Nicolai M. Josuttis - C++17 - The Complete Guide

This book is an experiment in two ways:

• I am writing an in-depth book covering language features without the direct help of a core language expert as a co-author. However, I can ask questions and I do.
• I am publishing the book myself on Leanpub and for printing on demand. That is, this book was written step by step and I will publish new versions as soon there is a significant improvement that makes the publication of a new version worthwhile.

The good thing is:

• You get the view of the language features from an experienced application programmersomebody who feels the pain a feature might cause and asks the relevant questions to be able to motivate and explain the design and its consequences for programming in practice.
• You can benefit from my experience with C++17 while I am still learning and writing.

However, you are also part of the experiment.So help me out:give about flaws, errors,features that are not explained well, or gapsso that we all can benefit from these improvements.

First of all I would like to thank you, the C++ community,for making this book possible.The incredible design of new features, thehelpful feedback, and the curiosity are thebasis for the evolution of a successful language.In particular, thanks for all the issues youtold me about and explained and for the feedback you gave.
