Modern C++ Tutorial: C++11/14/17/20 On the Fly


The book claims to be "On the Fly". Its intent is to provide a comprehensive introduction to the relevant features regarding modern C++ (before 2020s). Readers can choose interesting content according to the following table of content to learn and quickly familiarize the new features you would like to learn. Readers should be aware that not all of these features are required. Instead, it should be learned when you really need it.

At the same time, instead of coding-only, the book introduces the historical background of its technical requirements (as simple as possible), which provides great help in understanding why these features came out.

In addition, the author would like to encourage readers to use modern C++ directly in their new projects and migrate their old projects to modern C++ gradually after reading the book.


  • This book assumes that readers are already familiar with traditional C++ (i.e. C++98 or earlier), or at least that they do not have any difficulty in reading traditional C++ code. In other words, those who have long experience in traditional C++ and people who desire to quickly understand the features of modern C++ in a short period of time are well suited to read the book.

  • This book introduces, to a certain extent, the dark magic of modern C++. However, these magic tricks are very limited, they are not suitable for readers who want to learn advanced C++. The purpose of this book is offering a quick start for modern C++. Of course, advanced readers can also use this book to review and examine themselves on modern C++.
