完整的通讯录管理系统,了能够实现:添加联系人,显示联系人,删除联系人,查找联系人,修改联系人,清空联系人,退出通讯录等操作.全面的运用了C++基础知识.
// 封装函数显示该界面 如 void showMenu()
// 在main函数中调用封装好的函数
#include <iostream>
using namespace std;
#include <string>
#define MAX 1000
//设计联系人的结构体
struct Person
{
string m_Name;//姓名
int m_Sex;//性别 1.男 2.女
int m_Age;//年龄
string m_Phone;//电话号
string m_Addr;//住址
};
struct Addressbooks
{
//通讯录中保存的联系人数组
struct Person personArray[MAX];
//通讯录中当前记录联系人个数
int m_Size;
};
//1.添加联系人
void addPerson(Addressbooks*abs)

//姓名

//如果输入有误,重新输入
