Question

《数据结构》课程设计题目急急！！！！

为了实现通讯录管理的几种操作功能，首先设计一个含有多个菜单项的主控菜单程
序，然后再为这些菜单项配上相应的功能。

【设计要求】
1.菜单内容
程序运行后，给出6个菜单项的内容和输人提示：
1．通讯录链表的建立
2．通讯者结点的插人
3．通讯者结点的查询
4．通讯者结点的删除
5．通讯录链表的输出
6．通讯录链表的导入
0．退出管理系统
请选择0-6

2．设计要求
（1）使用数字0-6来选择菜单项，其他输入则不起作用。
（2）功能“6．通讯录链表的导入”是指，从硬盘的“通讯录.txt”文件记录中导入通讯录的数据。
问题补充：为实现通讯录管理的
现在提升到30了可以了吧,就那么多了,都给你了.
希望你可以快一点,有急用.谢谢!!
对了是用C语言编的哦.
