Behavioral Design Patterns in C++ - Pros and Cons-Chain Of Responsibility

The video tutorial explains the Chain of Responsibility pattern, which allows a request to be handled by a chain of handlers without the sender needing to know which handler will process it. Examples include a help system and a logging system. The pattern promotes loose coupling and flexibility but requires correct configuration to avoid unhandled requests. It is compared to the Decorator pattern, highlighting differences in behavior addition and request handling. The tutorial concludes with guidelines on when to use the pattern, emphasizing dynamic handler selection and multiple handler scenarios.
