Computer Studies Notes + Tips + Queries

[Faizan Muhammmad]

And how many marks do usually manage to get?
For me there almost always occur "silly" mistakes.whtever u may describe it . ..Hopefully tht doesn,t happen with us in CIEs

i have to start papers, i was preparing for others before :/

 

[M.Omar]

What as the additional information needed in the internet based system?

Email address it cud have been credit details but since a imilar case in past ppr occurred and no mention of credit card info in MS so I chose email address

 

[DAZ1234]

Number of places left=x
Repeat
Input n
If n>1 and n<10
then x=x-n
Else Output ''Number of people exceed number of vacancies left''
Until x=0
Output ''No more vacancies left anymore''
This is what I wrote. This is correct, right? ._.

Cool, I wrote the same as well
Have you ever seen the IGCSE gts. It is pretty low

IGCSE olevels I don't get wht,s the deal ...any diff?
Perhaps pprs r hard so gt r low.

Yeah
Hey do you know any good language to start programming in?

Yeah Correct but I don't know about the loop I didn't add one.

 

[DAZ1234]

Yeah Correct but I don't know about the loop I didn't add one.

It'll stop when the number of vacancies is zero. So loop made sense.
I'm so smart :''D

 

[DAZ1234]

Yeah. No distinction for me. I didn't aim for it.

Oh shut the front door! CIEs gonna be licking your *** : P

Distinction was like this:

Came, Saw, Gone

Some probs here and there:
firstly 1 and 10 needed to be added...Don't worry shud be no prob on this one...not greater or smaller sign but like this >=
2ndly We shud not define the original number of places as already stored but I get wht u intend tht this basically can be any value so
the first 2 probs r for me still negligible
but here,s what u shud not hav done....
The condition was tht no ppl entered >=1 and <= number of available bookings not 10
Doing this means tht whenever another booking is made by diff customers it will take the value of 10 as condition and not number of ppl
This will cause a prob here:
Suppose after one booking x=8
now inputting n as 9 satisfies ur condition n>1 and n<10 giving x=8-9=-1!

You're right. I should've added "AND n<x" in the code. (I did add equal signs in inequalities, but omitted 'em here)
But since I added "Until x=0", It'll never reach a negative value. Offc it wont show that it ran out of X before booking all the people either :|.
And for the value of x, I read a Q in ATP that said something like "you can assume the value of PRICE to be predefined" or something. And there was no other way to do anything else here :|. Lets hope the examiner doesn't look too deep into this : D

Yeah value x shud not be sth to think abt but abt reaching 0 u wrote tht until X= 0 so if the value jumps btw it then still more probs

Can anyone suggest a book for computer science(2210) o'level (revised syllabus)?

 

[nishni perera]

Can i please know any easy way of remembering the theory parts . Like the fetch execute cycle ..... Any help is very much appreciated.... ☺️
