C++ Classes and Class Hierarchy

So far, you have learned how we address most of the objectives outlined for this program. The only objective

left involves the demonstration of some C++ features. In this program we use a class hierarchy with the

inheritance feature. Also, we use polymorphism with dynamic binding and function overloading with static

binding.

First let us look at the class hierarchy used for this program (see Figure 7.2). An abstract class is a class that is

never meant to be instantiated as an object, but serves as a base class from which others can inherit

functionality and interface definitions. The layer class is such a class. You will see shortly that one of its

functions is set = zero, which indicates that this class is an abstract base class. From the layer class are two

branches. One is the input_layer class, and the other is the output_layer class. The middle layer class is very

much like the output layer in function and so inherits from the output_layer class.
