C Program to Swap Two Numbers without using Third Variable

#include<stdio.h>
#include<conio.h>
int main()
{
    int a,b;
    //clrscr();
    printf("Enter the Values of a and b : ");
    scanf("%d %d",&a,&b);
    printf("Actual values : \n a=%d \t b=%d",a,b);
    a=a^b;
    b=a^b;
    a=b^a;
    printf("\n After Swapping : \n a=%d \t b=%d",a,b);
    return 0;
}

 OUTPUT:

Enter the Values of a and b : 5 7
Actual values :
 a=5     b=7
 After Swapping :
 a=7     b=5
