All the new language and library features of C++17 (for those who know the previous versions of C++). C++17 is the next evolution in modern C++ programming, now supported by major c++ compilers g++, clang, and Visual C++. Although adopting C++17 it is not as big a step as adopting C++11, C++17 does contain a large number of valuable language and library features, which support and change the way we program in C++. As usual, not everything is self-explanatory, combining new features gives you even more power, and there are hidden traps.The book covers the motivation for and context of all new C++17 features (covering both language and library) with many examples and unique background information for application programmers as well as 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. "It's very clearly written, and the examples are really helpful!" (Graham Markall) "I am thoroughly enjoying the book; I had skimmed the list of changes in C++17 several times before but until I started reading this book, I had no idea how substantial the changes really were. It makes me wonder what I overlooked with previous updates!" (Jason Birch) "I thought I knew a bit about C++. I downloaded this book and learned something new in the preface. Highly recommended so far!"
