50. Reverse an Array Using Only Pointers

#include <stdio.h>

    // Your logic here
        int c = n;
    for(int i=0; i<(n/2); ++i)

        int temp = *ptr;
        *ptr = *(ptr+c-1-i);
        *(ptr+c-1-i) = temp;
        //printf("%d ",*(ptr));
        ptr++;
        c--;
    }
}

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]);
