std::set<Key,Compare,Allocator>::rend, std::set<Key,Compare,Allocator>::

Returns a reverse iterator to the element following the last element of the reversed set. It corresponds to the element preceding the first element of the non-reversed set

Parameters

(none)

Return value

Reverse iterator to the element following the last element.

Complexity

Constant.

Notes

Because both iterator and const_iterator

libc++ backports crend() to C++98 mode.

Example

#include <iostream>
#include <set>
 
int main()
{
    std::set<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';
    }
}
