1st link takes you to a 700+ page document telling you all you need to know.

It seems Arbus is more confused about multi-dimension arrays than you are.

> But you are passing multidimensional array. So declare A accordingly (char **A[3] or char *A[3][3]).
But neither of these things are anywhere near char A[][3][3], which is what the OP had to begin with. char (*A)[3][3] would have been OK, but your permutations didn't go that far.

All that was needed was fixing how to pass the array parameter to the function in the first instance. Everything else was OK.

#include <stdio.h>

void displayboard(char board[][3][3]);

int main()
{
  char board[3][3][3] = {
    {
      { "123" },
      { "456" },
      { "789" },
    },
    {
      { "ABC" },
      { "DEF" },
      { "GHI" },
    },
    {
      { "!%^" },
      { "&()" },
      { "+-=" },
    },
  };
  displayboard(board);  //!! No *, & or subscripts here!!
  return 0;
}

void displayboard(char board[][3][3]) {
  int i, j, k;
  for ( i = 0 ; i < 3 ; i++ ) {
    for ( j = 0 ; j < 3 ; j++ ) {
      for ( k = 0 ; k < 3 ; k++ ) {
        printf("%c ", board[i][j][k] );
      }
      printf("\n");
    }
    printf("---\n");
  }
}

Not a single * to be seen!

1) What are the rules of this function structure? A link to a website explaining it would be awesome.
This is how function parameters were defined in what is known as "K&R-C", which existed before ANSI/ISO got in on the act.
http://stackoverflow.com/questions/22500/what-are-the-major-differences-between-ansi-c-and-kr-c

2) What are the advantages of this function structure?
Really old compilers will still work.
> Are there disadvantages?
No cross-function type-checking would be one biggie.

2.A) If there is no difference, Is it just a style of writting parameters? Is there an advantage to the style itself?
No, see above.

2.B) Is there any difference in the machine code generated by the compiler between this style and the standard style?
The caller might generate different code, because it doesn't really know what the prototype for the function should be.

3) Is there a name or term to this function structure? If so what is it?
See above.

4) Is this standard C or is this a gcc extension of some sort?
No, it's a backward compatibility thing for the dim and distant past.

It depends on how you correct your spelling mistake.

> far and near are reserved keywords in C (not standard, but common, it is a relic from the times of 16bit architectures)
They're reserved identifiers only in compilers for the x86. C itself pre-dates DOS (and the x86), and didn't have these keywords. Likewise, compilers for other languages which ran on x86 also needed to know about the hacky segmented memory models.

What many modern compilers have in some system header file (particularly any with a DOS heritage) are

#define near /*not useful in 32-bit*/
#define far /*not useful in 32-bit*/

So that when used in the correct context, say far char *ptr; // 16-bit would become char *ptr; // 32-bit through the magic of the pre-processor.

But using them inappropriately, say void foo(int near,int far){dofunc(near,far);}//Syntax error, expected primary expression before , and ) expands to void foo(int ,int ){dofunc(,);}//Syntax error, expected primary expression before , and )

Well on the Linux box, you do this.

gcc -g prog.c
valgrind ./a.out

valgrind will tell you a lot about all kinds of memory abuse (overrun, use after free, uninitialised accesses etc).

When it is clean in valgrind, have another go on windows.

I dunno, what have you been doing all this time?

http://xkcd.com/303/

For a C++ program, there is precious little C++ in the code at all.

Apart from a few reference parameters (some for no good reason I can see), and the for loop declarations, this could so easily pass for being a C program.

If you want it to be more like C++, then do these things:
1. Replace all printf with cout
2. Replace all char arrays with std::string; for one thing, it reduces strAddChar() to one line of code.
3. Replace all other arrays with std::vector

Somewhere in the code there should be at least one 'class' with suitable member variables and methods.

But then again, you've had only 30 hours, so perhaps making classes is beyond you.

If you've been taught all these things (OK, assuming a level of competence in the teacher here, but what the heck, it might be true), then your tutor is going to be expecting to see some real C++.

So you took someone else's old C and made it make a couple of noises - whoop-ee-doo.

Actually, I don't really care, since we still can't tell what it is you're ACTUALLY capable of doing yourself.

What is for sure is that no one here is interested in helping some wannabe get a grade they don't deserve, which might lead them to getting a job which they are incapable of doing. Unlike student homework, the answers to job assignments CANNOT be found …

Why would someone want explanation for code they've written?

But then again, why bother pretending you can program when you can lift code off the net?

> #include<malloc.h> /* You need this if on UNIX or LINUX */
This is all wrong.
malloc is prototyped in stdlib.h

> p = (char *)malloc(sizeof(words));
You don't need to cast malloc in C programs.

