Behavioral Design Patterns in C++ - Pros and cons-Memento

The video tutorial explains the Memento design pattern, which is used to manage an object's state without exposing its internal details. The pattern involves three main components: the Originator, which holds the state; the Memento, which stores the state; and the Caretaker, which manages the Memento. Examples include an Account class for transaction rollback and a Hangman game for state checkpoints. The Memento pattern's advantages include state encapsulation and recovery capabilities, while its disadvantages involve potential high storage costs and access restrictions. The pattern is useful for implementing undo and redo functionalities.
