8. Write a macro that swaps two numbers. WAP to use it.

 #include <stdio.h>

#define SWAP(x, y) (x ^= y ^= x ^= y)

int main()

{

    int num1, num2;

    

    printf("Enter any two number to swap: ");

    scanf("%d%d", &num1, &num2);

    printf("Values before swapping\n");

    printf("num1 = %d, num2 = %d\n\n", num1, num2);

    SWAP(num1, num2);

    printf("Values after swapping\n");

    printf("num1 = %d, num2 = %d\n", num1, num2);

    return 0;

}
