48. Pointer- Swap Value

#include <stdio.h>

void swap(int *p1, int *p2) {
    // Your logic here

    /*int* ptr;
    *ptr=p1;
    p1=p2;
    p2=*ptr;/*
    */
    int temp=*p1;//store the value of p1;
    *p1=*p2;
    *p2=temp;


}

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

    swap(&a, &b);

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

    return 0;
