#include <stdio.h>

void main()
{
    long i, k;

    printf("Enter two integers \n");
    scanf("%ld %ld", &i, &k);
    printf("\n Before swapping i= %ld and k = %ld", i, k);
    i = i ^ k;
    k = i ^ k;
    i = i ^ k;
    printf("\n After swapping i= %ld and k = %ld", i, k);
}

output:
$ a.out
Enter two integers
45
89

Before swapping i= 45 and k = 89
After swapping i= 89 and k = 45
