习题
1.将例11.1的程序片段补充和改写成一个完整、正确的程序，用公有继承方式。在程序中应包括输入数据的函数，在程序运行时输入num,name,sex,age,addr的值，程序应输出以上5个数据的值。#include<iostream>
#include<string>
usingnamespacestd;
classStudent
{public:
voidget_value()
{cout<<"pleaseinputnum,name,sex:";
cin>>num>>name>>sex;}
voiddisplay()
{cout<<"num:"<<num<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl;}
private:
intnum;stringname;charsex;
};classStudent1:publicStudent
{public:
voidget_value1()
{get_value();
cout<<"pleaseinputage,address:";
cin>>age>>addr;}
voiddisplay_1()
{display();
cout<<"age:"<<age<<endl;
cout<<"address:"<<addr<<endl;}
private:
intage;
stringaddr;
};intmain()
{Student1stud;
stud.get_value1();
stud.display_1();
return0;
}2.将例11.2的程序片段补充和改写成一个完整、正确的程序，用私有继承方式。在程序中应包括输入数据的函数，在程序运行时输入num,name,sex,age,addr的值，程序应输出以上5个数据的值。#include<iostream>
#include<string>
usingnamespacestd;
classStudent
{public:
voidget_value()
{cout<<"pleaseinputnum,name,sex:";
cin>>num>>name>>sex;}
voiddisplay()
{cout<<"num:"<<num<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl;}
private:
intnum;stringname;charsex;
};classStudent1:privateStudent
{public:
voidget_value1()
{get_value();
cout<<"pleaseinputage,address:";
cin>>age>>addr;}
voiddisplay_1()
{display();
cout<<"age:"<<age<<endl;
cout<<"address:"<<addr<<endl;}
private:
intage;
stringaddr;
};intmain()
{Student1stud;
stud.get_value1();
stud.display_1();
return0;
}3.将例11.3的程序修改、补充，写成一个完整、正确的程序，用保护继承方式。在程序中应包括输入数据的函数。#include<iostream>
#include<string>
usingnamespacestd;
classStudent
{public:
voidget_value()
{cout<<"pleaseinputnum,name,sex:";
cin>>num>>name>>sex;}
voiddisplay()
{cout<<"num:"<<num<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl;}
protected:
intnum;stringname;charsex;
};classStudent1:protectedStudent
{public:
voidget_value1()
{cout<<"pleaseinputnum,name,
sex,age,addr:"<<endl;
cin>>num>>name>>sex>>age>>addr;}
voiddisplay_1()
{display();
cout<<"age:"<<age<<endl;
cout<<"address:"<<addr<<endl;}
private:

stringaddr;
};intmain()
