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!
