[YTU]_2476(C++习题 继承与组合)

题目描述

已知类如下：

（1） BirthDate（生日类） 含有：year,month,day 等数据成员

（2） Teacher（教师类）含有：num,name,sex 等数据成员

（3） Professor（教授类）含有：教师类和生日类的数据成员

要求：

（1）通过对Teacher和BirthDate使用继承和组合的方式设计Professor

（2）定义Professor类对象prof，并给出所有数据的初值

（3）修改prof的生日数据

（4）输出prof的全部最新数据

输入

 num,name,sex,year,month,day 和修改后的year,month,day

输出

 num,name,sex,year,month,day 

样例输入

2001 Huang m
1970 1 1
1994 5 26

样例输出

num:2001
name:Huang
sex:m
birthday:1994/5/26
