c语言数据结构的问题，困扰已久，寻求指导！
一个顺序表的建立程序，在vc6下编辑的！在仔细查找了若干遍后还是没发现错误的原因，希望高手给指点迷津！！
#include <stdio.h>
#include <stdlib.h>
#define OVERFLOW -2
#define OK 1
#define ERROR 0
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
typedef int ElemType;
typedef int Status;
typedef struct
{
ElemType *elem;
int length;
int listsize;
}SqList;
Status InitList_Sq(SqList &L)
{
L.elem=(ElemType *)malloc (LIST_INIT_SIZE*sizeof(ElemType));
if(!L.elem)
exit(ERROR);
L.length=0;
L.listsize=LIST_INIT_SIZE;
return OK;
}
void CreateList(SqList &L,int len)
{
if(len>LIST_INIT_SIZE)
{
L.elem=(ElemType *)malloc (L.elem,len*sizeof(ElemType));
L.listsize=len;
}
printf("请输入顺序表元素：\n");
for(int i=0;i<=len-1;i++)
{
scanf("%d",L.elem[i]);
}
L.length=len;
printf("建立顺序表为：\n");
for(i=0;i<=len-1;i++)
{
printf("%d",L.elem[i]);
}
printf("\n顺序表一共%d个元素。\n",L.length);
}
void main()
{
SqList L;
int Sqlen;
if(!InitList_Sq(L))
{
printf("初始化顺序表失败！\n");
exit(ERROR);
}
printf("输入顺序表个数：");
scanf("%d",Sqlen);
CreateList(L,Sqlen);
}
错误提示如下：

[解决办法]
L.elem=(ElemType *)malloc (L.elem,len*sizeof(ElemType));
==》
L.elem=(ElemType *)malloc (len*sizeof(ElemType));

发我qq或文件，我给你调试，先记下
[解决办法]
我运行就一个问题啊：
realloc()函数使用错误，
这个函数有两个参数一个指针，一个是大小，
指针应该指向想扩展的变量。
所以应该是：
realloc(&L,len*sizeof(ElemType));
关于realloc（）的用法可以看一下：
