array of strings?

[Robert]

Hi,

Is there some way of using an array of strings? Like in basic?
I know you have to create an array of chars so i think it has to
be an 2d array or something...

Really stuck here... Thanks in advance,

Robert

Alright, because i didn't was very clear (srry for that) i'll
try again... I am used to basic so here is an example of what i
mean in basic...

dim somestring(1 to 10) as string

I maybe need to resize both the array and the actual string
in runtime so can someone please give me an example of that?

btw i looked in that other topic but didn't find where i was
searching for...

There are at least a couple of ways to define/use an "array of strings".

First off, strings (in C) are arrays of char, with contents that are terminated
by a \0 char.

Thus
char String[10] = "string";
is a string, as is
char *String = "string";
(actually, in this case, the String variable is a pointer, but it points to an
array of char, terminated with a \0, so it points to a "string");

So, how do we get an array of strings? We get arrays of arrays of chars, or
arrays of pointers to chars.

Thus
char StringArray[3][10] = {"string1", "string2", "string3"};
is an array of strings, as is
char *StringArray[3] = {"string1", "string2", "string3"};

Does that help?

Robert...

You might find the functions at:

http://www.iedu.com/mrd/c/tokenize.c and
http://www.iedu.com/mrd/c/tokfile.c

of some interest. These programs defer allocation of storage
until the exact size of the storage needed is known (for both
pointer and char arrays.)
