Here is an example of a class that takes user input. This class uses the
CashRegister class and simulates a transaction in which a user purchases an item,
pays for it, and receives change.

We call this class CashRegisterSimulator , not CashRegisterTester . We
reserve the Tester suffix for classes whose sole purpose is to test other classes.
