reverse_iterator::operator*


public member function
reference operator* () const;

Dereference iterator

Returns a reference to the element pointed by the iterator.

The iterator must point to some object (must not be null pointing) in order to be dereferenciable.

Parameters

none

Return value

A reference to the element pointed by the iterator.
reference is a member type defined as an alias of the base iterator's own reference type.

  for ( ; rev_iterator < rev_end ; ++rev_iterator)
    cout << *rev_iterator << " ";
  cout << endl;

  return 0;
}


Output:

9 8 7 6 5 4 3 2 1 0
