One way is to try declaring an array of pointers

char **array_of_pointers[];

Now you need to malloc enough space for the number of string pointers you
need

array_of_pointers = (char **)malloc(number_of_strings*sizeof(char *));

Next allocate each of these pointers enough space to hold the required
string

array_of_pointers[0] = (char *)malloc(size_of_string1*sizeof(char));
array_of_pointers[1] = (char *)malloc(size_of_string2*sizeof(char));
etc...

You can fill these arrays with code like

array_of_pointers[0] = "my string";

Hope this helps ?:)
