定義一個日期類Date，main()函式完成對其的測驗。
Date類結構說明：
Date類的資料成員包括：
①私有資料成員：年year(int型)，月month(int型)，日day(int型)。
Date類成員函式包括：
①定義有參建構式Date(int ,int ,int )和拷貝建構式Date(Date &)，其中有參建構式引數默認值為1，輸出資訊“Constructor run”，拷貝建構式輸出資訊“CopyConstructor run”
②定義解構式，解構式輸出資訊“Destructor run”
③公有函式成員：void setYear(int )和int getYear()分別回傳和設定year
④公有函式成員：void setMonth(int )和int getMonth()分別回傳和設定month
⑤公有函式成員：void setDay(int )和int getday()分別回傳和設定day
⑥公有函式成員：void tomorrow( )和void yesterday( )實作日期加/減一天操作
⑦公有函式成員：void printMonthCalendar( )列印當月日歷，格式如下（每列寬度為3位，右對齊）（以2016年3月為例）
SunMonTueWedThuFriSat
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30 31
⑧公有函式成員：void chineseFormat( )和void americaformat( )分別顯示中式日期(例：2014年4月21日)和美式日期(例：Api 21, 2014)，其中美式格式中1~12月分別用Jan、Feb、Mar、Api、May、Jun、Jul、Aug、Sep、Oct、Nov、Dec表示
⑨私有函式成員：int isLeapYear( )確定當前年份是否為閏年，閏年回傳1，否則回傳0；
⑩公有函式成員：int weekDay( )回傳該天是星期幾，0~6分別表示Sun、Mon、Tue、Wed、Thu、Fri、Sat
注：在以上成員函式執行程序中，若輸入的日期引數值超界，則按照最接近輸入引數的有效日期值對待，例如：
假定輸入的month>12，則按照12對待，若輸入的month<1，則按照1對待；
假定當前month為12月，則若輸入的day>31，則按照31對待，若輸入的day<1，則按照1對待；
提示：cout.width(int)設定輸出項的寬度
裁判測驗程式樣例：
#include<iostream>
using namespace std;
int const monthDay[12]={31,28,31,30,31,30,31,31,30,31,30,31};
char* const weekName[7]={"Sun","Mon","Tue","Wed","Thu","Fri","Sat"};
char* const monthName[12]={"Jan","Feb","Mar","Api","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};
/*請在這里填寫答案*/
int main(){
int year,month,day;
Date d1;
Date d2(d1);
cin>>year>>month>>day;
d1.setYear(year);
d1.setMonth(month);
d1.setDay(day);
d1.yesterday();
d1.chineseFormat();
cin>>year>>month>>day;
d2.setYear(year);
d2.setMonth(month);
d2.setDay(day);
d2.tomorrow();
d2.americaformat();
d2.printMonthCalendar();
return 0;
}
輸入樣例：
2019 3 27
2016 2 31
輸出樣例：
Constructor run
CopyConstructor run
2019年3月26日
Mar 1,2016
SunMonTueWedThuFriSat
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30 31
