Conditions in class member functions

tywin (5)
Hello, if someone could aid in my project that would be wonderful. I have the core program down, it runs fine and whatnot. However, my conditions inside my class member functions do not operate whatesoever.

Example, if cin >> vehicleID doesn't satisfy my condition (must be only three digits)it should proceed to ask for the vehicleID until it is three digits.

Thank you for your time and concern,

A number cannot be both (less than 99) AND (greater than 1000).

Hope this helps.

Wow, VERY silly error!
Thank you so much.. I need to be more observant I guess.
Simple replace with || :)

Have a great night
