The Modern C++ Tutorial repository is a comprehensive educational resource designed to introduce programmers to modern C++ features spanning from C++11 through C++26. Created by Changkun Ou, the project targets developers with existing knowledge of traditional C++ (C++98 or earlier) who want to quickly understand and adopt modern language features without requiring extensive prior experience with newer standards. The repository explicitly positions itself as a quick-start guide rather than an advanced reference, making it suitable for both experienced C++ developers seeking to refresh their knowledge and those transitioning from legacy codebases.
The tutorial distinguishes itself by combining feature documentation with historical context. Rather than presenting features in isolation, the book explains the technical motivations and background behind why each feature was introduced, helping readers understand not just what modern C++ offers but why these additions matter. The author encourages readers to selectively learn features based on actual project needs rather than attempting to master everything at once, acknowledging that not all modern C++ features are required for every use case.
The repository provides multiple consumption formats to accommodate different learning preferences. Readers can access content through GitHub's online interface, PDF documents, EPUB files, or a dedicated website at changkun.de/modern-cpp. The website, built using Hexo and Vue.js, offers mobile-responsive reading alongside the traditional document formats. This multi-format approach reflects consideration for diverse user environments and reading habits.
Practical code examples are central to the learning experience. Each chapter includes substantial code samples organized in a dedicated code directory, with chapters numbered for easy reference. The repository also provides exercises at the end of each chapter with accompanying solutions, enabling readers to test their comprehension of newly learned concepts. This structure supports both passive reading and active learning through hands-on practice.
The project maintains active development and community engagement. GitGenius tracking shows changkun as the primary maintainer with 65 recorded events, while contributors frederick-vs-ja and mobs001 have also participated significantly. The issue and pull request response latency shows a median of 59.4 hours, indicating reasonably responsive maintenance despite the median being skewed by occasional longer delays. Enhancement requests and version 2.0 proposals represent the most common issue categories, suggesting ongoing refinement and planning for expanded content.
The repository's contributor network extends beyond its immediate codebase, with overlapping contributors shared with major projects including llvm/llvm-project, golang/go, and vuejs/vue. This connection to significant open-source projects indicates the tutorial attracts contributors with serious systems programming and language implementation experience.
The codebase is organized for local building using Docker, allowing developers to generate all formats independently. The project operates under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License for written content, while code examples use the MIT license, balancing educational accessibility with appropriate attribution requirements. The repository actively solicits community contributions through its CONTRIBUTING.md guidelines, welcoming corrections, improvements, and translations from readers.
