C++20 The Complete Guide

All the new language and library features of C++20 (for those who know the previous versions of C++).

C++20 is the next evolution in modern C++ programming, now supported by major C++ compilers. However, C++20 is huge. It will change the way we program more dramatically than C++11 did. Combining new features gives you even more power. However, not everything is self-explanatory and there are hidden traps. Therefore, it is key to understand all the concepts of C++20 and learn how to benefit best.

This book covers the motivation for and context of all new C++20 features (covering both language and library), providing many examples and unique background information for application programmers as well as for library developers. The focus is on how these features impact day-to-day programming, what effect combining features can have, and how you can benefit from them in practice.

“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 is I am actually afraid of.“

(Leor Zolman)

“I have used some C++20 features before, and now I have a much better big-picture understanding.“

(William Gordon Rutherdale)

“I use this book as a reference almost everyday.”

(Selvakumar Jawahar)
