You will implement and test a small class called statistician, which is similar to some of the small classes in Chapter 2 of the text. iman Purposes: Ensure that you can write a small class that meets a precise specification. Make sure you understand how to write a class that is separated into a header file and an implementation file. Give you experience in using a test program to track down bugs in a class's implementation. On M LEARNING OBJECTIVES When you complete Chapter 2, you will be able to. • specify and design new classes using a pattern of information hiding with private member variables, const member functions, and modification member functions. • write a header file and a separate implementation file for any new class. • create and use namespaces to organize new classes. use your new classes (and at least one STL class) in small test programs. • use the automatic assignment operator and the automatic copy constructor. • identify situations in which member functions and constructors can benefit from using default arguments. • corectly identify and use value parameters, reference parameters, and const reference parameters. • overload certain binary operators and input/output operators for new classes. • identify the need for friend functions of a new class and correctly implement such nonmember functions (which are sometimes overloaded operators). • Uuse STL classes, such as the pair class, in an application program.
