某小型公司有四类人员：总经理、技术人员、销售经理、推销员。设计一个基类employee， 派生出manager（总经理）、technician（技术人员）、salesmanager（销售经理）、saleman（推销员）。销售经理既是经理又是销售人员，兼具两类人员的特点，因此同时继承manager 和salesman 两个类。 1、类定义 1）employee 类： 基本信息：编号、姓名、性别、出生日期、职位、薪水等； 出生日期使用自定义的 Date（日期）类； 其中：基本信息为 private 属性，成员函数为public 属性； 多个构造函数：缺省构造函数、带参数的构造函数、带默认参数的构造函数； 可以从外部访问类成员的友员函数； 2）Date 类： 成员变量：年、月、日 成员函数：SetYear(int year)、SetMonth(int month)、SetDay(int day) GetYear()、GetMonth()、GetDay() 3）派生类technician：新增属性：工作时间 派生类saleman： 新增属性：销售额、所属部门 2、实现人员信息的录入与显示； 3、计算并显示个人月薪： 月薪计算办法：总经理拿固定月薪8000 元，技术人员按每小时25 元领取月薪；推销员 的月薪按当月销售额的4%提成；销售经理固定月薪5000 元加所管辖部门当月销售总额的5 ‰ 。 附加要求 1、将实验中三不同员工的工资计算函数pay()，用虚函数实现； 2、将每个类中的信息显示函数：display()用虚函数实现； 3、对每个类增加一个升职函数：promote()；
