部分代码：
int main(int argc, char *argv[])
{
int month,days,year,days_per_year,i=0;
char str[]="Please input year,month,days:\n";
int a[12]={31,28,31,30,31,30,31,31,30,31,30,31};
days_per_year=0;
while(str[i]!='\0')
{
putchar(str[i]);
Sleep(150);
i++;
}
scanf("%d,%d,%d",&year,&month,&days);
if((year%4==0&&year%100!=0)||(year%400==0))
{
a[1]=29;
}
for(i=0;i<month-1;i++)
{
days_per_year+=a[i];
}
days_per_year+=days;
printf("The days_per_year is:%d\n",days_per_year);
return 0;
}
