Yes.  Pointer ineqalities are only valid for pointers that "are members of the
same aggregate object", with one exception: "If P points to the last member of
an array object, the pointer expression P+1 compares higher than P, even
though P+1 does not point to a member of the array object."  (3.3.8 Relational
operators).
