#
Returns: !(lhs == rhs).
template<class charT, class traits, class Allocator> bool operator!=(const charT* lhs, const basic_string<charT, traits, Allocator>& rhs);

#
Returns: rhs != lhs.
template<class charT, class traits, class Allocator> bool operator!=(const basic_string<charT, traits, Allocator>& lhs, const charT* rhs);

#
Requires: rhs points to an array of at least traits​::​length(rhs) + 1 elements of charT.

Returns: lhs.compare(rhs) != 0.
