请使用VC6或使用【答题】菜单打开考生文件夹proj2下的工程proj2，此工程包含有一个源程序文件proj2．cpp，其中定义了Stack类和ArrayStack类。 Stack是一个用于表示数据结构“栈”的类，栈中的元素是字符型数据。Stack为抽象类，它只定义了栈的用户接口，如下所示： 公有成员函数 功能 push 入栈：在栈顶位置添加一个元素 pop 退栈：取出并返回栈顶元素 ArrayStack是Stack的派生类，它实现了Stack定义的接口。ArrayStack内部使用动态分配的字符数组作为栈元素的存储空间。数据成员maxSize表示的是栈的最大容量，top用于记录栈顶的位置。成员函数push和pop分别实现具体的入栈和退栈操作。 请在程序中的横线处填写适当的代码，然后删除横线，以实现上述功能。此程序的正确输出结果应为： a，b，C C，b，a 注意：只在指定位置编写适当代码，不要改动程序中的其他内容，也不要删除或移动“//****料found****”。 //proj2．cpp includeiostream using namespacc std； class Stack{ public： virtual void push(char C)=0； virtual char pop=0； }；class ArrayStack：public Stack{ char*P； int maxSizc； int top； public： ArravStack（int s） { top=0； maxSize=s： //*********found********* P=______； } ～ArrayStack { //*********found********* _______； } void push(char c) } if(top==maxSize){ cerr”Overflow! \n”： return； } //*********found********* _______； top++： } char pop { if(top==0){ cerr”Underflow!、n”； return‘\0’; } Top--； //*********found********* ______； } }； void f(StacksRef) { char ch[]={‘a’，‘b’，‘c’}； coutch[0]”，”ch[1]”，”ch[2]endl； sRef．push(oh[0])；sRef．push(ch[1])；sRef．push(ch[2])； coutsRef．poP”，”； coutsRef．poP”，”； coutsRef．poPendl； } int main { ArrayStack as(10)； f(as)： return 0： }
使用VC6打开考生文件夹下的工程test34_3。此工程包含一个test34_3.cpp，其中定义了表示栈的类stack。源程序中stack类的定义并不完整，请按要求完成下列操作，将程序补充完整。(1)定义类stack的私有数据成员sp和size,它们分别为整型的指针和变量，其中sP指向存放栈的数据元素的数组，size为栈中存放最后一个元素的下标值。请在注释“//**1**”之后添加适当的语句。(2)完成类stack的构造函数，该函数首先从动态存储空间分配含有100个元素的int型数组，并把该数组的首元素地址赋给指针sp，然后将该数组的所有元素赋值为0，并将size赋值为-1(size等于-1表示栈为空)。请在注释“//**2**”之后添加适当的语句。(3)完成类stack的成员函数push的定义。该函数将传入的整型参数x压入栈中，即在size小于数组的最大下标情况下， size自加1，再给x赋值。请在注释“//**3**”之后添加适当的语句。(4)完成类stack的成员函数pop的定义，该函数返回栈顶元素的值，即在size不等于-1的情况下，返回数组中下标为size的元素的值，并将size减1。请在注释“//**4**”之后添加适当的语句。程序输出结果如下：the top elem：1the pop elem：1the stack is empty注意：除在指定位置添加语句之外，请不要改动程序中的其他内容。源程序文件test34_3.cpp清单如下：include＜iostream.h＞class stack{//** 1 **public:stack ( );bool empty(){return size==-1;}bool full() {return size==99;}void push(int x);void pop();void top();};stack::stack(){//** 2 **for(int i=0; i＜100; i++)*(sp+i)=0;size=-1;}void stack::push(int x){//** 3 **cout＜＜"the stack is full"＜＜end1;else{size++;*(sp+size) = x;}}void stack::pop(){//** 4 **cout＜＜"the stack is empty"＜＜end1;else{cout＜＜"the pop elem:"＜＜*(sp+size)＜＜end1;size--;}}void stack::top(){if iempty() )cout＜＜"the stack is empty"＜＜end1;else{cout＜＜"the top elem:"＜＜*(sp+size)＜＜end1;}}void main ( ){stack s;s.push(1);s.top();s.pop();s.top()；}

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()＜ ＜" ";}
