50. Reverse an Array Using Only Pointers

#include <stdio.h>

   int arr_temp[n];
   for (int i = n-1; i >= 0; i--)
   {
      arr_temp[i] = (*(ptr + (n-1-i)));
   }

   for (int i = 0; i<n; i++)
   {
    (*(ptr+i)) = arr_temp[i];

   }



   
}

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

    int arr[100];
    for (int i = 0; i < n; i++) {

    }

    reverse_array(arr, n);

    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if(i < n-1){
            printf(" ");
