public member function

std::array::crbegin

<array>
const_iterator crbegin() const noexcept;
Return const_reverse_iterator to reverse beginning
Returns a const_reverse_iterator pointing to the last element in the array container.

A const_reverse_iterator is an iterator that points to const content and iterates in reverse order. This iterator can be increased and decreased (unless it is itself also const), just like the iterator returned by array::rbegin, but it cannot be used to modify the contents it points to.

Parameters

none

Return Value

A const_reverse_iterator to the beginning of the sequence.

Member type const_reverse_iterator is a random access iterator type, defined in array as reverse_iterator<iterator> and reverse_iterator<const_iterator> respectively.

// array::rbegin/rend
#include <iostream>
#include <array>

int main ()
{
  std::array<int,6> myarray = {10, 20, 30, 40, 50, 60} ;

  std::cout << "myarray contains:";
  for ( auto rit=myarray.crbegin() ; rit < myarray.crend(); ++rit )
    std::cout << " " << *rit;   // cannot modify *rit

  std::cout << std::endl;

  return 0;
}


Output:
myarray contains: 60 50 40 30 20 10

Complexity

Constant.
