实验4 继承与派生-程序

实验4 继承与派生---参考程序

二、实验内容

1．定义一个基类有姓名、性别、年龄，再由基类派生出教师类和学生类，教师类增加工号、职称和工资，学生类增加学号、班级、专业和入学成绩。

#include

#include

using namespace std;

class Person

{

public:

Person(string s1,int s2,string s3): name(s1),age(s2),gender(s3){}

void show()

{ cout<

private:

string name;

int age;

string gender;

};

class Teacher: public Person

{

public:

Teacher(string s1,int s2,string s3,string s4,string s5,double s6):Person(s1,s2,s3),num(s4),title(s5),salary(s6){}

void show()

{// Person::show();

cout<

private:

string num;

string title;

double salary;

};

class Student:public Person{

public:

Student(string s1,int s2,string s3,string s4,string s5,string s6,double s7):

Person(s1,s2,s3),num(s4),Class(s5),major(s6),score(s7){}

void show()

{ Person::show();

cout<

string num;

string Class;

string major;

double score;

};

int main(void)

{

Teacher T("JSR",34,"female","23435","professor",10000);

Student S("ZJ",19,"male","36","BX1108","Communication",88);

cout<<"姓名"<<"\t"<<"年龄"<<"\t"<<"性别"<<"\t"<<"工号"<<"\t"<<"职称"<<"\t\t"<<"薪水"<

T.Person::show();

T.show();

cout<<"姓名"<<"\t"<<"年龄"<<"\t"<<"性别"<<"\t"<<"学号"<<"\t"<<"班级"<<"\t\t"<<"专业"<<"\t"<<"成绩"<

S.show();

return 0;

}

2．设计一个圆类Circle和一个桌子类Table，再由它们共同派生出圆桌类RoundTable，要求输出一个圆桌的高度、面积和颜色等数据。

#include

#include

using namespace std;

class Circle

{

public:

Circle(double r):radius(r){}

double area()

{return 3.14159*radius*radius;}

private:

double radius;

};

class Table

{

public:

Table(string c,double h):color(c),height(h){}

void show()

{ cout<<"The Table's color is "<

private:

string color;

double height;

};

class Roundtable: public Circle,public Table

{

public:

Roundtable(double r,string c,double h):Circle(r),Table(c,h){}

};

int main(void)

{

Roundtable R(4,"blue",3);

R.show();

cout<<" ,area is "<

return 0;

}

3. 分别定义教师类Teacher和干部类Cadre，采用多重继承的方式由这两个类派生出新类Teacher_Cadre（教师兼干部类）。要求：

#include

#include

using namespace std;

class Teacher

{public:

Teacher(string nam, int a, char s, string tit, string ad, string t);

void display();

protected:

string name; //姓名

int age; //年龄

char sex; //性别

string title; //职称

string addr; //地址

string tel; //电话

};

Teacher::Teacher(string nam, int a, char s, string tit, string ad, string t): name(nam), age(a), sex(s), title(tit), addr(ad), tel(t){ }

void Teacher::display()

{ cout << "name:" << name << endl;

cout << "age:" << age << endl;

cout << "sex:" << sex << endl;

cout << "title:" << title << endl;

cout << "address:" << addr << endl;

cout << "tel:" << tel << endl;

}

class Cadre

{public:

Cadre(string nam, int a, char s, string p, string ad, string t);

void display();

protected:

string name; //姓名

int age; //年龄
