用c++编写日历程序
C语言编写万年历
C语言编写万年历程序实现万年历的查询功能，根据使用者输入的年份与月份输出本月的日历。
可以查询1950年之后的日期，查询范围可以在junde函数中进行修改。

C语言万年历代码
题目：年历显示。
功能要求：（1）输入一个年份，输出是在屏幕上显示该年的日历。
假定输入的年份在1940-2040年之间。
（2）输入年月，输出该月的日历。
（3）输入年月日，输出距今天还有多少天，星期几，是否是公历节日。

自己做的日历(C语言)
本帖最后由 kekeyu 于 2010-8-15 16:59 编辑
c语言实现一个简单日历
c语⾔实现⼀个简单⽇历满⾜三个需求:1．输⼊⼀个年份，输出是在屏幕上显⽰该年的⽇历。
假定输⼊的年份在1940-2040年之间。
2．输⼊年⽉，输出该⽉的⽇历。
3．输⼊年⽉⽇，输出距今天还有多少天，星期⼏，是否是公历节⽇。

C语言电子日历程序设计
C语言电子日历程序设计一、项目要求设计一款电子日历，通过选择，实现如下5项功能：选择操作：1选择操作：2选择操作：3，根据输入的年-月，显示月历。
选择操作：4，根据输入年，显示年历。
部分年历如下图所示。
选择操作：5二、编译环境 Visuall C++6.0 + EasyX(Visual C++ 6.0)，采用C++程序。
1. 创建工程在Visual C++6.0中，选择“文件”—>“新建”,弹出如下界面。
先创建工程，选择“Win32 Console Application”工程，给出存储位置和工程名，点“确定”按钮。
后面选择默认，即可。
2. 在工程中创建C++文件在Visual C++6.0中，选择“文件”—>“新建”,弹出如下界面。
刚才创建工程名给出文件名，不要给扩展名，默认创建C++文件，扩展名为cpp 点“确定”按钮，完成C++文件创建。
界面效果如下图所示。
3. 添加类库因为C语言中的图形库头文件graphics.h是Dos环境下的，只能使用TurboC进行编译调试，TurboC2.0环境不是图形化可视界面，调试程序不如VC++6.0。
但在Visual C++6.0中，原有C语言中的图形库头文件graphics.h不可用，有些人员开发了DLL文件，让Visual C++6.0能识别C语言的graphics.h，方便利用C语言进行图形化的设计。
即，要进行图形化设计，需要安装EasyX，添加类库。
安装过程如下：（1）双击EasyX中的Setup文件，效果如下图所示。
单击“下一步”，选择你的开发平台，安装类库。
这里选择Visual C++6.0即可，点击“安装”,弹出安装成功，“关闭”即可。
三、相关知识1. 本项目涉及到的头文件#include <stdio.h>#include <stdlib.h>#include <graphics.h>#include <conio.h>#include <math.h>（1） graphics.h是TC里面的图形库，分为：像素函数、直线和线型函数、多边形函数、填充函数等。
