struct student
{
    float score;
    struct student * next;
}
fun(struct student * h)
{
   float max=h->score;
   h=h->next;
   while(h!=NULL)
    {
       if(h->score>max) max=h->score;
    }
}
可以动态分配内存；是程序简洁
一般大程序都少不了链表

float fun(struct student * h)
{
   float max=h->score;
   h=h->next;
   while(h!=NULL)
    {
       if(h->score>max) max=h->score;
    }
      return max;
}

那主函数应该怎么编写赋值啊,我这样编结果有12个error:
void main()
{
    struct stud_type
    {char name[20];
    long num;
    int age;
    char sex;
    float score;
    }*h;
    h=&student[0].score[0];
    struct stud_type student[3]={{"Wang Li",200701,18,'M',90.5},
    {"Zhang Fun",200702,19,'M',89.5},{"Li Ning",200703,'F',98}};
printf("%f\n",fun(h));
}

printf("%f\n",fun(h));
}

又搞了一下主函数只有3个错了,但还是有错,各位高手帮忙啊:
#include<stdio.h>
struct student
{
float score;
struct student * next;
}
struct student *fun(struct student *h)
{
  struct student *p,*q;
  p=q=h;
while(p!=NULL)
{
  if(p->score<p->next->score)
   q=p->next;

p=p->next;

}
return q;
  
}
void main()
{
    struct student *h,a[3]={90.5,89.5,98};
h=&a[0];
printf("%f\n",fun(h));
}

你好 这个看看C语言书就OK了  特别是指针和链表这两章 好好看看

首先要谢谢你,但是你的程序好象还有些问题,它不论怎样总是只输出第3个数
好象起不到比较的作用...

呵呵，又开了一个玩笑，不是我故意的，5分钟解决
#include<stdio.h>
struct student
{
float score;
struct student * next;
};
struct student *fun(struct student *h)
{
  struct student *p,*q;
  p=q=h;
while(p ->next!=NULL)
{
  if(p->score < p->next->score)
   q=p->next;

p=p->next;

}
return q;
  
}
int main()
{
    struct student *h,a,b,c;
    a.score=80.5;
    h=(struct student *)malloc(sizeof(struct student));
h=&a;
b.score=55.5;
h->next=(struct student *)malloc(sizeof(struct student));
h->next=&b;
c.score=10.5;
h->next->next=(struct student *)malloc(sizeof(struct student));
h->next->next=&c;
h->next->next->next=NULL;
printf("%f\n",(fun(h))->score);
system("pause");
return 0;
}

恩,这次好了,谢谢.
其实有句话想对你说..你的头像象个明星..胡彦斌..
