Answer to Question #288904 in C++ for Habiba

Question

Define a Person class containing Name, Age and Id as attributes and constructor, parameterized

constructor, setters, getters, display as member functions.Student – containing program and cgpa as data-members and constructor, parameterized

constructor and setters, getters and display as over-ridden functions Course – containing title, creditHours and prerequisite as data members. Constructor,

parameterized constructor, setters, getters, and display as member function. Relate this class

with Student class (student is registered into a course).

In main( ), create a pointer of the Person class and use it to create different types of persons

(staff, student and faculty). If the Person is a student and is registered in a course, display

function must display all the details of that student.
