Hello! I've been trying over and over again to find a way to split a string into an array of strings. I have tried Google, writing the code myself, etc but without any success. I want something like this, so that the array holds every word of a string:


char *message = "this is a test";
char *words[];

words = splitstring(message, " ");

Is this possible? Thanks in advance, storage!

This thread entitled Get splitter function to work may be useful.

I would look into c++ and use Boost.StringAlgorithm

What you are curious about is called string delimination. It is really a rather simple algorithm. Start at the beginning, and go through the array of characters until the character you wish to deliminate by is found. Allocate the memory for 0 to N and then strncpy into the new array for length N. Now record where N was and start the search again. Allocated and strncpy for the new position - N.

Of course, you are going to want to trim the left and right sides of the string of any deliminating characters before you start.

Edit: And in Java it is called tokenizing.

Oluseyi posted a solution to this using std::string and std::vector once. You can find it here.
