In order for a derived class to call all of the appropriate destructors in the inheritance hierarchy, the base class destructors must be marked as virtual. This ensures that proper RAII practices are being used, and that resources are properly freed in each of the base classes from the derived class. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel!
