Help w/Structs and 'For' loops

[KittyGirl]

OK, here's my problem. This is supposed to print out a list of menu items. You choose from the list, then print the bill. My problem is that I can't seem to get the menu items to print out in a tabular format and my printout won't add the items together. I keep getting zeros for the tax and amount due. Any help is greatly appreciated.

Thanks!

OK, I finally got it to print out in the tabular format, but I still can't get it to add the amounts. I've tried a few different things, but I think my for loop may be wrong. Can someone help, please?

Thanks!

Well, I got the 'for' statement correct, but it still isn't printing a list of choices or adding the amounts. Should I put an 'if' statement in there? Please advise. This is due tonight.

Thanks!

Here's the most recent code that I've done.

Never mind. I finally figured it out.
