/*DescriptionStudent类含有私有数据成员:num,name,sex，公有成员函数: 输入函数get_value()和输出函数display()。采用私有继承方式实现类Student1，增加数据成员:age,addr，成员函数:get_value_1()和display_1()。在程序运行时输入num,name,sex,age,addr的值，调用输出函数输出以上5个数据的值。Input输入num,name,sex,age,addr的值Output输出num,name,sex,age,addr的值Sample Input1001 zhang m 21 shanghaiSample Outputnum: 1001name: zhangsex: mage: 21address: shanghai*/#include <iostream>using namespace std;class Student{public:    void get_value()    {        cin>>num>>name>>sex;    }    void display( )    {        cout<<"num: "<<num<<endl;        cout<<"name: "<<name<<endl;        cout<<"sex: "<<sex<<endl;    }private :    int num;    string name;    char sex;};class Student1:private Student{public:    void get_value_1()    {        get_value();        cin>>age>>addr;    }    void display_1()    {        display( );        cout<<"age: "<<age<<endl;        cout<<"address: "<<addr<<endl;    }private:    int age;    string addr;};int main(){    Student1 stud1;    stud1.get_value_1();    stud1.display_1();    return 0;}
