Pointer- Swap Value

Code

#include <stdio.h>

void swap(int *p1, int *p2) {
    // Your logic here
    int temp;
    temp = *p1;   // store value at address p1
    *p1 = *p2;     // put value at address p2 into address p1
    *p2 = temp;   // put temp into address p2
}


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

    swap(&a, &b);

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

    return 0;
}
