求大神看看
#include <stdio.h>
int main()
{
int year = 2008;
int month = 8;
int day = 8;
int sum;
switch(month)
{
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;
}
if(year%400==0||(year%4==0&&year%100!=0)||month>2)
sum++;
else
sum=sum+day;
printf("%d年%d月%d日是该年的%d天",year,month,day,sum);
return 0;
}
我这样为什么结果是213天呀
