C++实现通讯录功能
作者：xl拾一
这篇文章主要为大家详细介绍了C++实现通讯录功能，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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
class AddressList {
private:
Person owner;//通讯录拥有者
vector<Person> information;//通讯录：好友的信息组成
public:
AddressList();
AddressList(const Person&, const vector<Person>& info = {});
AddressList(const AddressList&);
void Add(const Person&);//添加一个好友信息至通讯录
void Delete();//通过姓名删除
//通过电话号码删除
void Modify();//输入id 修改姓名and号码
void Search(int);//1:id搜索
//2：姓名搜索
//3：号码指定搜索
void Print()const;
//查看通讯录所有信息：仅显示id和姓名，详细信息输入id查看
};cpp：
#include "AddressList.h"
#include <iostream>
using namespace std;
AddressList::AddressList() {}
AddressList::AddressList(const Person& r, const vector<Person>& info) {
owner = r;
for (const auto& i : info) {
information.push_back(i);
}
}
AddressList::AddressList(const AddressList& r) {
owner = r.owner;
for (const auto& i : r.information) {
information.push_back(i);
}
}
void AddressList::Add(const Person& p) {
//添加一个好友信息至通讯录
//首先确认不存在：id+tele
for (const auto& it : information) {
if (p.m_id == it.m_id) {
cout << "Id已存在，添加失败!\n";
return;
}
else if (p.m_tele == it.m_tele) {
cout << "Telephone已存在，添加失败!\n";
return;
}
}
information.push_back(p);
}
void AddressList::Delete() {
//通过姓名删除
//略：通过电话号码删除
string name;
cout << "姓名："; cin >> name;
cout << "查找到信息如下:";
auto it = information.begin();
