public member function
<regex>
std::regex_iterator::operator*const value_type& operator*() const;
Dereference regex_iterator
Returns a reference to the match_results object the iterator is pointing to.This operator shall not be applied to end-of-sequence iterators (the behavior of such an operation is undefined).
regex_iterator objects keep a match_results object internally whose reference is returned by a call to this function. The value of this object may be modified by a call to either operator++ or operator= on the regex_iterator object.
