【TOJ 5253】C++实验：多继承

描述

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。

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;
