Most nontrivial programs use some form of program loop. Loops are so useful that C# makes several different types available. Now see what loops can do for you.
If you're sitting in a public building right now, look at the ceiling; chances are you can see sprinklers embedded there. In most modern office buildings, each room has one or more sprinklers in it. Modern sprinklers are monitored by software that tests each one to see if it senses a fire.
