㈡ 用c語言編程萬年歷

/*以下程序在TC2 中通過*/
#include <stdio.h>
#include <conio.h>
#include <dos.h>

void rili(int,int);
int runniansub(int);
int week(int,int,int);
int monthday[12]={31,28,31,30,31,30,31,31,30,31,30,31};

int main()
{
struct date d;
getdate(&d);
printf("今天是：%d年 %d月 %d日\n",d.da_year,d.da_mon,d.da_day);
rili(d.da_year,d.da_mon-1);
system("pause");
return 0;
}

void rili(int year,int month)
{
int d,w,i,s,c,p;
char x;
while(month>11) {
month-=12;
year++;
}
while(month<0) {
year--;
month+=12;
}
if(runniansub(year)) monthday[1]=29;
printf("%d年%d月\n",year,month+1);
printf("S M T W T F S\n");
s=week(year,month+1,1);
for(i=0; i<3*s; i++ ) printf(" ");
c=s;
for(d=1;d<=monthday[month];d++) {
if(c>6) {
printf("\n");
c=0;
}
c++;
printf("%d",d);
printf("%s",(d<10)?" ":" ");
}
printf("\n");
printf("下月N，上月P，退出Q");

笨比 這都不會還學什麼啊 小垃圾

㈤ C語言程序設計萬年歷怎麼編寫

#include <stdio.h>

int IsLeapYear(int);

main()
{
int i;
int day;
int year;
int temp;
int temp_i;
long int Year_days = 0;
int Year_Start = 1;
int Per_Year_Days;
int month_day[]={31,28,31,30,31,30,31,31,30,31,30,31,29};

printf("Please enter the year: ");
scanf("%d",&year);

while(Year_Start < year)
{
if( IsLeapYear( Year_Start ) )
Per_Year_Days = 366;
else
Per_Year_Days = 365;

Year_days = Year_days + Per_Year_Days;
Year_Start++;
}

for( temp = 1; temp <=12; temp++ )
{
switch( temp )
{
case 1:
printf(" January(%d)\n",year);
break;
case 2:
printf(" February(%d)\n",year);
break;

break;
case 12:
printf(" December(%d)\n",year);
break;
}
i = Year_days % 7;
printf("Mon Tue Wed Thu Fri Sat Sun\n");
if( i != 0 )
for( temp_i = 0; temp_i < i; temp_i++)
printf(" ");
day = 1;
if( IsLeapYear(year) && temp == 2)
while( day <= month_day[12] )
{
if( day >1 )
if( Year_days % 7 == 0 )
printf("\n");
if( day >= 10 )
printf("%d ",day);
else
printf("%d ",day);
Year_days++;
day++;
}

else
while (day <= month_day[temp-1])
{
if( day > 1 )
if( Year_days % 7 == 0 )
printf("\n");
if( day >=10 )
printf("%d ",day);
else
printf("%d ",day);
Year_days++;
day++;
}
printf("\n");
if( getch() == 'q' )
exit(0);
}
getch();
}

int IsLeapYear( int year )
{
if ((year %4 == 0) && (year % 100 != 0) ||
(year % 400 == 0) )
return 1;
else
return 0;
}

㈥ c語言萬年歷編程解釋

首先從主函數入手
main()
{
int year,month; //初始化參數

printf("輸入年和月份:"); //在屏幕上輸入提示
scanf("%d%d",&year,&month); //輸入年和月
show(year,month); //顯示函數
}

然後進入show（）函數中進行一系列的運算。

其實這個都挺簡單的了，如果需要詳細解答，加我。

㈦ 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;

}

(7)c語言萬年歷編程擴展閱讀

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;

}

㈩ 萬年歷C語言編程全過程

#include<stdio.h>
#include<windows.h>
void main()
{
char ans;
do{
int year,month;//月份和年份
int days = 0;//月份總天數
int sum = 0;//天數總和
int first;//月份第一天
int month_sum[12] = {31,28,31,30,31,30,31,31,30,31,30,31};
printf("請輸入年份：");
scanf("%d",&year);
printf("請輸入月份：");
scanf("%d",&month);
do
{
if(month < 1 || month > 12)
{
printf("輸入錯誤。請重新輸入：");
scanf("%d",&month);
}
else
{
break;
}
}while(1);
//判斷離1990-1-1多少天。
for(int i = 1900; i < year; i++)
{
if(i % 4 == 0 && i % 100 != 0 || i % 400 == 0)
{
sum += 366;
}
else
{
sum += 365;
}
}
//判斷當年是不是閏年
if(year % 4 == 0 && year % 100 != 0 || year % 400 == 0)
{
month_sum[1] = 29;
}
//將月份總天數和年份總天數加起來
for(i = 1; i < month; i++)
{
sum += month_sum[i-1 ];
}
sum += 1;
//算出月份的第一天
first = sum % 7;
//輸入格式
printf("%d年%d月\n",year,month);
printf("\n------------------------------------------------------\n");
printf("日 一 二 三 四 五 六\n");
switch(first)
{
case 0:
break;
case 1:
printf(" ");
break;
case 2:
printf(" ");
break;
case 3:
printf(" ");
break;
case 4:
printf(" ");
break;
case 5:
printf(" ");
break;
case 6:
printf(" ");
break;
}
for(i = 1; i <= month_sum[month-1]; i++)
{
printf("%d",i);
if((first+i) % 7 == 0)
{
printf("\n");
}
else
{
printf("\t");
}
}
printf("\n");
printf("繼續？（y）：");
fflush(stdin);
ans = getchar();
system("cls");
if(ans != 'Y' && ans != 'y')
{
break;
}
}while(1);
}

剛剛做好的，望採納,可以實現循環輸入。
另：每月的第一天是距1900年的總天數除以7的余數來決定的，
