std [28.8.1](1)
Objects of specializations of this class represent regular expressions constructed from sequences of character type _Ch_type
.
Storage for the regular expression is allocated and deallocated as necessary by the member functions of this class.

_InputIterator | __last, | ||
flag_type | __f = regex_constants::ECMAScript |
||
) | [inline] |
Constructs a basic regular expression from the range [first, last) interpreted according to the flags in f
.
first | The start of a range containing a valid regular expression. |
last | The end of a range containing a valid regular expression. |
f | The format flags of the regular expression. |
regex_error | if [first, last) is not a valid regular expression. |
std::basic_regex::basic_regex | ( | initializer_list< _Ch_type > | __l, |
flag_type | __f = regex_constants::ECMAScript |
||
) | [inline] |
Constructs a basic regular expression from an initializer list.
l | The initializer list. |
f | The format flags of the regular expression. |
regex_error | if l is not a valid regular expression. |
