What is cpp_primer_practice?

This repository is a study companion for the fifth edition of C++ Primer, one of the most widely used textbooks for learning C++. It is written in Chinese and was built collaboratively by multiple contributors. The contents are study notes and exercise answers for each chapter of the book. The repository covers all 19 chapters of the book, organized into four parts: C++ basics (variables, strings, expressions, functions, and classes), the C++ standard library (I/O, containers, algorithms, and memory management), tools for class designers (copy control, operator overloading, and inheritance), and advanced topics (templates, large-scale program tools, and specialized techniques). For each chapter there is a notes file and a separate exercises file. This is not a standalone tutorial. To use it meaningfully, you would need a copy of C++ Primer alongside it. The repository serves as a reference for people working through the book who want to check their answers, read someone else's notes on a tricky section, or fill in gaps from their own reading. The project was developed on Ubuntu using VS Code and the g++ compiler. Two other similar answer repositories for the same book are linked in the README for cross-reference.
