一道软件实习的题目

 

4． 某工厂有一名老板Boss，及若干工人。工人分为小时工HourlyWorker、计件工PieceWorker、销售员CommissionWorker。小时工每周工作40小时，超过40小时部分的报酬是平时的1.5倍；计件工是按生产的工件计算报酬的，每件的报酬是固定的，假设他只生产一种类型的工件；销售员每周有小部分固定的基本工资加上每周销售额的固定百分比；老板每周有固定的薪水。为该工厂设计一个简单的工资管理信息系统。要求如下：

（1）设计实现一个简单的类Employee，它存储雇员的工号、姓（成员firstName）和名（成员lastName）。从雇员类Employee派生出小时工类HourlyWorker、计件工类PieceWorker、销售员类CommissionWorker及老板类Boss。

（2）用Employee指针数组指向工厂的所有员工对象。

（3）可以增加一名工人。增加工人时，根据工人的类别，输入相应的信息。如增加的是小时工，则需要输入该小时工的工号、姓、名、本周工作小时数及每小时工资额等信息。

(4) 可以输入所有员工信息

（5）可以根据工号删除一名工人

（6）可以根据工号修改工人的信息

（7）可以显示出所有员工的本周工资信息

（8）显示出一些统计信息，如本周支付所有员工的工资总额；小时工的工资总额、最高、最低、平均工资；计件工的工资总额、最高、最低、平均工资；销售员的工资总额、最高、最低、平均工资
