It's ok it doesn't hurt too much ;) he he
anyway at least we know you got the message now.

Of course we don't expect you to know all the rules straight off. If you look in my signature there's...

No they are opposite.

c = *a; //You are assigning the value that a points to *into* c
*a = c ; //you are assigning the value in c into what a points to

You always assign RHS to LHS, left to...

He he, well like they always say:
"Big red and firey, always late"

I think both goes on the stack both times. Would only go on the heap/free store if you use the 'new' keyword.

Yeah and put [ CODE ] [/ CODE ] around JUST the code not the whole...

Wow how old are you ? I'd expect to find you at slashdot rather than daniweb.:cheesy: I've read about those days, you submitted your code and didn't get output until that afternoon or maybe the next...

Well ok I concede that was perhaps a little strong.

But you are changing tack with the UML arguement. UML is just a method for designing, the field is much narrower you don't 'create' with it. UML...

No no no no no I'm sorry that's completely the wrong way around. (system("pause")/fflush(stdin) getch()/kbhit() are not wood (the language) they are prefabricated table legs/lego bricks made for...

But it is clearly defined in the document to which I posted a link. It is important to understand in great depth the tools you work with. It is very possible for a large project to have potentialy...

At last the calvary arrives, I was starting to feel like Genral Custer!

You are running preprocessor ONLY you said



Did you read the material I posted?

It must vary depending on the compiler, here's a good llink for the GNU C Preprocessor. (the one I am using)

I stated I was guessing and if I have any good material I would quote it.

I came to this conclusion by thinking about it and applying a process of elimination in my mind, by thinking about how a...

I'm guessing here, but I recon they cancel each other out.

All directives run on each instance, so:

Preprocessor finds the first instance of a and runs ALL directives on it
a = b = a
Then...

Doh! ! I can't believe I am soooo thick!

It swaps every instance of a and b so

printf("%d %d", a, b);

becomes

printf("%d %d", b, a);

You havn't done anything with your definitions, try this:

#include <stdio.h>
#define a_b

int main(void)
{
#ifdef a_b
int a = 20, b = 30;
#endif

Strictly that's not true because 1 is divisible by 1 and itself, but 1 isn't prime. I prefer:

A prime number has precisely two positive integer factors.

Drat, just when you think you know something, it turns out you don't know squat.

I did know hexidecimal was base 16, luckily I don't have to deal with it on a daily basis so I guess I'm losing...
