Return reverse iterator to reverse end
Returns a reverse iterator pointing to the theoretical element preceding the first element in the deque container (which is considered its reverse end).
The range between deque::rbegin and deque::rend contains all the elements of the deque container (in reverse order).
A reverse iterator to the reverse end of the sequence container.
If the deque object is const-qualified, the function returns a const_reverse_iterator. Otherwise, it returns a reverse_iterator.
Member types reverse_iterator and const_reverse_iterator are reverse random access iterator types (pointing to an element and to a const element, respectively). See deque member types.
int main ()
std::deque<int> mydeque (5); // 5 default-constructed ints
std::deque<int>::reverse_iterator rit = mydeque.rbegin();
for (rit = mydeque.rbegin(); rit!= mydeque.rend(); ++rit)
*rit = ++i;
std::cout << "mydeque contains:";
for (std::deque<int>::iterator it = mydeque.begin(); it != mydeque.end(); ++it)
std::cout << ' ' << *it;
std::cout << '\n';
The container is accessed (neither the const nor the non-const versions modify the container).
No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.
No-throw guarantee: this member function never throws exceptions.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.
