本文例項為大家分享了C++實現簡易通訊錄的具體程式碼，供大家參考，具體內容如下

#include <iostream>
#include <string>
#define MAX 1000
using namespace std;

// 設計聯絡人的結構體
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;
};

 cout << "***** 6、清空聯絡人 *****" << endl;
