功能

僅僅在記憶體上實現簡單的通訊錄，不涉及資料庫，程式終止資料不存

1. 新增聯絡人
2. 顯示聯絡人
3. 刪除聯絡人
4. 查詢聯絡人
5. 修改聯絡人
6. 清空聯絡人
7. 退出通訊錄

對應子函式

void showMenu()//顯示選單
void addPerson(Addressbooks *p)//新增聯絡人
void showPerson(Addressbooks* p)//顯示聯絡人
void deletePerson(Addressbooks* p)//刪除聯絡人
void findPerson(Addressbooks* p)//查詢聯絡人
void changePerson(Addressbooks* p)
 
//修改聯絡人
void cleanPerson(Addressbooks* p)//清空聯絡人
