下面是我编写的程序：
#include<stdio.h>
main()
{
int year,month;
printf("请输入年月\n");
scanf("%d%d",&year&month);
if((year%400==0)||(year%4==0&&year%100!=0))
{
switch(month)
case 2:
days=29;
break;
case 4:
case 6:
case 9:
case 11:
days=30;
break;
default:
days=31;
break;
printf("%d天\n",days);
}
else
{
switch(month)
case 2:
days=28;
break;
case 4:
case 6:
case 9:
case 11:
days=30;
break;
default:
days=31;
break;
printf("%d天\n",days);
}
}
总是提示有一个错误。找不到错在哪
