定义以下类：
1个CPerson类，其属性有：姓名、性别和年龄。
2、从CPerson类派生出CStudent类，增加属性：学号、入学时间和入学成绩；
3、从CPerson类派生出CTeacher类，添加属性：职务、部门和工作时间；
4、由CStudent类派生出CGraduate类，添加属性：研究方向和导师；
5、由CGraduate和CTeacher共同派生出在职研究生类CGradonWork；
6、CDate为日期类。
每个类定义一个Print函数，输出其属性值，输出见样例。
主函数里的代码已经给出，请补充完整，提交时请勿包含已经给出的代码。

该回答通过自己思路及引用到GPTᴼᴾᴱᴺᴬᴵ搜索,得到内容具体如下：
以下是完整的代码实现：
#include <iostream>
#include <string>
using namespace std;
class CDate {
public:
CDate(int year, int month, int day) : year_(year), month_(month), day_(day) {}
void Print() {
cout << year_ << "-" << month_ << "-" << day_;
}
private:
int year_;
int month_;
int day_;
};
class CPerson {
public:
CPerson(const string& name, const string& gender, int age)
: name_(name), gender_(gender), age_(age) {}
virtual void Print() {
cout << name_ << " " << age_ << " " << gender_;
}
private:
string name_;
string gender_;
int age_;
};
class CStudent : public CPerson {
public:
CStudent(const string& name, int age, const string& gender,
const string& student_id, const CDate& enroll_date, int enroll_score)
: CPerson(name, gender, age), student_id_(student_id), enroll_date_(enroll_date),
enroll_score_(enroll_score) {}
void Print() {
CPerson::Print();
cout << " " << student_id_ << " ";
enroll_date_.Print();
cout << " " << enroll_score_;
}
private:
string student_id_;
CDate enroll_date_;
int enroll_score_;
};
class CGraduate : public CStudent {
public:
CGraduate(const string& name, int age, const string& gender,
const string& student_id, const CDate& enroll_date, int enroll_score,
const string& research_direction, const string& advisor)
: CStudent(name, age, gender, student_id, enroll_date, enroll_score),
research_direction_(research_direction), advisor_(advisor) {}
void Print() {
CStudent::Print();
cout << " " << research_direction_ << " " << advisor_;
}
private:
string research_direction_;
string advisor_;
};
class CTeacher : public CPerson {
public:
CTeacher(const string& name, int age, const string& gender,
const string& position, const string& department, const CDate& work_date)
: CPerson(name, gender, age), position_(position), department_(department),
work_date_(work_date) {}
void Print() {
CPerson::Print();
cout << " " << position_ << " " << department_ << " ";
work_date_.Print();
}
private:
string position_;
string department_;
CDate work_date_;
};
class CGradOnWork : public CGraduate, public CTeacher {
public:
CGradOnWork(const string& name, int age, const string& gender,
const string& position, const string& department, const CDate& work_date,
const string& student_id, const CDate& enroll_date, int enroll_score,
const string& research_direction, const string& advisor)
: CGraduate(name, age, gender, student_id, enroll_date, enroll_score,
research_direction, advisor),
CTeacher(name, age, gender, position, department, work_date) {}
void Print() {
CGraduate::Print();
cout << " " << CTeacher::position_ << " " << CTeacher::department_ << " ";
CTeacher::work_date_.Print();
cout << endl;
}
};
int main()
{
CGradOnWork s1("crq", 40, "Male", "teacher", "sxxy", CDate(2002, 9, 1),
"15", CDate(2003, 9, 1), 400, "tm", "cs");
s1.Print();
s1.CTeacher::Print();
s1.CGraduate::Print();
s1.CStudent::Print();
s1.CPerson::Print();
return 0;
}
这里使用了多重继承的方式，将 CGraduate 和 CTeacher 共同派生出 CGradOnWork 类。在 CGradOnWork 类中，我们使用了构造函数的初始化列表来初始化 CGraduate 和 CTeacher 的基类，以及自己的数据成员。在 CGradOnWork 类中，我们定义了自己的 Print 函数，并在其中调用了基类的 Print 函数，以输出各个类的属性值。在 main 函数中，我们创建了 CGradOnWork 类的一个对象 s1，并分别调用各个类的 Print 函数，输出各个类的属性值。
