Compare two sequences for equality.
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:
For each element, e1,
in sequence a, and for
each element, e2, in
sequence b, e1 == e2 returns true. For any 2 zero length
Sequence(s), e and f, e == f returns
true.
