C program to swap the two numbers using bitwise XOR operation

 /*    Write a c program to swap the contents of two numbers using bitwise XOR operation. Don't use either the temporary variable or arithmetic operators            */

 #include <stdio.h>

 void main()
 {
long i,k;

printf("Enter two integers\n");
scanf("%ld %ld",&i,&k);


printf("\nBefore swapping i= %ld and k = %ld",i,k);

i = i^k;
k = i^k;
i = i^k;

printf("\nAfter swapping i= %ld and k = %ld",i,k);

/*------------------------------------------
Output
Enter two integers
23 34

Before swapping i= 23 and k = 34
After swapping i= 34 and k = 23
