请教各位，我这样的代码有问题吗？答案是正确的
#include <stdio.h>
int main()
{
/* 定义需要计算的日期 */
int year = 2008;
int month = 8;
int day = 8;
int i,l;
switch(month)
{
case 1:i=0;break;
case 2:i=31;break;
case 3:i=59;break;
case 4:i=90;break;
case 5:i=120;break;
case 6:i=151;break;
case 7:i=181;break;
case 8:i=212;break;
case 9:i=243;break;
case 10:i=273;break;
case 11:i=304;break;
case 12:i=334;break;
}
i += day;
if((year%4 ==0 && year%100 !=0) || year%400 ==0)
i++;
printf("%d年%d月%d日是该年的第%d天", year,month,day,i);
return 0;
}
