C++类的组合编程问题求帮忙

设计出生日期类birthday:
year,month,day
设计学生类student:
No(学号) ,Name(姓名),Birth(生日),Score(成绩)
下面是主函数部分
int main()
{
Birthday d(2002,1,1);
Student s1;
Student
s2("102","AAA",98,2001,1,1);
s1.disp();
s2.disp();
Student
s3("103","BBB",90,d);
s3.disp();
return 0;
}

帮忙添加两个类,再用类的组合实现并完善一下这个程序~初学者求解,谢谢
