 (2) 
 (since C++11) 
basic_regex& operator=( const CharT* ptr );
 (3) 
 (since C++11)

Assigns the contents.
1) Copy assignment operator. Assigns the contents of other. Equivalent to assign(other);.
2) Move assignment operator. Assigns the contents of other using move semantics. other is in valid, but unspecified state after the operation. Equivalent to assign(other);.
3) Assigns a null-terminated character string pointed to by ptr. Equivalent to assign(ptr);.
4) Assigns characters contained in initializer list il. Equivalent to assign(il);.
5) Assigns the contents of the string p. Equivalent to assign(p);.

[edit] Parameters
 other

 string containing characters to assign
[edit] Return value
*this
[edit] Exceptions
1) May throw implementation-defined exceptions.
3-5) std::regex_error  if the supplied regular expression is not valid. The object is not modified in that case.
