Behavioral Design Patterns in C++ - Logging System - III

The lecture explains the implementation of the chain of responsibility pattern to simplify the Winapp class's logging mechanism. Initially, the Winapp class manages multiple loggers, but this is cumbersome. By introducing a chain of responsibility, the Winapp class only needs to know the head of the logger chain. The lecture details modifications to the logger class, including adding a successor link and setting up a chain of loggers. The chain allows for flexible handling of log requests, with the ability to add new logger types like a console logger. The chain of responsibility pattern enhances flexibility by allowing requests to be handled by multiple handlers without the sender managing them directly.

How does the implementation of the chain of responsibility simplify the logging process in the Winapp class?

Describe how new logger types can be added to the chain of responsibility.

What is the significance of keeping the successor link in the base class of the logger?
