<DIV><FONT size=2 face=Arial>Hi Heath,</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Hope someone else with more recent SOD expertise
can help you.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I would agree that arrays and linked lists can hold
only one data type while records can hold several different data
types.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Linked lists are, as you say, ordered and
sequential while arrays (1, 2 or 3 D) allow random access. Records? All the data
for one record is stored together, the records being stored in order of
entry, and the whole data table may be indexed on any one of the data items
in the record.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>How much more would they want for 6
marks?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Anyway, good luck that your SOD year finishes soon.
I start ITA exam marking with the training session on Friday and then a fairly
hectic week.</FONT></DIV>

<P class=MsoNormal>Heya all,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Some of my students are going through the sample questions
posted back in April 07 on the SD VCAA website. I looked back at the
archives (Apr 07) and found Mark and Gordon’s multi choice answers which I
agreed with but I’m trying to work out what is expected from Question 2 of
section B. <o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>It states: Three simple types of data structure are
arrays, records and linked lists.<o:p></o:p></P>
<P class=MsoNormal>For each of these three data structures, identify the types
of data that they deal with and the way the data is organised. (6
marks)<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Is “types of data” different from “data types”?
<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>My thoughts are linked lists are sequential and ordered
while arrays can have random access, is this organisation?<o:p></o:p></P>
<P class=MsoNormal>An array can only hold one data type while a record can
have several different data types.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I would love some help on this one. <o:p></o:p></P>
<P class=MsoNormal>Three sleeps til I can clear the mess of exam papers off my
desk!<o:p></o:p></P>
<P class=MsoNormal>Cheers! <o:p></o:p></P>
