求帮助找bug）问题：判断给定日期是在本年的第几天

#include<stdio.h>
int main()
{
int year,month,day,total,feb;
printf("请输入一个日期(YYYY-MM-DD)");
scanf("%d-%d-%d",&year,&month,&day);
if((year%100==0&&year%400==0)||(year%4==0&&year%100!=0))
feb=29;
else
feb=28;
switch(month)
{
case 1:total=day;break;
case 2:total=31+day;break;
case 3:total=31+feb+day;break;
case 4:total=62+feb+day;break;
case 5:total=92+feb+day;break;
case 6:total=123+feb+day;break;
case 7:total=153+feb+day;break;
case 8:total=184+feb+day;break;
case 9:total=215+feb+day;break;
case 10:total=245+feb+day;break;
case 11:total=276+feb+day;break;
case 12:total=306+feb+day;break;
}
printf("%d",&total);
system("pause");
return 0;
}

printf("%d",total);
