（c++）类多重继承和派生 - person、student、teacher和graduate类

DescriptionPerson类包含私有成员数据姓名name（string），编号code（int）和出生年月日。Student类包含私有成员数据姓名name（string），编号code（int），出生年月日和分数score（int）。Teacher类包含私有成员数据姓名name（string），编号code（int），出生年月日和所在系department（string）。Graduate类包含私有成员数据姓名name（string），编号code（int），出生年月日，分数score（int）和所在系department（string）。
请根据给定的main函数以及运行结果设计相应的类及相互间的继承关系。
main函数已给定（如下所示），提交时只需要提交main函数外的代码部分。
int main()
{
string name,department;
int Cas=0,code,year,month,day,score;

while(cin>>name>>code>>year>>month>>day>>score>>department)
{
    Cas++;
    cout<<"CASE #"<<Cas<<":"<<endl;
    Person person(name,code,year,month,day);
    Student student(name,code,year,month,day,score);
    Teacher teacher(name,code,year,month,day,department);
    Graduate graduate(name,code,year,month,day,score,department);
    Show(&person);
    Show(&student);
    Show(&teacher);
    Show(&graduate);
}
return 0;

}

Input包含多组数据（数据均正确合法）
每组测试数据1行，分别表示姓名，编号，出生日期，分数和部门。

Output每组测试数据输出具体格式详见Sample Output。
