# std::end

From cppreference.com
< cpp‎ | iterator

Defined in header `<iterator>` |  |
template< class C > auto end( C& c ) -> decltype(c.end()); | (1) | (since C++11)
template< class C > auto end( const C& c ) -> decltype(c.end()); | (1) | (since C++11)
template< class T, size_t N > T* end( T (&array)[N] ); | (2) | (since C++11)
template< class C > auto cend( const C& c ) -> decltype(std::end(c)); | (3) | (since C++14)

Returns an iterator to the end (i.e. the element after the last element) of the given container `c` or array `array`.

1) Returns a possibly const-qualified iterator to the end of the container `c`.
2) Returns a pointer to the end of the array `array`.
3) Returns a const-qualified iterator to the end of the container `c`.

### [edit] Parameters

c | - | a container with an `end` method
array | - | an array of arbitrary type

### [edit] Return value

An iterator to the end of `c` or `array`. Note that the end of a container or array is defined as the element following the last valid element.

### [edit] Notes

In addition to being included in `<iterator>`, `std::end` is guaranteed to become available if any of the following headers are included: `<array>`, `<deque>`, `<forward_list>`, `<list>`, `<map>`, `<regex>`, `<set>`, `<string>`, `<unordered_map>`, `<unordered_set>`, and `<vector>`.

### [edit] Specializations

Custom specializations of `std::end` may be provided for classes that do not expose a suitable `end()` member function, yet can be iterated. The following specializations are already provided by the standard library:

std::end(std::initializer_list) (C++11) | specializes std::end (function template) [edit]
std::end(std::valarray) (C++11) | specializes std::end (function template) [edit]

### [edit] Example

Run this code

    #include <iostream>
    #include <vector>
    #include <iterator>
    #include <algorithm>

    int main()
    {
        std::vector<int> v = { 3, 1, 4 };
        if (std::find(std::begin(v), std::end(v), 5) != std::end(v)) {
            std::cout << "found a 5 in vector v!\n";
        }

        int a[] = { 5, 10, 15 };
        if (std::find(std::begin(a), std::end(a), 5) != std::end(a)) {
            std::cout << "found a 5 in array a!\n";
        }
    }

Output:

    found a 5 in array a!
