But this is conceptually WRONG, and will cause a linker error on the instructor's test system if he/she actually does provide this definition. You need to find out for sure.

Awesome. That got rid of that error. Only for more to crop up.

THANK YOU! I was looking at that one error for 5 hours. Even though it might be wrong. But yes, we are allowed to modify all the files. Phew.

Just to clarify why I think this is conceptually wrong...

If the instructor is providing a class for you to plug into your code, then he/she should be providing everything. Declaring the static member is inappropriate, because you're just compensating for the incompleteness of an external module that SHOULD have been complete.

Like I said, if the instructor links against some object that DOES provide the definition, your own definition will conflict with it. It's just sloppy, that's all.
