std::rend(std::initializer_list)

Defined in header <iterator>
template <class E>
std::reverse_iterator<const E*> rend( std::initializer_list<E> il );
(since C++14)

The overload of std::rend for initializer_list returns an std::reverse_iterator pointing at the first element of il.

Parameters

il - an initializer_list

Return value

std::reverse_iterator<const E*>(il.begin()).

Exceptions

(none).

Notes

This overload is necessary because std::initializer_list does not have a member function rend. No overload is needed for std::crend because it is implemented in terms of std::rend.

Example

#include <iostream>
#include <iterator>
 
int main() 
{
    auto il = { 3, 1, 4 };
    for (auto it = std::rbegin(il); it != std::rend(il); ++it)
        std::cout << *it << '\n'; 
}

Output:

4
1
3
