a- (io pts) Design the class doctorType, inherited from the class Person (that you wrote in Prelab 5 but assume that all strings are not pointers, i.e. string f name; etc) with an additional string data member to store a doctor's specialty. Add appropriate constructors andmember functions to initialize, print, access and manipulate the data members. b- (i0 pts) Design class patientType, inherited from the class Person with additional data members to store a patient's ID, age, date of birth, and attending physician's name (Use the class Date you created in part 1) to store the date of birth. Note that patientType has-a doctorType as a member and doesn't inherit from it. Add appropriate constructors and memberfunctions to initialize access, print, and manipulate the data members. c- (1o pts) Add to class patientType the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital (Use the class Date class) to store admit date, discharge date. Modify constructors nd add memberfunctions to initialize access, and manipulate the new added data members. d- (6 pts) Create a Print () function in Person and override it in both sub-classes Testing your program: (6 pts) In main), create a vector of pointers to type Person. Create three Date objects. One of the dates should be Date di(-1,43,2020). Test your check function to see if it works. Fill the vector up with at least three objects. One of Person, one of doctorType and one of patient Type using the three valid dates you created earlier Print all the data of the three objects of the vector. Make sure each object is printed according to its print function using the overridden Print ( )
