求大佬解释。
#include<stdio.h>
int main()
{
int year=2008;
int month=8;
int day=8;
int sum,j;
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;
case 9:sum=243;break;
case 10:sum=273;break;
case 11:sum=304;break;
case 12:sum=334;break;
}
sum=sum+day;
if(year%4==0&&year%100!=0)
j=1 ;
else j=0;
if(j==1&&month>2)
sum++;
printf("%d年%d月%d日是该年中得第%d天",year,month,day,sum);
return 0;
}
显示运行成功输出错误
