1 COMP1911 Final Exam June 2018 Time allowed: 3 Hours Total number of questions: 8 Total number of marks: 60 Questions are not worth equal marks Answer all questions If you are unwell do not commence this exam - contact an exam supervisor. If you become unwell contact an exam supervisor immediately and ask to speak to the lecturer (Angela Finlayson). Special consideration requests made after doing this exam will be IGNORED. If you need to go to the toilet, ask a supervisor. You are not permitted to bring paper into the exam. There is some space on the attendance sheet for rough work. You are not permitted to retain the attendance sheet. It will be collected by a supervisor. If you need more paper for rough working, put your hand up and ask an attendant. If a problem of any type occurs or if you have a question, report them immediately to an exam supervisor but continue working if possible. You may be given extra time to compensate for any time lost due to computer or other problems beyond your control. To submit your answers for the short answer question (Question 0), just enter your answers in the textboxes and click save. You may submit your answers as often as you like. We mark the most recently saved copy. For the programming questions, (Question 1.. Question 7) answer each question in a SEPARATE file. Each question specifies the name of the file to use. Make sure you use EXACTLY this file name. The exam environment allows you to run a limited set of commands so you can edit, test, debug and submit your answers. The exam environment does not allow access to files in your CSE account or any other CSE account. It does not allow access to the web or other network access. gedit and other editors are available by right-clicking on the desktop and selecting them on the menu. Note: Your gedit preferences are not on this machine. You may wish to change the preferences to your liking once reading time is over.

2 dcc and gcc are available to compile your programs autotest will show you the results of some simple tests. Passing these tests does not guarantee full marks. You also need to do your own testing, especially for the harder questions. You submit programming answers using the give command as described in each question. For example: dcc -o q1 q1.c./q1... autotest 1 q1.c give 1 q1.c You may submit your answers as many times as you like. ONLY your last submission is marked. If you have only a partial solution and the exam is about to end, submit it anyway. In some questions the example executions use particular files. To assist in your testing, copies of these files have been placed in your directory. You have also been given a stub file and a test file for the last question. The command fetch will restore copies of these files if you accidentally remove them. A C reference sheet is available on-line. Manual entries are also available. You will also find a file named template.c in your directory that is a template for a c file. No other documents or files will be available to you. Reminder: You can copy and paste by highlighting text using the left mouse button and clicking with the middle mouse button to paste. The exam environment logs all your actions.

3 Question 0 (9 marks).(a) (1 Mark)....(b) (4 Marks)....(c) (4 Marks)...

4 Question 1 (8 marks) Place your answer to this question in a file named `q1.c` Assumptions Your program must show exactly the same behaviour as the examples shown below. dcc -o q1 q1.c Some simple tests will be run by this command: autotest 1 q1.c Also do your own testing! Submit your answer to this question using the command: give 1 q1.c

5 Question 2 (8 marks) Place your answer to this question in a file named `q2.c` Assumptions Your program must show exactly the same behaviour as the examples shown below. dcc -o q2 q2.c Some simple tests will be run by this command: autotest 2 q2.c Also do your own testing! Submit your answer to this question using the command: give 2 q2.c

6 Question 3 (8 marks) Place your answer to this question in a file named `q3.c` Assumptions... Your program must show exactly the same behaviour as the examples shown below.... dcc -o q3 q3.c Some simple tests will be run by this command: autotest 3 q3.c Also do your own testing! Submit your answer to this question using the command: give 3 q3.c

7 Question 4 (8 marks) Place your answer to this question in a file named `q4.c` Assumptions... Your program must show exactly the same behaviour as the examples shown below.... dcc -o q4 q4.c To compile and run your own tests using the dcc --valgrind flag dcc --valgrind -o q4 q4.c Some simple tests will be run by this command: autotest 4 q4.c Also do your own testing! Submit your answer to this question using the command: give 4 q4.c

8 Question 5 (8 marks) Place your answer to this question in a file named `q5.c` Note: This question is broken down into 3 parts that should all be answered in your `q5.c` file. Assumptions Your program must show exactly the same behaviour as the examples shown below. dcc -o q5 q5.c To compile and run your own tests using the dcc --valgrind flag dcc --valgrind -o q5 q5.c Some simple tests for all 3 stages will be run by this command: autotest 5 q5.c You will submit your answer to this question using the command: give 5 q5.c

9 Question 6 (7 marks) Place your answer to this question in a file named `q6.c`. Note: This question is broken down into 3 parts that should all be answered in your `q6.c` file. You MUST use a struct to appropriately represent. Solutions that do not do this will receive 0 marks. Note: You may use structs to represent other data as well if you wish. To get FULL marks for this question you MUST also break down your program into suitable functions. Otherwise you get a maximum of 4/7..Assumptions dcc -o q6 q6.c To compile and run your own tests using the dcc --valgrind flag dcc --valgrind -o q6 q6.c Some simple tests for all 3 stages will be run by this command: autotest 6 q6.c You will submit your answer to this question using the command: give 6 q6.c

10 Question 7 (4 marks) Place your answer to this question in a file named `q7.c` -- there is already a file called `q7.c` that you should edit. We have provided you with a file named `q7test.c` that contains a simple test case to get you started with your own tests. You may modify this to test your program. You will not submit it. There are also some autotests. Do NOT add a main function to your q7.c file otherwise it will fail the autotests. dcc -o q7 q7.c q7test.c Note: You would then actually run the program as follows./q7 To compile and run your own tests using the dcc --valgrind flag dcc --valgrind -o q7 q7.c q7test.c Some simple tests will be run by this command: autotest 7 q7.c Also do your own testing! Submit your answer to this question using the command: give 7 q7.c
