完整代码：

系统要求

系统中需实现的功能如下：

添加联系人：联系人信息包括（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的信息。

删除联系人：按姓名删除相应联系人。

查找联系人：按姓名进行查找联系人，并显示该联系人的信息。

修改联系人：按姓名修改联系人的相关信息。

清空联系人：清空通讯录中的所有信息。

推出通讯录：退出当前使用的通讯录。

算法描述

功能菜单

封装函数显示该界面

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 << "*****6，清空联系人*****" << endl;
	cout << "*****0，退出通讯录*****" << endl;
	cout << "***********************" << endl;
}

退出功能

根据用户不同的选择，进入不同的功能。

        switch (select)
		{
		case 1://添加联系人
			addPerson(&abs);//利用地址传递可以修改实参
			break;
		case 2://显示联系人
			showPerson(&abs);
			break;
		case 3://删除联系人
			deletePersion(&abs);
			break;
		case 4://查找联系人
			findPerson(&abs);
			break;
		case 5://修改联系人
			modifyPerson(&abs);
			break;
		case 6://清空联系人
			cleanPerson(&abs);
			break;
		case 0://退出通讯录
			cout << "欢迎下次使用！" << endl;
			system("pause");
			break;
		}

添加联系人

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	adderssBooks
{
	struct Person personArray[MAX];
	int m_Size;
};

3，main函数中创建通讯录

//创建通讯录结构体变量
adderssBooks abs;

//初始化通讯录中当前人员个数
abs.m_Size = 0;

4，封装添加联系人函数

void addPerson(adderssBooks* abs)
{
	//判断通讯录是否满了
	if (abs->m_Size == MAX)
	{
		cout << "通讯录已满，无法添加！" << endl;
		return;
	}
	else
	{
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		abs->personArray[abs->m_Size].m_Name = name;

		cout << "请输入性别：" << endl;
		cout << "1——男：" << endl;
		cout << "2——女：" << endl;
		int sex;
		while (true)
		{
			cin >> sex;
			if (sex == 1 || sex == 2)
			{
				abs->personArray[abs->m_Size].m_Sex = sex;
				break;
			}
			else
			{
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入年龄：" << endl;
		int age;
		while (true)
		{
			cin >> age;
			if (age > 0 && age < 200)
			{
				abs->personArray[abs->m_Size].m_Age = age;
				break;
			}
			else
			{
				cout << "年龄要在0~200之间！" << endl;
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入电话：" << endl;
		string phone;
		while (true)
		{
			cin >> phone;
			if (phone.length()==11)
			{
				abs->personArray[abs->m_Size].m_Phone = phone;
				break;
			}
			else
			{
				cout << "友情提醒：电话号码是11位！" << endl;
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入家庭住址：" << endl;
		string adderss;
		cin >> adderss;
		abs->personArray[abs->m_Size].m_Addr = adderss;

		//更新通讯录人数
		abs->m_Size++;
		cout << "添加用户成功" << endl;

		system("pause");
		system("cls");//清屏
	}
}

显示联系人

封装显示联系人函数

void showPerson(adderssBooks* abs)
{
    //判断通讯录是否为空
	if (abs->m_Size == 0)
	{
		cout << "当前记录为空" << endl;
	}
	else
	{
		for (int i = 0; i < abs->m_Size; i++)
		{
			cout << "姓名" << abs->personArray[i].m_Name << "\t";
			cout << "性别" << (abs->personArray[i].m_Sex == 1 ? "男" : "女") << "\t";
			cout << "年龄" << abs->personArray[i].m_Age << "\t";
			cout << "电话" << abs->personArray[i].m_Phone << "\t";
			cout << "住址" << abs->personArray[i].m_Addr << endl;
		}

	}
	system("pause");
	system("cls");//清屏
}

删除联系人

1，封装检测联系人是否为空的函数

int isExist(adderssBooks* abs, string name)
{
	for (int i = 0; i < abs->m_Size; i++)
	{
		if (abs->personArray[i].m_Name == name)
			return i;
	}
	return -1;
}

2，封装删除联系人的函数

void deletePersion(adderssBooks* abs)
{
	cout << "请输入您要删除的联系人：" << endl;
	string name;
	cin >> name;

