Question [100 Marks) A school wants to store information about its students joining a mentoring programme that the school currently runs. The students are divided into two groups, mentors and mentees. Mentors are more knowledgeable students and offer helps to mentees. Mentors are chosen from those students with good CPAs. They can mentor only one mentee maximum. Mentee's progress are kept track based on their levels, i.e., from level 1 to 5 where 5 indicates a mastery level. Besides, mentee's contact information will also be stored. Given a class diagaram that models the above problem in Figure 1 and the details about it the class diagram in Table 3. Answer the questions 1 to 3 below. Note: As for questions 1 and 2, write your answers on papers, and for question 3, write your program using any C++ IDE such as DevCpp. Use the codebase program provided, main.cpp. 1. Determine whether the following classes form any relationship to each other in the context of Object-Oriented Programming (OOP). If so, name the type of relationship, otherwise write No Relationship. a. Student and Mentor b. Mentor and Mentee c. Contact and Mentor d. Mentee and Contact e. Contact and Student f Mentee and Student (12 marks) 2. The problem given above involves several OOP concepts including inheritance and polymorphism. a. Explain TWO (2) main roles of the inheritance concept in the above problem. Indicate in which part of the class diagram these roles take place. (16 marks) b. Explain how the concept of polymorphism plays the role in the above problem. (10 marks) c. Identify TWO (2) methods that will be specified as polymorphic. Justify your answer. Finaly, explain how you are going to make these methods polymorphic. (12 marks) 3. Implement the class diagram in Ch. Separate the class definition from the class declaration within the same file. Accomplish the following tasks in your program. Write your code in the provided codebase program. Note that, some of the code has been given in the codebase program. a. Complete the declaration of all classes. (12 marks) b. Define all the methods of the class Student. ( 6 marks) c. Define all the methods of the class Mentee. (5 marks) d. Define all the methods of the class Mentor. (13 marks) e. In the main function, declare two arrays below: an array of mentees an array of mentors and initialize the arrays with the sample data given in Table 1 and Table 2.
