std::multimap<Key,T,Compare,Allocator>::end, std::multimap<Key,T,Compare,Allocator>::cend

Since C++11

Returns an iterator to the element following the last element of the multimap.

# Declarations

iterator end();

(noexcept since C++11)

const_iterator end() const;

(noexcept since C++11)

const_iterator cend() const noexcept;

(since C++11)

# Return value

Iterator to the element following the last element.

# Notes

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

#include <algorithm>
