C++做一个简单的通讯录管理系统

功能

仅仅在内存上实现简单的通讯录，不涉及数据库，程序终止数据不存

1. 添加联系人
2. 显示联系人
3. 删除联系人
4. 查找联系人
5. 修改联系人
6. 清空联系人
7. 退出通讯录

对应子函数

void showMenu()//显示菜单
void addPerson(Addressbooks *p)//添加联系人
void showPerson(Addressbooks* p)//显示联系人
void deletePerson(Addressbooks* p)//删除联系人
void findPerson(Addressbooks* p)//查找联系人
void changePerson(Addressbooks* p)//修改联系人
void cleanPerson(Addressbooks* p)//清空联系人

完整代码（一个cpp文件就可以）

#include <iostream>
#include <string>

using namespace std;

#define MAX 500//联系人最大数量

//联系人结构体
struct Person
{
    string m_Name="";

    string m_Phone="";
    string m_Addr="";
};

//通讯录结构体
struct Addressbooks {
    //通讯录中保存的联系人数组
    struct Person personArray[MAX];
    //通讯录中记录的联系人个数
    int m_Size;
};
