  • 第1题：

    设链式栈中结点的结构为(data，link)，且top是指向栈顶的指针。若想摘除链式栈的栈顶结点，并将被摘除结点的值保存到x中，则应执行的操作是(32)。

    A．x=top-＞data；top=top-＞link；

    B．top=top-＞link；x=top-＞data；

    C．x=top；top=top-＞link；

    D．x=top-＞data；


    正确答案：A
    解析：x先取栈顶结点的值，并从栈中去掉这个结点。

  • 第3题：

    OSI is a theoretical model that shows how any two different systems can communicate with each other. Router, as a networking device operate at the（）layer of the OSI model

    A.transport
    B.application
    C.network
    D.physical

    答案：C
    解析：
    OSI是Open System Interconnect的缩写，意为开放式系统互联。国际标准组织制定了OSI模型。这个模型把网络通信的工作分为7层，分别是物理层、数据链路层、网络层、传输层、会话层、表示层和应用层。路由器（Router）是运行在OSI中网络层（network）上的网络通信设备，而不是传输层（transport layer）、应用层（application layer）,或物理层（physical layer），因此选C

    A.x=top-＞data；top=top-＞link；
    B.top=top-＞link；x=top-＞data；
    C.x=top；top=top-＞link；
    D.x=top-＞data；

    答案：A
    解析：
    若想摘除链式栈的栈顶节点，并将被摘除节点的值保存到x中，则应执行x=top-＞data；top=top-＞link.
