Until you press any key, it blocks the screen. How to compile and run the C++ programThere are 2 ways to compile and run the C++ program, by menu and by shortcut. By menu Now click on the compile menu then compile sub menu to compile the c++ program. Then click on the run menu then run sub menu to run the c++ program. By shortcut Or, press ctrl+f9 keys compile and run the program directly. You will see the following output on user screen. You can view the user screen any time by pressing the alt+f5 keys.
