In Chris Pine's book, "Learn to Program", he asks you to write a small
app. I'm having trouble writing this app and I was wondering if anyone
could help me out.

Here's the excerpt:

"I guess we could write a program which asks for your first, middle,
and last names individually, and then adds those lengths together...
hey, why don't you do that! Go ahead, I'll wait."

I'm having a problem writing this code. I know a lot of you will look
at this and think this is the easiest thing ever. I hope I catch
someone like that to help me out.

Any ideas?

thanks a lot.
