Lost with this exercise...

[Dizzy]

I have no idea if I'm on the right track or not, anyone that can help, I would greatly appreciate it.

You don't have to do anything in the destructor; you have no resources to release. So, basically, you're not lost, you just didn't know you had nothing to do.

:( to be honest this class was to be an into to C++, but turned out to be a nightmare. Doing the best I can. Still getting a ridiculous amount of errors.

Some of the errors I am getting are from the code which was supplied by the instructor.
