std::flat_multimap::end,(3) C++ Standard Libary std::flat_multimap::end,(3)

NAME

std::flat_multimap::end, - std::flat_multimap::end,

Synopsis


iterator end() noexcept; (1) (since C++23)
const_iterator end() const noexcept; (2) (since C++23)
const_iterator cend() const noexcept; (3) (since C++23)


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


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

// Run this code


#include <iostream>
#include <flat_map>


int main()
{
std::flat_multimap<int, int> map{{4, 13}, {9, 94}, {1, 19}, {4, 42}};


for (auto it = map.cbegin(); it != map.cend(); ++it)
std::cout << '[' << it->first << "] = " << it->second << '\n';


// Unlike std::multimap's bidirectional iterators, the std::flat_multimap
// iterators are random-access, so they can be used with the operator[]:
auto it = map.cbegin();
assert(it[1] == 19);
assert(it[4] == 13);
assert(it[4] == 42);
assert(it[9] == 94);
}

Output:


[1] = 19
[4] = 13
[4] = 42
[9] = 94
