设计一个类CDateinfo，编写主函数测试编写类的正确性。要求其满足下述要求：
 要求有一个无参数的构造函数
 其默认年、月、日分别为：2007，5，23
 要求有一个带参数的构造函数，其参数分别为：年、月、日
 要求用一个成员函数实现日期的设置
 要求用一个成员函数实现日期的获取。

#include <iostream>
using namespace std;
class CDateinfo
{
public:
CDateinfo();
CDateinfo(int year,int month,int day);
void input();
void output();
private:
int year;
int month;
int day;
};
CDateinfo::CDateinfo():year(2007),month(5),day(23)
void CDateinfo::input()
{
cout<<"enter the year:";
cin>>year;
cout<<"enter the month:";
cin>>month;
cout<<"enter the day:";

}
void CDateinfo::output()
