簡易通訊錄練習（C++實現）

#include <iostream>
#include <string>

using namespace std;

// 設計聯繫人的結構體
struct Person 
{
	string m_Name;
	int m_Sex;   // 1、男   2 女
	int m_Age;
	string m_Phone;
	string m_Addr;
};

// 設計通訊錄的結構體
struct Addressbooks
{
	struct Person personArray[MAX];
	int m_Size;
};


// 1、菜單界面
void showMenu()
{
	cout << "***************************" << endl;
	cout << "*****  1、添加聯繫人  *****" << endl;
	cout << "*****  2、顯示聯繫人  *****" << endl;

// 參數1 通訊錄    參數2  對比姓名

// 7、修改指定的聯繫人信息
