can help my in my assignment

[Mooon]

in assignment using inheritance,polymorphism and abstraction in c++.
COLLEGE develops a system in which a user can check the result of concerned modue or subject; this is also used to get the information about the list of student handled by a particular personal tutor.

I have PERSON Class which represents a person by its:ID,firstname,lastname,gender,age,phone,address.

and create 2 class first STUDENT and PERSONAL TUTOR that inherits publicly from class Person,
in student object is distinguished by the same attributes as a Person object which includes the following: Module name, Quiz marks,Test Marks, Assignment marks, Midterm Marks, Finalterm Marks, personal tutor.
All component marks should be calculated out of 100. if student will get less then 40 marks then it should be considered as fail component. by default personal tutor should be NIL. your task is to calculate the marks, average marks,GPA and Result (student should be passed in all components and GP should be greatr than or equal to 4...student must be passed in midterm,final and GP should be greatr than or equal to 10

your system must provide the following to manage the student records.
add student records, delete, update, view all student, show student who gets the max GP, show student who gets the min GP, find student by ID, sort record by ID, show all student who did not assign personal tutor, show all student who assigned personal tutor, show list of passed student, show list of failed student
(save the date in Text file is name person)
