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.
