考题 阅读以下说明C++代码,将应填入(n)处的字句写在对应栏内。[说明]以下程序的功能是实现堆栈的一些基本操作。堆栈类stack共有三个成员函数:empty判断堆栈是否为空;push进行人栈操作;pop进行出栈操作。[C++程序]include "stdafx. h"include <iostream, h>eonst int maxsize = 6;class stack {float data[ maxsize];int top;public:stuck(void);~ stack(void);bool empty(void);void push(float a);float pop(void);};stack: :stack(void){ top =0;cout < < "stack initialized." < < endl;}stack:: ~stack(void) {cout < <" stack destoryed." < < endl;bool stack:: empty (void) {return (1);void stack: :push(float a)if(top= =maxsize) {cout < < "Stack is full!" < < endl;return;data[top] =a;(2);}float stack:: pop (void){ if((3)){cout< < "Stack is undcrflow !" < < endl;return 0;(4);return (5);}void main( ){ stack s;coat < < "now push the data:";for(inti=l;i =maxsize;i+ +) {cout< <i< <" ";s. push(i);}coat < < endl;cout< < "now pop the data:";for(i = 1 ;i < = maxsize ;i + + )cout< <s. pop()< <" ";}

考题 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
