Question
Give the definition of a class named Doctor whose objects are records for a clinic’s doctors. This class will be a derived class of the class SalariedEmployee given in Display 14.4. A Doctor record has the doctor’s 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 and accessor methods, an overloaded assignment operator, and a copy constructor. Write a driver program to test all your methods.
Answer

NOTE: Please refer the textbook for salariedemployee.h, salariedemployee.cpp, employee.h, and employee.cpp files.
