In addition to the more helpful comments you have already received,
"string" is an identifier reserved for use by the implementation, and
you should thus not use it. (IIRC, that statement only applies if
you've included <string.h>.)
His use of the identifier does not have external linkage, nor is at file
scope, so he should be fine, at least if he hasn't included string.h or
stdlib.h [possibly even if he has, but i don't know in that case]
Irrelevant. There is nothing to prevent ISO C 200x from using
that identifier, because it is reserved explicitly for such use.
So, a new compiler comes along, and suddenly the above code
stops working. With or without string.h.
