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

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

Contents

[edit] Parameters

il - an initializer_list

[edit] Return value

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

[edit] Exceptions

(none)

[edit] Notes

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

[edit] 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
