Store code help (parse error[i think])

umbranival (6)
I've been working with this code for an assignment and the first time I tried to compile it my computer got stuck in a loop where the log would just jump from one file to the next in an attempt to compile. Closed, opened again, tried again, this time it threw all kinds of parse errors but I don't quite understand what the problem is.

I got it to compile. You need to fix your client file first. Declare before you use. You need to use prototypes at top before main. Also you should have class declarations in the header and definitions in the .cpp.. and remove your constructors from being commented out.

Thanks for you help! I really do appreciate it! And PLU is product label, its in the text file, supposed to be a sort of barcode number. Will clarify. Onto the random error I'm getting from the receipt program. Thanks again!
