C++作业1：单个类的设计（验证型）

题目描述

合理设计一个类，该类需要对数据成员进行合法性验证、初始化、修改、获取、输出等基本操作外，还应能完成其他一些合理的功能操作（可以自行思考设计）。并在程序合适的位置中生成该类的对象，并让所设计的功能发挥作用。可以参考以下提示，选择一个参考项或自己进行拟定一个抽象的事物进行单个类的设计。

目的

1） 巩固类的定义，成员变量、成员方法的定义；

2） 巩固类的对象的定义，对象对成员变量、成员方法的访问；

要求

在main函数定义并使用对象、指针及引用三种方法完成完成员工的信息显示，并使用拷贝构造函数。

参考设计

参考1：员工类

数据成员：姓名，年龄，性别，身份证，工号，入职时间。

成员函数：显示员工信息，修改入职时间。

程序流程图

参考代码

// CStaff 员工类

#pragma once
#include <string>
using namespace std;
class CStaff
{
private:
	string m_nName;//姓名
	string m_nAge;//年龄
	string m_nGender;//性别
	string m_nID;//身份证
	string m_nNumber;//工号
	string m_nEnTime;//入职时间
	string m_nPosition;//职位
public:
	CStaff();
	CStaff(string Name, string Age, string Gender, string ID, string Number, string EnTime, string Position);
	void SetAllinformation(string Name, string Age, string Gender, string ID, string Number, string EnTime, string Position);
	void SetName(string nName);
	void SetAge(string Age);
	void SetGender(string Gender);
	void SetID(string ID);
	void SetNumber(string Number);
	void SetTime(string EnTime);
	void SetPosition(string Position);
	string ShowInformation();
	~CStaff();
