本文介绍了一个简易的通讯录管理系统的设计与实现，该系统使用C语言编写，具备添加、查询、修改、删除联系人及排序等功能，并针对现有不足提出了改进方向。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

实现功能有：

1.新建，添加联系人，在达到上限时输出book full！(存储上限可以通过改变宏定义里MAXSIZE的值来实现，为了测试方便，目前的 MAXSIZE = 3)

2.查看当前通讯录内所有联系人

3.以名字为索引查找联系人

4.以名字为索引修改联系人

5.以名字为索引删除联系人

6.按名字ASCII码值从小到大排序

7.按下按键esc退出

8.十分贴心地把字体调成了红色。

不足：

1.选择功能时必须键盘输入选项然后回车才有效。预想操作应该是按下对应按键直接实现功能，不用按回车，也不会在屏幕显示按下了哪个按键。

2.没能实现在添加联系人时，和上面一样按ESC不回车不显示直接退出。

3.在打印联系人列表时用sleep()函数暂留3秒，没能实现在打印出联系人列表后按任意键退出当前画面。、

4.输入的联系人名字是中文时，不会按拼音顺序排序

5.在每个功能界面快刷新的时候输入字符会影响到下次功能选择。

6.删除功能不完善，删除后再打印联系人信息列表，信息展示不对。

7.没有输入错误反馈不完善
