Help in C++

class Person { // this is the base class private: string name; int idNumber; public: void print(); string getName(); };

class Student : public Person { // this class inherits from the base class Person private: string major; int gradYear; public: void print(); void changeMajor(const string& newMajor); }; void Person::print() { cout

Person person("Mary", 12345); // declare a Person Student student("Bob", 98764, "Math", 2018); // declare a Student cout

Person* pp[100]; // array of 100 Person pointers pp[0] = new Person(); // declare a Person pp[1] = new Student(); // declare a Student cout getName() print(); // invokes Person.print() pp[1]->print(); // also invokes Person.print() pp[1]->changeMajor("Physics"); // ERROR!

virtual void Person::print() { // ... } virtual void Student::print() { // ... }

Person* pp[100]; // array of 100 Person pointers pp[0] = new Person(); // declare a Person pp[1] = new Student(); // declare a Student pp[0]->print(); // invokes Person.print() pp[1]->print(); // invokes Student.print()

I have included the person-student class which needs to be modified. Please comment code and write in C++.

2. Programming exercise. Generalize the Person-Student class hierarchy to include classes Faculty, UndergraduateStudent, GraduateStudent, Professor, Instructor. Clearly show the inheritance structure of these classes. Propose some appropriate member variables for each class. (20 pts.)
