                            This can be done with a boolean return type for this function (returns true until they choose to logout, then it returns false)
                            Or with a separate function like Andrew did in Teacher (you can check his code for a template).
                            The idea is that as much of the process of each menu is contained within the menu function, (ecapsulation). */
