1) Default constructor. Constructs an end-of-sequence iterator.
2) Constructs a
regex_iteratorfrom the sequence of characters
[a, b), the regular expression
re, and a flag
mthat 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
4) The overload 2 is not allowed to be called with a temporary regex, since the returned iterator would be immediately invalidated.
