Sorry for the double post, it was an accident.

thanks vijayan121, this solved my problem.

Duoas, i wanted to swap the arrays inside the function...

nop man this won't work.... because i am asking about variable lenght arrays....

check this out::

http://www.ddj.com/cpp/184401444

the way i think it, i try to avoid copying anything than 2 pointers... maybe the thread title is a bit misleading

maybe a moderator could change to something like "swap the pointers to 2 arrays"...

hi guys, it's been a while since i used c for anything so here goes a question tha may seem silly.


I have 2 variable length arrays....



int main()
{
int n = 5;

it seems that this
expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token
error appears when in the declaration of a functions you miss a ; in the end...

searching a bit i found this::

/*
* C99
* 6.5.3.4.2
* The sizeof operator yields the size (in bytes) of its operand,
* which may be an expression or the parenthesized name
* of a...

THANK YOU duoas... i 've been looking this code for one hour before i post here trying to find the error.... can i ask something though:

why sizeof nameval_t was wrong?

I wish a happy 2008 to everyone on this forum.
I just obtained the practise of programming{by the way it seems like a great book...}
and i have the following code for linked list:


#include...

Well....YES...it's stupid i know, but that's how it works....and they are very strict about that.
THANX for your help people...appriciate it....will try to implement some of the things you told...

you are right... the book mentions this trick when it talks about process implementation....

thank you all for your help!!

can you elaborate a bit more, because i still can't quite get it....



shouldn't then be written like this
int (*call_vec[])(void)

thank you both for your answers!

hi guys,

i have the following code:

main.c

#include <unistd.h>
#include <stdio.h>
#include <errno.h>

basically i zipped it with fedora...

thank you all for your help... :)

thanks salem, it works! I understand why your code solves the problem "type the wrong thing"...

hi, i have the following problem::

i want to read a string from the stdin. The string may contain white spaces so {i think} the scanf family of functions is out of the question... I think the most...

thanks salem!

thanks for your answer salem,

so to do this properly i should send the componenets of the struct one by one?

PS:: i didn't mention on my first post that the communication will be in the same...

thanks in advance,
