SWAP TWO NUMBERS USING BITWISE (XOR)

Consider the following I/O samples.

SAMPLE INPUT : 8000  200

SAMPLE OUTPUT:  200 8000

C PROGRAM:

#include <stdio.h>
int main()
{
    int a,b,t;
    scanf("%d %d",&a,&b);
    printf("\nBefore swapping : A = %d B = %d",a,b);

    a^=b;

             b^=a;

             a^=b; 

    printf("\nAfter swapping : A = %d B = %d",a,b);
    return 0;

}

 

OUTPUT:

 

  

The given source code in C program is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
