First, this maybe should have posted this in a section of the forum that's for C++ programming. You can still move it by editing the topic.
Second, Class needs to be lowercased. ;)
Third, did you mean ostream& operator << by any chance?
Fourth... we have a policy against giving out full problem solutions, which is kind-of what you're asking us for. Show us what you've done for the implementation so far and ask for help with that or ask for a hint as to where to start, but if you ask us for a full solution... erm... we'll likely say "no".
That said, I'd like to come to the final problem which is that... the class you posted doesn't match the description (Person vs Vehicle or Truck : Vehicle). Oops.
