Order Status

Xesna (27)
The DEV C++ tends to stop working when it get to void displayOrder. I'm wondering what I did wrong? I also placed one comment in the code explaining what I am trying to do. It may be the cause behind it or not.

How exactly does it stop working?

It doesn't seem like it should crash, so what do you mean stop working?

//I'm trying to get the negative result, then turn it to positive. 
                 backOrder = stock - ordered * (1-2);


To set your number to a positive, you could use
backOrder = abs(stock - ordered);

I think it's more of the DEV C++ that isn't working properly, but anyway; is there any problem with my coding? No syntax or logical errors? I can't run it while "Windows is looking for a solution."

How do you know its not working?
Also, if you're using the compiler that comes with Dev-C++ from 2005, then it might be the compiler. Otherwise, never doubt the compiler unless it's a real edge case.

I'm running the code every time and the moment it encounters:

The number of spools ready to ship from stock:


It gives me a message that the Order Status has stopped working. Windows is looking for a Solution.

If it's the compiler, can anyone redirect me to acquire a new one. However, if it's not the compiler, then there's a bug in the coding that it can't seem to find.

Previous EDIT: No. It isn't the compiler. I ran my other programming challenges and they worked fine. Thus, ruling out that possibility and leaving with the code.

EDIT: I found the error, it required the use of references and in case anyone who's learning C++ in the future:
