编写一个程序实现顺序队列的各种基本运算,并在此基础上设计一个主程序完成如下功能： 1．　　初始化队列q。 2．　　判断队列q是否为空。 3．　　依次进队元素a,b,c。 4．　　出队一个元素，输出该元素。 5．　　输出队列q的元素个数。 6．　　依次进队列元素d,e,f。 7．　　输出队列q的元素个数。 8．　　输出出队序列。 9．　　释放队列。-Write a program to achieve a variety of basic operations of the order queue, and based on the design of a main program performs the following functions: 1. Initialize the queue q. 2. Q is determined whether the queue is empty. 3. Turn into the team elements a, b, c. 4. Dequeue an element, the output of the element. 5. Q the number of elements in the output queue. 6. Turn into a queue element d, e, f. 7. Q the number of elements in the output queue. 8. Sequence output　the team. 9. Release queue.
