50. Reverse an Array Using Only Pointers

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    // Your logic here
    int *p,i,*q;
    char temp;
    p = q = ptr;
    
    while(*q)
    {
        q++;
    }
    q--;
    while(p<q)
    {
        temp = *p;
        *p=*q;
        *q= temp;
        p++;
        q--;

    }

}

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

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
