All you want to know about c++20!
by Oleksandr Koval
From the article:
The story behind this article is very simple, I wanted to learn about new C++20 language features and to have a brief summary for all of them on a single page. So, I decided to read all proposals and create this “cheat sheet” that explains and demonstrates each feature. This is not a “best practices” kind of article, it serves only demonstrational purpose. Most examples were inspired or directly taken from corresponding proposals, all credit goes to their authors and to members of ISO C++ committee for their work. Enjoy!
