【任務2】定義一個名為CPerson的類,有以下私有成員:姓名、身份證號、性別和年齡,成員函式:建構函式、解構函式、輸出資訊的函式。並在此基礎上派生出CEmployee類,派生類CEmployee增加了兩個新的資料成員,分別用於表示部門和薪水。要求派生類CEmployee的建構函式顯示呼叫基類CPerson的建構函式,併為派生類CEmployee定義解構函式,定義輸出資訊的函式。 #include <iostream> #include <string.h> #include <iomanip>//setw:設定輸出資料的寬度,使用時應#include <iomanip.h> 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(); //需要釋放建立物件時動態分配的記憶體 }; 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(); }; 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; }
