These functions perform formatted substitution of the matched
character sequences into their target. The format specifiers and escape
sequences accepted by these functions are determined by their flags
parameter as documented above.

class std::match_results< _Bi_iter, _Alloc >"The results of a match or search operation.
A collection of character sequences representing the result of a regular expression match. Storage for the collection is allocated and freed as necessary by the member functions of class template match_results.
This class satisfies the Sequence requirements, with the exception that only the operations defined for a const-qualified Sequence are supported.
The sub_match object stored at index 0 represents sub-expression 0, i.e. the whole match. In this case the sub_match member matched is always true. The sub_match object stored at index n denotes what matched the marked sub-expression n within the matched expression. If the sub-expression n participated in a regular expression match then the sub_match member matched evaluates to true, and members first and second denote the range of characters [first, second) which formed that match. Otherwise matched is false, and members first and second point to the end of the sequence that was searched.

Gets the length of the indicated submatch.
Parameters
Precondition
This function returns the length of the indicated submatch, or the length of the entire match if __sub is zero (the default).
Definition at line 1728 of file regex.h.
Gets the number of matches and submatches. The number of matches for a given regular expression will be either 0 if there was no match or mark_count() + 1 if a match was successful. Some matches may be empty.
Returns

Assigns rhs to *this.
Move-assigns rhs to *this.
Gets a sub_match reference for the match or submatch.
Parameters
Precondition
This function gets a reference to the indicated submatch, or the entire match if __sub is zero.
If __sub >= size() then this function returns a sub_match with a special value indicating no submatch.

Gets the offset of the beginning of the indicated submatch.
Parameters
Precondition
This function returns the offset from the beginning of the target sequence to the beginning of the submatch, unless the value of __sub is zero (the default), in which case this function returns the offset from the beginning of the target sequence to the beginning of the match.
