Calculator apps (e.g. bc, xcalc) are available on your workstation.
During the Exam, you must not
communicate with other students in any way
access any of your own files
access any web pages except those attached to this web site
Answers to all questions are submitted online

for Q2..Q8, type your answer into the file with .txt suffix (e.g. q2.txt)
use the submit command as described at the end of each question
If you believe that insufficient information has been provided to answer
a given question, then you should write any assumptions that you think are
necessary to complete the question and continue work from there. If the
assumptions are reasonable, you can still obtain full marks for the question.
Note that marks are awarded for primarily for working, not just for getting
the correct final answer. If you get an incorrect final answer in one part of
a question and use it in a later part of that question, it is still possible
to achieve full marks for the later part if all working is correct.
For the programming question, you can only receive full marks for a
correctly-working program that compiles with no warnings. In all other
cases, you receive partial-marks based on how close the program
is to being correct. Submitting an unchanged Scan.c is worth zero marks.
