Behavioral Design Patterns in C++ - Chat System - II

The video tutorial explains the implementation of a chat server using a subclass of a server, called a chat server. It manages participants using an unordered map, allowing direct and broadcast messaging. The server is implemented as a Singleton and uses the observer pattern to manage participant interactions. The tutorial covers participant registration, message sending logic, and simulates communication between participants. It concludes with a discussion on the class diagram, design patterns like observer and mediator, and the benefits of loose coupling.
