Pure virtual functions are functions that must be implemented in the derived class. C++ itself does not have an 'interface' or 'abstract' keyword like other languages, so a looser way to create an abstract class (or interface) is through pure virtual functions. I'll show you an example of how I have used interfaaes in the past in this lesson. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel!
