  array<int, 5> arr{10, 20, 30, 40, 50};

  cout << "element at index 0: " << get<0>(arr) << endl;
  cout << "element at index 1: " << get<1>(arr) << endl;
  cout << "element at index 2: " << get<2>(arr) << endl;
  cout << "element at index 3: " << get<3>(arr) << endl;
  cout << "element at index 4: " << get<4>(arr) << endl;

  return 0;
