程序的输出结果如下：

Parent:: Parent( ) called.

Child:: Child( ) called.

Child:: ~Called( ) called.

Parent:: ~Parent( ) called.

根据输出结果在下面程序中的下划线出填写正确的语句

include ﹤iostream﹥

using namespace std;

class Parent

{

public:

Parent( ) { cout ﹤﹤"Parent:: Parent( ) called. \n"; }

vintual ~Parent( ) { cout ﹤﹤"Parent:: ~Parent( ) called. \n"; }

}:

class Child: public Parent

{

public:

Child(int i) {

cout﹤﹤"Child:: Child( ) called. \n";

buf=new char[i];

}

virtual ~Child( ) {

delete [ ]buf;

cout﹤﹤"Child:: ~Child( ) called. \n";

}

private:

char * buf;

};

void disp( _________ *a)

{

_________;

}

woid main( )

{

Parent *a=new Child(20);

disp(a);

int d;

cin ﹥﹥d;

}

定义堆栈类模板Stack(先进后出)，栈的大小由使用者确定。要求该类模板对外提供如下二种基本操作：

(1)push入找

(2)pop出栈，用数组来实现

#include ﹤iostream﹥

using namespace std;

template﹤class T, int size﹥

class Stack {

T x[size];

int current;

public:

Stack( ) { current =0; }

....push(....);

....pop(....);

}

请写出两个函数的过程(如果需要形式参数，请给出形参类型和数量，以及返回值类型)

给出下面程序的输出结果

#include ﹤iostream﹥

using namespace std;

class Simple

{

int x, y;

public:

Simple( ) { x=y=0; }

Simple( int i, int j) { x=i; y =j; }

void copy( Simple &s);

void setxy { int i, int j) { x=i; y=j; }

void print( ) { cout ﹤﹤"x="﹤﹤x﹤﹤",y="﹤﹤y ﹤﹤ endl; }

};

void Simple:: copy( Simple &s)

{

x=s.x; y=s.y;

}

void func ( Simple s1, Simple &s2)

{

s1. setxy(30, 40);

s2. setxy(70, 80);

}

vpid main( )

{

Simple obj1(1, 2), obj2;

obj2. copy(obj1);

func(obj1, obj2);

obj1. print( );

obj2. print( );

}

请写出myText1. txt文本文件中的内容

#include ﹤iostream﹥

#include ﹤string﹥

using namespace std;

#include ﹤fstream﹥

void main( )

{

ofstream myFile1;

myFile1. open("myText1. txt");

cout﹤﹤"Enter the data in Chinese format(e. g. , 2008, May 25): "﹤ endl;　　string Date("2008, January 1");

string Year=Date. substr(0,4);

int k=Date. find( ",");

int i= Date. find(" ");

string Month= Date. substr(k+1, i-k-1);

tring Day = Date. substr(i+1, 2);

string NewDate=Day +" "+Month+" "+Year;

myFile1﹤﹤"original date: "﹤﹤ Date ﹤﹤ endl;

myFile1﹤﹤"Converted date: "﹤﹤NewDate ﹤﹤ endl;

myFile1. close( );

}

在下面下划线处填上正确的语句使序输出结果为　　201　　402　　3　　4　　5

#include ﹤iostream﹥

using namespace std;

template ﹤class T﹥

T f(T &a, T &b, int n) {

for(int i=0; i﹤n; i++) {

a[i]=a[i]+b[i];

}

return a;

}

void main( ) {

int a[5]={1,2,3,4,5};

int b[5]={100,200,300,400,500}, *p;

for(int i=0; i﹤2; i++) {

p=_________;

}

for( ; p﹤a+5; p++){

cout ﹤﹤_________﹤﹤endl;

}

}

完成下面类的定义，使其可以正确的初始化成员变量m和n：

class point {

private: int m, n;

public:

point( int, int);

point(point &t);

};

point:: point(int a, int b) {

m=a;　　_________=b;

}

point:: point( _________ ) {

m=t. m;

n=t. n;

}

在下面横线处填上适当的语句完成类的定义。

#include ﹤iostream﹥

using namespace std;

class Base {

int x;

static const int b;

public:

Base (int, int);

const int *a;

};

_________ b=15;

Base:: Base( int i, int j): _________ { }

输入一个字符串，将其逆序输出：

#include ﹤iostream﹥

using namespace std;

void main( ) {

char a[50];

memset(a, 0, sizeof(a));

int i=0, j;

char t;

cin. getline( a, 50, '\n');

for(i=0, j=_________; i﹤_________; i++, j--) {

t=a[i];

a[i]=a[j];

a[j]=t;

}

cout ﹤﹤a﹤﹤ endl;

}

程序的输出结果如下：

Parent:: Parent( ) called.

Child:: Child( ) called.

Child:: ~Called( ) called.

Parent:: ~Parent( ) called.

根据输出结果在下面程序中的下划线出填写正确的语句

include ﹤iostream﹥

using namespace std;

class Parent

{

public:

Parent( ) { cout ﹤﹤"Parent:: Parent( ) called. \n"; }

vintual ~Parent( ) { cout ﹤﹤"Parent:: ~Parent( ) called. \n"; }

}:

class Child: public Parent

{

public:

Child(int i) {

cout﹤﹤"Child:: Child( ) called. \n";

buf=new char[i];

}

virtual ~Child( ) {

delete [ ]buf;

cout﹤﹤"Child:: ~Child( ) called. \n";

}

private:

char * buf;

};

void disp( _________ *a)

{

_________;

}

woid main( )

{

Parent *a=new Child(20);

disp(a);

int d;

cin ﹥﹥d;

}

#include ﹤iostream.h﹥

main( ) {

int x=5, y=6;

const int *p=&x;

*p=y;

cout﹤﹤*p﹤﹤endl;

}

#include ﹤iostream﹥

using namespace std;

main( ) {

int num;

max=10;

num=1;

while( num﹤max) num++;

cout ﹤﹤"num="﹤﹤num;

}
