Please write a code that will perform the below:

Define a class Student with member variables for a student$$s name, student number, address and degree. All of these member variables are strings. Add appropriate constructors

and accessors for class Student and include the following member functions:

$$ a member function display$\_$info$()$that overloads the stream insertion operator $<<$

to display the values of all the member variables of a student.

$$ a member function calcFee$()$ to calculate the initial registration fee for a student.

For undergraduate students the initial registration fee is R$500$ and for postgraduate students the initial registration fee is R$600.$ All undergraduate student degrees begin

with a $$B$$ which will allow you to determine whether a student is an undergraduate or

postgraduate student.

$($a$)$ Implement class Student.

$($b$)$ Test class Student in a driver program that does the following:

$$ instantiates an object of class Student, with the following details:name: Mary Mbeli

student number: $12345678$

address: Po Box $16,$ Pretoria, $0818$

degree: BSc

$$ use the accessor functions to display the specifications of the instantiated object

on the console

$$ display the specifications of the instantiated object on the console with the

member function display$\_$info$().$

$$ calculate and display the fee for the student.

$($c$)$ Derive and implement a class PostgradStd from class Student. This class has an

additional member variable, dissertation $($the title of the Masters of doctorate the

student is doing$).$ Class PostgradStd also has an overloaded constructor and an

accessor member to return the member variable dissertation. The class

PostgradStd should override function display$\_$info$()$ in order to display the

values of all the member variables of PostgradStd. The class PostgradStd should

also override function calcFee$()$ to determine the additional fee for a postgraduate

student which is R$12000.$

Implement the overloaded constructor for the class PostgradStd by invoking the

base class constructor.

$($d$)$ Test class PostgradStd in a driver program that does the following:

$$ instantiates an object of class PostgradStd, with the following

details: name: Mary Mbeli

student number: $12345678$

address: Po Box $16,$ Pretoria, $0818$

degree: PhD

dissertation: How to get a PhD

$$ use the accessor functions to display the specifications of the instantiated object

on the console

$$ display the specifications of the instantiated object on the console with the

member function display$\_$info$().$

calculate and display the outstanding fee for the student
