怎么样令A为显示每个学生五门功课的最低和最高分，B为显示没门功课都不及格的人数，C为：检索学号为某指定数的学生信息

可以试试调用函数！！！

怎么操作？

void fnPlan_A(struct person data[],int n)
{
    for(k=1;k<=N-1;k++)
    {
        for(i=N-1;i>=k;i--)
        {
            if(data.score[i]<data.score[i-1])
            {
                t=data.score[i];
                data.score[i]=data.score[i-1];
                data.score[i-1]=t;
            }
        }
    }
    printf("%d%d",score[0],score[N-1]);
}
这里面不是data.score[i]么？应该写什么？
