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()
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
3-7) Assigns a sequence of characters to the regular expression. The syntax flags are set to f. mark_count()
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 [firstlast)
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.
