Returns a reverse iterator to the character following the last character of the reversed view. It corresponds to the character preceding the first character of the non-reversed view. This character acts as a placeholder, attempting to access it results in undefined behavior.

[edit] Parameters
(none)
[edit] Return value
const_reverse_iterator to the character following the last 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(), str_view.rend(), out_it); *out_it = '\n'; std::copy(str_view.crbegin(), str_view.crend(), out_it); *out_it = '\n'; }
Output:
fedcba fedcba
