C++ 11/14/17 issue is used to track the principle description error,`typo` error, and the questions to the author of the book.

- Usually, you may encounter typos, semantic errors, grammatical errors, and etc. These are all`typo` errors. If an error has caused some obstacles to your reading and you strongly believe that the`typo` will also affect others reading. Then you are very welcome to[submit issue](https://github.com/changkun/modern-cpp-tutorial/issues) to report the`typo` error.

Since this repository provides a variety of reading approaches, thus make sure you have checked all items in the following checklist:

-[ ] If you only making changes to the main part of the book (i.e. the`book` folder), and no changes to the code snippet, then you are good to go;

-[ ] If you alsochange the code snippet in the main body of the book, then you need to synchronize the corresponding code snippet in the`code` folder;

-[ ] Ifyou changes also involve the exercises, you also need to synchronize the contents of the`exercises` folder.

-[ ] If you alsochanged the code snippet in the main body of the book, then you need to synchronize the corresponding code snippet in the`code` folder;

-[ ] Ifyour changes also involve the exercises, you also need to synchronize the contents of the`exercises` folder.

The book claims "On the Fly". Its intent is to provide a comprehensive introduction to the relevant features regarding modern C++ (before 2020s).

The book claimsto 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 aware that all of these features arenotrequired.Itshould beleart when you really need it.

Readers shouldbeaware thatnotall of these features are required.Instead, itshould belearned when you really need it.

At the same time, instead ofgrammar-only, the book introduces the historical backgroundas simple as possibleof its technical requirements, which provides great help in understanding why these featurescomes out.

- This book assumes that readers are already familiar with traditional C++ (i.e. C++98 or earlier), at least 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 ofthe dark magic of modern C++. However, thesemagics 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++.
