本文实例为大家分享了C++实现通讯录的具体代码，供大家参考，具体内容如下
简介：通讯录由一个拥有者以及通讯信息组成。
基本功能：增删改查
拥有者和通讯信息的基础结构相同，由struct构成

struct Person { int m_id; string m_name; string m_tele;//手机号码可以作为id，但是过于长（11位） //string m_addr; Person& operator = (const Person& r) { if (this == &r) return *this; m_id = r.m_id; m_name = r.m_name; m_tele = r.m_tele; return *this; }}; |
Person：id+姓名+手机号。还可以添加需要的信息，例如：地址、性别
重载了一个=操作符
通讯录建立class AddressList
