Hello,
What you need to do is write a function into the class. your person will read
and write it's data, mark it as virtual. then from employee you can do
something like: person::read(stream) person::write(stream) etc and then below
that read in and write the data for that specific class. So your building off
the inheritance.
Thanks,
