Thread: strtok() and strcpy

hi, im just learning c and im trying to copy the token to a 2 dimension char array but the array( eq1[][] ) just gets filled with nulls. i cant figure out what im doing wrong...

Code:

void tokenize(void){
   extern char equation[];
   extern eq1[];
   int i = 0;
   char *token;

   token = strtok( equation, " ");
   while ( token != NULL ){
      printf( "token is %s\n", token);
      strcpy(eq1[i], token);
      token = strtok( NULL, " ")
      printf("eq is %s\n", eq1[i]);
      ++i;
   }
}

if anyone could help me out id really appreciate it

Presumably you have eq1 defined in your function correctly? Right now it's not a two-d array for you to fill.

its just a typo, its actually declared like:

extern char eq1[][];

the strtok seems to work, the printf's work but wheni display eq1 i get (null)

its the only typo, and it is the actual code im using. i just cant figure out why im getting (null) in eq1 instead of token

Like we all didn't see the missing semicolon either.
