hey just a quick clarification, does the arguments like arg0, arg1, ... also add towards the max 50 identifier count?

ANONYMOUS wrote It does seem like this question is an issue with semantics ( which has happened before (https secure.csse.uwa.edu.au run help2002?p np opt U463 year 2019)) and being such a minute detail of the system call. It seems, at least, possi...

ANONYMOUS wrote Thanks for the link. However, unless I'm misinterpreting it, that thread ended unresolved too. Dr. McDonald's only contribution in that thread was a non-answer (below) All the other messages seem to be speculation, where the same argu...

After going through multiple years of forums, I believe I found an answer to this specific question here https secure.csse.uwa.edu.au run help2002?p np opt U215 year 2019 You also note that the question has similar phrasing to questions 8, 10, and 1...

Making a new thread about this because I think it's worth getting to the bottom of the issue. Question 20 is either an unexplained trick question or a mistake in the sample answers. I'd like to explain why I think it is, or should be treated as, the l...

well, not really sure about this either, but in my opinion it really comes down to technicality, since after the fork, the code doesn't terminate, so we can either call fork() again somewhere outside the function, or call the function more than one t...

I'm not really sure, but I believe the answer is D because the fork() system call doesn't exist on Windows, which is why it isn't guaranteed to work.

I don't know what Chris had mind, it could be a trick question (note the 'always be true'). Suppose I write a complete C code with a main() and do not call this function?

I don't understand why the answer to question 20 was D, rather than C, is anyone able to explain? Thank you ) (20) Consider the following C code void function(void) fork(); fork(); printf("hello world n"); If the above code ...

Hello. Could someone explain why the answer to question 3 is A? Thanks

probably the day results are released, which is next Friday

Hello. Just wondering when i can get the solutions for midterm exam. Thanks

define N 10; is not invalid syntax (it's for the preprocessor, not for the C compiler).

You can find this state in the diagram found in lecture 8, slide page 14, or alternatively here https teaching.csse.uwa.edu.au units CITS2002 lectures lecture08 14.html

(10) Consider the following code which contains a common error c define N 10; void function(void) A) char array N ; B) int x 2 N; C) for(int i 0 ; i N i) printf(" c n", array i ); Which of the follo...

I was also confused by this one. I understood that the suspend state was distinct from the ready state, and that when a processor in the ready state is moved into swap, it stops being in the ready state. I didn't see the ready suspend thing ...

Hi, I was lost that why is waiting not a traditional process state.

This is correct.

ANONYMOUS wrote That's correct.

ANONYMOUS wrote This is the correct reasoning.

Not sure if I am correct but the reason why B (int x 2 10;;) is because it would take the second semicolon as an empty statement so it'll be read as int x 2 10; ; which would not affect the program itself but will just look weird and isn't good ...

Not OP but would it be because it depends on the bits (i.e. 32-bit or 64-bit) where 32-bit is 4 bytes per integer but something like 16-bit will give 2 bits so it'll be value of 200. That's why the answer is B. Because the value byte of each object i...

First, I think C is also right answer because the question asks for "reason",and option C is the "result" caused by the fail. Option D is correct because it presents a scenario that is not applicable to the fork() system call. Since fork() does not ac...

Wouldn't this mean that A and B are incorrect. Since we define N as 10; which includes the semicolon. That means for A, Substitution char array 10; ; The semicolon causes a syntax error here. For B, int x 2 10;; This results in a double semico...

(20) Which of the following is NOT a reason for the fork system call failing? A. the user already has too many processes running. B. The whole computer system has exhausted is available memory. C. the value returned by fork is -1. D. the parameter passed...

ANONYMOUS wrote Line A is not valid, and line C does not contain a syntax error. Cut-paste-compile the code if you need to.

How can the answer still be A when line A is valid and line C contains a syntax error?

ANONYMOUS wrote If the size of one integer was always 4 bytes, then the answer would be A) 400 bytes . The C11 standard (nor any C standard) does not specify sizeof(int) to always be 4. For what reasons might sizeof(int) not be 4?

ANONYMOUS wrote Definitely is a p9 - reload the PDF page in your browser (the old PDF is still in its cache).

This is not the right answer bro, I'm 100 sure the answer of Q10 is C not A

Here

Where did you get the answers? There is still no page 9 in the sample test

Hi Chris, I was lost with question 7, I thought the answer maybe A but it is B can you please explain. Thanks )

Hi I have checked the practice test paper and there is no page 9 with solutions from the Mid-Semester test section. I am just wondering if it wasn't able to upload or it has been posted elsewhere? Regards,

ANONYMOUS wrote (indeed; it's still Tuesday) You may now find the solutions on the last page (p9) of the sample test. Good luck,

Hi, I was just wondering where I could find the solutions to the practice test, as it is mentioned that they would be released today on the mid-semester test information page. Thanks in advance, Jerry

N is replaced with "10;" - so the syntax becomes valid.. for(int i 0; i 10; i)

Oh, I see, there's a semicolon after the N... oops. I'll be mindful of that in future. When you say both your points, are you saying that for(int i 0 ; i N i) is valid syntax? Or are you talking about the response above mine? Thanks for the res...

ANONYMOUS wrote I'm afraid both of your points are incorrect. Please see https secure.csse.uwa.edu.au run help2002?p np opt B72

Line A is valid; the syntax char array N ; declares an array named "array" and allocates enough memory for N-many chars to be stored in the array, (see here (https www.geeksforgeeks.org c-arrays )). There's definitely a syntax error in line C th...

for line C, it is for(int i 0 ; i N i) ... seems the answer should be line A. But is it okay that it doesn't have a semicolon after i N?

The define preprocessor directive, when used as define pattern1 pattern2 , results in all later instances of pattern1 being replaced by pattern2 . In this example, N is not a variable, and is not being initialised, but ev...

ANONYMOUS wrote B) is certainly the correct answer. Yes, it's undoubtably defined in the (huge) standards document, but there is no requirement to read it to answer the question. We've highlighted that C is quite a small language by contemporary stan...

N 10;

define N 10; being wrongly initialised, I think all of the above should be the correct answer, as it makes N 10, resulting in the error in other statements as well.

I recommend that you review this statement.

The question is about the syntax error but initialising N has a syntax error itself. i.e. define N 10; Does option B, int x 2 N; , count as a syntax error?

This is the correct 'answer', thank you. I wonder how why the OP has break statements in the posted question. Perhaps they had been introduced by an IDE trying to be helpful by (incorrectly) anticipating what was coming 'next' ??

The code in the question doesn't have any breaks in the switch statement, remember that c has switch fall through by default, which should make the answer self evident.

ANONYMOUS wrote You're right. I think there is a typo in the answer. None of the options are correct. However, there is one option that is very close to the correct answer. Can you see which one it is?

ANONYMOUS wrote One place to the left means index - 1 . e.g. If an integer is at index 3 it will be at index 2 after the code runs. Likewise, if an integer is at index 1, then after the code runs it will be at index 0. I hope that makes sense.

For the question 12 void function(void) for (int i 0; i 5; i) switch (i 3) case 0 printf(" i ", i); break; case 1 printf(" i ", i); break; ...
