大神们帮忙看一下，为什么在慕课网的编译平台能编译出221天，换DEV-c++就编译成8天？
#include <stdio.h>
int main()
{
int year = 2008;
int month = 8;
int day = 8;
int sum=0;
int i;
for(i<1;i<month;i++)
{
switch(i)
{
case 1:
sum +=31;
break;
case 2:
if(year%400==0 || (year%4==0&&year%100!=0))
{
sum +=29;
}
else
{
sum+=28;
}
break;
case 3:
sum+=31;
break;
case 4:
sum+=30;
break;
case 5:
sum+=31;
break;
case 6:
sum+=30;
break;
case 7:
sum+=31;
break;
case 8:
sum+=31;
break;
case 9:
sum+=30;
break;
case 10:
sum+=31;
break;
case 11:
sum+=30;
break;
case 12:
sum+=31;
break;
}
}
sum+=day;
printf("%d年%d月%d日是该年的第%d天",year,month,day,sum);
return 0;
}