	//ret == -1 未查到
	//ret != -1 查到了
	int ret = isExist(abs, name);
	if (ret != -1)
	{
		for (int i = ret; i < abs->m_Size; i++)
		{
			abs->personArray[i] = abs->personArray[i + 1];
		}
		abs->m_Size--;
		cout << "删除成功" << endl;
	}
	else
	{
		cout << "查无此人" << endl;
	}

	system("pause");
	system("cls");//清屏
}

查找联系人

封装查找联系人的函数

void findPerson(adderssBooks* abs)
{
	cout << "请输入您要查找的联系人" << endl;
	string name;
	cin >> name;

	int ret = isExist(abs, name);
	if (ret != -1)
	{
		cout << "姓名" << abs->personArray[ret].m_Name << "\t";
		cout << "性别" << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << "\t";
		cout << "年龄" << abs->personArray[ret].m_Age << "\t";
		cout << "电话" << abs->personArray[ret].m_Phone << "\t";
		cout << "住址" << abs->personArray[ret].m_Addr << endl;
	}
	else
	{
		cout << "查无此人" << endl;
	}
	system("pause");
	system("cls");//清屏
}

修改联系人

封装修改联系人的函数

void modifyPerson(adderssBooks* abs)
{
	cout << "请输入您要修改的联系人" << endl;
	string name;
	cin >> name;
    
    //判断联系人是否存在
	int ret = isExist(abs, name);
	if (ret != -1)
	{
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		abs->personArray[ret].m_Name = name;

		cout << "请输入性别：" << endl;
		cout << "1——男：" << endl;
		cout << "2——女：" << endl;
		int sex;
		while (true)
		{
			cin >> sex;
			if (sex == 1 || sex == 2)
			{
				abs->personArray[ret].m_Sex = sex;
				break;
			}
			else
			{
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入年龄：" << endl;
		int age;
		while (true)
		{
			cin >> age;
			if (age > 0 && age < 200)
			{
				abs->personArray[abs->m_Size].m_Age = age;
				break;
			}
			else
			{
				cout << "年龄要在0~200之间！" << endl;
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入电话：" << endl;
		string phone;
		while (true)
		{
			cin >> phone;
			if (phone.length() == 11)
			{
				abs->personArray[abs->m_Size].m_Phone = phone;
				break;
			}
			else
			{
				cout << "友情提醒：电话号码是11位！" << endl;
				cout << "输入有误，请重新输入：" << endl;
			}
		}

		cout << "请输入家庭住址：" << endl;
		string adderss;
		cin >> adderss;
		abs->personArray[ret].m_Addr = adderss;
	}
	else
	{
		cout << "查无此人" << endl;
	}
	system("pause");
	system("cls");//清屏
}

清空联系人

封装清空联系人的函数

只要将通讯录记录联系人的数量置为0，做逻辑清除即可。

void cleanPerson(adderssBooks* abs)
{
	cout << "请问是否要清空所有联系人信息？" << endl;
	cout << "1——是" << endl;
	cout << "2——否" << endl;
	int num;
	cin >> num;
	if (num == 1)
	{
		abs->m_Size = 0;  //逻辑清空
		cout << "通讯录已清空" << endl;
	}
	else
	{
		cout << "按任意键返回！" << endl;
	}
	system("pause");
	system("cls");//清屏
}

完整代码：

主函数：

#include <iostream>
#include <string>
using namespace std;
#include"addressBook.h"

int main()
{
	//创建通讯录结构体变量
	adderssBooks abs;
	//初始化通讯录中当前人员个数
	abs.m_Size = 0;
	//创建用户选择的变量
	int select = 0;
	while (true)
	{
		//菜单调用
		showMenu();

		cin >> select;
		switch (select)
		{
		case 1://添加联系人
			addPerson(&abs);//利用地址传递可以修改实参
			break;
		case 2://显示联系人
			showPerson(&abs);
			break;
		case 3://删除联系人
			deletePersion(&abs);
			break;
		case 4://查找联系人
			findPerson(&abs);
			break;
		case 5://修改联系人
			modifyPerson(&abs);
			break;
		case 6://清空联系人
			cleanPerson(&abs);
			break;
		case 0://退出通讯录
			cout << "欢迎下次使用！" << endl;
			system("pause");
			break;
		}
	}
	system("pause");
	return 0;
}

2，头文件

#include <iostream>
#include <string>
using namespace std;
#define MAX 1000

//联系人结构体
struct Person
{
	string m_Name;
	int m_Sex;
	int m_Age;
	string m_Phone;
	string m_Addr;
};

//通讯录结构体
struct	adderssBooks
{
	struct Person personArray[MAX];

void deletePersion(adderssBooks* abs);
//查找联系人
void findPerson(adderssBooks* abs);
