If you prefer extracting raw files manually from the marketplace catalog:

Go to the VS Code Marketplace.
Search for “C/C++” (developed by Microsoft).
In the right-hand sidebar under the “Resources” section, locate and click the “Download Extension” link.
Save the resulting .vsix file to your local computer (e.g., in your Downloads folder).

3. Manual Installation in Visual Studio Code

Once you have successfully downloaded the VSIX package, installing it into VS Code is simple. You can choose between the Graphical User Interface (GUI) or the Command Line Interface (CLI).

Method A: Using the VS Code GUI

Launch Visual Studio Code.
Open the Extensions view (press Ctrl+Shift+X on Windows, or Cmd+Shift+X on macOS).
Click the “…” (Views and More Actions) button at the top-right corner of the Extensions view.
Select “Install from VSIX…” from the dropdown menu.
In the file dialog, navigate to your downloaded C/C++ .vsix file, select it, and click “Install”.

Method B: Using the VS Code CLI

If you prefer working in the terminal or need to automate installation across multiple machines, you can use the command-line utility. Ensure that the code executable is added to your system PATH, then execute the following command:

code --install-extension /path/to/ms-vscode.cpptools-win32-x64.vsix
