regex_iterator();	(1)	(since C++11)
regex_iterator(BidirIt a, BidirIt b,                const regex_type& re,                std::regex_constants::match_flag_type m =                    std::regex_constants::match_default);	(2)	(since C++11)
regex_iterator(const regex_iterator&);	(3)	(since C++11)

Constructs a new regex_iterator:

1) Default constructor. Constructs an end-of-sequence iterator.

2) Constructs a regex_iterator from the sequence of characters [a, b), the regular expression re, and a flag m that governs matching behavior. This constructor performs an initial call to std::regex_search with this data. If the result of this initial call is false, *this is set to an end-of-sequence iterator.

3) Copies a regex_iterator.

Parameters

a	-	BidirIt to the beginning of the target character sequence
b	-	BidirIt to the end of the targe character sequence
re	-	regular expression used to search the target character sequence
m	-	flags that govern the behavior of re
