reverse_iterator rend() noexcept;	(1)	(since C++11) (constexpr since C++17)
const_reverse_iterator rend() const noexcept;	(2)	(since C++11) (constexpr since C++17)
const_reverse_iterator crend() const noexcept;	(3)	(since C++11) (constexpr since C++17)

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

Return value

Reverse iterator to the element following the last element.

Complexity

Constant.

Example

Run this code

#include <algorithm>
#include <iostream>
#include <array>

int main()
{
    std::array<int, 11> a{1, 11, 11, 35, 0, 12, 79, 76, 76, 69, 40};

    // Print elements of container in reverse order using const_reverse_iterator's.
    std::for_each(a.crbegin(), a.crend(), [](int e){ std::cout << e << ' '; });
    std::cout << '\n';

    // Modify each element of container using non-const reverse_iterator's.
    std::for_each(a.rbegin(), a.rend(), [](int& e){ e += 32; });

    // Print elements as chars in reverse order using const_reverse_iterator's.
    std::for_each(a.crbegin(), a.crend(), [](char e){ std::cout << e; });
    std::cout << '\n';
}

Output:

40 69 76 76 79 12 0 35 11 11 1
