basic_string& assign(const basic_string& str);
Effects: Equivalent to assign(str, 0, npos).
Returns: *this.
basic_string& assign(basic_string&& str) noexcept;
Effects: The function replaces the string controlled by *this with a string of length str.size() whose elements are a copy of the string controlled by str. [ Note: A valid implementation is swap(str). — end note ]
Returns: *this.
basic_string&
assign(const basic_string& str, size_type pos,
size_type n);
Requires: pos <= str.size()
Throws: out_of_range if pos > str.size().
Effects: Determines the effective length rlen of the string to assign as the smaller of n and str.size() - pos and calls assign(str.data() + pos rlen).
Returns: *this.
basic_string& assign(const charT* s, size_type n);
Requires: s points to an array of at least n elements of charT.
Throws: length_error if n > max_size().
Effects: Replaces the string controlled by *this with a string of length n whose elements are a copy of those pointed to by s.
Returns: *this.
basic_string& assign(const charT* s);
Requires: s points to an array of at least traits::length(s) + 1 elements of charT.
Effects: Calls assign(s, traits::length(s)).
Returns: *this.
basic_string& assign(initializer_list<charT> il);
Effects: Calls assign(il.begin(), il.size()).
*this.
basic_string& assign(size_type n, charT c);
Effects: Equivalent to assign(basic_string(n, c)).
Returns: *this.
template<class InputIterator>
basic_string& assign(InputIterator first, InputIterator last);
Effects: Equivalent to assign(basic_string(first, last)).
Returns: *this.
