In this Object-Oriented Programming course, I'm explaining the relationship and purpose of virtual functions, pure virtual functions, and abstract classes.
C++ Virtual functions are functions defined in the base class and redefined in the derived class, whose main purpose is achieving runtime-polymorphism. Virtual functions are defined with the "virtual" keyword in the base class. You can find a detailed explanation and an example in this video, and I'll also show you how the runtime polymorphism achieved by using virtual functions looks like.
Pure virtual functions in C++ (abstract function) in C++ is a virtual function for which we don't write implementation in the base class, but we only declare it. In order to declare a pure virtual function, you need to assign 0 in the declaration
Abstract class in C++ is a class that has at least one pure virtual function. The classes which inherit the abstract class must provide a definition for the pure virtual functions, otherwise, they would be abstract themselves and you wouldn't be able to instantiate them.
The main purpose of an abstract class is to provide an appropriate base class from which other classes can inherit.

Thank you for teaching the world C++ in logical, bite-size chunks! I am a longtime C programmer and am just getting up to speed on C++. Your course is helping me do that with minimum effort. I was prompted to leave a comment because I too played the accordion when I was young and I too miss playing it!

I must say, I'm so glad I found this video. I was having a really hard time understanding the concept of virtual functions for months. This demotivated me and caused me to take a long break from learning C++. However, after watching YOUR explanation of it, I actually understand the concept now and the purpose of using it. I've had more confidence in learning the language since then. Thanks!

Thanks for sharing the accordion link with the Just Duet channel. It was very amusing to hear the "Super Mario Bros" and "Still Dre" songs. I chuckled a bit seeing how straight their faces looked as they played. I hope you'll continue with your passion in playing the accordion, it sounds like a wonderful instrument meant for a wonderful person.
