My book C++20 is a tutorial and a reference for the C++20 standard. It teaches you C++20 and provides details of this new, thrilling C++ standard. The exciting 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 and 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 to infinite data streams.
• Thanks to coroutines, asynchronous programming in C++ has become 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 obsolete as the preprocessor. Ultimately, we have faster built time and an easier way to build packages.

If you’ve ever asked “what’s in C++17 and what does it mean for me and my code?” — and I hope you have — then this book is for you.

C++11 was a major update for the language. With all the modern features like lambdas, constexpr, variadic templates, threading, range-based for loops, smart pointers and many more powerful elements, it was enormous progress for the language. Even now, in 2018, lots of teams struggle to modernise their projects to leverage all the modern features. Later there was a minor update - C++14, which improved some things from the previous standard and added a few smaller elements. With C++17 we got a lot of mixed emotions.

Although C++17 is not as big as C++11, it's larger than C++14. Everyone expected modules, co-routines, concepts and other powerful features, but it wasn't possible to prepare everything on time.

Is C++17 weak?

Far from it! And this book will show you why!

I spent hundreds of hours investigating how the new things work in order to make a nice and practical book for you. The book will not only save your time but also will guide you through all the nuances of the language.

The book brings you exclusive content about C++17 and draws from the experience of many articles that have appeared on bfilipek.com (and cppstories.com). The chapters were rewritten from the ground-up and updated with the latest information. All of that equipped with lots of new examples and practical tips. Additionally, the book provides insight into the current implementation status, compiler support, performance issues and other relevant knowledge to boost your current projects.

If you have experience with C++11/14 and you want to move forward into the latest C++ standard, then this book is for you.

Here are the features you'll learn:

Part One: C++17 Language features

• Fixes and deprecation
• Language clarification
• General language features
• Templates
• Attributes

Part Two: C++17 The Standard Library
