请在下面程序的横线处填上适当内容,以使程序完整,并使程序的输出为:
Name: 龙三
Grade: 19
#include <iostream> #include <string> using namespace std; class Person { public: Person(string s) { name=s; } void display( ) { cout<<"Name: "<<name<<endl; } private: string name; }; class Student:public Person//(1)参考教材P169加底纹部分 { public: Student(string s, int g):Person(s)// (2) { grade=g; } void display1( ) { display(); // (3) cout<<"Grade: "<<grade<<endl; } private: int grade; }; int main( ) { Student s("龙三",19); s.display1(); // (4) return 0; }
项目三
定义一个名为CPerson的类,有以下私有成员:姓名、身份证号、性别和年龄,成员函数:构造函数、输出信息的函数。并在此基础上派生出CEmployee类,派生类CEmployee增加了两个新的数据成员,分别用于表示部门和薪水。要求派生类CEmployee的构造函数显示调用基类CPerson的构造函数,并为派生类CEmployee定义输出信息的函数。
#include<iostream> #include<string> using namespace std; class CPerson { protected: string m_szName; string m_szId; int m_nSex;//0:女,1:男 int m_nAge; public: CPerson(string name,string id,int sex,int age); void Show1(); }; CPerson::CPerson(string name,string id,int sex,int age) { m_szName=name; m_szId=id; m_nSex=sex; m_nAge=age; } void CPerson::Show1() { cout<<m_szName<<" "; cout<<m_szId<<" "; cout<<m_nSex<<" "; cout<<m_nAge<<" "; } class CEmployee:public CPerson { private: string m_szDepartment; double m_Salary; public: CEmployee(string name,string id,int sex,int age,string department,double salary); void Show2(); }; CEmployee::CEmployee(string name,string id,int sex,int age,string department,double salary):CPerson(name,id,sex,age) { m_szDepartment=department; m_Salary=salary; } void CEmployee::Show2() { cout<<"姓名 "<<"ID "<<"性别 "<<"年龄 "<<"部门 "<<"薪水 "<<endl; Show1(); cout<<m_szDepartment<<" "<<m_Salary<<endl; } int main() { string name,id,department; int sex,age; double salary; cout<<"请输入雇员的姓名,ID,性别(0:女,1:男),年龄,部门,薪水:\n"; cin>>name>>id>>sex>>age>>department>>salary; CEmployee employee1(name,id,sex,age,department,salary); employee1.Show2(); return 0; }
