    正确答案：C
    解析： 此题综合考查了类与对象、循环语句、指针等知识点。在主函数main中，先定义了类Stack的对象s1，通过循环将1、2、3、4压入堆栈内；然后定义对象s2，并用对象s1来初始化，所以s2的大小也是10。第二个循环将4、3弹出并输出，然后将6压入s2的堆栈，然后将s2中剩下的值全部弹出，即6、2、1。

  • 第5题：

    The operation of removing an element from the stack is said to（ ）the stack.

    A.pop
    B.push
    C.store
    D.fetch

    答案：A
    解析：
    从栈中删除一个元素的操作可以称为从栈中取出来。栈（stack）又名堆栈，它是一种运算受限的线性表。其限制是仅允许在表的一端进行插入和删除运算。这一端被称为栈顶，相对地，把另一端称为栈底。向一个栈插入新元素又称作进栈、入栈或压栈，它是把新元素放到栈顶元素的上面，使之成为新的栈顶元素；从一个栈删除元素又称作出栈或退栈，它是把栈顶元素删除掉，使其相邻的元素成为新的栈顶元素。pop stack表示出栈。

  • 第13题：

    请将下列栈类Stack的横线处补充完整。

    class Stack{

    private:

    int pList[100]; ∥int数组，用于存放栈的元素

    int top; ∥栈顶元素(数组下标)

    public:

    Stack():top(0){}

    void Push(const int &item); ∥新元素item


    正确答案：pList[top]=item
    pList[top]=item 解析： 此题考查的是堆栈数据结构。堆栈是一种先进后出的队列，每次入栈在栈顶，出栈也在栈顶。当栈顶指针所指位置是最后一个有效数据时，下次出栈直接取出栈顶指针所指数据，然后栈顶指针再减1；入栈时需要将栈顶指针先增1，然后将数据存入栈顶指针所指位置。本题中，从Pop()数中可以看出，是先取数然后top才会减1，Push()函数应先增1再取数。所以应填入pList[top]=item。
