●试题五阅读下列程序说明，将应填入(n)处的字句写在答卷纸的对应栏内。【程序说明】对于一个公司的雇员来说，无非有3种：普通雇员、管理人员和主管。这些雇员有共同的数据：名字、每小时的工资，也有一些共同的操作：数据成员初始化、读雇员的数据成员及计算雇员的工资。但是，他们也有不同。例如，管理人员除有这些共同的特征外，有可能付固定薪水，主管除有管理人员的共同特征外，还有其他物质奖励等。3种雇员中，管理人员可以看作普通雇员的一种，而主管又可以看作管理人员的一种。我们很容易想到使用类继承来实现这个问题：普通雇员作为基类，管理人员类从普通雇员类中派生，而主管人员类又从管理人员类中派生。下面的程序1完成上述各个类的定义，并建立了3个雇员(一个普通雇员、一个管理人员和一个主管)的档案，并打印出各自的工资表。将"程序1"中的成员函数定义为内联函数，pay成员函数定义为虚函数，重新完成上述要求。【程序1】//普通雇员类class Employee{public：Employee(char*theName，float thePayRate)；char*getName()const；float getPayRate()const；float pay(float hoursWorked)const；protected：char*name；//雇员名称float payRate；//薪水等级};Employee::Employee(char*theName，float thePayRate){name=theName；payRate=thePayRate；}char*Employee::getName() const{return name；}float Employee::getPayRate()const{return payRate；}float Employee::pay(float hoursWorked)const{return hoursWorked*payRate；}//管理人员类class Manager∶public Employee{public：//isSalaried付薪方式：true付薪固定工资，false按小时付薪Manager(char*theName，float thePayRate，bool isSalaried)；bool getSalaried()const；float pay(float hoursWorked)const；protected：bool salaried；}；Manager::Manager(char*theName，float thePayRate，bool isSalaried)∶Employee(theName，thePayRate){salaried=isSalaried；}bool Manager::getSalaried() const{return salaried；}float Manager::pay(float hoursWorked)const{if(salaried)return payRate；/*else*/return Employee::pay(hoursWorked)；}//主管人员类class Supervisor：public Employee{public：Supervisor(char*theName，float thePayRate，float theBouns)：Employee(theName，thePayRate， (1) )，bouns(theBouns){}float getBouns()const{return bouns；}float pay(float hoursWorked)constreturn (2) ；}protected：float bouns；}#include"iostream.h"void main(){Employee e("Jack"，50.00)；Manager m("Tom"，8000.00，true)；Supervior s("Tanya"，8000.00，8000.00)；cout"Name:"e.getName()endl；cout"Pay："e.pay(80)endl；//设每月工作80小时cout"Name："m.getName()endl；cout"Pay："m.pay (40) endl；cout"Name："s.getName()endl；cout"Pay："s.pay (40) endl；//参数40在这里不起作用}【程序2】#include"employee.h"//普通雇员类class Employee{public：//构造函数Employee(string theName，float thePayRate)：name(theName)，payRate(thePayRate){}//取雇员姓名string getName() const{returnname；}//取雇员薪水等级float getPayRate()const{return payRate；}//计算雇员薪水virtual float pay(float hoursWorked)const{return (3) ;}protected：string name；//雇员名称float payRate；//薪水等级};//管理人员类//继承普通雇员类class Manager：public Employee{public：//构造函数//isSalaried标识管理人员类的付薪方式//true 按阶段付薪(固定工资)//false按小时付薪Manager(string theName，float thePayRate，bool isSalaried)：Employee(theName，thePayRate)，salaried(isSalaried){}//取付薪方式bool getSalaried()const{return salaried；}//计算薪水virtual float pay(float (4) )const；protected：bool salaried；}；float Manager::pay(float hoursWorked)const{if(salaried)//固定付薪方式return payRate；else//按小时付薪return (5) ； }//主管人员类class Supervisor： (6){public：//构造函数Supervisor(string theName，float thePayRate，float theBouns)：Manager(theName，thePayRate，true)，bouns(theBouns){}//取奖金数额float getBouns()const{return bouns；}//计算薪水virtual float pay(float hoursWorked)const{retum payRate+bouns；}(7)float bouns；}#include"employee.h"#include"iostream.h"void main(){(8) *ep[3]；ep[0]=new Employee("Jack"，"50.00")；ep[1]=new Manager("Tom"，"8000.00"，true)；ep[2]=new Supervior("Tanya"，"8000.00"，"8000.00")；for(int i=0；i3;i++){cout"Name：" (9) endl；cout"Pay：" (10) endl；//设每月工作80小时}}
