Behavioral Design Patterns in C++ - Help System - I

The video tutorial explains the implementation of the Chain of Responsibility design pattern through a help system example in an application. It describes how the application handles user help requests by sequentially checking Quick Help, Local Help, and Online Help components. If none can provide help, a generic error message is displayed. The video emphasizes the pattern's ability to form a chain of handlers, each passing the request to the next if it cannot handle it.

Explain how the application handles a situation where no help is available from any source.

Identify the three types of help components mentioned in the video and their roles.
