1、系統需求

本文將利用C++來實現一個通訊錄管理系統

系統中需要實現的功能如下：

• 添加聯系人：向通訊錄中添加新人，信息包括（姓名、性別、年齡、聯系電話、家庭住址）最多記錄1000人
• 顯示聯系人：顯示通訊錄中所有聯系人信息
• 刪除聯系人：按照姓名進行刪除指定聯系人
• 查找聯系人：按照姓名查看指定聯系人信息
• 修改聯系人：按照姓名重新修改指定聯系人
• 清空聯系人：清空通訊錄中所有信息
• 退出通訊錄：退出當前使用的通訊錄

#include<iostream>
#include<string>
#define MAX 1000
using namespace std;//設計聯系人結構體
struct Person

};//設計通訊錄結構體
