哪位大侠帮小弟我看看，双链表如何编译不过去呀

哪位大侠帮我看看，双链表怎么编译不过去呀?
#include "stdafx.h"
#include "iostream.h"


class DoubleNodeList
{
public:
int floor;
class DoubleNodeList *prior;
class DoubleNodeList *next;
}DoubleList; //双链表的结构定义 //定义双链表的节点类型。

DoubleList *CreatList(int n) //函数为指针类型，使其返回值为指针值，实际返回链表的头指针，返回类型为class DoubleNodeList类型数据。
{
DoubleList *pre, *head;
int i;
head = new DoubleList;
head->floor=1;
head->prior=NULL;
head->next=NULL;
  pre=head;
for(i=0; i<n; i++)
{
s = new DoubleList;
pre->next=s; //指定后继节点
cout << "输入数字：" << endl;
cin >> s->floor;
s->prior=pre; //指定前驱节点
s->next=NULL;
pre = s; //修改当前指针的指针值。
}
pre->next = NULL;

return head; //返回链表的头指针
}



int main(int argc, char* argv[])
{
return 0;
}









[解决办法]
编译过去了，参考一下吧

C/C++ code
