    C/C++ for Visual Studio Code

    C/C++ for Visual Studio Code

    Repository for the Microsoft C/C++ extension for VS Code

    ...VS Code is first and foremost an editor, and relies on command-line tools to do much of the development workflow. The C/C++ extension does not include a C++ compiler or debugger. You will need to install these tools or use those already installed on your computer. There may already be a C++ compiler and debugger provided by your academic or work development environment. Check with your instructors or colleagues for guidance on installing the recommended C++ toolset (compiler, debugger, project system, linter).
