浙江理工大學信息學院面對對象程序設計實驗報告實驗名稱：類的多態性的實現 學時安排：3實驗類別：設計性實驗 實驗規定：1人1組學號： 姓名：￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣一、實驗目的1.理解重載運算符的意義。2.掌握使用組員函數、友員函數重載運算符的特點。3.掌握重載運算符函數的調用辦法。4.掌握動態聯編的概念。5.掌握虛函數和純虛函數的使用辦法。二、實驗原理介紹設計性實驗具體原理請見實驗內容和環節實現對抽象類的繼承，通過operator函數調用的形式,實現運算符的重載三、實驗設備介紹軟件需求:Windows或Linux下的C++編譯器硬件需求:對于硬件方面的規定，建議配備是PentiumIII450以上的CPU解決器，64MB以上的內存，200MB的自由硬盤空間、CD-ROM驅動器、能支持24位真彩色的顯示卡、彩色顯示屏、打印機。四、實驗內容某公司的員工有經理Manager、技術人員Technicist和營銷人員SalesPerson，他們的薪金計算辦法以下：經理按月計酬，辦法是：基本工資+獎金；技術人員按月計酬，辦法是：基本工資；營銷人員按月計酬，辦法是：基本工資+銷售利潤*5%。每類人員都有職工編號、姓名、性別、入職時間、職位、基本工資等數據；各類人員使用統一接口get_pay()計算各類人員的月薪，重載<<運算符實現員工信息的輸出。另首先，設計一種統計并輸出該公司員工當月薪金狀況的報表類Report，該類提供insert接口向Report類的容器中添加員工信息，并提供print接口用于展示以職位為單位的每個員工的職工編號、姓名、性別、入職時間以及當月該員工的薪酬，并統計出該職位員工薪酬的最高值和最低值。為了提供更方便的查找功效，請為Report類重載[]運算符，下標值為職位，能根據職位信息查找出全部符合該職位的員工。在主函數中對實現的類進行測試，首先，創立各類人員對象，通過Report類的insert接口向報表中添加這些人員信息，然后通過Report類的print接口輸出當月員工薪酬狀況報表。五程序清單#include<iostream>#include<vector>#include<string>usingnamespacestd;classDate{public:inty,m,d;Date(intyy=0,intmm=0,intdd=0):y(yy),m(mm),d(dd){}friendistream&operator>>(istream&is,Date&p);friendostream&operator<<(ostream&os,Date&p);};classEmployee{protected:Datedate;stringemployee_number;stringemployee_name;stringemployee_gender;stringemployee_position;doubleemployee_basic_money;doubleprize[13];public:virtualdoublegetpay(intn)=0;Dateget_date(){returndate;}stringget_number(){returnemployee_number;}stringget_name(){returnemployee_name;}stringget_gender(){returnemployee_gender;}stringget_position(){returnemployee_position;}doubleget_basic_money(){returnemployee_basic_money;}virtualvoidput(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13])=0;};classManager:publicEmployee{public:Manager(inta=0,intb=0,intc=0,doubled=-1){Datedate(a,b,c);employee_basic_money=d;for(inti=0;i<13;i++)prize[i]=0;}voidput(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]);doublegetpay(intn);};classTechnicist:publicEmployee{public:Technicist(intp=-1,inta=0,intb=0,intc=0,intd=-1){Datedate(a,b,c);employee_basic_money=d;}voidput(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]);doublegetpay(intn);};classSalsePerson:publicEmployee{public:SalsePerson(inta=0,intb=0,intc=0,intd=-1){Datedate(a,b,c);for(inti=0;i<13;i++)prize[i]=0;employee_basic_money=d;}voidput(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]);doublegetpay(intn);};classRepoter{private:vector<Employee*>v;vector<Employee*>::iteratorit;public:voidadd(Employee*p);voidprint(intn1,intn2);voidprint(intn);voidoperator[](stringpos);};#include"h1.h"istream&operator>>(istream&is,Date&p){is>>p.y>>p.m>>p.d;returnis;}ostream&operator<<ostream&os,Date&p){os<<p.y<<"/"<<p.m<<"/"<<p.d<<endl;returnos;}voidManager::put(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]){cout<<"M:put"<<endl;date=d;employee_number=e_num;employee_name=e_name;employee_gender=e_g;employee_position=e_p;employee_basic_money=e_m;for(inti=1;i<13;i++)prize[i]=money[i];}doubleManager::getpay(intn){if(employee_basic_money==-1||n>12||n<=0)return-1;returnemployee_basic_money+prize[n];}voidTechnicist::put(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]){cout<<"T:put"<<endl;date=d;employee_number=e_num;employee_name=e_name;employee_gender=e_g;employee_position=e_p;employee_basic_money=e_m;for(inti=1;i<13;i++)prize[i]=money[i];}doubleTechnicist::getpay(intn){returnemployee_basic_money;}voidSalsePerson::put(Dated,stringe_num,stringe_name,stringe_g,stringe_p,doublee_m,doublemoney[13]){cout<<"S:put"<<endl;date=d;employee_number=e_num;employee_name=e_name;employee_gender=e_g;employee_position=e_p;employee_basic_money=e_m;for(inti=1;i<13;i++)prize[i]=money[i];}doubleSalsePerson::getpay(intn){if(employee_basic_money==-1)return-1;returnemployee_basic_money+prize[n]*0.05;}voidRepoter::add(Employee*p){v.push_back(p);}voidRepoter::print(intn1,intn2){inti=0;for(it=v.begin();it!=v.end();it++,i++){cout<<v[i]->get_number()<<endl;cout<<v[i]->get_name()<<endl;cout<<v[i]->get_gender()<<endl;cout<<v[i]->get_date();cout<<v[i]->get_position()<<endl;doublesum=0;for(intj=n1;j<=n2;j++){sum+=v[i]->getpay(j);}cout<<sum<<endl;}}voidRepoter::print(intn){cout<<v[n]->get_number()<<endl;cout<<v[n]->get_name()<<endl;cout<<v[n]->get_gender()<<endl;cout<<v[n]->get_date();cout<<v[n]->get_position()<<endl;cout<<v[n]->get_basic_money()<<endl;}voidRepoter::operator[](stringpos){inti=0;for(it=v.begin();it!=v.end();it++,i++){if(v[i]->get_position()==pos)print(i);cout<<endl;}}#include"h1.h"intmain(){Datedd;stringnumber;stringname;stringgender;stringposition;doublebasic_money;doublemoney[13];Employee*p;Repoterre;//n為真時表達繼續輸入
