非常适合我这个小白练手

通讯录是一个可以记录亲人、好友信息的工具。
系统中需要实现的功能如下：
* 添加联系人：向通讯录中添加新人，信息包括（姓名、性别、年龄、联系电话、家庭住址）最多记录1000人
* 显示联系人：显示通讯录中所有联系人信息
* 删除联系人：按照姓名进行删除指定联系人
* 查找联系人：按照姓名查看指定联系人信息
* 修改联系人：按照姓名重新修改指定联系人
* 清空联系人：清空通讯录中所有信息
* 退出通讯录：退出当前使用的通讯录

#include <iostream>
#include <string>
using namespace std;
#define  MAX  1000
1-----//设计联系人的结构体
struct Person
{
//姓名
string m_Name;
//性别
int m_Sex;
//年龄
int m_Age;
//电话
string m_Phone;
//住址
string m_Addr;
};
2----------//设计通讯录的结构体
struct Addressbooks
{
//通讯录中保存的联系人数组
struct Person personArray[MAX];
//通讯录中当前联系人个数
int m_Size;
};

3------//添加联系人
void addPerson(Addressbooks *abs)
{
//判断通讯录是否已满，满了就不在添加
if (abs->m_Size==MAX)
{
cout << "通讯录已满，无法添加" << endl;
return;
}
else
{
//姓名
string name;
cout << "请输入姓名:" << endl;
cin >> name;
abs->personArray[abs->m_Size].m_Name = name;
//性别
cout << "请输入性别:" << endl;
cout << "1-----男" << endl;
cout << "2-----女:" << endl;
int sex = 0;

while (true)
{
cin >> sex;

}

//年龄
cout << "请输入年龄：" << endl;

//电话
cout << "请输入电话：" << endl;
string phone;
cin >> phone;

//住址
cout << "请输入住址：" << endl;

cin >> address;
abs->personArray[abs->m_Size].m_Addr = address;
//更新通讯录人数
abs->m_Size++;
cout << "添加成功" << endl;
system("pause");
system("cls");//清空屏幕
}
}

4-----//显示所有联系人
void showPerson(Addressbooks * abs)
{
//判断通讯录中人数是否为0
if (abs->m_Size==0)
{
cout << "当前记录为空" << endl;
}
else
{

{
//姓名
cout << "姓名" << abs->personArray.m_Name << "\t";
//年龄
cout << "年龄" << abs->personArray.m_Age << "\t";
//性别
cout << "性别" << (abs->personArray.m_Sex==1?"男":"女")<<"\t";
//电话
cout << "电话" << abs->personArray.m_Phone << "\t";
//住址
cout << "住址" << abs->personArray.m_Addr << endl;
}
}
system("pause");
system("cls");
}

5------//检测联系人是否存在，如果存在，返回联系人所在的数组中的具体位置，不存在返回-1
int isExist(Addressbooks * abs, string name)
{
for (int i = 0; i < abs->m_Size; i++)
{
//找到用户输入的姓名了
if (abs->personArray.m_Name==name)

}

6-------//删除指定联系人
void deletePerson(Addressbooks * abs)
{
cout << "请输入你要删除的联系人" << endl;
string name;
cin >> name;
//ret==-1未查到
//ret！=1查到了
int ret = isExist(abs, name);
if (ret != -1)
{

{
abs->personArray = abs->personArray[i + 1];
}
abs->m_Size--; //更新通讯录的人员数
}
else
{
cout << "查无此人" << endl;
}
}

7--------//查找指定联系人信息
void findPerson(Addressbooks * abs)
{
cout << "请输入你要查找的联系人" << endl;
string name;
cin >> name;
//判断指定的联系人是否在通讯录中
int ret = isExist(abs, name);
if (ret!=-1)

//姓名
cout << "姓名" << abs->personArray[ret].m_Name << "\t";
//性别
cout << "性别" << abs->personArray[ret].m_Sex << "\t";

cout << "年龄" << abs->personArray[ret].m_Age << "\t";
//电话
cout << "电话" << abs->personArray[ret].m_Phone << "\t";

system("pause");
system("cls");

8------------//修改指定联系人信息

{
cout << "请输入你要修改的联系人" << endl;
string name;

int ret = isExist(abs, name);
if (ret != -1)

9----------------//清空所有联系人
void cleanPerson(Addressbooks *abs)
