Project Overview¶

1. Introduction¶

Chinese name: C++那些事
English name: Stories About C Plus Plus or CPlusPlusThings

C++那些事 is an open-source learning project aimed at both C++ beginners and intermediate developers. It is designed to help learners progress from the basics of C++ to advanced topics, covering everything from syntax fundamentals, object-oriented programming, template programming, and STL usage to multithreading and concurrency, memory management, and performance optimization. In addition, the project takes a deep dive into the source code of several classic open-source libraries and frameworks, helping developers better understand how C++ is applied in real-world projects.

2. Goals¶

From beginner to advanced: provides beginners with a systematic learning path that takes them step by step from zero to mastering the core concepts and advanced features of C++.
Interview preparation: offers analysis and hands-on practice for common C++ interview questions, helping candidates stand out in interviews.
Source code analysis: by analyzing the source code of classic open-source projects, it helps developers gain a deep understanding of C++ design patterns and implementation principles.
Multithreading and concurrency: takes an in-depth look at multithreaded programming and concurrency control in C++, helping developers write efficient, safe concurrent programs.
Performance optimization: introduces performance optimization techniques in C++, helping developers write efficient code.

3. Content¶

The C++那些事 project is rich in content and covers every aspect of C++, organized into the following major modules:

Fundamentals to Advanced
- Keywords and features: detailed explanations of keywords such as const, static, this, inline, sizeof, virtual, volatile, explicit, friend, using, ::, enum, and decltype.
- Functions and pointers: function pointers, pure virtual functions and abstract classes, vptr_vtable, and more.
- Data structures: struct, union, bit fields, the difference between references and pointers, and more.
- Implementing C++ polymorphism in C: implementing the polymorphism features of C++ in the C language.
- Macros and assertions: defining and using macros, and typical use cases for assert.
Hands-on series
- 10-day crash practice: rapidly level up your C++ programming skills through ten days of intensive exercises.
- Key hands-on exercises: targeted practice on the key and difficult points of C++ to consolidate what you have learned.
STL source code analysis
- Containers: source code analysis of containers such as array, deque, queue, stack, list, vector, rb_tree, set, multiset, map, multimap, hashtable, and unordered_map.
- Iterators and traits: iterator, traits, typename, and more.
- EBO optimization: the Empty Base Optimization (EBO) technique used in STL design.
C++2.0 new features
- C++11 features: automatic type deduction, lambda expressions, rvalue references, smart pointers, and more; see also the C++11 topic on this site.
- C++17 / C++20: the C++17 topic and the C++20 topic.
Extended topics
- Deep dives into language mechanisms: mutable, the whole const family, ABI, tail recursion, and more (see the navigation item "Fundamentals to Advanced → Deep dives into language mechanisms").
- Memory and debugging, benchmarks, hands-on projects, reading and tips: standalone navigation sections with practical articles on AddressSanitizer, Benchmark, pybind11, gRPC, and more.
Design patterns
- Common design patterns: how classic patterns such as Singleton, Factory, and Observer are applied in C++.
Concurrent programming
- Multithreading and multiprocessing: multithreaded programming techniques such as std::thread, std::async, std::mutex, and std::condition_variable.
- C++ Concurrency in Action: an in-depth exploration of concurrency models and practice in C++.
C++ idioms
- Programming style and idioms: explores common C++ programming styles and idioms, helping developers write more elegant code.
Courses
- GeekTime's "Modern C++ in Practice: 30 Lectures": a recommended learning resource for systematically studying modern C++.
Tools
- Debugging and printing tools: how to use debugging tools such as dbg-macro and rr.
- Container printing helpers: tools that make printing containers more convenient.
- Watching the compiler at work: observing how C++ code changes through the compilation process with the help of tools.

4. Highlights¶

Systematic learning path: content progresses step by step from fundamentals to advanced topics, suitable for learners at different levels.
Theory combined with practice: in addition to theoretical explanations, there is an abundance of code examples and hands-on projects.
In-depth source code analysis: by analyzing the source code of classic open-source projects, it helps developers deeply understand the design and implementation of C++.
Multithreading and concurrency: an in-depth discussion of concurrent programming in C++, helping developers write efficient, safe concurrent programs.
Interview oriented: provides analysis of common interview questions, helping candidates prepare better for interviews.

5. Resources¶

Online learning site: C++那些事
WeChat official account: 光城
Bilibili videos: 未来的光城 — the project's content is also published on Bilibili in video form, making it convenient for learners to watch.

6. How to Contribute¶

7. Roadmap¶

More advanced topics: such as C++20 features, metaprogramming, and compile-time computation.
More hands-on projects: more hands-on projects to help developers apply what they have learned in real-world development.
Community building: building a more active community and encouraging developers to exchange ideas and share.

8. Final Words¶

C++那些事 is an open-source project dedicated to helping C++ learners go from beginner to advanced. Whether you are a beginner or a developer with some experience, you can find learning resources that suit you here. We hope that through this project, more people will master C++ and use it with confidence in real-world development.
