C语言顺序表的删除操作，后面主函数的调用老是错！

#include <malloc.h>
#include <stdio.h>
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
typedef struct{
int *elem;
int length;
int listsize;
}Sqlist;

Sqlist* InitSqlist()
{
Sqlist * L=NULL;
L=(Sqlist*)malloc(sizeof(Sqlist));//L只是个指针，要指向一个Sqlist.
L->elem=(int *)malloc(LIST_INIT_SIZE*sizeof(int));
L->length=0;
L->listsize=LIST_INIT_SIZE;
return L;
}
void DisplaySqlist(Sqlist* L2)
{
int i;
for(i=0;i<L2->length;i++)//去掉-1,
{
printf("%d ",L2->elem[i]);
}

}

Sqlist* List_Insert_Sq(Sqlist* L3,int i,int e)
{
int * newbase,*p,*q;
if(i<1||i>L3->length+1)return L3;
if(L3->length>=L3->listsize)
{
newbase=(int*)realloc(L3->elem,(L3->listsize+LISTINCREMENT)*sizeof(int));
if(!L3->elem) return L3;
L3->elem=newbase;
L3->listsize+=LISTINCREMENT;
}
q=&(L3->elem[i-1]);
for(p=&(L3->elem[L3->length-1]);p>=q;--p) *p=*(p+1);
*q=e;
++L3->length;
return L3;
}
Sqlist* List_Delete_Sq(Sqlist* L4,int i,int e)
{
int *p,*q;

q=&(L4->elem[i-1]);
for(p=&(L4->elem[L4->length-1]);p>=q;--p) *(p+1)=*p;
*q=e;
++L4->length;
return L4;
}

void main()
{
Sqlist* L1;
Sqlist* i,e;
L1=InitSqlist();
L1=List_Insert_Sq(L1,1,1);
L1=List_Insert_Sq(L1,2,3);
L1=List_Insert_Sq(L1,3,5);
L1=List_Delete_Sq(L1,i,e);
DisplaySqlist(L1);

}
我把主函数里德，就你说的那个改为void main()
{
Sqlist* L1;
L1=InitSqlist();
L1=List_Insert_Sq(L1,1,1);
L1=List_Insert_Sq(L1,2,3);
L1=List_Insert_Sq(L1,3,5);
DisplaySqlist(L1);

} 还是起不到我要删除的作用，帮改成一个能准确运行的删除操作、谢了！
