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.
