编写一个学生和教师数据输入和显示程序，学生数据有编号、姓名、班号和成绩，教师数据有编号、姓名、职称和部门。要求将编号、姓名输入和显示设计成一个类person,并作为学生数据操作类student和教师数据操作类teacher的基类。

#include <iostream>#include <string> using namespace std; class person {private:int no; string name; public:void input(){cout<<"请输入编号和姓名:";cin>>no>>name;} void display() {cout<<"编号： "<<no<<endl;cout<<"姓名："<<name<<endl;} }; class student:public person {private:int bh;int score; public: void get()  {         input();  cout<< "请输入班号和成绩:";         cin>>bh>>score;}  void show() { display(); cout<<"班号:"<<bh<<endl;  cout<<"成绩: "<<score<<endl;} }; class teacher:public person  { private: string title,department; public:  void get() { input(); cout<< "请输入职称和部门:"; cin>>title>>department;}  void show( )  { display(); cout<<"职称:"<<title<<endl;       cout<<"部门:"<<department<<endl;}  }; int main( )  { student s; teacher t;  s.get( ); s.show( ); t.get( ); t.show( ); return 0; }

设计一个虚基类base,包括姓名和年龄私有数据成员以及相关的成员函数；由它派生出领导类leader，包含职务和部门私有数据成员以及相关的成员函数；再由base派生出工程师类engieer，包含职称和专业私有数据成员以及相关的成员函数；然后由leader和engieer，派生出主任工程师类chairman.采用相关数据进行测试。

#include<iostream>#include<string>using namespace std;class base {public: base(string name1,int age1) {name=name1;age=age1; }void print(){cout<<"姓名:"<<name<<endl;cout<<"年龄:"<<age<<endl;}protected:string name;int age;};class leader:virtual public base {public:leader(string name1,int age1,string job1,string dep1):base(name1,age1)  {job=job1;   dep=dep1;}  void print()  {  base::print();  cout<<"职务:"<<job<<endl;  cout<<"部门:"<<dep<<endl;  }protected:string job;string dep;};class engineer:virtual public base {public:engineer(string name1,int age1,string prof1,string major1):base(name1,age1)  {prof=prof1;   major=major1;  }  void print()  {  base::print();  cout<<"职称:"<<prof<<endl;  cout<<"专业:"<<major<<endl;  }protected:string prof;string major;};class chairman:public leader,public engineer {chairman(string name1,int age1,string job1,string dep1,string prof1,string major1):base(name1,age1),leader(name1,age1,job1,dep1),engineer(name1,age1,prof1,major1){;}   void print()  {leader::print();engineer::print();  }};void main(){chairman my_chairman("lili","22","laoshi","jiaowuchu","gaojijiaoshi","huaxue");my_chairman.print();}
