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

The video tutorial discusses the Chain of Responsibility pattern, focusing on handling requests that may fall off the chain if not properly managed. It highlights the importance of ensuring requests are handled appropriately, even when no specific handler is available. The tutorial introduces the concept of a default logger to manage unhandled requests and suggests implementing a null logger as the last node in the chain for better design flexibility. The video concludes with a brief wrap-up and a look ahead to the next lecture.

What happens when a request cannot be handled by any logger in the chain?

Why is it important to ensure that a request does not fall off the chain?

How does the implementation of a default logger differ from a console logger?

What is the role of the null logger in the logging chain?

What changes are proposed to improve the design of the logging mechanism?
