天乾地支c語言代碼

1. 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;

}

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;

}
