std::flat_multiset<Key,Compare,KeyContainer>::rend, std::flat_multiset<Key,Compare,KeyContainer>::crend

Since C++23

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

# Declarations

reverse_iterator rend() noexcept;

(since C++23)

const_reverse_iterator rend() const noexcept;

(since C++23)

const_reverse_iterator crend() const noexcept;

(since C++23)

# Return value

Reverse iterator to the element following the last element.

# Notes

Because both iterator and const_iterator are constant iterators (and may in fact be the same type), it is not possible to mutate the elements of the container through an iterator returned by any of these member functions.

# Example

#include <iostream>
#include <flat_set>
 
int main()
{
    std::flat_multiset<unsigned> rep{1, 2, 3, 4, 1, 2, 3, 4};
 
    for (auto it = rep.crbegin(); it != rep.crend(); ++it)
    {
        for (auto n = *it; n > 0; --n)
            std::cout << "⏼" << ' ';
        std::cout << '\n';
    }
}
