请问哪里不对啊 运行结果总是0⃣️

#include
int main(void)
{
int day,month,year,sum,leap;
printf("please input year,month,day\n");
scanf("%d,%d,%d",&year,&month,&day);

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=15l;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%400==0||(year%4==0 && year%100!=0))
    leap=1;
else
    leap=0;
if (leap==1&&month>2)
    sum++;
printf("It is the %dth day. \n",sum);
return 0;

}

输入值跟你scanf的格式要一致，这里边有逗号 那就是输入 2022,1,6,如果 scanf("%d%d%d") 之间没有逗号，那就2022 1 6可以通过空格隔开输入

scanf("%d %d %d",&y,&m,&d);
去掉%d之间的逗号
