> Microsoft's official VS Code extension providing IntelliSense, debugging, code browsing, and refactoring for C and C++ projects on any platform.

## Install

Save as a script file and run:

# VS Code C/C++ Extension — IntelliSense and Debugging for C and C++

## Quick Use
```bash
code --install-extension ms-vscode.cpptools
# Open a C/C++ project folder in VS Code
# IntelliSense activates automatically for .c, .cpp, .h files
```

## Introduction
The C/C++ extension by Microsoft brings full-featured IntelliSense, debugging, and code navigation to Visual Studio Code. It transforms VS Code into a capable C and C++ IDE with support for GCC, Clang, and MSVC toolchains across Linux, macOS, and Windows.

## What the C/C++ Extension Does
- Provide context-aware code completion and parameter hints for C/C++
- Enable breakpoint debugging with GDB, LLDB, and the Visual Studio debugger
- Navigate code with Go to Definition, Find All References, and Call Hierarchy
- Display inline diagnostics and compiler errors as you type
- Support CMake, Makefile, and compile_commands.json project configurations

## Architecture Overview
The extension runs a language server process that parses your C/C++ source files and headers using a custom IntelliSense engine. It reads compilation databases or user-configured include paths to resolve symbols accurately. For debugging, it communicates with GDB or LLDB through the Debug Adapter Protocol, providing a graphical debug experience in the VS Code UI.

## Self-Hosting & Configuration
- Install from the VS Code marketplace; works on Linux, macOS, and Windows
- Configure include paths and compiler settings in `c_cpp_properties.json`
- Point to a `compile_commands.json` for accurate project-wide IntelliSense
- Set up launch configurations in `launch.json` for debugging
- Pair with the CMake Tools extension for seamless CMake project integration

## Key Features
- IntelliSense engine provides accurate completions even in large codebases
- Integrated debugging supports conditional breakpoints, watch expressions, and memory inspection
- Code formatting with clang-format integration and configurable styles
- Header/source switching with a single keyboard shortcut
- Remote development support via SSH, containers, and WSL

## Comparison with Similar Tools
- **CLion** — full C++ IDE by JetBrains; VS Code C/C++ is free and lighter weight
- **clangd** — alternative language server; the Microsoft extension offers tighter VS Code integration
- **Eclipse CDT** — Java-based IDE; VS Code provides a faster, more modern editing experience
- **Code::Blocks** — standalone C++ IDE; VS Code offers a larger extension ecosystem

## FAQ
**Q: Which compilers are supported?**
A: GCC, Clang, and MSVC on their respective platforms. The extension auto-detects installed compilers.

**Q: Can I use it with CMake projects?**
A: Yes. Install the CMake Tools extension alongside it for full CMake integration including build, test, and debug.

**Q: How do I fix IntelliSense errors?**
A: Ensure your include paths are correctly configured in `c_cpp_properties.json` or provide a `compile_commands.json` file.

**Q: Does it support C++20 and C++23 features?**
A: Yes. Set the `cppStandard` property in your configuration to enable modern C++ standard support.
