armani女香:有会C的吗？帮我看看这到题！？~

#include <stdio.h>
void main()
{
int day,month,year,sum,leap;
printf("\nplease input year,month,day\n");
scanf("%d,%d,%d",&year,&month,&day);
switch(month)/*先计算某月以前月份的总天数*/
{
case 1:sum=0;break;
case 2:sum=31;break;
case 3:sum=59;break;
case 4:sum=90;break;
case 5:sum=120;break;
case 6:sum=151;break;
case 7:sum=181;break;
case 8:sum=212;break;
case 9:sum=243;break;
case 10:sum=273;break;
case 11:sum=304;break;
case 12:sum=334;break;
default:printf("data error");break;
}
sum=sum+day; /*再加上某天的天数*/
if(year%400==0||(year%4==0&&year%100!=0))/*判断是不是闰年*/
leap=1;
else
leap=0;
if(leap==1&&month>2)/*如果是闰年且月份大于2,总天数应该加一天*/
sum++;
printf("It is the %dth day.",sum);}

这么简单问题也来问

你那是不是有点不好哦，
看看我的
简单多了
不过不要忘记加分哦
#include<stdio.h>
main()
{
int year;
printf("please a NO. year:");
scanf("%d",year);
if(((year%4==0)&&(year%100!=0))||(year%400==0))
printf(%d是闰年\n",year);
else
printf("%d不是闰年\n",year);
}
