麻烦诸位帮忙看看以下用线性表实现的通讯录 错在哪里？
#include <stdio.h>
#include <stdlib.h>
#include <malloc.h>
#define LIST_INIT_SIZE 100
#define LISTINCREMENT 10
#define POSITION a->elem
typedef struct{ // 联系人--结构体
int num;
char name[20];
char sex[10];
char tel[20];
char adress[50];
}Contact;
typedef struct{
Contact *elem;
int curlen;
int listsize;
}List;
//**程序操作基本函数定义
int Initial(List *a); //初始化定义
void Input(List *a); //输入联系人信息
void Input2(List *a,int n); //辅助函数
void Change(List *a); //更改联系人信息
void Insert(List *a); //插入联系人
void Delete(List *a); //删除联系人
void Num_Check(List *a); //按序号查找联系人
int Name_Check(List *a); //按姓名查找联系人
void Print(List *a); //输出通讯录中所有联系人信息
//主函数
int main()
{
int m,test;
List *Sq;
