The changkun/modern-cpp-tutorial repository is a comprehensive educational resource designed to introduce and explain the features of modern C++ standards, specifically C++11, C++14, C++17, C++20, and beyond. Authored by Changkun Ou, the tutorial is structured as a book that aims to bridge the gap between traditional C++ (such as C++98) and the newer language standards, making it accessible for experienced C++ programmers as well as those seeking a rapid understanding of modern C++ features.
The primary purpose of the repository is to provide a practical and historical perspective on the evolution of C++. Each chapter not only covers the syntax and usage of new language features but also delves into the rationale behind their introduction, helping readers understand the motivations and technical requirements that shaped modern C++. This approach enables learners to appreciate the context and utility of features such as lambda expressions, smart pointers, concurrency, and template enhancements, among others.
The tutorial is organized for flexible learning. Readers can navigate the content online via the GitHub repository, download PDF or EPUB versions, or access the material through a dedicated website. The book is segmented into chapters, each focusing on specific aspects of modern C++. Every chapter includes numerous code examples, which are also available in the repository, organized by chapter for easy reference. This structure allows readers to experiment with code and reinforce their understanding through hands-on practice.
To further support learning, the repository includes exercises at the end of each chapter. These exercises are designed to test comprehension and mastery of the material, with suggested answers provided in a separate directory. This interactive element encourages active engagement and self-assessment, making the tutorial suitable for both self-study and classroom use.
The repository also contains the source code for the tutorial’s website, which is built using Hexo and Vue.js. The website offers a mobile-friendly interface, providing another convenient way to access the book’s content. For those interested in building the tutorial and website locally, Docker support is provided, simplifying the setup and build process.
The tutorial is primarily targeted at programmers who are already comfortable with traditional C++ and want to quickly learn the new features introduced in modern standards. While it covers some advanced topics and so-called "dark magic" of modern C++, its main focus is on practical, everyday features that can be immediately applied to new projects or used to modernize existing codebases. Advanced readers can use the tutorial as a review or reference guide.
The repository is open to contributions, with guidelines for reporting issues or submitting pull requests. The book itself is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, while the code examples are released under the MIT license, promoting open access and collaboration.
In summary, changkun/modern-cpp-tutorial serves as a valuable resource for C++ programmers seeking to understand and adopt modern C++ features. Its blend of historical context, practical examples, exercises, and flexible access options makes it an effective tool for both learning and reference, supporting the transition to modern C++ in both new and legacy projects.
