上面搞错了
#include<stdio.h>
int main()
{
    int year,month,day;
    scanf("%d%d",&year,&month);
    switch(month)
    {
    case 4:
    case 6:
    case 9:
    case 11:
        day=30;break;
    case 1:
    case 3:
    case 5:
    case 7:
    case 8:
    case 10:
    case 12:
        day=31;break;
    case 2:
        if(year%400==0 || year%100!=0 && year%4==0) day=29;
        else day = 28;
        break;
    }
    printf("%d-%d-%d\n",year,month,day);
    return 0;
}
