You're stuck in a party theme :D

It compiled and ran on the first try. I figured I might as well make it a big 
party:

$ partyplan
How many people are you inviting to the party?
567
You'll need 569 plates, so you'll have a few extra.
You'll need 189 gallons of punch.
You'll need 283 bags of chips.
You'll need 567 funny hats so everyone can have one.

I like this, it's all orderly and you use different types of arithmetic in each 
function, which is the kind of thing I like to do for simple demos of 
variations.
