顺序表的初始化和建立函数的调用为什么会报错呢

Question

#include
#include

#define ERROR -1
#define MAX 100

typedef int Status;

typedef int ElemType;

//设计

typedef struct
{
ElemType data[MAX];
int length;
}SqList;

//初始化
void InitList(SqList*&L)
{
L = (SqList *)malloc(sizeof(SqList));
int length = 0;
}
//创建
Status CreateList(SqList& L)
{
int n;
printf("输入插入的个数\n");
scanf_s("%d", &n);
if (n > MAX) return ERROR;
for (int i = 0; i < n; i++)
{

int tmp;
scanf_s("%d", &tmp);
L.data[i] = tmp;
}

}

//插入

//删除

//查找

//判断是否空

//长度
int Length(SqList L)
{
return (L.length);
}

//输出顺序表

void show(SqList L)
{
for (int i = 0;i < Length(L);i++)
{
printf("%d", L.data[i]);
}
}

int main()
{
int status;

SqList L;
InitList(*&L);
status = CreateList(&L);
show(L);
return 0;

}
