以下贴出我的源代码,其它函数没有问题,可能编译和正常运行,可是sort_link函数就有错误了
#include "stdio.h"
#include "stdlib.h"
struct node
{int data;
 char name[10];
 struct node *next;
};
typedef struct node LINK;
#define MAL (LINK *)malloc(sizeof(LINK))
LINK *creat_link()
{LINK *head,*s,*r;
 r=head=MAL;
 s=MAL;
 printf("PLease input data and name:");
 scanf("%d%s",&s->data,s->name);
 while(1)
   {r->next=s;
   r=s;
   s=MAL;
   printf("Please input data and name:");
   setbuf(stdin,NULL);
   scanf("%d",&s->data);
   if(s->data==-1)
      break;
   setbuf(stdin,NULL);
   scanf("%s",s->name);
  }
 r->next=0;
 return head;
}
void print_link(LINK *head)
{
   if(head->next==0)
      printf("Link is NULL!");
   else
      for(head=head->next;head!=0;head=head->next)
          printf("%d %s\n",head->data,head->name);
}
LINK *sort_link(LINK *head)
{LINK *q,*p,*temp;
  for(q=head;q->next!=0;q=q->next)
         for(p=q->next;p!=0;p=p->next)
                 if(q->next->data>p->next->data)
                  {temp=p;
                    q->next=p->next;
                    q->next=temp;
                    temp->next=p;
                  }/*就是这里了,我总是写错,不知道该怎么改?*/
 print_link(head);
}
main()
{LINK *head;
 head=creat_link();
 print_link(head);
 sort_link(head);
 printf("Enter anykey to exit. . .");
 setbuf(stdin,NULL);
 getchar();
}

求大神啊

额,这个高手那你接下来还是先说说这个sort_link函数吧,我给改成这样了,可是还是不能排序成功
LINK *sort_link(LINK *head)
{LINK *q,*h,*p,*temp;
  int n=0;
  for(q=head;q->next!=0;q=q->next)
          for(h=q,p=q->next;p!=0;p=p->next)
            {if(n)
               {n=0;
                 h->next=temp;
                 temp->next=p;
               }
             if(h->next->data>p->next->data)
              {n=1;
                temp=p;
                h->next=p->next;
              }
             h=p;
            }
 print_link(head);
}
高手帮帮忙好吗

貌似那个输入->name前我没有加&

我->name前没加&

额,那个大神,你这个貌似是交换数据了吧,我要的是交换节点

除了这个能不能再说点什么
