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.

What is the purpose of the attach and detach functions in the Deck class?

How does the Deck class notify the views when data is modified?

What issues remain to be resolved after implementing the Observer design pattern?
