constexpr const_reverse_iterator rbegin() const noexcept;
(since C++17)
constexpr const_reverse_iterator crbegin() const noexcept;
(since C++17)
Returns a reverse iterator to the first character of the reversed view. It corresponds to the last character of the non-reversed view.
[edit] Parameters
(none)
[edit] Return value
const_reverse_iterator to the first character.
[edit] Complexity
Constant.
[edit] Example
Run this code
#include <algorithm> #include <iostream> #include <iterator> #include <string_view> int main() { std::ostream_iterator <char> out_it(std::cout ); std::string_view str_view("abcdef"); std::copy (str_view.rbegin(), std::next (str_view.rbegin(), 3), out_it); *out_it = '\n'; std::copy (str_view.crbegin(), std::next (str_view.crbegin(), 3), out_it); *out_it = '\n'; }
Output:
