unique_ptr RAII Basics

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

int main() {
    int N;
    cin >> N;

    {   //ths establishes scope for unique_ptr

        unique_ptr<int[]> data(new int[N]);

        for (int i = 0; i < N; i++) {
            cin >> data[i];
        }

        for (int i = 0; i < N; i++) {
            cout << data[i];
            if (i != N - 1) cout << " ";
        }
        cout << endl;
    }

    cout << "Scope ended" << endl;
    return 0;
}
