题目描述

1、建立如下的类继承结构：

1)定义一个人员类CPeople，其属性（保护类型）有：姓名、性别、年龄；

2)从CPeople类派生出学生类CStudent，添加属性：学号和入学成绩；

3)从CPeople类再派生出教师类CTeacher，添加属性：职务、部门；

4)从CStudent和CTeacher类共同派生出在职研究生类CGradOnWork，添加属性：研究方向、导师；

2、分别定义以上类的构造函数、输出函数print及其他函数（如需要）。

3、在主函数中定义各种类的对象，并测试之。


输入

第一行：姓名性别年龄

第二行：学号成绩

第三行：职务部门

第四行：研究方向导师

存在多重继承并且继承多个时，在编写最低类的构造函数的时候，需要使用最基类的构造函数进行初始化

在使用多重继承时，保险起见，为所有继承的类使用virtual

注意：这里是virtual，不是volatile

#include "iostream"

using namespace std;

// 1)定义一个人员类 CPeople，其属性（保护类型）有：姓名、性别、年龄；
class CPeople {
protected:
    string name;
    char type;
    int age;
public:
    CPeople() {}

    CPeople(string &name, char type, int age) : name(name), type(type), age(age) {}

    void print() {
        //People:
        // Name: wang-li
        // Sex: m
        // Age: 23
        cout << "People:" << endl;
        cout << "Name: " << name << endl;
        cout << "Sex: " << type << endl;
        cout << "Age: " << age << endl;
    }
};

// 2)从CPeople类派生出学生类 CStudent，添加属性：学号和入学成绩；
class CStudent : virtual public CPeople {
protected:
    string ID;
    double score;
public:

    CStudent() {}

    CStudent(string &name, char type, int age, string &id, double score) : CPeople(name, type, age), ID(id),
                                                                           score(score) {}

    void print() {
        //Student:
        // Name: wang-li
        // Sex: m
        // Age: 23
        // No.: 2012100365
        // Score: 92.5
        cout << "Student:" << endl;
        cout << "Name: " << name << endl;
        cout << "Sex: " << type << endl;
        cout << "Age: " << age << endl;
        cout << "No.: " << ID << endl;
        cout << "Score: " << score << endl;
    }
};

// 3)从CPeople类再派生出教师类 CTeacher，添加属性：职务、部门；
class CTeacher : virtual public CPeople {
protected:
    string work;
    string part;
public:


    CTeacher() {}

    CTeacher(string &name, char type, int age, string &work, string &part) : CPeople(name, type, age),
                                                                             work(work), part(part) {}

    void print() {
        //Teacher:
        // Name: wang-li
        // Sex: m
        // Age: 23
        // Position: assistant
        // Department: computer
        cout << "Teacher:" << endl;
        cout << "Name: " << name << endl;
        cout << "Sex: " << type << endl;
        cout << "Age: " << age << endl;
        cout << "Position: " << work << endl;
        cout << "Department: " << part << endl;
    }
};

// 4)从 CStudent 和 CTeacher类共同派生出在职研究生类 CGradOnWork，添加属性：研究方向、导师；
class CGradOnWork : public CStudent, public CTeacher {
public:
    string searchWay;
    string leader;
