==================== 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.
Plugin ======
cppcheatsheet is available as a Claude Code plugin. Once installed, Claude automatically uses the cheat sheets to answer C/C++ questions — just ask naturally and the skill triggers based on context.
Installation
------------
As a Claude Code plugin (recommended):
.. code-block:: bash
Step 1: Add the marketplace
claude plugin marketplace add crazyguitar/cppcheatsheet
Step 2: Install the plugin
claude plugin install cppcheatsheet@cppcheatsheet
Local testing (single session only):
.. code-block:: bash
claude --plugin-dir /path/to/cppcheatsheet
Manual installation (requires cloning the repo):
.. code-block:: bash
git clone https://github.com/crazyguitar/cppcheatsheet.git mkdir -p ~/.claude/skills cp -r cppcheatsheet/skills/cpp ~/.claude/skills/cpp
C/C++ Interview Cheatsheet ==========================
Curated C and C++ interview questions indexed by topic — each question links directly to the section of the cheat sheet that answers it. Use it for quick review before an interview, or to drill down on a specific area (RAII, move semantics, templates, concurrency, and more).
