通讯录管理系统

通讯录管理系统

添加联系人功能：联系人上限1000人，信息（姓名、性别、年龄、联系电话、住址）

实现步骤：
1.设计联系人结构体
2.设计通讯录结构体
3.main函数中创建通讯录
4.封装添加联系人函数
5.测试添加联系人功能

关于清屏操作：
system("pause"); //按任意键继续
system("cls"); //清屏

删除联系人：
1.检测是否存在联系人
2.封装删除联系人
3.测试删除联系人功能

源码如下：

#include<iostream>
#include<string>
#include<iomanip>
using namespace std;
#define MAX 1000   //最大人数

//联系人结构体
struct Person
{
    string m_Name;   //姓名
    int m_Sex;   //性别 1 - 男 2 - 女
    int m_Age;   //年龄
    string m_Phone;   //电话
    string m_Address;   //地址
};

//通讯录的结构体
struct Addressbooks
{
    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
};

void showMenu();  //菜单函数
void addPerson(Addressbooks* abs);  //添加联系人
void showPerson(Addressbooks* abs);  //显示所有联系人
int isExist(Addressbooks* abs, string name);  //检测联系人是否存在，参数一 通讯录 参数二 对比姓名
void deletePerson(Addressbooks* abs);  //删除指定联系人
void findPerson(Addressbooks* abs);   //查找指定联系人信息
void modifyPerson(Addressbooks* abs);  //修改指定联系人的信息
void cleanPerson(Addressbooks* abs);   //清除所有联系人

int main()
{
    // 创建通讯录结构体变量
    Addressbooks abs;
    //初始化通讯录中当前人数
    abs.m_Size = 0;

    int select = 0;
