Behavioral Design Patterns in C++ - Methods for States - IV

The video tutorial explains how to add a new 'yellow' state to a lamp using a state pattern. It demonstrates the process of building the project to observe file changes, implementing state transitions, and testing the lamp's behavior. The tutorial highlights the minimal changes required with a table-based approach and discusses replacing raw pointers with unique pointers for better memory management. It concludes with a summary of the state pattern implementation, emphasizing the benefits of using functions for state-related behavior.
