先写到这里吧。不知道你是不是学生，为了完成作业，若是，这样可不好哦！

另外，该程序只有简单的查询功能，若想拓展新的功能，如：可实时更新公交车信息，可采用多线程编程，或其他方式。若你是学生的话，慢慢学吧，嘿嘿哟！

哎，刚直看了你的问题，没看到问题下面的要求。
公交车信息的录入，可以在loops函数里增加，要通过判断你从键盘输入了什么内容，比如格式化的命令，如：refresh info bus-id <id> running_state <value>。只是举个例子而已。
另外，也可以采用我上面说的多线程编程，这样更好，但是要主要互斥、加锁的问题。

由于本人是个上班的爷们，要是完成你所要的所有功能，非要写到半夜不可，所以就不给你多弄了，你自己学者弄吧。
