C/C++ Cheatsheet
====================
.. image:: https://img.shields.io/badge/doc-pdf-blue
:target: https://cppcheatsheet.readthedocs.io/_/downloads/en/latest/pdf/
This cheatsheet provides a curated collection of C and C++ code snippets covering modern language standards, system programming, and development tools. From basic syntax to advanced features like coroutines, templates, and memory management, each example is designed to be clear, practical, and ready to use. All code is tested and compiles cleanly, so you can focus on learning and adapting rather than debugging reference material.
/cpp Skill
==========
This repository includes a comprehensive Claude Code skill that automatically provides C/C++ cheat sheet examples when you ask programming questions.
**Installation:**
.. code:: bash
# Install globally for Claude Code
mkdir -p ~/.claude/skills
cp -r skills ~/.claude/skills/cpp
# +The skill covers everything from basic syntax to advanced topics like
# GPU programming, system programming, debugging and so on.
