Reverse an Array Using Only Pointers

Code

#include <stdio.h>

void reverse_array(int *ptr, int n) {
    if (n==1){
        printf("%d", ptr[n-1]);
    }
    else{
   for(int i=0; i<n;i++){
    printf("%d ", ptr[n-i-1]);
   }
}
}

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);
    return 0;
}
