Behavioral Design Patterns in C++ - Hangman - IV

The video tutorial discusses the implementation of the Memento design pattern in a Hangman game to adhere to the single responsibility principle. It explains how to create and manage checkpoints using a checkpoint manager, separating responsibilities into different classes for better design. The tutorial covers the creation of functions for checkpoint management and the implementation of a caretaker class to handle these checkpoints, ultimately improving the game's design and functionality.

What methods are required in the caretaker class for managing checkpoints?

How does the implementation ensure that checkpoints can be restored?

What improvements does the new design offer compared to the earlier implementation?
