C++ overridden virtual function not getting called [duplicate]

Answer 1

I am agree with "It'sPete". because you haven't used the GuidedTour class. It will work if you use the following method.

int main()
{
  vector  tourList;
  Tour* tour_ptr;

  for (unsigned int i = 0; i < tourList.size(); i++)
  {
      tour_ptr = &tourList[i];
      tour_ptr->display();
  }
}
