Help with an algorithm.

[viper12]

Here is a simple algorithm that uses a while loop.

set theinitial valueofcount to10
while(NOT(count is 0))
write the valueofcount in theoutput window
decreasecount by 1
move to thenext lineof theoutput window
write 'zero' in theoutput window

Figure 4 An algorithm using a while loop

(a)What will be written to the output window when this algorithm
is run? [2]

(b)Suppose the second line of the algorithm were changed to read
while(count is 11)
What will be written when the modified algorithm is run? [2]



Suppose you are a given a pile of cards, each of which shows one
of the following four shapes: square or circle, shaded or unshaded
(Figure5). You can assume these are the only possibilities.

Write a set of instructions using while loop and if...else
selection structures to sort the pile of cards according to the
symbols they display and write an appropriate message for each
card, for example 'shaded circle' or 'unshaded square'. Each
message should be on a new line.
In your answer you should use indentation to help make the
structure of the algorithm clear.

Please see link for important information regarding your problem.

Actually I was just wondering which format an output would be required in regards to the 2nd question.

Actually I was just wondering which format an output would be required in regards to the 2nd question.

I would assume a nicely arranged textual format.

Hehe. I'll sort that out.

On another note, do you know of any software that executes algorithms in their pure form, since I need to make sure the algorithm for the pile of cards is right.
