Re: [Dev-C++] Tokenize function

[Derek C. <de...@ci...>]

You've just mixed in too much test code with the production stuff!

As given, the tokenizar function works fine.

However combine it with the main program given and the problem is that
 array[] in the main program is not initialised. Trying to dereference
uninitialised pointers (in the printf) doesn't usually mean that good
things happen!

You have a general problem with tokenizar in that there is no way to
get the tokens back to the main program. You might want to add another
parameter or two, i.e. make the signature void tokenizar(char
*palavra, char* array[], unsigned int size_of_array)

Now you can pass in the token array and get results back.
