About the Book

My book C++20 is both: a tutorial and reference to the C++20 standard. It teaches you C++20 and provides you with the details of this new thrilling C++ standard. The thrilling factor is mainly due to the big four of C++20.

  • Concepts change the way we think and program templates. They are semantic categories for the template parameters. They enable you to express your intention directly in the type system. If something goes wrong, you get a clear error message.
  • The new ranges library enables it to perform algorithms directly on the container, compose the algorithm with the pipe symbol, and apply them onto infinite data streams.
  • Thanks to coroutines asynchronous programming in C++ becomes mainstream. Coroutines are the base for cooperative tasks, event loops, infinite data streams, or pipelines.
  • Modules overcome the restrictions of header files. They promise a lot. For example, the separation of header and source files becomes as obsolete as the preprocessor. In the end, we have faster built time and an easier way to build packages.

About the Author

Rainer Grimm
Rainer Grimm

I've worked as a software architect, team lead, and instructor since 1999. In 2002, I created a further education round at my company. I have given training courses since 2002. My first tutorials were about proprietary management software, but soon after, I began teaching Python and C++. In my spare time, I like to write articles about C++, Python, and Haskell. I also like to speak at conferences. I publish weekly on my English blog https://www.modernescpp.com and the https://www.grimm-jaud.de/index.php/blog, hosted by Heise Developer.

Since 2016, I have been an independent instructor giving seminars about modern C++ and Python. I have published several books in various languages about modern C++ and in particular, concurrency. Due to my profession, I always search for the best way to teach modern C++.

My books "C++ 11 für Programmierer ", "C++" and "C++ Standardbibliothek kurz & gut" for the "kurz & gut" series were published by Pearson and O'Reilly. They are available in German, English, Korean, and Persian. In summer 2018 I published a new book on Leanpub: "Concurrency with Modern C++". This book is also available in German: "Modernes C++: Concurrency meistern".

'C++ 20: Get the details' is exactly the book you need right now if you want to immerse yourself in the latest version of C++. It's a complete guide, Rainer doesn't only discuss the flagship features of C++20, but also every minor addition to the language. Luckily, the book includes tons of example code, so even if you don't have direct access yet to the latest compilers, you will have a very good idea of what you can expect from the different features. A highly recommended read!

C++ has evolved a lot from its birth. With C++20, it is like a new language now. Surely this book is not a primer to teach you inheritance or overloading, but if you need to bring your C++ knowledge up to date, this is the right book. You will be surprised about the new features C++20 brought into C++. This book gives you clear explanations with concise examples. Its organization allows you to use it as a reference later. It can help you unleash the old language into its powerful future.

    C++20

    Rainer Grimm

    C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.

    The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.
