链表的程序编译失败,拜求高手解疑, 编译器是VC++ 6.0

#include  "stdio.h"

typedef        struct     LNode
{

    int        key;
    struct    LNode    *  nextptr;

}    LNode, * LinkList;







int       main()
{
           

           int        n = 3;
           int        i;
           LinkList        L;
           LinkList     p;
            
   
            L = (      LinkList     ) malloc    (    sizeof    (    LNode    )    );
            L -> nextptr = NULL;
            for (    i = 1;    i <= n; i ++ )
            {
   
                p = (    LinkList    ) malloc (    sizeof    (    LNode    )    );
                scanf (    "%d", & p -> key    );
                p -> nextptr = L -> nextptr;
                L -> nextptr = p;
   
            }
            p = L -> nextptr;
            while (    p   )
            {
               
                printf ( "\n%d", p -> key   )   ;
                p = p -> nextptr;
               
            }
            getch();
            return  0;
