（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
