NAME¶

std::list::end,std::list::cend - std::list::end,std::list::cend

Synopsis¶

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 list.

This element acts as a placeholder; attempting to access it results in undefined
behavior.

Parameters¶

(none)

Return value¶

Iterator to the element following the last element.

Complexity¶

Constant.

Notes¶

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

Example¶

// Run this code

#include <algorithm>
#include <iostream>
#include <numeric>
#include <string>
#include <list>

int main()
{
std::list<int> nums{1, 2, 4, 8, 16};
std::list<std::string> fruits{"orange", "apple", "raspberry"};
std::list<char> empty;

// Print list.
std::for_each(nums.begin(), nums.end(), [](const int n) { std::cout << n << ' '; });
std::cout << '\n';

// Sums all integers in the list nums (if any), printing only the result.
std::cout << "Sum of nums: "
<< std::accumulate(nums.begin(), nums.end(), 0) << '\n';

// Prints the first fruit in the list fruits, checking if there is any.
if (!fruits.empty())
std::cout << "First fruit: " << *fruits.begin() << '\n';

if (empty.begin() == empty.end())
std::cout << "list 'empty' is indeed empty.\n";
}

Output:¶

1 2 4 8 16
Sum of nums: 31
First fruit: orange
list 'empty' is indeed empty.
