Josuttis N.M. C++20 The Complete Guide

Leanpub.com, 2022. — 762 p.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.Preface
