    // Prompt user for input
    cout << "Marks of A: ";
    cin >> a;
    cout << "\nMarks of B: ";
    cin >> b;
    cout << "\nMarks of C: ";
    cin >> c;
    cout << "\nMarks of D: ";
    cin >> d;

    // Calculate the total
    total = a + b + c + d;

    // Output the result
    cout << "\nTotal is: " << total << endl;

    getch();
