I gather there will also be some controversy over Q23. b) iii.

Does the subprogram use reference parameters? If it does not then you would have to insert the code to display the swimmer's time inside the subprogram after the loops (which is probably not very good abstraction/programming technique), as the values in mainprogram will not have changed from -1.
I just put add line 265: print swimmer_time

lol, is there something wrong with that?

Did the exact same thing aha but I thought it might be wrong because it was worth 2 marks or something

Ah good, if 15 is A then I've got it right. I was really unsure with 7+8 though, so I definately got them wrong by the looks of it.

15 is not A but D. this is becuase you all global parameters are meant to be in the bracket.
the blogal parameters in this are a,b,c,d

and 17 is B not C. this is because global variables are in the bracket. and the variable first is in the bracket hense it is global.

If you assume that when the variables are altered by the while loops in the subprogram, they do not affect the variables back in mainprogram (which they shouldn't unless they are reference parameters); then that is correct.

If you put the print statement in the main program (between lines 140 - 150) then it will print -1.000 as the swimmers time.

15 is not A but D. this is becuase you all global parameters are meant to be in the bracket.
the blogal parameters in this are a,b,c,d

and 17 is B not C. this is because global variables are in the bracket. and the variable first is in the bracket hense it is global.
You do not have to pass global variables into modules, as their scope is the entire program.

you can post this as often as you like, it's not going to make the wrong answers right

OK guys, I'm 100% confident in all my answers and I'm pretty good at this subject. According to the information in this thread, and some quick book re-reading, pretty sure these are the correct answers:

1.A
2.C
3.D
4.B
5.B
6.C
7.D
8.D
9.B
10.B
11.C
12.A
13.D
14.C
15.A
16.B
17.C
18.A
19.C
20.D

If you have any disputes, feel free to reply and we can work out the question (I'm just trying to compile a list of correct answers for us all)

1) a
2) c
3) d
4) b
5) b
6) c
7) b- i agree d is correct
8) d
9) b
10) b
11) c
12) a
13) d
14) c
15) b- i disagree with A, e.g. parameters point in, return values from functions point out, but i get what sidereal said
16) b
17) c
18) a
19) c
20) b- this one i had trouble understanding cause i thought it was supposed to be improving so it presents where the values are, but i get where D works, damn, should have read the question.

For Question 15, just something else to think about.

If you must put in brackets all variables coming into the module then...

Would M1 (the main program) require 'b' to be in brackets? Assuming M1 is the mainprogram and the module run first when executed, where would it get the value for b from?

2. C
3. D
4. B
5. B - this one was fairly vague IMO.... I might have put down c but I cant remember
6. C
7. D
8. C - I hated this question so much lol i read somewhere that DLL's are usually included in the compilation process ... D made no sense to me
9. B - i could see how it would be A aswell
10. B - i was laughing my ass off at this point
11. C
12. A
13. D
14 .C
15. B - these are the only 2 being passed to that module
16. B
17. I CANT REMEMBER... i think I did B
18. A

I am 100% sure that the following answers are correct:

1 A
2 C
3 D
4 B
5 B
6 C
7 D
8 D
9 B
10B
11C
12A
13D
14C
15A -- ALL of the previous SDD exams pass the result variable to functions (dont ask me why, paper-makers are idiots)
16B
17C
18A
19C
20D


Overall, i was disappointed with the paper. Too easy. Expecting 98%+
