定义Staff（员工）类，由Staff分别派生出Saleman（销售员）类和Manager（经理）类，再由Saleman（销售员）类和Manager（经理）类采用多重继承方式派生出新类SaleMana

要求：

（1）在Staff类中包含的数据成员有编号(num）、姓名(name)、出勤率(rateOfAttend)、基本工资(basicSal)和奖金(prize)。在Saleman类中还包含数据成员销售员提成比例(deductRate)和个人销售额(personAmount)，在Manager类中还包含数据成员经理提成比例(totalDeductRate)和总销售额(totalAmount)。在SaleManager类中不包含其它数据成员。

（2）各类人员的实发工资公式如下：

 

员工实发工资 = 基本工资 + 奖金 * 出勤率

销售员实发工资 = 基本工资 + 奖金 * 出勤率+ 个人销售额 * 销售员提成比例

经理实发工资 = 基本工资 + 奖金 * 出勤率+ 总销售额 * 经理提成比例

销售经理实发工资 =基本工资 + 奖金 * 出勤率+ 个人销售额 * 销售员提成比例+ 总销售额 * 经理提成比例

 

（3）每个类都有构造函数、输出基本信息函数(Output)和输出实发工资函数(OutputWage)。
