1.初始化

显示菜单界面

void show()
{
	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  ******" << endl;
}

设计联系人结构体

//设计联系人结构体
struct person
{
	string name;
	int sex=0;  //男1 女2
	int age=0;
	string phone;
	string addr;
 };

通讯录结构体

#define max 100
//通讯录结构体
struct books
{
	struct person arr[max];
	int size=0;  //联系人个数
};

2.添加联系人

void addperson(books* abs)
{
	if (abs->size <= max)
	{
		string name;
		cout << "请输入姓名： " << endl; cin >> name;
		abs->arr[abs->size].name = name;

		cout << "请输入性别 男1 女2" << endl;
		while (1)
		{
			int sex = 0; cin >> sex;
			if (sex == 0 || sex == 1)
			{
				abs->arr[abs->size].sex = sex;
				break;
			}
			else
				cout << "输入有误，请重新输入" << endl;
		}

		cout << "请输入年龄" << endl;
		int age = 0; cin >> age;
		abs->arr[abs->size].age = age;

		cout << "请输入电话" << endl;
		string phone; cin >> phone;
		abs->arr[abs->size].phone = phone;

		cout << "请输入家庭住址" << endl;
		string address; cin >> address;
		abs->arr[abs->size].addr = address;

		abs->size += 1;
		cout << "您已经添加成功！" << endl;
		system("pause");
	}
	else
	{
		cout << "通讯录已经满了，添加失败" << endl;
		return;
	}

}

3.显示联系人

//显示联系人
void showperson(books* abs)
{
	if (abs->size == 0)
		cout << "当前记录为空" << endl;
	else
	{
		for (int i = 0; i < abs->size; i++)
		{

			cout << "姓名是：" << abs->arr[i].name << endl;
			cout << "性别是：" << (abs->arr[i].sex==1 ? "男":"女") << endl;
			cout << "年龄是：" << abs->arr[i].age << endl;
			cout << "电话是：" << abs->arr[i].phone << endl;
			cout << "住址是：" << abs->arr[i].addr << endl;
		}
	}
	system("pause");

}

4.判断联系人是否存在

int exist(books* abs, string name)
{
	for (int i = 0; i < abs->size; i++)
	{
		if (abs->arr[i].name == name)
			return i;
	}
	return -1;
}

5.删除联系人

void deletee(books* abs,string name)
{
	int ret = exist(abs, name);
	for (int i = ret; i < abs->size; i++)
	{
		abs->arr[i] = abs->arr[i + 1];
	}
	abs->size--;
	cout << "删除成功" << endl;
}

6.查找联系人

其中 system("cls"); 表示清空之前输出的所有数据

void find(books* abs, string name)
{
	int ret = exist(abs, name);
	if (ret == -1)
	{
		cout << "查无此人" << endl;
		return;
	}
	else
	{
		cout << "姓名是：" << abs->arr[ret].name << endl;
		cout << "性别是：" << (abs->arr[ret].sex == 1 ? "男" : "女") << endl;
		cout << "年龄是：" << abs->arr[ret].age << endl;
		cout << "电话是：" << abs->arr[ret].phone << endl;
		cout << "住址是：" << abs->arr[ret].addr << endl;
	}
	system("cls");
}

7.修改联系人

void modify(books* abs, string name)
{
	int ret = exist(abs, name);
	if (ret == -1)
	{
		cout << "查无此人" << endl;
		return;
	}
	else   //只做名字的修改
	{
		string name; cout << "请重新输入要修改成的姓名" << endl;
		cin >> name;
		abs->arr[ret].name = name;
		cout << "修改成功！";
	}
}

8.删除通讯录

我们不一定要一个个删除数据，我们只需要将记录中的联系人个数等于0即可

void clean(books* abs)
{
	abs->size = 0;  //将当前记录的联系人记录为0
	cout << "通讯录清空成功" << endl;
	system("pause");
}

完整代码如下

#include <iostream>
#include <string>
#define max 100
using namespace std;
//设计联系人结构体
struct person
{
	string name;
	int sex=0;  //男1 女2
	int age=0;
	string phone;
	string addr;
 };
//通讯录结构体
struct books
{
	struct person arr[max];
	int size=0;  //联系人个数
};
void addperson(books* abs)
{
	if (abs->size <= max)
	{
		string name;
		cout << "请输入姓名： " << endl; cin >> name;
		abs->arr[abs->size].name = name;

		cout << "请输入性别 男1 女2" << endl;
		while (1)
		{
			int sex = 0; cin >> sex;
			if (sex == 0 || sex == 1)
			{
				abs->arr[abs->size].sex = sex;
				break;
			}
			else
				cout << "输入有误，请重新输入" << endl;
		}

		cout << "请输入年龄" << endl;
		int age = 0; cin >> age;
		abs->arr[abs->size].age = age;

		cout << "请输入电话" << endl;
		string phone; cin >> phone;
		abs->arr[abs->size].phone = phone;

		cout << "请输入家庭住址" << endl;
		string address; cin >> address;
		abs->arr[abs->size].addr = address;

		abs->size += 1;
		cout << "您已经添加成功！" << endl;
		system("pause");
	}
	else
	{
		cout << "通讯录已经满了，添加失败" << endl;
		return;
	}

}
//显示联系人
void showperson(books* abs)
{
	if (abs->size == 0)
		cout << "当前记录为空" << endl;
	else
	{
		for (int i = 0; i < abs->size; i++)
		{

			cout << "姓名是：" << abs->arr[i].name << endl;
			cout << "性别是：" << (abs->arr[i].sex==1 ? "男":"女") << endl;
			cout << "年龄是：" << abs->arr[i].age << endl;
			cout << "电话是：" << abs->arr[i].phone << endl;
			cout << "住址是：" << abs->arr[i].addr << endl;
		}
	}
	system("pause");
