#include <iostream>


using namespace std;

{

    string m_szName;
    string m_szId;
    int m_nSex;//0:women,1:man

把string 改为char

#include <iostream>
#include <cstring>
using namespace std;
class CPerson

    char *m_szId;

    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<<"职员"<<endl;
