Answer to Question #207459 in C++ for osama

Question

Create a class named Person, which contains

• A pure virtual function named print()

• Two data fields i.e. personName and age

A class named Student inherits Person class, which contains

• Two data fields i.e. Std_id and Cgpa

• Overridden function print() to display all details relevant to a patient

A class named Regular inherited from class Student which holds

• A data field representing the name of School

• A data filed representing the Fee

• Overridden function print() to display all details relevant to a Regular student

A class named Private inherited from class Student which holds

• A data field representing the address

• A data filed representing the Fee

• Overridden function print() to display all details relevant to a private Student.

In the main function, create instances of derived classes to access respective print() function using dynamic binding.
