NAME
std::basic_regex::assign - std::basic_regex::assign

Synopsis
   basic_regex& assign( const basic_regex& other ); (1) (since C++11)
   basic_regex& assign( basic_regex&& other ) noexcept; (2) (since C++11)
   basic_regex& assign( const CharT* s,
                        flag_type f = (3) (since C++11)
   std::regex_constants::ECMAScript );
   basic_regex& assign( const CharT* ptr, std::size_t count,
                        flag_type f = (4) (since C++11)
   std::regex_constants::ECMAScript );
   template< class ST, class SA >
   basic_regex& assign( const std::basic_string<CharT,ST,SA>& str, (5) (since C++11)
                        flag_type f =
   std::regex_constants::ECMAScript );
   template< class InputIt >
   basic_regex& assign( InputIt first, InputIt last, (6) (since C++11)
                        flag_type f =
   std::regex_constants::ECMAScript );
   basic_regex& assign( std::initializer_list<CharT> ilist,

   std::regex_constants::ECMAScript );
   Assigns the contents to the regular expression.
   1) Assigns the contents of other. flags() and mark_count() are equivalent to the
   values of other.flags() and other.mark_count() after the call.
   2) Assigns the contents of other using move semantics. flags() and mark_count() are
   equivalent to the values of other.flags() and other.mark_count() before the
   assignment. After the call, other is in a valid, but unspecified state.
   3-7) Assigns a sequence of characters to the regular expression. The syntax flags
   are set to f. mark_count() returns the number of marked subexpressions within the
   resulting subexpression after the call.
   3) Assigns a null-terminated string pointed to by s.
   4) Assigns a sequence of count characters, pointed to by s.
   5) Assigns the string str.
   6) Assigns the characters in the range [first, last).
   7) Assigns the characters in the initializer list ilist.

Parameters
   other - another regular expression to assign
   s - pointer to a character sequence to assign
   str - string to assign
   first, last - the range of characters to assign
   ilist - initializer list containing characters to assign

Type requirements
   -
   InputIt must meet the requirements of LegacyInputIterator.

Return value
   *this

Exceptions
   1) May throw implementation-defined exceptions.
   3-7) std::regex_error if the supplied regular expression is not valid. The object is
   not modified in that case.
