http://acm.fzu.  这个是题目 。下面是我的代码   运行结果是对的  可是提交时总是wrong answer 麻烦指点下  谢谢啦
#include<stdio.h>
int main()
{
    int y,m,n,d,t,s,i,j,p;
    int a[12]={31,28,31,30,31,30,31,31,30,31,30,31};
    while(scanf("%d",&n)!=EOF)
    {
        for(i=0;i<n;i++)
        {
            t=0;s=0;
            scanf("%d%d%d",&y,&m,&d);
            if(y<1958||y>3000)break;
            if(m<10||(m==10&&d<=25))
            {
               t=y-1958;
               if((y%4==0&&y%100!=0)||(y%400==0))
                   a[1]=29;
               for(j=m-1;j<10;j++)
               {s=s+a[j];}
               s=s-6-d;
            }
            else if(m>10||(m==10&&d>25))
            {
                t=y-1957;
                if(((y+1)%4==0&&(y+1)%100!=0)||((y+1)%400==0))
                   p=299;else p=298;
                for(j=m-1;j<12;j++)
                {s=s+a[j];}
                s=s+p-d;
            }
            printf("%d days left for celebrating the %dth anniversary of the founding of Fuzhou University!\n",s,t);
        }
    }
    return 0;
}

也许你忽略了第三种情况。
if（）
else if（）
else
当输入错误数据时，不符合程序的‘确定性’，也就是说每一步都要有确定的意义

#include<stdio.h>
int main()
{
    int y,m,n,d,t,s,i,j,p;
    int a[12]={31,28,31,30,31,30,31,31,30,31,30,31};
    while(scanf("%d",&n)!=EOF)
    {
        for(i=0;i<n;i++)
        {
            t=0;s=0;
            scanf("%d%d%d",&y,&m,&d);
           
            if(m<10||(m==10&&d<=25))
            {
               t=y-1958;
               if((y%4==0&&y%100!=0)||(y%400==0))
                   a[1]=29;
               for(j=m-1;j<10;j++)
               {s=s+a[j];}
               s=s-6-d;
               a[1]=28;    //这里~
            }
            else if(m>10||(m==10&&d>25))
            {

                if(((y+1)%4==0&&(y+1)%100!=0)||((y+1)%400==0))
                   p=299;else p=298;
                for(j=m-1;j<12;j++)

看我注释的地方~

我看不懂题目,全英文的,无语.....

太感谢您了  我纠结了好久没发现这个小问题。
