Program to Swap Numbers with Bitwise (EXOR) Operators

Here is a c program to swap two numbers. This method of swapping does not use a third (temporary) variable. Instead, swapping is done by bitwise operation. We perform bitwise EXOR operations on the two numbers. The program is as follows:

#include<stdio.h>

void main()

{
int x,y;
x=200;
y=140;
printf("\nBefore swapping x=%d,y=%d",x,y);
x=x^y;
y=x^y;
x=x^y;
printf("\nAfter swapping x=%d y=%d",x,y);
}
