damn... there doesn't really seem to be one good report on a sdd teacher at all on these threads

yeh seriously, SamD rocks for goin outta his way to help other students like in marking algorithms and answering questions.

dont think ieee is in the syllabus off the top of my head. although i could be wrong

Hi mattyb, yeh I'll have to completley agree with you on all your posts in this topic so far. I also have been programming for several years now.. and no not in html or vb but in more challenging languages like PHP (favourite ^^), MySQL (yeh i know its not relly language), CGI, ASP yeh theres a...

It's not for the option topic its the common topic. Translation comprises of Lexical analysis Syntactic anaylsis Type checking Conversion

haha Josh man whats up. Go0d luck f0r tom0rrow buddy!

For algorithms, I'm sure that your "i" variable should be 0 as the first element in the array is identified by a 0 but yours is good. I dont think it matters how you start actually. Personally, i like using index= 0 array_length = get the length of desired array WHILE index <...

Ok. But what about the whole lexical and syntactical analysis? First formatting is discarded and then the elements of the resultant code are converted to tokens. The tokens are parsed into a parse tree before being traversed. Traversing is where each indiviual token is then finally converted to...

8/10 :( so far the lowest I guess. I'll argue that I think 10 was A. I base this on that the Uniting Church was created in 1973 due mainly to the reason that the white Australia policy was removed in 1958 and dismantled in 1973 and was therefore in response to the growing concern of the...

Thankyou Sam (talk about a quick reply). I want to thankyou again for this method, It's amazing how quick/easy it is.

Courtesy of Freedom_Dragon everyone. Here is the example response for question 25: http://resma.net/q25_b56_s3.pdf

This method is excellent. I have seriously never seen this method before.. Stupid question time though: would this be valid to use in the HSC? because by dividing by base you aren't really showing that you have knowledge that hex is taken by dividing the binary bit into two nibbles of 4 bits...

Sorry -X-.. my bad. Shoulda read your post properly. Sorry my fault :)

Couldn't you just convert the second element to a ones or twos complement then add the two numbers together? I'm using the logic: x - y = x + (-y) where -y is simply the ones complement or twos complement.

I based my post of this quote "samples of responses typically produced by students whose achievements place them on the borderline between two bands."Source It did not say "gained full marks"

You're supposed to choose yourself. For that question I am guessing off the top of my head its the train one? Well if it is, then you'd obviously choose a linear storyboard as you wouldn't want the user to go directly to the thankyou page if they haven't bought a ticket as the possibility in a...

They haven't asked yet for string processing as such but what they have asked is to do this algorithm and one of the criteria was that it sorted a record by the ticket number. Without sounding too cliche' here I will have to say that if it's in the syllabus, the BOS has the power to test it...

No no, its for the option topic "Software Developers view of hardware" in the sub-section "binary arithmetic". If you're doing the other option of evolution of programming languages (assuming it has no dot point covering binary arithmetic) you should be fine.

To explain why we divide by 2 you need to get a grasp on two's complement. Just using a broken down component (4bit instead of 5) In 1's complement with 3bits of data to store 000 = 0 001 = 1 010 = 2 011 = 3 100 = 4 101 = 5 110 = 6 111 = 7 Applying 1's complement (meaning that a...

Damn SamD beat me to it! Well the answer is actually in the excel book on page 293 and as SamD said, you just draw rectangles to represent the adders. Why? Becasue you are looking at it from the black box perspective (output/input) so no processing is important at this stage. and also check...
