std::rend(std::initializer_list): std::rend(std::initializer_list)

NAME

std::rend(std::initializer_list) - std::rend(std::initializer_list)

Synopsis

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

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

// Run this code

  #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
