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.
Example
#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.
