When you enter a 1 from a keyboard, you can see the 1 on the screen. This is because you have entered he character 1 rather then the integer 1. That is, '1' versus 1.

Try case '1': rather than case 1: and see if that helps.

[Frinavale]

Likewise, if you want to do something in the case where the user enters the character 'Q', you need to add that into your code.

Also, the variable that stores the user input will need to be changed to a type that can hold the type of input provided.

If you're wanting to allow alpha-numeric input, then you might try using a std::string or char array for order instead. Your sentinel would need modification though.

A char type would work too, but leaves the little newline gremlin to deal with.
