    int arr[N];
    long long sum = 0;

    std::cout << "Enter 10 integers:\n";
    for (int i = 0; i < N; ++i) {
        // Basic input check: ensures the user enters a valid number
        if (!(std::cin >> arr[i])) {
            std::cerr << "Invalid input\n";
            return 1;
        }
        sum += arr[i];
    }

    std::cout << "Sum = " << sum << '\n';
