双向队列rbegin函数运用实例

rbegin
语法:

1	reverse_iterator rbegin();

rbegin()返回一个指向双向队列尾部的逆向迭代器。

源代码

/**

* Returns a read/write reverse iterator that points to the last element

* in the %deque. Iteration is done in reverse element order.

reverse_iterator

rbegin()

{ return reverse_iterator(this->_M_impl._M_finish); }

/**

* Returns a read-only (constant) reverse iterator that points to the

* last element in the %deque. Iteration is done in reverse element

* order.

const_reverse_iterator

rbegin() const

{ return const_reverse_iterator(this->_M_impl._M_finish); }
