thanks a lot hammer! part of my preprocessor is now done! :D
when things go right c programming is fuuun!! :p
moving to the next step, replacing the #define with something else... thanks to...

well i tried and i continue trying... but i will use that printf suggestion.. hope i can find where the error occurs it is driving me nuts!!!

i don't realise why this program gives segmentation fault when executed... here's the code


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main (int argc, char* argv[]){

but that darn segmentation fault won't go away!
here's how...

what a mistake... but it's fixed now!!

that seems just perfect for the current project i have in hands, a different kind of c pre-processor :D
thanks a lot you guys!!

could anyone of you c gurus please explain me how a hash table is implemented? a friend of mine said that it would save two things, a char and the value of that char and when the char...

well i have two books, c programming language by rithchie and one in portuguese... guess i gotta read them better before i come here asking these type of questions... :o
but thanks for the help...
