一、欧拉欧拉欧拉欧拉欧拉
用伪C++的面向对象的方法做了个日历（设计得完全不像类 ），功能主要如下：
- 跳转到某年某月某天
- 查看某年的全部日历
- 推算几天前是什么日子
- 推算几天后是什么日子
- 推算两个日期之间的间隔
- 查询星座
程序内的每一处都做了输出检测（包括日期输出与选择时输入的数字）
二、效果图
（可能有潜在bug，虽然改了很多次了…(T ^ T) )
话不多说，直接上效果图：
2.1 主界面
2.2 功能1 —— 日期跳转
如果输入的年月日为负数或者日期超过月份的最大天数时会报错，就像这样：
2.3 功能 2 —— 日历查看
打印方式为双列打印
2.4 功能3 —— 日期向前推算
打开手机日历验证以下：
2.5 功能4 —— 日期向后推算
同样，手机验证：
2.6 功能5 —— 计算日期间隔
2.7 功能6 —— 查询星座
三、不说了，直接看代码吧
为什么说是伪C++的面向对象呢 ？（至少自己感觉不像），来看看Calender类吧：
//Calender.h
#include <iostream>
#include <tchar.h>
#include <time.h>
#include <Windows.h>
#include <iomanip>
#include <string>
using namespace std;
extern int arrDays[12][6][7];
class Calender
{
public:
Calender();//默认获取系统时间
Calender(int year, int month, int day);//自行定义
~Calender();
static bool isLegalDate(int y, int m, int d); //判断输入的日期是否合法
static void changeFebDay(int y);//根据年份改变2月份天数
static bool isLeapYear(int y);//判断是否为闰年
static int isWeek(int y,int m,int d);//判断某年某月某日设计星期几
static int totalDay(int y, int m, int d);//计算某天是第几天
static string returnWeek(int w);//返回星期几的中文
static int returnDay(int y,int m);//返回某年某月的天数
static int returnYear(int y);//返回对应年份的总天数
static string returnSX(int y);//返回生肖
static void initCalender(int y);//初始化日历
static void print(int arrDay[]);
static void printMonth(int y,int m,int d);//打印某年某月的日历
static void printCalender(int y);//双行打印年份对应的日历
static void dateForwardReckon(int y, int m, int d, int numOfDay);//日期向前推算
static void dateBackReckon(int y, int m, int d,int numOfDay);//日期向后推算
static int dateInterval(int y1, int m1, int d1, int y2, int m2, int d2);//推算日期间隔天数
static void isConstell(int y,int m, int d);//查询星座
void showDate();//显示时间
int dateInterval(int y1, int m1, int d1);
void setYear(int y);
void setMonth(int m);
void setDay(int d);
int getYear();
int getMonth();
int getDay();
private:
static string months[12];
static int days[13];
static string weeks[7];
static string sx[12];
int year;
int month;
int day;
};
很多都是静态函数，而且函数超级多有木有（设计得不太合理），运算符重载、继承、多态什么的都没有（这些都没学，甚至类也还没学…)（不要在意这些细节(〃‘▽’〃)）
