48. Pointer- Swap Value

#include <stdio.h>

void swap(int *p1, int *p2) {
    // Your logic here
    *p1 = (*p1)^(*p2);
    *p2 = (*p1)^(*p2);
    *p1 = (*p1)^(*p2);
}

int main() {
    int a, b;
    scanf("%d %d", &a, &b);

    swap(&a, &b);

    printf("a = %d ", a);
    printf("b = %d", b);

    return 0;
}
