这是题目内容



以下是本人代码

#include<stdio.h>

int main()
{
    int year,month,day,k,sum,i;
    int a[2][13]=
    {
        {0,31,28,31,30,31,30,31,31,30,31,30,31},
        {0,31,29,31,30,31,30,31,31,30,31,30,31},
    };

    while(scanf("%d%d%d",&year,&month,&day)!=EOF)
    {
        if((year%4==0&&year%100!=0)||(year%400==0))
            k=1;
        else
            k=0;

        if(month>12)
            printf("Illegal date\n");
        else if(day>a[k][month])
            printf("Illegal date\n");
        else
        {
            sum=0;
            i=1;
            while(i!=month)
            {
                sum=sum+a[k][i];
                i++;
            }
            sum=sum+day;
            printf("%d\n",sum);
        }

    }

    return 0;
}

小于或等于0未判断。

最起码你连『Hint 一个提示：年月日均不可小于等于0』都没理睬。

恩恩，我题目理解错误，谢谢
