need help with struct and class

ka7xx (2)
I wrote the program to the specifications: one struct that is then supposed to be inherited by two seperate classes. However I'm not sure where to go from here.
Im able to use struct person to initialize values in the main however I cannot initialize student without the program crashing.

Im using Bloodshed DEV C++.

Replace the Bloodshed with Orwell: http://en.wikipedia.org/wiki/Dev-C%2B%2B
That way you'll have access to a much more modern compiler, that should be able to be more verbose about various issues.

Please, explain the line 32.

Using Orwell, I made a little more head way. I still feel like I'm going about this in a clumsy manner. I also removed line 32 in the original code.

The question Im searching for is how in my main function do initialize a person who is a student and a person who is an employee ?
