❶ 請問寫一個日歷的c語言程序，代碼怎麼寫
#include<conio.h>
#include<stdio.h>
#include<time.h>
#include<stdlib.h>
constmonthDay[]={0,31,28,31,30,31,30,31,31,30,31,30,31};
intisLeap(intyear)
{
if(year%4)return0;
if(year%400)return1;
if(year%100)return0;
return1;
}
intgetWeek(intyear,intmonth,intday)
{
intc,y,week;
if(month==1||month==2)//判斷month是否為1或2
{
year--;
month+=12;
}
c=year/100;
y=year-c*100;
week=(c/4)-2*c+(y+y/4)+(13*(month+1)/5)+day-1;
while(week<0){week+=7;}
week%=7;
returnweek;
}
voiddisplay(intyear,intmonth)
{
intmonthDays,weekFirst,i;
monthDays=monthDay[month]+(month==2?isLeap(year):0);
weekFirst=getWeek(year,month,1);
system("cls");
printf("-------%4d年----%2d月------- ",year,month);
printf("星期日星期一星期二星期三星期四星期五星期六 ");
for(i=0;i<weekFirst;i++)printf("");
for(i=1;i<=monthDays;i++)
{
printf("%8d",i);
weekFirst++;
if(weekFirst>=7){printf(" ");weekFirst=0;}
}
}
voidmain()
{
intyear,month,chr;

structtm*tblock;
timer=time(NULL);

if(chr==0x4b)/*方向鍵(←)*/
{

if(month<1){month=12;year--;}
}
elseif(chr==0x4d)/*方向鍵(→)*/
{
month++;
if(month>12){month=1;year++;}
}
}
elseif(chr=='q'||chr=='Q')break;
}
}
❷ C語言編寫日歷
#include <stdio.h>
int month[13]={0,31,28,31,30,31,30,31,31,30,31,30,31};
void print_calendar(int y);
void main()
{
int y;
printf("Calendar system :\n");
printf("Please input a year between 1600 & 2500:");
while(scanf("%d",&y)!=EOF)//輸入年份
{
if (y<1600 || y>2500)
{
printf("Invalid input. Please try again!\n");
printf("Please input a year between 1600 & 2500:");
continue;
}
print_calendar(y);
}
}
void print_calendar(int y) //列印日歷
{
int i,sum,days,k,m;
char monthname[12][20] = {"January","February","March","April","May","June","July","August","September","October","November","December"};
if((0==y%4&&y%100!=0)||0==y%400 ) //閏年判斷
month[2]=29;
for(m=1;m<13;m++)
{
days = 0;
for (i=1;i<m;i++) //計算m月1號是第幾天
days+=month[i];
days++;
sum=y-1+(y-1)/4-(y-1)/100+(y-1)/400+days;
k=sum%7; //k是星期幾,k=0星期日
printf("%s %d\n",monthname[m-1],y);
printf(" S M Tu W Th F S\n");
printf("%*d",3*(k+1)-1,1);//先輸出3*(k+1)-1個空格，在輸出1
k++;
for(i=2;i<=month[m];i++)
{
if(k == 7)
{
printf("\n");
k=0;
}
if (k == 0)
printf("%2d",i);
else
printf("%3d",i);
k++;
}
printf("\n\n");
}
}
❸ 用C語言怎麼編寫萬年歷
C語言編寫萬年歷的源代碼如下：
#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;
}
(3)c語言編寫日歷擴展閱讀
電子時鍾C語言版的源代碼如下：
#include<stdio.h>
#include<time.h>
#include<string.h>
int main()
{
char str[50];
time_t t;
struct tm *nt;
while(1)
{
system("cls");//清屏函數
t=time(NULL);
nt=localtime(&t);
strftime(str,50,"%Y-%m-%d %H:%M:%S 「，nt);
printf("現在時刻：%s ",str);
}
getch();
return 0;
}
❹ C語言編寫年歷
只找到這個列印的,
你自己看看,
#include <stdio.h>
void main()
{
int i,j,k,year,week;
int day[]={31,28,31,30,31,30,31,31,30,31,30,31};
char month[12][10]={"January","February","March","April","May","June","July","August","September","October","November","December"};
printf("Input year you want to print:");
scanf("%d",&year);
if((year%4==0&&year%100!=0)||(year%400==0)) day[1]++; //判斷是否閏年
week=(35+year+year/4-year/100+year/400)%7; //計算當年的1月1日是周幾的公式
for(i=0;i<12;i++)
{
printf("\n%s\n",month[i]); //輸出月份的英文
printf("Sun Mon Tue Wed Thu Fri Sat\n"); //輸出表頭
for(k=0;k<week;k++) printf(" "); //每月一號對齊它的星期數
for(j=1;j<=day[i];j++)
{
printf("%3d ",j);
if(++week>=7)
{
printf("\n");
week=week%7;
}
}
printf("\n");
}
}
❺ 求C語言編日歷源代碼的詳細說明
/*
稍微改了下對齊格式，加了注釋
*/
/*
1、閏年的演算法:
如果某年能被4整除但不能被100整除,
或者能被400整除,
則該年是閏年.
用表達式表示就是
(year
%4
==
0
&&
year%100
!=
0)
||
(year%400
==
0)
2、計算某一天是星期幾:
已知1900年的1月1號為星期一,
然後就可以用某一天和1900年的1月1號相差的天數對7取余來求星期,
本題是用的公元1年的1月1號作為基準

❾ 如何用C語言編寫日歷程序
這個程序基本上給你寫出來了
由於操作比較機械化
所以一些重復的機械操作我（兩個switch中的省略了一些）
我是以2008年1月1日為基準的
那天是星期二
可以查找從那天開始以後的89年中的任意一天
有於 int型的取值范圍所限定的
你自己看看程序把 很簡單
#include<stdio.h>
void lab()
int xinqi()
//計算星期
xinqi(int y,int m,int d)
{
int a,b,star;
int a[12]={31,59,90,120,151,181,212,243,273,304,334,365};
switch(m)
{
case 1: a=m;
case 2: a=m+31;
case 3: a=m+59;
//後面以此類推
}
b=(y-2008)/4;
a=365*(y-2008)+b;
star=a%7+2;
switch(star)
{
case 1: printf("Mon");
case 2: printf("Tue");
//下面以此類推
}
}
//計算天數並輸出相應日期
lab(int y,int m,int d)
{
int a[12]={31,59,90,120,151,181,212,243,273,304,334,365};
int x,run,flag;
if((x-y)%4==0) run=1;
else run=0;
switch(m)
{
case 1:{ flag=a[m]; printf("Jan,%dth,%d",d,y); xinqi(y,m,d);}
case 2:{ flag=a[m]; printf("Feb,%dth,%d",d,y); xinqi(y,m,d);}
case 3:{ flag=a[m]+run; printf("Mar,%dth,%d",d,y); xinqi(y,m,d);}
//後面依次類推
}
}
}
void main()
{
int y,m,d;
printf("輸入:");
scanf("%d %d %d ",&y,&m,&d);
lab(y,m,d);
}
❿ 用C語言編寫程序列印任意年份的日歷
#include <stdio.h>
