ABOUT THIS COURSE

This course is your complete guide to the latest version of C++: C++20. You will run through the flagship features of C++20 but also every minor addition to C++. Initially, you will learn the details of the new standard and most notably, you will focus on the big four: concepts, modules, range library, and coroutines. You will also cover the additions to the standard library and concurrency in detail. To get the information to sink in, each chapter includes tons of example code for you to get a vivid idea about what to expect from each feature. Lastly, you will get into some case studies to apply the theory into practice.

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.
