CLion enables running entire applications as well as unit tests.
If you have configured Before launch tools in a Run/Debug configuration, CLion runs them first, and then will run the application. Otherwise, the program will start immediately.
If you are not going to pass any parameters to your program, and your program does not require any specific actions to be performed before start, you can run it right from the editor.
Click in the gutter near the class declaration and select Run.
If you are going to pass parameters to your program or otherwise customize the startup of your program, use a run/debug configuration.
On the main toolbar, select the run/debug configuration you are going to use.
Click or press Shift+F10.
When the application starts, you can view its output in the Run tool window. Every run/debug configuration creates a separate tab when you run it.
To learn more about tool windows and how to manage them, see the Tool windows topic.
On the toolbar of the Run tool window, click or press Shift+F10
Stop and pause applications
When you stop a program, its process is interrupted and exits immediately. When you pause a program, it continues running in the background, but its output is suspended.
Stop a program

Pause a program
Right-click in the Run tool window and select Pause Output from the context menu. Use the same toggle to resume the program.
Show running processes
You can view the list of all active run or debug sessions and navigate between them.
From the main menu, select Run | Show Running List. In the top-right corner of the editor, CLion shows a list with all active applications.
