第11周 项目二-职员有薪水了（1）

（1）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、析构函数、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定义析构函数，定义输出信息的函数。

class CPerson{protected:    string m_szName;    string m_szId;    int m_nSex;//0:women,1:man    int m_nAge;public:    CPerson(string name,string id,int sex,int age);    void Show1();    ~CPerson();};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();};int main(){    string name,id,department;    int sex,age;    double salary;    cout<<"input employee's name,id,sex(0:women,1:man),age,department,salary:\n";    cin>>name>>id>>sex>>age>>department>>salary;    CEmployee employee1(name,id,sex,age,department,salary);    employee1.Show2();    return 0;}

下面的运行结果供参考：

代码

#include <iostream>#include <cstring>#include <iomanip>using namespace std;class CPerson{protected:    string m_szName;    string m_szId;    int m_nSex;//0:women,1:man    int m_nAge;public:    CPerson(string name,string id,int sex,int age);    void Show1();    ~CPerson();};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();};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<<setw(5)<<m_szName<<setw(18)<<m_szId;    if(m_nSex==0)        cout<<setw(7)<<"women";    else cout<<setw(7)<<"man";    cout<<setw(8)<<m_nAge;}CPerson::~CPerson() {}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<<setw(5)<<"name"<<setw(18)<<"id"<<setw(7)<<"sex"<<setw(8)<<"age"<<setw(12)<<"department"<<setw(10)<<"salary"<<endl;    Show1();    cout<<setw(12)<<m_szDepartment<<setw(10)<<m_Salary;}int main(){    string name,id,department;    int sex,age;    double salary;    cout<<"input employee's name,id,sex(0:women,1:man),age,department,salary:\n";    cin>>name>>id>>sex>>age>>department>>salary;    CEmployee employee1(name,id,sex,age,department,salary);    employee1.Show2();    return 0;}

运行结果：

知识点总结：

<iomanip>  setw(10)用于对齐
