You can't return an array directly from a function, but you CAN return
a pointer to the start of the array -- but be careful, you can't use a
pointer to an array that is only local to the function. You will need
to either pass the pre-allocated array into the function or
dynamically allocate memory for the array inside the function and then
return a pointer to that allocated memory. A lot of the string
functions in C do this.
Another option is to wrap the array in a struct and return that (or a
pointer to the struct) ... but even better is to use C++ and use one
of the high-level container classes (like vector).
