I'm sure this is much closer to what they were looking for. On the
other hand, strings are not a native datatype, so you're still using
standard libraries. On many embedded systems, you may not have the
luxury of a standard string class, so you'd be stuck with arrays of
characters. This makes it a little more tricky, since you now have to
deal with the size of the array, who allocates it, etc.
