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

The video tutorial discusses the implementation of editor and slideshow views for a slide deck application. Initially, the manual invocation of display functions for each view is highlighted as a challenge, especially with potential future additions of views. The tutorial explores a polling approach to keep views updated, but identifies its inefficiencies, such as unnecessary CPU usage and system resource strain. The video concludes by introducing the observer design pattern as a more efficient solution for automatically updating views when changes occur in the slide deck.

What are the drawbacks of using polling for view updates?

Discuss the potential for users to add or remove views at runtime.

What is the observer design pattern and how can it improve the application?
