public member function

std::vector::crend

<vector>
const_reverse_iterator crend() const noexcept;
Return const_reverse_iterator to reverse end
Returns a const_reverse_iterator pointing to the element right before the first element in the container (which is considered its reverse end).

Parameters

none

Return Value

A const_reverse_iterator to the reverse beginning of the sequence.

Member type const_reverse_iterator is a reverse random access iterator type.

// vector::crbegin/crend
#include <iostream>
#include <vector>

int main ()
{
  std::vector<int> myvector = {1,2,3,4,5};

  std::cout << "myvector backwards:";
  for (auto rit = myvector.crbegin(); rit != myvector.crend(); ++rit)
    std::cout << ' ' << *rit;
  std::cout << '\n';

  return 0;
}


Output:
myvector backwards: 5 4 3 2 1

Complexity

Constant.

Iterator validity

No changes.

Data races

The container is accessed.
No contained elements are accessed by the call. Concurrently accessing or modifying them is safe.
