book: rebrand from C++11/14/17/20 to C++11 to C++26

changkun · changkun · commit be2d4913194f · 2026-06-07T18:38:53.000+02:00
The book now covers through C++26, so update the branding everywhere it
was frozen at C++11/14/17/20: both READMEs, the site title/subtitle,
both toc.md headers, both prefaces, the appendix 1 intros, and the
compiler-support link labels.

 The C++ programming language owns a fairly large user group. From the advent of C++98 to the official finalization of C++11, it has continued to stay relevant. C++14/17 is an important complement and optimization for C++11, and C++20 brings this language to the door of modernization. The extended features of all these new standards are integrated into the C++ language and infuse it with new vitality.
 C++ programmers who are still using **traditional C++** (this book refers to C++98 and its previous standards as traditional C++) may even amazed by the fact that they are not using the same language while reading modern C++ code.
 
-**Modern C++** (this book refers to C++11/14/17/20) introduces many features into traditional C++ which bring the entire language to a new level of modernization. Modern C++ not only enhances the usability of the C++ language itself, but the modification of the `auto` keyword semantics gives us more confidence in manipulating extremely complex template types. At the same time, a lot of enhancements have been made to the language runtime. The emergence of Lambda expressions has given C++ the "closure" feature of "anonymous functions", which are  in almost all modern programming languages ​​(such as Python, Swift, etc). It has become commonplace, and the emergence of rvalue references has solved the problem of temporary object efficiency that C++ has long been criticized for.

 First of all, congratulations 🎉 on reading this book! I hope this book has raised your interest in modern C++.
 
-As mentioned in the introduction to this book, this book is just a book that takes you quickly to the new features of modern C++ 11/14/17/20, rather than the advanced learning practice of C++ "Black Magic". The author of course also thinks about this demand, but the content is very difficult and there are few audiences. Here, the author lists some materials that can help you learn more about modern C++ based on this book. I hope I can help you:

 C++ 是一个用户群体相当大的语言。从 C++98 的出现到 C++11 的正式定稿经历了长达十年多之久的积累。C++14/17 则是作为对 C++11 的重要补充和优化，C++20 则将这门语言领进了现代化的大门，所有这些新标准中扩充的特性，给 C++ 这门语言注入了新的活力。
 那些还在坚持使用**传统 C++** （本书把 C++98 及其之前的 C++ 特性均称之为传统 C++）而未接触过现代 C++ 的 C++ 程序员在见到诸如 Lambda 表达式这类全新特性时，甚至会流露出『学的不是同一门语言』的惊叹之情。

 C++17 则是近三年依赖 C++ 社区一致推进的方向，也指出了 **现代C++** 编程的一个重要发展方向。尽管它的出现并不如 C++11 的分量之重，但它包含了大量小而美的语言与特性（例如结构化绑定），这些特性的出现再一次修正了我们在 C++ 中的编程范式。
