This is a question from C++ Programming From Problem Analysis To Program Design 7th Edition by D.S Malik.

Define a class Doctor that is derived from class Employee. Add properties specific to the class Doctor. For example, a Doctor record has the doctors specialty (such as pediatrician, Obstetrician, General practitioner, etc., so use type string) and office visit fee (use type double). Be sure your class has a reasonable complement of constructors, accessor, and mutator member functions, an overloaded print function. Write a driver program to test all your functions.

Please Give complete code that works in visual studio.
