few errors I need resolved

fwhale (3)
Hi all,

Creating a code and compiling in g++ that works as an inventory program. Pretty simple stuff.

I'm getting a few errors/warnings that sound like simple errors but I need a fresh set of eyes to take a look. For both functions below I get this: "error: a function-definition is not allowed here before '{' token. I also get a warning and an error on the last line of the code. 1. warning: no newline at end of file. 2. error: expected '}' at the end of input.

To me it sounds like i'm just missing a curly brace somewhere, but everything looks like it lines up to me :x

Can anyone tell me what's up?

There is a lot of code missing here. Where is class Inventory?

Well that's not the entire code.... Just put the two functions that were giving me trouble. Here's the entire code:

Line 115 missing a '}'.

That was silly. I updated a few things and put the new code into my previous post. Only compilation errors I get now are that "info" and "item_numbers" aren't within the scope of main. I'm not sure where I should declare these though. I tried some different things, but can't quite get it right.

"info" and "item_numbers" are private fields in the Inventory class. So, what you need to do is to create an object of type Inventory and use the Inventory methods on it. You don't have to deal with the fields at all.
