Complete Modern C++ - Project - Part VI (Virtual Mechanism Walk-through and Virtual Destructor)

The video tutorial explores the implementation and debugging of virtual functions in C++. It covers how the compiler generates code for virtual functions, the role of virtual pointers, and the impact on class size. The tutorial also discusses the invocation of constructors and destructors in a class hierarchy, emphasizing the importance of virtual destructors for correct polymorphic behavior. The video concludes with a demonstration of creating objects on the heap and ensuring proper destructor calls.

How does the invocation of inherited functions work in a derived class?

What is the significance of using a base class pointer to point to derived class objects?

What changes need to be made to ensure proper destructor calls in a class hierarchy?
