大家帮我看看这个程序！输入时候一直输下去了，没有反应（创建链表的时候）！

#include <stdio.h>
#include <stdlib.h>


 struct student

 { 
     char name[8];
     float high;
     long int weight;
     struct student *next;

 };


 int n,i;

 struct student *creat()//创建链表
 { 
      i=1;
     struct student *p,*head,*stud;
     head=NULL;
     stud=p=(struct student *)malloc(sizeof(struct student));
     printf("请输入学生 %d 的身高体重姓名:",i);
     scanf("%s%f%ld",&stud->high,&stud->weight,&stud->name);
    
     while(stud->high!=0)
     {
         n++;
         if(n==1)
         {  
             head=stud;
             head->next=NULL;
         }
         else
             p->next=stud;
             p=stud;
          stud=(struct student *)malloc(sizeof(struct student));
          printf("请输入学生 %d 的姓名身高体重:",++i);
          scanf("%s%f%ld",&stud->high,&stud->weight,&stud->name);
         
     }
     p->next=NULL;
     return(head);

 }



 struct student * search(struct student *head)//找出高度最高的那个学生
 {  
     struct student *p,*q,*t;
     float k;
     t=p=head;
     do
     { 
         if(t->high<p->high)
         {
              k=t->high;
              t->high=p->high;
              p->high=k;
              q=p;
         }
         p=p->next;
     }while(p!=NULL);
         return q;


 }


 struct student * find(struct student *head)//找出体重最重的那个学生
 { 
     struct student *p,*q,*t;
     int m;
     t=p=head;
     do
     {
         if(t->weight<p->weight)
         {
             m=t->weight;
             t->weight=p->weight;
             p->weight=m;
             q=p;
         }
         p=p->next;
     }while(p!=NULL);
    
    return q;

 }



 void  main(void)

 { 
     struct student *p,*q,*head;
     head=creat();
     p=search(head);
     printf("%s%f%ld",p->high,p->weight,p->name);
     q=find(head);
     printf("%s%f%ld",p->high,p->weight,p->name);
     
     

 }

scanf("%s%f%ld",&stud->high,&stud->weight,&stud->name);这一句有问题！

看不明白哪有问题

创建的时候内层循环没有结束语句啊

我帮你改了一部分，剩下的是类似的，你自己再看看，有问题再讨论

#include <stdio.h>
#include <stdlib.h>
struct student
{    char name[8];
     float high;
     long int weight;
     struct student *next;
};
     int n,i;
struct student *creat()//创建链表
{
      i=1;
     struct student *p,*head,*stud;
     head=NULL;
     stud=head=(struct student *)malloc(sizeof(struct student));
     printf("请输入学生 %d 的身高体重姓名:",i);
     scanf("%f%ld%s",&stud->high,&stud->weight,stud->name);
   while(stud->name!="over") //以姓名为over作为输入链表结束标志
     { p= (struct student *)malloc(sizeof(struct student));
       stud->next=p;
       stud=p;
       scanf("%d%ld%s",&p->high,&p->weight,p->name);
     }
      p->next=NULL;
      return(head);
}
struct student * search(struct student *head)//找出高度最高的那个学生
{ 
     struct student *p,*q,*t;
     p=head;
     while(p!=NULL&&p->next!=NULL)
     {
         if(p->high>=p->next->high)
           t=p;
           p=p->next;
     }
         return t;
}

void  main(void)
{
     struct student *p,*h;
     h=creat();
     p=search(h);
     printf("%f%ld%s",p->high,p->weight,p->name);
     /*q=find(h);
     printf("%s%f%ld",p->high,p->weight,p->name);*/
}

楼上的   你往你的程序里面全输进去0  看看是什么样的   

#include <stdio.h>
#include <stdlib.h>

struct student
{
    char name[8];
    float high;
    long int weight;
    struct student *next;
};

int n,i;

struct student *creat()//创建链表
{

    struct student *p,*head,*stud;
    int r;
    

    i=1;
    head=NULL;
    stud=p=(struct student *)malloc(sizeof(struct student));
    printf("请输入学生 %d 的身高体重姓名:",i);
    r=scanf("%f %ld %s",&stud->high,&stud->weight,&stud->name);
    if(r!=3)
    {
        printf("input error!\n");
        exit(1);
    }

    while(stud->high!=0)
    {
        n++;
        if(n==1)
        { 

            head=stud;
            head->next=NULL;
        }
        else
            p->next=stud;
        p=stud;
        stud=(struct student *)malloc(sizeof(struct student));
        printf("请输入学生 %d 的姓名身高体重:",++i);
        r=scanf("%f %ld %s",&stud->high,&stud->weight,&stud->name);
        if(r!=3)
        {
            printf("input error!\n");
            exit(1);
        }       

    }
    p->next=NULL;
    return(head);
}


struct student * search(struct student *head)//找出高度最高的那个学生
{ 

    struct student *p,*t;
    //float k;

    t=p=head;
    do
    {
        if(t->high < p->high)
        {
            t=p;
        }
        p=p->next;
    }while(p!=NULL);
        return t;
}

struct student * find(struct student *head)//找出体重最重的那个学生
{
    struct student *p,*t;
    //int m;

    t=p=head;
    do
    {
        if(t->weight<p->weight)
        {
            t=p;
        }
        p=p->next;
    }while(p!=NULL);
  

    return t;
}


void  main(void)
{
    struct student *p,*q,*head;

    head=creat();
    if(n==0)
    {
        exit(1);
    }
    p=search(head);
    printf("%f %ld %s\n",p->high,p->weight,p->name);
    q=find(head);
    printf("%f %ld %s\n",q->high,q->weight,q->name);   

}

这个程序好奇怪！

额。。。有问题！让我再改改！

嗯，请大侠指点了！！谢谢！！
