Easy Polymorphism Q Part 2 :)

[TimC]

Ref Polymorphism:

I am trying to get the method calculate_pay() to work. As each type of doctor will have a differnt payrate I am trying to call the calculate_pay() but i am having difficulty. Should it be

int doctor::calculate_pay()
{
return (doctor::get_Payrate()*hours);
}

will this line return each type of doctors payrate multiplied by hours or will it only call the doctor payrate??? or am i way off track

#include <iostream>
#include <stdlib.h>
#include <string.h>
