第十周任务二

#include <iostream>#include <string.h>#include <iomanip>//setw:设置输出数据的宽度,使用时应#include <iomanip.h> using namespace std;class CPerson {protected:char *m_szName;char *m_szId;int m_nSex;//0:women,1:manint m_nAge;public:CPerson(char *name,char *id,int sex,int age);void Show1();~CPerson(); //需要释放建立对象时动态分配的内存};class CEmployee:public CPerson{private:char *m_szDepartment;float m_Salary;public:CEmployee(char *name,char *id,int sex,int age,char *department,float salary);void Show2();~CEmployee();};CPerson::CPerson(char *name,char *id,int sex,int age):m_nSex(sex),m_nAge(age){m_szName=new char [strlen(name) + 1]; strcpy(m_szName,name);m_szId=new char [strlen(id) + 1];strcpy(m_szId,id);}CPerson::~CPerson(){delete [] m_szName;delete [] m_szId;}void CPerson::Show1(){cout<<setw(10)<<m_szName<<setw(25)<<m_szId<<setw(7);if(m_nSex==0){cout<<"women";}else if(m_nSex==1){cout<<"men";}cout<<setw(5)<<m_nAge;}CEmployee::CEmployee(char *name,char *id,int sex,int age,char *department,float salary):CPerson(name,id,sex,age){m_szDepartment=new char[strlen(department)+1];      strcpy(m_szDepartment,department);      m_Salary=salary;  }void CEmployee::Show2(){cout<<setw(10)<<"name"<<setw(25)<<"id"<<setw(7)<<"sex"<<setw(5)<<"age"<<setw(12)<<"department"<<setw(10)<<"salary"<<endl; Show1(); cout<<setw(12)<<m_szDepartment<<setw(10)<<m_Salary<<endl;}CEmployee::~CEmployee(){delete [] m_szDepartment;}int main(){char name[10],id[19],department[10];int sex,age;float 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();system("pause");return 0;}

在释放建立对象时动态分配的内存这块不太上手
