Hints

Store the numbers in a vector first.

Loop from index n - 1 down to 0.

Solution explanation

You can't print backwards until you've read everything, so the vector stores the numbers first.

Show solution

#include <iostream>
#include <vector>
using namespace std;

int main() {
    int n;
    cin >> n;
    vector<int> v(n);
    for (int i = 0; i < n; i++) {
        cin >> v[i];
    }
    for (int i = n - 1; i >= 0; i--) {
        cout << v[i];
        if (i > 0) cout << " ";
    }
    cout << "\n";
    return 0;
}
