A school wants to store information about its students joining a mentoring programme that the school currently nuns. 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 CHIDE such as DevCpp. Use the codebase program provided, inain.cpp Student Abbreviations: name Studentin) getName() setName(n) displayinfo) 1: name 1: level e: email p : phone x: expertise m: mentee Mentee Mentor level expertise Menteen. e, p.) displayinfo) Mentorn, x) displayinfo) assignmentee(m) getMentee Contact email phone Contacte,p) displayInfo() getEmail) setEmaille) getPhone) setPhone(p) Figure 1: Class diagram Table 3: Description of the members of each class.

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)
