Swap Two Number Using Bitwise XOR

#include <stdio.h>

int 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);

    return 0;
}

OUTPUT

Enter two integers
35
96
 
Before swapping i= 35 and k = 96
After swapping i= 96 and k = 35
