[求解!]打印链表元素主程序出错

Question

主程序如下;

 #include "list.h"
#include <stdio.h>
#include <stdlib.h>

struct Node
        {
            ElementType Element;
            Position    Next;
        };

int main(){
    List list= malloc( sizeof( struct Node ) );
    Position P=list;
    for(int i=0;i<10;i++){
        Insert(i,list,P);
        P=P->Next;
    }
    P=list->Next; //注意不是P=list
    for(int j=1;j<=10;j++){
        printf("%d\n",P->Element);
        P=P->Next;
    }

    if(!IsEmpty(List list))
       printf("not empty");

    Delete(ElementType 4,List list);
    P=list->Next; 
    for(int j=1;j<=10;j++){
        printf("%d\n",P->Element);
        P=P->Next;
    }    

    return 0;
}

编译时出错如下:

 zoegreen@zoegreen-Lenovo-IdeaPad-Y470:~/桌面$ gcc main.c list.c -o list
main.c: In function ‘main’:
main.c:24:17: error: expected expression before ‘List’
     if(!IsEmpty(List list))
                 ^
main.c:27:12: error: expected expression before ‘ElementType’
     Delete(ElementType 4,List list);
            ^
main.c:27:12: error: too few arguments to function ‘Delete’
In file included from main.c:1:0:
list.h:16:14: note: declared here
         void Delete( ElementType X, List L );
              ^

求大神解答~谢谢~
