c++—通讯录管理系统

Posted 2022-01-03 whp12-cqu

一、运用所学的结构体、地址指针等基础知识，完成通讯录管理系统

二、系统主要有以下6个功能：

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 

 #include<iostream>
 using namespace std;
 #include<string>
 #define MAX 1000
 
 
 //菜单界面
 void showMenu()
 
     cout << "**************************" << endl;
     cout << "*****  1.添加联系人  *****" << endl;
     cout << "*****  2.显示联系人  *****" << endl;
     cout << "*****  3.删除联系人  *****" << endl;
     cout << "*****  4.查找联系人  *****" << endl;
     cout << "*****  5.修改联系人  *****" << endl;

     cout << "*****  0.退出通讯录  *****" << endl;