Have you tried it without the cast? Did you get any error messages?

These perhaps?
"implicit conversion of int to char*" -> you didn't include stdlib.h
"conversion of void* to char*" -> you're using a C++ compiler to compile C code.

> 4. sizeof() ; function says it all . It means size of the "data" in this case "words".
sizeof is an operator, not a function.
Passing an array to a function yields a pointer to the first element of that array.

The parentheses are optional when applying sizeof to a variable.
p = malloc(sizeof words );

Other issues:
- you didn't check malloc for success
- you didn't describe free(), the essential complement to using malloc.

C'mon - it tells you the line, how many identifiers are on that line?

Do a search for each one of them, and figure out which isn't present.

Hint: identifiers are case sensitive.

Eclipse doesn't make sound - it's an editor wrapped around a compiler.

What matters is what your OS is, what API's you have access to and the kind of programs you're creating.

Eclipse runs on many platforms, and can generate project types for many different programs.

So explaining say "sound for a Linux console" wouldn't make a damn bit of use to you if you're interested in "windows GUI programs".

char buff[] = "My dog ate my homework";
char *p = buff;
int n;
while ( sscanf( p, "%s%n", word, &n ) == 1 ) {
  p += n;  // advance through the buffer
}

How about posting your attempt.

Rather than just describing to us rather unconvincingly that you've made any attempt at all.

We get a lot of "I tried but it didn't work, here's my question, can you do it for me, kthxbye" types.

Weird - your printf statement looks exactly the same, except for the fact that you said you changed it.

Thanks for playing.

Did you compile it?

If you don't even understand the question, then go and talk to your tutor.

If you're stuck on part of the answer, then post some relevant code and ask a question about that code (in the context of your problem).
Eg. I think I need a list of bids, but my list keeps dropping the latest bid. Here is my code.

Don't just dump your assignment fresh from the email message from your tutor then sod off down the beach or something, expecting us to take up your slack - it ain't gonna happen.

> int dataLen = recv(client, recvBuffer, 1024, 0);
You're assuming several things (all of which are false, eventually)

1. That for every "message" sent, you get "message". STREAM sockets can fragment the message (only the byte order is guaranteed). So you might get "mess" or even "messagemessageme".

2. That every message has a \0 (to make it a proper string). If you don't send one, then there isn't one added automatically.
Typically, this means using sizeof(buff)-1 in the recv call to allow for easy appending of a \0 if you need to.

3. Use the length before doing anything else with the message.
len = recv....
if ( len > 0 ) buff[len] = '\0';

Then you can treat buff as a proper c-string.

So why can't you recursively evaluate A -> B -> C ?

a1 = eval( eval(a2) + eval(a3) );

When you get to a3, you see that you need to do another eval()

Is this a plan?

The only problem you need to watch out for is if there is a cycle in the expressions.

That's a spectacularly useless manual page AD.

Not only is there no %n, there's no %i %p or %[ either.

I just threw in some crumbs to show the general idea of how the problem was solvable.

Tarting it up for security and suitable for compiling with whatever C.X.Y compiler was left as an exercise for the readers :)

int s, e;
scanf(" %n%s%n %d", &s, R, &e, &n);
int len = e - s;

No, you're wrong.
argc is a COUNT of the number of arguments, it has nothing to do with the value of any single argument.

All the args are in argv[] as a series of string, which you need to covert.

So a long long int would be a string in argv[1] with
./myprog 1234567890987654321

You could pad your format string with %n conversions, which would give you a length with a minimal calculation.

Because passing an array to a function reduces it to just a pointer to the first element, and the size information is lost.

Just like it were a regular function.

It's quite clear by now that this thread is nothing but a magnet for sig-spammers with it's high view count

400*400 is 160000

This is somewhat larger than the 16 bits (max 32767) that your ancient TurboC compiler can manage.

UPGRADE!

You could post some ACTUAL code, not 1-line entries out of the API manual.

Then there's the spam

A fine coat, made from the skin from the fingers of 1000 spammers.

As well as being a somewhat rare commodity, the beneficial side effect is that 100 of them can no longer type :icon_twisted:

Most of the IDEs I know save the compilation/interpretation to external tools.

So a simple wrapper around
- edit file using an editor
- pass file to compiler
- gather error messages.

All of this is mundane stuff compared to writing a compiler.

Maybe grab the source code for code::blocks and start reading.

The same code was round a few days ago, including the same mistakes.

My guess is that this is a "fix the errors" homework assignment just dumped on the board.
