new[] must be paired with delete[].

Solution explanation

Manual new/delete is error-prone; modern C++ uses vector or smart pointers instead.

Show solution

#include <iostream>
using namespace std;

int main() {
    int n;
    cin >> n;
    int *a = new int[n];
    for (int i = 0; i < n; i++) cin >> a[i];
    for (int i = n - 1; i >= 0; i--) cout << a[i] << (i > 0 ? " " : "\n");
    delete[] a;
    return 0;
}
