you have been given a task to develop a program in C++ that will take marks of different assessments as input and displays total marks as output

The Virtual University of Pakistan is an institute that offers technical and non-technical courses based on the distance learning model where one can join any of the courses just by using a computer system. Consider that you are enrolled in a course, OOP (Object Oriented Programming), and you have been given a task to develop a program in C++ that will take marks of different assessments as input and displays total marks as output.

Step by step instructions: 

• Write a C++ class name Student with the following attribute: Student Id, Student name, quiz marks (for 4 quizzes), assignment marks (for 2 assignments), Mid Term Marks, Final Term Marks, Total Marks 
• Write a parameterized constructor which passes all the data members of the Student class? 
• Write an appropriate copy constructor for the student class 
• Write member functions for the following requirements: 

Function Name	Description
enterData()	To input data from the user through the console as mentioned in the screenshot.
calculateResult()	To calculate the result according to the grading scheme.
displayData()	To print data on the screen as mentioned in the screenshot.

Grading scheme:

Activity	Weightage	Number of activities	Formulation
Quiz	10%	4	Obtained Marks in all quizzes / Total Marks in all quizzes * 10
Assignment	20%	2	Obtained Marks in all Assignments/ Total Marks in all Assignments * 10
Mid Term Exam	30%	1	Obtained Marks in all Mid Term/ Total Marks in all Mid Term                       * 10
Final Term Exam	40%	1	Obtained Marks in all Final Term / Total Marks in all Final Term                      * 10

Perform the following tasks in main(): 

• Create an array of size 3 Student objects using the new operator
• Initialize the index [0] using parameterized constructor 
• Enter data for the index [1] through enterData() 
• Copy index[1] object into index [2] by using copy constructor 
• Display all the Records by using displayData()
