The Observer Design Pattern in C++ - Part 1 of n - A simple implementation

Показать описание

►Lesson Description: In this lesson I present to you the basics of the Observer Design pattern in C++ with the theory and a first implementation. We will implement the most naive version of the observer pattern so that you understand from scratch exactly how to create this pattern. I'm going to do this in an object oriented manner, but it need not be limited to just object oriented programming.

00:00 Introduction
01:00 Theory of where to use Observer Pattern
10:20 Implementation of Observer Concrete Class
12:30 Implementation of Subject Concrete Class
16:30 Creating a simple test

Observer is a usefull pattern for example web dev in Angular used it, every time action happen in object doom is updated. Patterns is the next level I recommend the Book Design Pattern. Thank you for this great video, I will follow it to learn more 💪🙏.

Can you make a video of Data Oriented Design??

Does that the same as the pattern "pub/sub" and "event emitter"? Sounds so

U have made it very easy to understand, thanks ~Mike();

Thanks man. When's the next part coming?

Do you also intend to present "higher order" (compound) design patterns (like MVC)?

And you can spare yourself a few key strokes by not writing `return 0;` in `main` ( it is not mandated by the C++ standard) 😜

Very good channel on cpp tuts. Are you planning on making the adapter pattern video as well?
