用c语言编写通讯录

题目三 通讯录
1. 设计要求：
基本功能：
a) 添加个人信息
b) 查询个人信息
c) 删除个人信息
d) 修改个人信息
e) 信息排序
f) 输出全部信息
拓展功能：
采用文件形式对通讯录进行操作，包括：
a) 写入文件
b) 读取文件
创新（自拟）功能：
程序实现的其它功能由个人自拟。

2. 设计要求具体说明
通讯录至少应该有以下数据项：姓名，家庭住址，手机号码，邮编，E-mail。
输入信息时要检查数据项手机、邮编、E-mail的合法性，手机号码：11位数字；邮编：6位数字；E-mail：包含@字符，且@两边都非空。
对通讯录应该包含有以下操作(包括基本功能和拓展功能)：
a) 向通讯录中添加信息；
b) 在通讯录中按姓名或手机号查找个人信息；
c) 删除通讯录中的个人信息；
d) 修改通讯录中的个人信息，并保存入文件；
e) 按不同数据项排序后列表输出通讯录中所有人的信息。通讯录中记录的数量没有限制。
f) 将通讯录中的数据写入文件和从文件读入数据。
程序启动时先从文件读入数据，如果文件中没有数据则给出提示；写入文件时有两种方式，一为覆盖所有原有的内容; 二为只将本次操作所修改的个人信息写入文件
g) 程序启动时先从文件读入数据，如果文件中没有数据则给出提示退出程序。

3. 设计提示
定义合适的结构体类型，使用链表或数组的方式组织数据。
