c語言編寫萬年曆的源**如下：
#include
int week(int y,int m,int d);
int main()
char wk[7][3] = ,,,,,,};
int year, month, day, w;
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]=;
int c,w;
y %= 400;
<3)c = 5;
else
c = 6;
w = (y+y/4-y/100+r[m]+d+c)%7;
return w;
}擴充套件資料電子時鐘c語言版的源**如下：
#include
#include
#include
int main()
char str[50];
time_t t;
struct tm *nt;
while(1)
system("cls");//清屏函式
t=time(null);
nt=localtime(&t);
strftime(str,50,"%y-%m-%d %h:%m:%s 「，nt);
printf("現在時刻：%s\n",str);
getch();
return 0;
