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.

What changes need to be made to the lamp when adding a new yellow state?

Explain the process of transitioning the lamp from yellow state to off state.

How does the table-based approach minimize changes when adding a new state?

What is the significance of using a unique pointer instead of a raw pointer in this implementation?

Describe the steps required to implement the destructor for the LAMP class.
