Visual Studio Code
Visual Studio Code is a popular, easy to use code editor. It can be installed from its website. Installers are provided for Windows, OS X and Linux.
Once installed, we recommend adding the C++ plugins to the editor.
Open the extensions panel using Ctrl+Shift+X and enter ms-vscode.cpptools into the extension search field.
This should allow you to find the plugin and install it.

We strongly recommend enabling auto save of files to avoid outdated files during compilation.
