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：
