Question

Design class Person with private fields name and social security number, and a public virtual member Design class Person with private fields name and social security number, and a public virtual member function print().

Derive classes Employee and Student from Person. An employee has a private field salary and a student has a private field grade in addition to the data fields in person.
Derive classes Professor and Secretary from Employee. A professor has a private field research area and a secretary has a private field department he/she works for in addition to the data fields in employee.

Every class has to have a print() function to print its own data fields and those of its base class.

Make sure the following main() function works correctly with your classes.

main()
{
    vector<Person *> persons;

    persons.push_back(new Person("Dave"));
    persons.push_back(new Person("Jack", "123-45-6789"));
    persons.push_back(new Employee("Sam", "111-22-3333", 50'000));
    persons.push_back(new Professor("Kay", "444-33-2222", 70'000, "Parallel Computing"));
    persons.push_back(new Professor("Joy", "555-55-5555", 1'000, "AI"));
    persons.push_back(new Secretary("Misty", "999-99-9999", 900'000));
    persons.push_back(new Student("Ace Prog", "654-32-3456", "B"));

    for (int i = 0; i < persons.size(); i++)
        persons[i]->print();

    for (int i = 0; i < persons.size(); i++)
        delete persons[i];
}

Hand in a printout of your program and typescript of its compile and run.
