Behavioral Design Patterns in C++ - Lamp - II (Enum States)

The video tutorial discusses managing the state of a lamp using different methods, such as integers, booleans, and enums, with a focus on using enums for clarity. It explains how to implement state changes and handle user interactions, like turning the lamp on and off. The tutorial also addresses integrating new features, such as changing the lamp's color, and highlights the challenges of managing complex state changes, suggesting the use of the state design pattern for better management.

Describe the changes needed to integrate a new lamp color feature into the existing lamp class.
