Child process, iteration: 3
Parent process, iteration: 3
Child process, iteration: 4
Parent process, iteration: 4
Child process, iteration: 5
Parent process, iteration: 5
Child process, iteration: 6
Parent process, iteration: 6
Child process, iteration: 7
Parent process, iteration: 7
Child process, iteration: 8
Parent process, iteration: 8
Child process, iteration: 9
Parent process, iteration: 9

Please use the attached example file, and change it accordingly.
