| iterator end(); |
(1) | (noexcept since C++11) |
| const_iterator end() const; |
(2) | (noexcept since C++11) |
| const_iterator cend() const noexcept; |
(3) | (since C++11) |
Returns an iterator to the element following the last element of the multiset.
This element acts as a placeholder; attempting to access it results in undefined behavior.
Contents |
[edit] Parameters
(none)
[edit] Return value
Iterator to the element following the last element.
[edit] 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.
[edit] Example
Run this code
#include <iostream> #include <iterator> #include <set> #include <string> int main() { const std::multiset<std::string> words = { "some", "not", "sorted", "words", "will", "come", "out", "sorted", }; for (auto it = words.begin(); it != words.end(); ) { auto count = words.count(*it); std::cout << *it << ":\t" << count << '\n'; std::advance(it, count); // all count elements have equivalent keys } }
Output:
come: 1 not: 1 out: 1 some: 1 sorted: 2 will: 1 words: 1
