Question

求大神C++人事管理系统程序设计作业帮忙。。。邮箱1228185442@qq.com

有关学校的人事管理情况，作为基类的People（人员）类，具有的属性如下：姓名char name[11],编号char number[7],性别char sex[3], 生日birthday, 身份证号 char id[16], 其中“出生日期”定义为一个“日期”类内嵌对象。
People类派生出Student（学生）类，添加属性：班号 char classNo[7]; 从People类派生出teacher（教师）类, 添加属性：职务char Principalship[11]，部门char department[21]。
从Student类中派生出graduate（研究生）类，添加属性：专业char subject[21]，导师teacher adviser；从graduate类和teacher类派生出TA（助教）类,其中teacher类是从People类派生而来。要求在构造函数中通过键盘实现对各类人员的录入，各类人员都有自己的显示成员函数。按照名字的字母顺序将people类的对象进行排序。注意用虚基类及虚函数。
首先要对类进行分析设计，给出系统的类图。
源程序代码必须要有详细的注释。
要可以执行（C++）
