int leap=NO;
if(year%4==0 && year%100!=0 || year%400==0)

return leap;
}
int week_of_firstday(int year)
{
int n;
n=(year+(year-1)/4-(year-1)/100+(year-1)/400)%7;

return n;
}
int main()
{

printf("---------------------\n");
printf("日 一 二 三 四 五 六\n");
printf("---------------------\n");
for(i=0;i<weekday;i=i+1)
printf(" ");
if(month==4||month==6||month==9||month==11)
len_of_month=30;
else if(month==2)
{
if(isleap(year))
len_of_month=29;
else
len_of_month=28;
}
else
len_of_month=31;

for(day=1;day<=len_of_month;day++)
{
if(day>9)
printf("%d ",day);
else
