*完成日期:2014 年 5 月 26 日
*版本号:v1.0
*对任务及求解方法的描述部分:
*输入描述:num,name,sex,year,month,day 和修改后的year,month,day
*问题描述: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

*程序输出:        Sample Input
                   2001 Huang m
                   1970 1 1
                   1994 5 26
				   Sample Output
                   num:2001
                   name:Huang
                   sex:m
                   birthday:1994/5/26
