class std::sub_match< _BiIter >"A sequence of characters matched by a particular marked sub-expression.
An object of this class is essentially a pair of iterators marking a matched subexpression within a regular expression pattern match. Such objects can be converted to and compared with std::basic_string objects of a similar base character type as the pattern matched by the regular expression.
The iterators that make up the pair are the usual half-open interval referencing the actual original pattern matched.

A convenience wrapper for creating a pair from two objects.
Parameters
Returns
The C++98 standard says the objects are passed by reference-to-const, but C++03 says they are passed by value (this was LWG issue #181).
Since C++11 they have been passed by forwarding reference and then forwarded to the new members of the pair. To create a pair with a member of reference type, pass a reference_wrapper to this function.

Defines a lexicographical order for pairs.
For two pairs of the same type, P is ordered before Q if P.first is less than Q.first, or if P.first and Q.first are equivalent (neither is less than the other) and P.second is less than Q.second.
