Web Editor Explained

The window to the left is editable - edit the code and click on the "Run" button to view the result in the right window.

The Dropdown list to the right of the "Run" button allows you to change programming languages.

By selecting the "input" tab, you can add user input to use in the code.

The "+" tabs allows you to add additional files (for the same language you are currently running) to run.
