项目描述：
编写简易通讯录，要求使用“链表”这种存储结构，并附带相关操作。
需要功能：
1、使用链表存储联系人的相关信息，包括姓名、性别、电话号码、注释等，链表形式不限（推荐使用单链表，推荐事先准备一些数据）
2、有输出通讯录全部信息的功能
3、有清空通讯录的功能
4、有用户交互界面
5、有插入新联系人信息的功能
6、有查找联系人的功能，包括“按姓名查找”和“按电话号查找”两种
7、有删除联系人的功能，包括“按姓名删除”和“按电话号删除”两种
8、有按性别筛选联系人信息的功能
具体功能请参考示例程序
评分标准：
60+：独立完成，代码运行无错误，具备功能1~3
70+：独立完成，代码运行无错误，具备功能1~4
80+：独立完成，代码运行无错误，具备功能1~7，程序能针对非法输入报错
90+：独立完成，代码运行无错误，具备全部功能，程序能针对非法输入报错，代码书写规范，可读性强，程序与用户的交互性好
