Behavioral Design Patterns in C++ - Lamp - III (State Pattern)

The lecture covers modifying the LAMP implementation using the state pattern instead of enums. It involves creating state classes to manage behavior, handling state transitions, and ensuring proper memory management. The advantages of this approach over switch cases are discussed, along with generating a class diagram. The lecture concludes with a preview of adding more states in the next session.

What is the purpose of creating a base class called 'State' in the implementation?

Describe the role of the 'setstate' function in the context of the lamp's state management.

What changes are made to the LAMP class to accommodate the new state pattern?

Explain how the state classes provide behavior for the lamp based on its current state.

What advantages does the state pattern offer over the previous implementation using switch cases?

How does the implementation of the destructor in the state class contribute to memory management?

What is the significance of deleting old state objects in the LAMP class?
