1. Introduction
The purpose of this tutorial letter is to supply the solution for Assignment 2, and to indicate how you should
interpret the results you obtained for this assignment. This assignment covers the work discussed in
Chapters 10, 11 and 12 of the Study Guide (Tutorial Letter 102), as well as the relevant sections in
Chapters 10, 11 and 12, and Appendices 7 and 8 of Savitch. Note that you should have included the input

The assessment and feedback given on your assignment, serve as an indication of your mastering of the

3. Allocation of marks
When we mark assignments, we comment on your answers. Many students make the same mistakes and
consequently we discuss general problems in the tutorial letters. It is, therefore, important to work through
the tutorial letters and to make sure you understand our solutions and where you went wrong.

The maximum number of marks you could obtain for Assignment 2 is 55. This is converted to a
percentage. If you for instance obtained 30 marks for Assignment 2, you received 55% for Assignment
2. This percentage in turn contributes a weight of 80% to the year mark, as can be seen in the
summary of the weights allocated to the assignments for COS1512 below.

Assignment Weight
number
1 20
2 80
3 0

Questions 2, 4 and 6 have not been marked. However, 5 marks are awarded if you attempted questions 2,
4 and 6. Please note that this is NOT the way exam answers will be marked. In the exam you will
receive marks for specific statements as indicated by the exam question. The purpose of the assignments
is to provide you with an opportunity to practice the concepts you are studying. Your marks for the
assignment is an indication of whether or not you could implement those concepts. We include complete
solutions for all questions.

The marks you received for question 1 were determined on the following basis:
Question not done 0/5
Question attempted, but the program does not work at all 1/5
A good attempt, but there are a few problems with your answer 3/5
The program works correctly and produces the correct output 5/5

The marks you received for question 3 are indicated by ticks (√) in the solution.

The marks you received for questions 5 and 7 was determined on the following basis:
Question not done 0/15
Question attempted, but the program does not work at all 5/15
A good attempt, but there are a few problems with your answer 10/15
The program works correctly and produces the correct output 15/15

In other words, you can obtain a maximum of 5 marks for questions 1, 2, 3, 4 and 6; and a maximum of 15
marks for questions 5 and 7.

Note that not all mistakes are corrected – but we will provide informative comments.

If you did not include the program output for questions 1, it means there are “a few problems with your
answer” and the maximum you can get is then 3/5. If you did not include the program output for questions
5 and 7, it means there are “a few problems with your answer” and the maximum you can get is then 10/15.

We did not award any marks to assignments submitted more than four weeks after the due date.
However, we still provided informative comments.
