Given a C++ program named program2.cpp that four classes named Course, Teacher and Exercises, respectively. Analyze the program and answer the following questions:

a. Identify the types of relationship between Teacher and Course classes and the relationship between Exercises and Course classes

b. Define the meaning of different type of relationship implemented in object-oriented programming as stated below:

i. Composition

ii. Aggregation

iii. Inheritance c

C. Complete the UML diagram in Figure 2 by drawing the correct notations that match the type of relationship identified in.

d. Afterwards, convert the content in program2.cpp in the same UML diagram drawed for (c) by filling in each class's attributes and methods completely.

e. Differentiate between association, aggregation and composition by giving an example of each of them

Note: As for question (a) until (e), write your answers in the answer_booklet.docx file provided. Alternatively, you may also write answers on papers and take snapshots of them with your smartphone.
