UU们这怎么写？有偿急！
编程C语言实现简易版业主信息管理系统，具体要求如下：
1、 要求能够实现业主信息的录入、信息的查询、以及信息的删除三个基本功能；
2、 数据存储：要求使用结构体二维数组存储业主基本信息，基本信息包括（业主姓名，身份证号码，房产单元号），定义结构体时的成员名称和类型可自行确定，程序运行时，要求数组内初始化至少五条数据，数据内容由学生自行确定；
3、 信息的录入功能：要求在程序运行时，由用户交互录入；
4、 信息的查询功能：要求可以实现查询指定姓名的业主基本信息；
5、 信息的删除功能：要求能够删除指定身份证号码的业主的基本信息。

网上找一篇管理系统参考，改成自己的业务。
创建结构体，慢慢根据需求就可写了
1.不使用任何第三方库，只使用最基础的标准库
2.绝大多数使用C语言，少量输入输入会设计C++语句
3.先设计好思路，再编程！
4.所有涉及C语言代码的，都会先讲基础语法知识，再去使用它们。、
5.你不需要已经学过C语言，但你至少要见过C语言的样子。
