万年历c语言编程
❶ 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;
}
(1)万年历c语言编程扩展阅读
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;
}

❻ 用C语言怎么编写这个万年历
核心算法：星期（0～6）=(年份系数+月份系数+日期)%7;
其中，年份系数我以2007年做参照，已知2007年，年份系数是0，往前往后分别是递减和递增。增减规律：非闰年为±1，闰年1～2月-2或+1，闰年3～12月+2或者-1。
其中，12个月份系数对应：0,3,3,6,1,4,6,2,5,0,3,5。
根据以上规律，只要利用循环，就可以的到对应系数和星期。
日历实现翻页功能，按键盘左右方向键可以翻译查看当年其他月份，按向上方向键可以返回菜单。
下面是代码：
#include <stdio.h>
#include <malloc.h>
#include <string.h>
#include <conio.h>
#include <math.h>
#include <time.h>
#define XY 2007
#define X07 0//以2007年年系数0做参照
int isLeapYear(int year);//判断是否是闰年，是返回1，否返回0
int addyx(int yx,int n);//年系数自增，0~6,n：自增的跨度，返回自增后的年系数
int getYX(int year,int month);//获得年系数0~6
int getMX(int month);//获得月系数
int getWeek(int yx,int mx,int day);//通过年月系数(yx:年系数；mx:月系数)及日期获取星期
char *getStrWeek(int yx,int mx,int day);//通过年月系数(yx:年系数；mx:月系数)及日期获取星期对应的中文字符串
int getMaxDay(int year,int month);//通过年月获取当月最大天数
void prCalendar(int year,int month);//打印日历
int showMeun();//打印主菜单
int getDuration(int year,int month,int day);//通过日期获取距今天数

❼ 用c语言编写万年历，要求输出任意一年的某月，能显示出这个月的日历
1、首先要判断一个年份是闰年还是平年，用一个子程序来做。
