Right now my program is supposed to allow users of repeat the program over again or allow them to restart if they make an error. My code is as follows:



If the user enters "N", the program terminates, but how can I make the program start over again if the user says "Y"? I've been looking for something similar to a GOTO statement (which I know you should NEVER use), and I've found the throw and switch commands. I'm a bit confused to how both of these commands work, and how I could fit them into my program. Any help would be much appreciated!

Use a loop. Something like this would do the trick.
