c++實現簡單通訊錄系統（黑馬課程）

程式碼非原創，程式碼非原創，程式碼非原創！發在網上的原因僅僅是學c++時想起了自己大一做課設時候的無助感，所以希望能夠幫助做課設的同學。此程式碼雖然是c++實現，但是很方便就可以改成c語言，如果有人改c語言實現的遇到問題，可以評論或者私聊我。
最後給查程式碼時看到的同學一些建議，此程式碼是江湖救急用的，如果你剛開始課設，那我建議你自己能夠認真思考一下課設如何實現，不管後面你是否選擇程式設計行業，通過課設鞏固一下自己學過的知識，順便瞭解一下程式設計思想也是極好的。
此程式爲黑馬C++免費課程上面的程式碼復現（PS：復現=照着課件敲，個人已經成功執行。），原課程鏈接。如果需要詳細的課件可以去上述鏈接獲取，或者在這篇文章下評論或者私聊我。同時有什麼問題也歡迎大家在評論區討論。

程式碼執行環境：
win10，vs2019.

#include<iostream>
#include<string>
using namespace std;

#define MAX 1000 //最大人數

//聯繫人結構體
struct Person
{
	string m_Name; //姓名
	int m_Sex; //性別：1男 2女
	int m_Age; //年齡
	string m_Phone; //電話
	string m_Addr; //住址
};

//通訊錄結構體
struct Addressbooks

	struct Person personArray[MAX]; //通訊錄中儲存的聯繫人陣列
	int m_Size; //通訊錄中人員個數

//1、新增聯繫人資訊
void addPerson(Addressbooks* abs)
