【C语言】通讯录实现。

实现一个通讯录：

通讯录用来存放1000个人的信息，每个人的信息包括：

姓名、性别、年龄、电话、住址

提供方法：

（1）添加联系人信息

（2）删除指定联系人信息

（3）查找指定联系人的信息

（4）修改指定联系人信息

（5）显示所有联系人信息

（6）清空所有联系人

实现方法：

#include <stdio.h>
#include <string.h>

#define MAX 1000
#define NAME_LEN 10
#define SEX_LEN 5
#define PHONE_LEN 20
#define ADDRESS_LEN 30
