第十一周上机实践项目2——职员有薪水了（2）

（2）字符串除了用C++扩充的string类型外，按C语言的传统，还可以用char 表示。请将类声明中的string全部改为char 后，重新写一遍程序（此时的区别是，类中有指针成员，构造和析构函数需要考虑深复制的问题了。）

代码

#include <iostream>
#include <cstring>
using namespace std;
class CPerson
{
protected:
    char* m_szName;
    char* m_szId;
    int m_nSex;//0:women,1:man
    int m_nAge;
public:
    CPerson(char* name,char* id,int sex,int age);
    void Show1();
    ~CPerson();
};
CPerson::CPerson(char* name,char* id,int sex,int age)
{
    m_szName=new char[strlen(name)+1];
    strcpy(m_szName,name);
    m_szId=new char[strlen(id)+1];
    strcpy(m_szId,id);
    m_nSex=sex;
    m_nAge=age;
}
void CPerson::Show1()
{
    cout<<"姓名："<<m_szName<<endl;
    cout<<"ID："<<m_szId<<endl;
    cout<<"性别：";
    if(m_nSex==0)
        cout<<"女";
    else
        cout<<"男";
    cout<<endl;
    cout<<"年龄："<<m_nAge<<endl;
}
CPerson::~CPerson() {}
class CEmployee:public CPerson
{
private:
    char* m_szDepartment;
    double m_Salary;
public:
    CEmployee(char* name,char* id,int sex,int age,char* department,double salary);
    void Show2();
    ~CEmployee();
};
CEmployee::CEmployee(char* name,char* id,int sex,int age,char* department,double salary):CPerson(name,id,sex,age)
{
    m_szDepartment=new char[strlen(department)+1];
    strcpy(m_szDepartment,department);
    m_Salary=salary;
}
void CEmployee::Show2()
{
    Show1();
    cout<<"部门："<<m_szDepartment<<endl;
    cout<<"薪水："<<m_Salary<<endl;
}
CEmployee::~CEmployee(){}
int main()
{
    char name[10],id[19],department[10];
    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：
