Question

C++ Programming.

Create a class hierarchy to be used in a university setting. The classes are as follows:

The base class isPerson. The class should have 3 data members: personID (integer), firstName(string), and lastName(string). The classshould also have a static data member called nextID which is used to assignanID numbertoeach object created(personID). All data members must be private.

Create the following member functions: Accessor functions to allow access to first name and last name (updates and retrieval). These functions should be public. Create a getID function to retrieve the personID of the person. This function should be public. The user oftheclassor any derived class should not have the ability to update personID. Create a constructor with two arguments(first name and last name) with default values.

Create a public member function Print to display information stored in the object. Make this class an abstract class. Create theStudent class as a derived class from the Person class. This class should have two additional data members to keep track of astudent’s GPA (float) and admission term (string –eg. Fall 2019). Create public accessor functions to allow access to the GPA and admission term. The setGPA function should return true if the value of the GPA is between 0 and 4.0(inclusive) and false otherwise. Set the GPA to zero if an invalid value is provided. Override the function Print to print the student information. Create a constructor that takes in four argumentswith default values(first name, last name, admission term, and GPA). Create the Faculty class as a derived class from the Person class. This class should have one additional data member to keep track of the yearthe faculty was hired(string –eg. 2019 ) Create a public accessor functionto allowaccess to the hire year. Override the function Print to print the faculty information. Create a constructor that takes in three argumentswith default values(first name, last name, hire year).

After defining the classes in this hierarchy, write a program that creates objects of each class and tests their member functions. Make sure you include the preprocessor directives (#ifndef, #define, #endif) to prevent a header file from being included (#include) multiple times. Separate the class interface from the class implementation.

Output Sample:

Faculty First Name: John

Faculty Last Name:Smith

Faculty ID:5

Faculty Hire Year:2019

******************************************************

******************************************************

Student First Name: Sarah

Student Last Name: Smith

Student ID: 3

Student GPA: 3.75

Student Admit Term: Fall 2019

Answer 1

CODE:

//Tester program for Person, Student and Faculty classes
//main.cpp
#include<iostream>
//include Student and Faculty header files
#include "Student.h"
#include "Faculty.h"
using namespace std;

int main()
{
   //Create Student and faculty class objects
   Student std("John","Smith",3.75,"Spring 2019");
   Faculty faculty("Mary","Smith","2019");


   cout<<"*******************************************\n";
   //calling Print method on faculty
   faculty.Print();
   cout<<"*******************************************\n";
   cout<<"\n\n\n";
   cout<<"*******************************************\n";
   //calling Print method on Student object
   std.Print();
   cout<<"*******************************************\n";
   return 0;
