题目描述
在习题4-3的基础上，Person类添加日期类对象作数据成员，由Person类公有派生出Student类和Teacher类，由Student类和Teacher类公有派生子类TA（助教博士生）类，添加数据成员：专业（string类型），添加构造函数、输出函数（输出一个TA对象的全部信息）。注意虚基类的使用。类之间的关系如图4-1所示（电子文档中）。
主函数中定义一个TA类对象，其各数据成员的初始值由键盘输入，输出TA类对象的全部信息；修改TA对象的出生年月日，数据由键盘输入（按年月日顺序），再输出TA类对象的全部信息。
输入描述
一个TA类对象的全部信息
修改的出生年月日信息
输出描述
修改前TA类对象的全部信息
修改后TA类对象的全部信息
