constexpr const_reverse_iterator rend() const noexcept; |  | (since C++17)
constexpr const_reverse_iterator crend() const noexcept; |  | (since C++17)

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.

### Parameters

(none)

### Return value

`const_reverse_iterator` to the character following the last character.

### Complexity

Constant.

### 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
