In theC++17 Quick Syntax Reference, you will find short, simple, and focused code examples. This book includes a well laid out table of contents and a comprehensive index allowing for easy review. You won't find any technical jargon, bloated samples, drawn out history lessons, or witty stories in this book. What you will find is a language reference that is concise, to the point and highly accessible. The book is packed with useful information and is a must-have for any C++ programmer.
What You'll Learn
Use template argument deduction for class templates


Declare non-type template parameters with auto-folding expressions and auto deduction from braced-init-list


Apply lambdas and lambda capture by value


Work with inline variables, nested namespaces, structured bindings, and selection statements with initializer


Use utf-8 character literals


Carry out direct-list initialization of enums


Use these new C++17 library features or class templates from std:: variant, optional, any, string_view, invoke, apply and more


Do splicing for maps and sets, also new to C++17



Who This Book Is For
Experienced C++ programmers. Additionally, this is a concise, easily-digested introduction for other programmers new to C++.
