Behavioral Design Patterns in C++ - Hangman - V

The lecture discusses an improved design for a game state structure, focusing on making attributes private and using a friend class to control access. It explains the creation of wide and narrow interfaces, the use of private constructors, and exception handling. The Memento design pattern is implemented, with the game state as a nested class of the originator, and the checkpoint manager acting as the caretaker. The lecture concludes with a promise to discuss alternative implementations in the next session.

What is the Memento design pattern and how is it implemented in this context?
