单链表逆序如何出不来

单链表逆序怎么出不来
# include <stdio.h>
# include <malloc.h>
# define null 0
typedef struct node {
int data;
struct node *next;}lnode,*linklist;
linklist creat(linklist head, int n)  
  {linklist p; 
int i;
scanf("%d",&n);
  head=(linklist)malloc(sizeof(lnode));
head->next=null ;  
  for(i=n;i>0;i--)
{p =(linklist)malloc(sizeof(lnode));
scanf("%d",&p->data);
p->next=head->next ;
head->next=p ;}
  return head;
}
void print(lnode* p) 
{printf("输出单链表为：");
while(p->next!=null)

{
printf("\n%d\n",p->next->data);

p=p->next;}
}
linklist invert(linklist head)
{
linklist s,p;
s=(lnode*)malloc(sizeof(linklist));
s->next=null;
p=head;
while(p)
{p->next=s;s=p;
p=p->next;
return s;}
} 
void print2(lnode* s) 
{printf("输出单链表逆序为：");
while(s->next!=null)

{
printf("\n%d\n",s->next->data);

s=s->next;}
}
void main()
{ linklist head,s;

head=null;s=null;int n;
printf("请输入元素个数及元素值\n");


head=creat(head,n);
print(head);
head=invert(head);
print2(s);
}

[解决办法]
linklist invert(linklist head)
{
 linklist s,p;
 s=(lnode*)malloc(sizeof(linklist));
 s->next=null;
 p=head;
 while(p)
 {p->next=s;s=p;
 p=p->next;
 return s;}
}


==>

linklist invert(linklist head)
{
 linklist s,p,q;
 s=head;
 p=head;
 while(p)
 {
 q=p->next;
 p->next=s;s=p;
 p=q;
}
 return s;
}

刚巧昨天写了一个，仅供参考

C/C++ code
