C++20 : The Complete Guide

This version was published on 2022-10-30

C++20 is the next evolution in modern C++ programming, which will be supported step-by-step by the latest version of gcc, clang, and Visual C++.

C++20 is a big step, maybe even larger than C++11.

It contains a couple of new key features (modules, concepts, ranges, corountines) plus several small but valuable language and library features, which will change the way we program in C++. As usual, not everything is self-explanatory, combining new features gives even more power, and there are hidden traps.

This book presents all the new language and library features of C++20. It covers the motivation and context of each new feature with examples and background information. The focus is on how these features impact day-to-day programming, what it means to combine them, and how to benefit from C++20 in practice.

Testimonials:

"C++20 scared me for a few years, and I am a C++ educator. After reading Nico's fantastic new book, I may still be afraid of C++20, but at least now I have a much deeper understanding of what it actually is I am afraid of." Leor Zolman

"I use this book as reference almost everyday." Selvakumar Jawahar
