这个万年历比较好看哈！你可以试试这个？
❼ 用C语言怎么编写万年历
C语言编写万年历的源代码如下：
#include <stdio.h>
int week(int y,int m,int d);
int main()
{
char wk[7][3] = {{"天"},{"一"},{"二"},{"三"},{"四"},{"五"},{"六"}};
int year, month, day, w;
scanf("%d %d %d", &year, &month, &day);
w = week(year, month, day);
printf("%d年%d月%d日 星期%s", year, month, day, wk[w]);
}
int week(int y,int m,int d)
{
static int r[13]={0,0,3,3,6,1,4,6,2,5,0,3,5};
int c,w;
y %= 400;
if ((y==0||y%4==0&&y%100!=0)&&m<3)
c = 5;
else
c = 6;
w = (y+y/4-y/100+r[m]+d+c)%7;
return w;
}
(7)c语言课程设计制作万年历扩展阅读
电子时钟C语言版的源代码如下：
#include<stdio.h>
#include<time.h>
#include<string.h>
int main()
{
char str[50];
time_t t;
struct tm *nt;
while(1)
{
system("cls");//清屏函数
t=time(NULL);
nt=localtime(&t);
strftime(str,50,"%Y-%m-%d %H:%M:%S “，nt);
printf("现在时刻：%s ",str);
}
getch();
return 0;
}
❽ C语言课程设计-万年历
1.系统封面设计
内容：题目名称（中英文）、进入(中英文)、作者：***、时间：****-**-**
2.输入界面
内容：（1）密码口令输入及容错（3次）
（2）年份的输入及容错（3次）
3.日历计算设计
（1）求某月某日实行奇迹的函数（邱每月一号的星期数）。算法：（y-1）+(y-1)/4-（y-1）/100+(y-1)/400+c 得出S (y为年份，c为某月某日是这一年的第几天，S为总的天数)
（2）邱某月某日至这一年第几天的函数（求c） 闰年的算法: y/400==0 ?或y/400==0&&y/100!=0
根据（1）（2）求出每个月的日期
4、日历格式显示设计
要求：每屏显示4个月。
-------------------------------
❾ 用c语言编写万年历
写万年历程序，您需要先了解万年历的特点
下面是万年历的特点（复制粘贴的）：
1. 平年365天（52周+1天），闰年366天（52周+2天）。平年2月28天，闰年2月29天。
由于公元1月1日设为星期六，故3月1日为星期三。 ——注意这个“三”
为使算法达到最简，故本算法以“星期”为计算单位。且选3月1日为基月。
2. 每400年整一闰，或每4年且不为百年的一闰。(原因：地球绕太阳一周的时间是365天5小时46秒，为了使一年的天数为整数，将一年的天数定为365天，余下的时间积累起来，四年就是23小时15分4秒，将近一天，把这一天加在某年的二月而成29天，该年称为闰年，其它年称为平年。但四年加一天又多用了44分56秒，这个数积满400年为三天。因此400年中只能有97个闰年，所以凡能被400整除，或不能被100整除但能被4整除的年份为闰年。)
所以百年%4=0闰或（年%4=0并且年<>0）闰。
3. 每 4年（3个平年+1个闰年）共208周+5天 ——注意这个“5天”
每百年共100*（208周+5天）-1天=5217周+5天 ——注意这个“5天”(整百年暂设为平年)
每400年共4*（5217周+5天）+1天（整400年闰）=20871周+0天——注意这个“0天”和“1天”(4个整百年只有一个闰年)
即400年一轮回！（原来万年历400年前是一家）
至于你说的日期和星期对齐，给你一点思路参考：每一行是7天，可以设定每一天占10个字符（同时上面的星期也得占满10个字符），假设本月第一天是星期4，那么在输出1之前需要先输出10×3个字符来占位，当输出星期天的日期之后换行，之后的就简单了

万年历算星期几
只要随便说出公元几几年几月几日就可以马上算出是星期几.
只要计算出日的代码,月份代码,年份代码.三个加起来除以七的余数就是星期几,（如余数是三,则就是星期三）.
日的代码计算：日的代码最简单,就是它本身,是几号就是几.
月份代码计算：月份代码也很简单,下面有十二个数：1 4 4 7 2 5 7 3 6 1 4 6,分别代表一至十二月份每个月的代码.比如,九月份的代码为6.（据来宾介绍,他是用逆推的方法,计算出这12个月份代码的,即知道某年某月某日是星期几,反过来推算月份代码.）
年份代码计算：年份代码相对比较复杂,先记住2000年对应的年份代码是4,这是基础代码,牢记即可.
假如大于2000年,比如2010年,则对应的年份代码是（2010－2000）÷4=2……2,再用基数代码4减去2倍的商加上余数再加1.即4－2×2+2+1=3,则2010年对应的年份代码为3.如果没有余数,即润年,则余数后面的1也不用加.比如2008年,对应的年份代码为0.
假如小于2000年,比如1991年,则对应的年份代码是（2000－1991）÷4=2……1,再用基数代码4加上2倍的商减去余数.即4+2×2－1=7,则1991年对应的年份代码为7.
再记住1个特殊情况,即润年的3到12月份到最后要加1.
1949年10月1日.
则（2000－1949）÷4=12……3,再4+2×12－3=25,年份代码计算结果为25,加上10月份的代码1,再加上日的代码1,等于27.再除以七的余数为6,则这一天为星期六.
