std::set<Key,Compare,Allocator>:: end, std::set<Key,Compare,Allocator>:: cend

Returns an iterator past the last element of * this .

This returned iterator only acts as a sentinel. It is not guaranteed to be dereferenceable .

Return value

Iterator past the last element.

Complexity

Constant.

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.

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

Example

#include <algorithm>
#include <iostream>
#include <set>
int main()
{
    std::set<int> set{3, 1, 4, 1, 5, 9, 2, 6, 5};
    std::for_each(set.cbegin(), set.cend(), [](int x)
    {
        std::cout << x << ' ';
    });
    std::cout << '\n';
}
