C++ Token Class Code Problem

I am currently in my second year for Game Software Development and we have been working with code in just about ever semester. I have had some experience with programming in C++ but the code that we have been working with has given me some problems, main because I haven't worked with if before and the "terms" used can just complicate things.

I'm currently working on an assignment with some signifcant code, however, the manner in which it is to be arranged in confuses me. The commented out code is the "Token Class" code given to us but I don't believe that it is correct.
This is my first post and tips/adive is greatly appreciated
