That is exactly what that snippet of code does.

As for the rest of it, nuh uh, that isn't how it works. This is a place for people to learn about programming, not a place for people to get their projects done by others. If I think that I can give you a little help and you can try the rest, I may donate a little effort. If you want to demand a detailed spec and show no evidence of putting any of your own effort in, that sounds like real work. I'm perfectly willing to discuss my hourly rate with you, but I won't contribute anything more for free.
