Re: [Laurent_R] Hopelessly stuck on an assignment

Thank you guys for your input about better practices. For this program, the final product must look just like this:

Code
Qty       Desc.       Unit $    Total 
2 Hamburger 3.49 6.98
1 Large Coke 1.79 1.79
-------------------------------------------------
Total 8.77

I think I am most puzzled about the "quantity" array I have to use. This program is actually an advanced version of an earlier one. In that one, I had a variable called $tally that would simply add the total up each time the user added an item. Now I tried to figure out a way to tally up the total after a user selects items and the quantity they want... and it also has to be formatted with printf to look just right :(

I looked at the instructions again - apparently, I can get away with not using the @quantity array in such a tricky manner. I'll just have it add one each time the user selects the given item. That'll make things a bit more manageable. Still doesn't totally resolve the printf formatting, though.
