AQA AS Computing Skeleton Code 2014

Hi Guys.

Not sure if this has been uploaded before but I found this excel spreadsheet. If anyone is struggling with Hamming Code take a look.

Seemed useful to me(and of course the AQA AS book) :smile:

Have fun!

Haha same, I keep starting off adding the probability sub first so that it makes it more fun :P

How have you programmed the probabilities? i made an array of probabilities at the start of the game that i increase or decrease depending on the cards drawn..What about you?

Are you sure about 51 ? I replaced all the 52 but it seemed to work fine, what happens when you replace all the 51 as well?

From my understanding you need to replace that because it's under the assumption the deck is 52 cards large. However it isn't there are 13 extra cards that aren't accounted for. Therefore if you don't replace a 51 it would be operating under the assumption the deck is 52 cards big.
So whatever said function does will only work up to the 52nd card in which then it will break.

For instance when updating recent scores if you get to the end of a deck and gameover never = true it passes 51 as a score. Saying you got a score of 51, when you would actually have a higher score since the deck is larger.

A more crucial example:

Sub GetCard(ByRef ThisCard As TCard, ByRef Deck() As TCard, ByVal NoOfCardsTurnedOver As Integer)
Dim Count As Integer
ThisCard = Deck(1)
For Count = 1 To (51 - NoOfCardsTurnedOver)
Deck(Count) = Deck(Count + 1)
Next
Deck(52 - NoOfCardsTurnedOver).Suit = 0
Deck(52 - NoOfCardsTurnedOver).Rank = 0

End Sub

This function would only get cards up to the 52nd position, setting cards after that equal to zero rank and zero suit.

I made a separate procedure, then in that procedure I calculated the percentage of the next card being higher and then call the procedure in the PlayGame procedure

Oh cool I know what you mean

Yep, I'm using VB. So the deck is shuffled. Now what you do is you write each part to a text file using streamwriter, line by line, and then you can use the existing LoadDeck function to load it back.

Aww I'm so confused, do you have the code

can someone post the actual skeleton programs for the following : 2014, 13, 12, 11

Why is every one doing visualbasics, my class started doing that then our teacher told us java is better so we have been using java ever since but its harder so any one here doing java language for comp1?

Anyone know where to find 2012 and 2013 Skeleton code? Preferably pascal but it doesn't matter

Any reason as to why your are using a text file? wouldn't it me much easier to write the whole Array of Deck to a binary file? then read it as it was?

VB is much easier in the sense its for dummies. If you do a mistake it literally tells you how to fix it. Cant go wrong with that if you know what your doing...

The EAD was available from the same place as the skeleton program. You don't actually need it before the exam.
When you turn up for the exam tomorrow, the EAD and a new version of the skeleton program should be set up for you with a new secure network account.

They are completely different programs so I'm not sure how they will help.

hey guys I'm having some trouble with the probability function :s-smilie:

it outputs 0% after each session and I dont know why...
Heres my procedure for it
void SetPercentAge(TCard[] deck, TCard lastCard){
int percentage=(13-lastCard.rank)/13*100;
console.println("Chance of next card being higher = "+percentage+"%");
}

I call it just below the getCard method within the while loop in the play game procedure

while (noOfCardsTurnedOver < 52 && !gameOver) {
getCard(nextCard, deck, noOfCardsTurnedOver);
SetPercentge(deck,lastCard)
}

EAD has a table of some sort iirc? I think it may be a truth table.

Also, are issues such as these good to revise:

Loading / Saving from file
If same card rank, judges by suit
Altering top scores, so only shows if scores are present

Anymore that you would recommend going over a few more times?

Question: "Allow user to save the whole game, including the current player pack and the recent scores, quit the program, then restart program and continue to play saved game/scores."
Is such a question possible or too advanced/unlikely?

Ranking recent scores is pretty essential too, I think that will come up, its really easy once u get the hang of it and I'm pretty sure its gonna be a worth a nifty amount of marks :biggrin:
