本文实例为大家分享了C++实现简单的通讯录管理系统的具体代码，供大家参考，具体内容如下
案例描述：
通讯录是一个可以记录亲人、好友信息的工具。
本教程主要利用C++来实现一个通讯录管理系统
系统中需要实现的功能如下：
- 添加联系人：向通讯录中添加新人，信息包括（姓名、性别、年龄、联系电话、家庭住址）最多记录1000人
- 显示联系人：显示通讯录中所有联系人信息
- 删除联系人：按照姓名进行删除指定联系人
- 查找联系人：按照姓名查看指定联系人信息
- 修改联系人：按照姓名重新修改指定联系人
- 清空联系人：清空通讯录中所有信息
- 退出通讯录：退出当前使用的通讯录
#include<iostream>
#include<string>
using namespace std;
#define MAX 1000 //通讯录总人数，可以修改
//联系人信息结构体
struct Person
{
string name;
string sex;

int number;
string address;
};
//通讯录结构体
struct addressbook
{
struct Person personArray[MAX]; //通讯录中保存的联系人数组
int m_Size; //通讯录中人员个数
};
