手机在人们生活中越来越普遍了，每个人的手机中都有一个通讯录，那么今天我就用c语言给大家实现一个简易版的手机通讯录，要求如下：  
实现一个通讯录，通讯录可以用来存储1000个人的信息，每个人的信息包括： 姓名、性别、年龄、电话、住址

提供方法如下：

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
7.  以名字排序所有联系人
8.  保存联系人到文件
9.  加载联系人

具体实现过程如下，主要是应用结构体，简单易懂

#define _CRT_SECURE_NO_WARNINGS
    #include<stdio.h>
    #include<string.h>
    #include<assert.h>
    #include<stdlib.h>
    
    #define NameMax 20
    #define SexMax 3
    #define TelMax 11
    #define AddressMax 20
    #define PeopleMax 1000
    
    typedef char Persontype;
    
    typedef struct PERSON
    {
    	Persontype Name[NameMax];//  姓名
    	Persontype Sex[SexMax];  // 性别
    	int Age;          // 年龄
    	Persontype Tel[TelMax]; //联系方式
    	Persontype Address[AddressMax]; //地址
    
    }Person;
    
    typedef struct BOOK
    {
    	Person Data[PeopleMax];//Address_Book结构体最大存储容量
    	int count;    //当前已存储人数
    }Book;
    
    void Initbook(Book* people); //初始化
    
    void show_person(Book* people);//打印
    
    void Add_person(Book *people);// 增加成员
    
    void Del_person(Book* people);//删除成员
    
    int Find_person(Book* people);//查找成员
    
    void Change_person(Book* people);//修改成员
    
    void BubbleSort_person(Book* people);//冒泡排序
    
    
    
    //初始化
    void Initbook(Book* people)
    {
    	people->count = 0;
    }
    
    //打印
    void show_person(Book* people)
