...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Compare two sequences for inequality.
template <typename Seq1, typename Seq2> bool operator!=(Seq1 const& a, Seq2 const& b);
a != b
Return type: bool
Requirements:
For each element, e1
,
in sequence a
, and for
each element, e2
, in
sequence b
, a == b
is a valid expression returning a
type that is convertible to bool.
An attempt to compare two Sequences of different lengths results in a compile time error.
Semantics:
Returns !(a == b).
