本文总结了使用C++编程实现的一个简易学生通讯录，涵盖了C++通讯录的设计与实现，包括关键功能和结构。
用c++写的简易学生通讯录
http://blog.youkuaiyun.com/yuzhihui_no1/article/details/43530445昨天我一大学室友找到我说他亲戚要个学生通讯录程序，一定要c++来写，而他是学Java的，对c++的基本语法都忘干净了。因为我是做c方面开发的，所以问我能不能搞定。虽然我也半年多没用c++写过东西了，但作为室友怎么能拒绝呢，再个看了下他的需求感觉挺简单的（没涉及到数据库操作），于是就应承下来了。
他给我的需求是这样的：
学生通讯录系统
学生通信录信息包括：姓名、学号、年龄、性别、家庭住址、联系电话、寝室号等信息。
系统以菜单方式工作，使之能提供以下功能：：
学生通信录信息的输入
学生的通信录信息删除和修改
学生的通信录信息查询和统计功能
学生的通信录信息输出显示
而且数据都保存在内存中；
我在Linux下用了半上午时间给他写了个简易的通讯录程序，下面我把代码贴出来，希望可以给那些大一大二想写这个程序的同学一点思路。其中不规范的地方还望大家指出了（因为为了尽快完成功能，所以一些规范就没太注意），谢谢！

程序基本就是这样的，在Linux系统上测试通过，没问题。在其他系统上应该没有大问题，如果有的话就是头文件的问题（听室友说在mac上sleep()函数是没有的，Windows下要添加一个头文件，具体什么头文件需要的可以百度下）；
程序还有个问题，就是在menu()函数中输入值给number时，如果你输入字符就会出现死循环（这个死循环不是因为while(1)造成的，如果正常死循环，每循环一次就会等待用户输入一个值），在我预计中不会出现这个问题的，因为输入字符也是转化成ascii码，然后也会被剔除的。可惜，不是这样，我打印了下number（当输入字符A时），结果却是0，而不是64；还有当输入学生信息时，如果在id输入时，不小心输入名字时（其实就是字符串）也会出现未知的错误。查了资料说是c++中类型不能混用，本应该要有防止这种失误操作的处理方法，但我实验了下，没成功，如果谁有好的办法希望可以告诉我一声，共同学习嘛。谢谢！

C++通讯录
http://www.cnblogs.com/orangebook/p/3514452.htmlC++通讯录1.0
历时一天，终于把通讯录写好了。
项目要求：
复制代码
编写一个通讯录管理程序。
有一已存在的通讯录文件，数据内容为各联系人信息。
每个联系人信息的组成部分为：
姓名、电话号码和住址
等个人基本信息，
并假设已有两个联系人。
并假设已有两个联系人。
（1）输出联系人：打开通讯录文件并显示其中的数据；
（2）添加联系人；
（3）查找联系人：利用字符串函数，按“姓名”查找；
（4）修改联系人：可以修改该联系人的任一个信息；
（5）保存到文件：将操作结果保存到已存在的通讯录文件；
（6）用子函数实现各个子功能。
复制代码
通讯录的
核心类：VAdressBook
数据库：SQLite
编程语言：C++
常用函数：sprintf
常用SQLiteAPI函数：sqlite3_exec
还存在技术问题：重命问题(在翻译完SQLite高级教程后可解决)
未使用UI（计划使用wxWidgets或Java的图形库 或 SDL）
还存在的程序设计问题：使用了简单工厂设计模式，扩展性不佳，维护性不佳。（重构代码）
现在的皱形效果图为：
