小程序如何修改？？
//编写一个程序，当用户输入年份与月份时，电脑会自动输出当月的天数
#include<stdio.h>
Program(int year,int month);
void main()
{
int year,month;
printf("Please input the value of year and month: ");
scanf("%d,%d",&year,&month);
Program(year,month);
}
Program(int year,int month)
{
int days;
switch(month)
{
case 1,3,5,7,8,10,12: days=31;break;
case 4,6,9,11: days=30;break;
case 2: if((year%400==0)||(year%4==0&&year%100!=0)) days=29;
else days=28;break;
}
return days;
}

"case + (int/char) + :"这个是C标准规定的语法,写在一起的话，对于编译器来说是无法识别的语法，自然报错~Top
