Once your executable is ready after the build, you can execute it by clicking on the Execute button in the extended toolbar, choosing the menu item BuildExecute, or pressing F3. Unlike the build stage, execution doesn't check for dependencies (at least for the time being). In other words, it does not check if the executable is up-to-date before it executes the program. So, you must take care of that yourself. If you want to pass any arguments to your program, choose Build Set Program params …, enter the arguments in the dialog that appears (shown below) and click OK. You can also specify whether the program should be run in a terminal or not.
