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.
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 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.

const_reference std::match_results< _Bi_iter, _Allocator >::operator[] | ( | size_type | __sub | ) | const [inline] |
Gets a sub_match reference for the match or submatch.
__sub | indicates the submatch. |
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.
difference_type std::match_results< _Bi_iter, _Allocator >::position | ( | size_type | __sub = 0 | ) | const [inline] |
Gets the offset of the beginning of the indicated submatch.
__sub | indicates the submatch. |
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.
Returns -1 if __sub
is out of range.
const_reference std::match_results< _Bi_iter, _Allocator >::prefix | ( | ) | const [inline] |
Gets a sub_match representing the match prefix.
This function gets a reference to a sub_match object representing the part of the target range between the start of the target range and the start of the match.

__sub | indicates the submatch. |
This function gets the submatch (or match, if __sub
is zero) extracted from the target range and converted to the associated string type.
