About the Book

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}

Buy early, pay less, free updates

Note that this book is published step-by-step. The first public version was published in June 2021. Since then, the contents grows with new chapters, examples, and caveats about the features of C++20 and I integrate all feedback I get for the pages already published.

The book is feature complete now.

Just minore details and copy editing is missing.

See cppstd20.com for a detailed list of all the topics covered.

As written, once you bought the ebook you will get all updates for free.

PDF versus Other Formats

I write the book in LaTeX and generate PDF from it (the way I wrote my other books). The other formats (epub, mobi, and online reading) come from the leanpub markdown interface, for which I generate the necessary input from LaTeX by script.

Thus, the PDF layout has a better quality than the other formats. For example, the syntax highlighting rules for the formats other than PDF have to get fixed as soon as possible and the index is missing yet. Leanpub and me are working on corresponding improvements.

I hope you enjoy and benefit.
