C Program to swap two numbers without using third variable




C Program to swap two numbers without using third variable



#include <stdio.h>

int main()
{
    int x,y;
    printf("\n Enter x value :");
    scanf("%d",&x);
    printf("\n Enter y value :");
    scanf("%d",&y);
    printf("\n Before swapping x value: %d",x);
    printf("\n Before swapping y value: %d",y);
    x=x+y;
    y=x-y;
    x=x-y;
    printf("\n After swapping x value: %d",x);
    printf("\n After swapping y value: %d",y);
    return 0;
}


Output:
Enter x value :500

 Enter y value :800

 Before swapping x value: 500
 Before swapping y value: 800

 After swapping x value: 800
 After swapping y value: 500
