Hey, Andrew. Good catch on the 12:59 boundary. I was thinking backwards on that, <br><br>You're right. A deadline time of 12:59 means an overstay at 13:00.<br><br>Well done. Two doggie biscuits for you. Redeemable at McKinnon SC from 12:01 to 12:03 a.m. on any night with a blue moon.<br>

Thanks to Mark for his insightful commentary on the exam - a much needed lightening of the day - and to everyone else who contributed.<br>
<br>
I have a different take on two algorithm questions:<br>
<br>
Qn C7:<br>
If currentTime=1300, then deadlineTime of 1259 will incur a fine, as they have past the time of the deadline.<br>
<br>
So my table is:<br>
<br>
dlTime Exp outcome Line Reason<br>
1300 none #7 curTime is = not > dlTime<br>
1259 Msg #7 curTime IS > dlTime<br>
1301 none #7 curTime is < not > dlTime<br>
-1 none #6 existence check/no car<br>
<br>
And Qn C9<br>
I think there are actually TWO errors in the algorithm.<br>
The line length(numberplate) < 6 should be <= 6 or < 7 [so is a RANGE CHECK error]<br>
AND<br>
The line For position <- 1 To length(numberPlate) does not work for zero-based arrays. Aren't they all unless specified?<br>
So should be For position <- 0 To Length<numberplate) - 1 [so is OFF BY ONE error]<br>
<br>
In Q11 is it true in a complied program that variable names are replaced by memory addresses at runtime so reducing variable name length would not actually improve performance anyway?<br>
It might reduce compile time, but...There is no indication whether Kirsten will make an "app" ie compiled or web-app therefore interpreted?<br>
<br>
Finally are the following questions really worth the marks they have attributed?<br>
C4: Answer: Response rates - reason, the system is trying to overcome time limits and folks driving off before being nabbed.<br>
Is that worth 1+ 3 marks?<br>
C6a: Answer must be sorted.<br>
2 marks? Or do you have to specify ascending order?<br>
<br>
