Behavioral Design Patterns in C++ - Change Manager - II

The video tutorial explains the implementation of a sensor notification system using a change manager. It begins by introducing a base sensor class with virtual functions and discusses the need for a change manager to manage the mapping between subjects and observers. The tutorial then details modifications to the sensor and observer classes, emphasizing the flexibility and reduced dependencies achieved through the change manager. The main function is updated to register subjects and observers with the change manager, and a new subject measuring wind speed is added. The tutorial concludes with a class diagram illustrating the system's architecture and highlights the benefits of using a change manager as a mediator.
