Question

In my code there is a problem where even when I enter ‘Q’ or ‘q’ the program keeps looping the menu. What’s wrong here? Here is the code:

{
    char selection;
    do {
        cout << "Add a county election file         A" << endl;
        cout << "Show election totals on screen     P" << endl;
        cout << "Search for county results          S" << endl;
        cout << "Exit the program                   Q" << endl;
        cout << "Please enter your choice: ";
        cin >> selection;
    } while ((selection != 'Q' || selection != 'q'));
    return 0;
}

Answer 1

You want to use the And (&&) operator in your test, not the Or (||) operator. Otherwise, one of selection != 'Q' and selection != 'q' will always be true, and your loop will never exit.
