Lesson 16 - Abstract classes and interfaces in C++

In the previous lesson, Polymorphism in C++, we finished our arena. We won't work with it in other C++ tutorials, but we'll create new projects. Since we are getting to the more advanced topics, it's not possible to write a fully-featured app (or part of it) in every lesson. This is because the constructs we're going to introduce require some code basis and also because the topics won't be that related as before and forcing the next lessons to be demonstrated on a single project would be at least complicated. So, we'll only demonstrate some constructs on small examples to clarify the syntax. At this point you should have enough experience to come up with your own situations where this techniques can come in handy. Of course, I'll continue to try to give you real use cases as well.

Now we can start with a new topic. This time it'll be abstract methods and classes.
