapping : \n\n") ;
    printf("num1= %d \t num2 = %d", num1, num2) ;

    /* Swapping Two Numbers Logic */
    num1 = num1 + num2 ;
    num2 = num1 - num2 ;
    num1 = num1 - num2 ;
    printf("\n\nAfter swapping : \n\n") ;
    printf("num1 = %d \t num2 = %d", num1, num2) ;
    getch() ;
}

C Program To Swap Two Numbers Output

After you compile and run the above program your C compiler asks you to enter two numbers, then it will show output before swapping and after swapping two numbers like below expected output.

Enter two numbers : 10 20

Before swapping :
num1 = 10 num2 = 20
