一个链表的问题

#include <stdio.h>
#include <stdlib.h>
struct node
{
int num;
struct node *next;
};
int main()
{
struct node *creat();
void print();
struct node *head;
head=NULL;
head=creat(head);
print(head);
return 0;
}
struct node *creat(struct node *head)
{
int n;
struct node *p1=NULL,*p2=NULL;
printf("\n Please input a integer(>0),if input -1 then exit:\n");
scanf("%d",&n);
while(n>0)
{
p1=(struct node*)malloc(sizeof(struct node));
p1->num=n;
p1->next =NULL;
if(head==NULL)
head=p1;
else
p2->next=p1;
p2=p1;
scanf("%d",&n);
}
return head;
}
void print(struct node *head)
{
struct node *temp;
temp=head;
while(temp!=NULL)
{
printf("%6d",temp->num);
temp=temp->next ;
}
}
哪位大侠帮我看看，在vc++2008上运行有两个错误，怎么解决
error C2660: “creat”: 函数不接受 1 个参数
error C2660: “print”: 函数不接受 1 个参数

int main()
{
struct node *creat(struct node *);
void print(struct node *);

/*
int main() 
{ 
struct node *creat(); 
void print(); 
*/
struct node *creat(); 
void print(); 
int main() 
{ 

函数声明放错地方了
