Behavioral Design Patterns in C++ - Slide Deck - III

The video tutorial covers the creation of a new project without using polling, focusing on the Deck class and its interaction with views. It highlights design challenges related to the Open-Closed and Dependency Inversion principles, proposing a solution by programming to an interface. The tutorial implements a flexible design using a list of views and functions like attach, detach, and notify. The Observer design pattern is introduced to promote loose coupling between the deck and views. The video concludes with a mention of unresolved issues to be discussed in the next lecture.
