Extra information for Exam 1:

You will be asked to write two short programs. In one program, you will instantiate an array of objects of a predefined type, and call one or more methods of each object. In the second program, you will write the code to overload two of the built-in operators for objects of a class. Make sure you know and understand the "formulas" for overloading operators!
