C++ - Exercise12实验报告

3.源代码

#include using namespace std;

class building {

private:

int Floor; //楼房层数 int House_num; //房间数 double Build_area; //建筑面积 public:

void Init(int floor,int num,double area); int GetFloor(){return Floor;} int GetNum(){return House_num;}

double GetArea(){return Build_area;} void show(); };

class housing:public building {

private:

int Bedroom; //卧室数量 int Bathroom; //浴室数量 public:

void Init1(int floor,int num,double area,int bed,int bath); int GetBed(){return Bedroom;} int Getbath(){return Bathroom;} void display1(); };

class officebuilding:public building {

private:

int Extinguisher; //灭火器数量 int Tel; //电话数量 public:

void Init2(int floor,int num,double area,int exti,int tel); int GetExti(){return Extinguisher;} int GetTel(){return Tel;}

void display2();

};

void building::Init(int floor,int num,double area) {

Floor=floor; House_num=num; Build_area=area; }

void building::show() {

cout<<\楼房层数:\cout<<\房间数:\cout<<\建筑面积:\}

void housing::Init1(int floor,int num,double area,int bed,int bath) {

Init(floor,num,area); Bedroom=bed; Bathroom=bath; }

void housing::display1() {

show();

cout<<\卧室数量:\cout<<\浴室数量:\}

void officebuilding::Init2(int floor,int num,double area,int exti,int tel) {

Init(floor,num,area); Extinguisher=exti; Tel=tel; }

void officebuilding::display2() {

show();

cout<<\灭火器数量:\cout<<\电话数量:\}

void main() {

housing hou;

hou.Init1(20,450,36000,300,300); officebuilding off;

off.Init2(10,150,18000,80,160); hou.display1(); cout<

off.display2(); }

4.源代码

#include using namespace std;

class Clock {

private: int Hour; int Minute; int Second; public:

void SetTime(int h=0,int m=0,int s=0)//设置时间 {

Hour=h; Minute=m; Second=s; }

void ShowTime() //显示时间 {

cout<

class AlermClock:public Clock {

private:

int AlermHour; int AlermMinute; int AlermSecond; public:

void Alerm() // 转义字符'\\a'完成响铃

{

cout << \}

void SetAlermTime(int h,int m,int s) {

AlermHour=h; AlermMinute=m; AlermSecond=s; }

void ShowAlermTime() {

cout<

void main() {

AlermClock c;

c.SetTime(15,59,30); cout<<\设置时间:\c.ShowTime();

c.SetAlermTime(6,30,0); cout<<\响铃时间:\c.ShowAlermTime(); c.Alerm(); }

三、结论

1、实验结果

直接见过程

2、分析讨论

(1)什么时候该用public继承，什么时候用private继承，或protected继承？ 这三类继承本质区别是？有什么方法更好理解它们
