Derived Classes

You can extend almost any class you want. So once you’ve defined a base class, you just need to know enough about it, and how you want to derive from it. Considering our GenericGeometric class from before, let’s look at deriving a Circle class from it. In our header file we will have: Notice two…

Base vs Derived Classes

One of the cool things about object oriented programming is that you can derive a class from an existing class. this allows you to have most of the class built from an existing class, and not need to rewrite the whole class, only the new parts. Additionally, if the original class, called the base class…
