    int arr[10] = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50};

    int sum = 0;

    // Calculate sum
    for (int i = 0; i < 10; i++) {
        sum += arr[i];
    }

    // Calculate average
    double average = (double)sum / 10;

    // Print results
    cout << "Sum of elements: " << sum << endl;
    cout << "Average of elements: " << average << endl;

    return 0;
}
