Behavioral Design Patterns in C++ - Hangman - III

The video tutorial discusses adding a feature to the Hangman game that allows users to revert to an earlier state using checkpoints. It explains the implementation of a game state structure to manage the state of the Hangman object and how to store and restore these states using a vector. The tutorial also highlights the importance of saving checkpoints before modifying the game state and provides an example of restoring a game state after a player loses. Finally, it addresses design issues, such as the violation of the single responsibility principle, and suggests separating responsibilities into different classes using the Memento design pattern.
