Pointer- Swap Value

Code

#include <stdio.h>

void swap(int *p1, int *p2) {
    // Your logic here
    int temp = *p1;      // store the *p1 value in temp
    *p1 = *p2;           // *p2 storing in the *p1
    *p2 = temp;          //  temp value storing in the *p2
}

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

    swap(&a, &b);

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

    return 0;
}

Solving Approach

void swap(int *p1, int *p2) {
    // Your logic here
    int temp = *p1;      // store the *p1 value in temp
    *p1 = *p2;           // *p2 storing in the *p1
    *p2 = temp;          //  temp value storing in the *p2
}
