C++实现通讯录管理系统

#include <iostream>
using namespace std;
#include <string>

#define MAX  1000

//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
//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;

//添加联系人实现步骤：
//1. 设计联系人结构体
struct  Person
{
    string m_Name;
    int m_Sex;
    int m_Age;
    string m_Phone;
    string m_Addr;
};

//2. 设计通讯录结构体
struct AddressBook
{
    //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;
};

//4. 封装添加联系人函数
void addPerson(AddressBook *abs)
{
    //判断通讯录是否已满，如果满了就不再添加
    if (abs->m_Size == MAX )
    {
        cout << "通讯录已满，无法添加！" << endl;
        return;
