CODE NEEDED IS BELOW:

Question (Inheritance) Derive the class doctor Type, inherited from the class personType, with an additional class member variable member to store a doctor\'s specialty (string type) Then implement following class member function prototypes. doctor Type(string, string, string),llFirstname Lastname Specialty doctor Type0,/Default constructor void set Specialty(string);llSet doctor specialty string getSpecialty0const ll Get doctor specialty void printoconst;/Display doctor information the same as given output format Derive the class patientType, inherited from the class personType, with additional class member variables to store a patient\'s id, age, and dob (all are integers). Then, implement following class member function prototypes. patient Type string, string, int, int, int illFirstname Lastname id age dob patient Type0, Default constructor void setld(int);llSet patient id void setage(int);llSet patient age void set Dob(int), MISet patient DOB int getld0constilGet patient id int getage0constilGet patient int get Doboconst,//Get patient DOB void printoconst, /Display patient information the same as given output format

        string getFirstName()const;
        string getLastName()const;
        personType(string first = \"\", string last = \"\");
        //Constructor
        //Sets firstName and lastName according to the parameters.
        //The default values of the parameters are null strings.
        //Postcondition: firstName = first; lastName = last
private:
        string firstName; //variable to store the first name
        string lastName; //variable to store the last name
};
