/* * 作 者: 霍雨佳 * 完成日期:2014 年5月13日 * 版 本 号:v1.0 * 问题描述:定义一个名为CPerson的类,有以下私有成员:姓名、身份证号、性别和年龄,成员函数:构造函数、析构函数、输出信息的函数。 * 并在此基础上派生出CEmployee类,派生类CEmployee增加了两个新的数据成员,分别用于表示部门和薪水。 * 样例输入: * 样例输出: * 项目要求:要求派生类CEmployee的构造函数显示调用基类CPerson的构造函数,并为派生类CEmployee定义析构函数,定义输出信息的函数。 * 项目拓展要求:字符串除了用C++扩充的string类型外,按C语言的传统,还用char *表示。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。) */ #include <iostream> #include <string.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(); }; 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<<"name:"<<m_szName<<endl; cout<<"id: "<<m_szId<<endl; cout<<"sex(0:women,1:man):"<<m_nSex<<endl; cout<<"age: "<<m_nAge<<endl; } CPerson::~CPerson() { delete[]m_szName; delete[]m_szId; } 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(); }; 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() { Show1(); cout<<"department:"<<m_szDepartment<<endl; cout<<"salary: "<<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(); return 0; }
