请用C++编写下面这个程序设计完成对美发店的简单管理。 功能需求： (1) 定义顾客类，属性有：会员卡号、姓名、性别、电话等信息和相关的对属性做操作的行为。 (2) 定义员工类：属性有：编号、姓名、性别、电话、美发项目（理发、烫发、洗发）等信息和相关的对属性做操作的行为。 (3) 定义美发类：属性有各种美发项目的收费标准和相关的对属性做操作的行为。 (4) 定义一个管理类。 (5) 添加、删除、修改、查询顾客信息和雇员信息，要求编号要唯一，如果添加了重复编号的记录时，则提示数据添加重复并取消添加；删除、修改、查询时，如果没有对应人员记录，则提示“记录为空！”并返回操作。

好的，以下是一个简单的美发店管理系统的C++代码实现：

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>

using namespace std;

// 定义顾客类
class Customer {
public:
    Customer(string cardId, string name, char sex, string phone)
        : m_cardId(cardId), m_name(name), m_sex(sex), m_phone(phone) {}

    // 获取和设置会员卡号
    string getCardId() { return m_cardId; }
    void setCardId(string cardId) { m_cardId = cardId; }

    // 获取和设置姓名
    string getName() { return m_name; }
    void setName(string name) { m_name = name; }

    // 获取和设置性别
    char getSex() { return m_sex; }
    void setSex(char sex) { m_sex = sex; }

    // 获取和设置电话
    string getPhone() { return m_phone; }
    void setPhone(string phone) { m_phone = phone; }

private:
    string m_cardId;
    string m_name;
    char m_sex;
    string m_phone;
};

// 定义员工类
class Employee {
public:
    Employee(int number, string name, char sex, string phone, string project)
        : m_number(number), m_name(name), m_sex(sex), m_phone(phone), m_project(project) {}

    // 获取和设置编号
    int getNumber() { return m_number; }
    void setNumber(int number) { m_number = number; }

    // 获取和设置姓名
    string getName() { return m_name; }
    void setName(string name) { m_name = name; }

    // 获取和设置性别
    char getSex() { return m_sex; }
    void setSex(char sex) { m_sex = sex; }

    // 获取和设置电话
    string getPhone() { return m_phone; }
    void setPhone(string phone) { m_phone = phone; }

    // 获取和设置美发项目
    string getProject() { return m_project; }
    void setProject(string project) { m_project = project; }

private:
    int m_number;
    string m_name;
    char m_sex;
    string m_phone;
    string m_project;
};

// 定义美发类
class Hairdressing {
public:

        m_price["haircut"] = 50;
        m_price["perm"] = 100;
        m_price["wash"] = 20;
    }

    // 获取美发项目的收费标准
    int getPrice(string project) {
        return m_price[project];
    }

private:
    // 美发项目的收费标准
    map<string, int> m_price;
};

// 定义管理类
class Management {
public:
    // 添加顾客信息
    void addCustomer(Customer& customer) {
        // 检查会员卡号是否唯一
        for (auto& c : m_customers) {
            if (c.getCardId() == customer.getCardId()) {
                cout << "添加失败，会员卡号重复！" << endl;
                return;
            }
        }

        m_customers.push_back(customer);
        cout << "添加成功！" << endl;
    }

    // 删除顾客信息
    void removeCustomer(string cardId) {
        auto it = find_if(m_customers.begin(), m_customers.end(), [cardId](Customer& c) { return c.getCardId() == cardId; });
        if (it == m_customers.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        m_customers.erase(it);
        cout << "删除成功！" << endl;
    }

    // 修改顾客信息
    void updateCustomer(Customer& customer) {
        auto it = find_if(m_customers.begin(), m_customers.end(), [cardId = customer.getCardId()](Customer& c) { return c.getCardId() == cardId; });
        if (it == m_customers.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        *it = customer;
        cout << "修改成功！" << endl;

    // 查询顾客信息
    void queryCustomer(string cardId) {
        auto it = find_if(m_customers.begin(), m_customers.end(), [cardId](Customer& c) { return c.getCardId() == cardId; });
        if (it == m_customers.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        cout << "会员卡号：" << it->getCardId() << endl;
        cout << "姓名：" << it->getName() << endl;
        cout << "性别：" << it->getSex() << endl;
        cout << "电话：" << it->getPhone() << endl;
    }

    // 添加员工信息
    void addEmployee(Employee& employee) {
        // 检查编号是否唯一
        for (auto& e : m_employees) {
            if (e.getNumber() == employee.getNumber()) {
                cout << "添加失败，编号重复！" << endl;
                return;
            }
        }

        m_employees.push_back(employee);
        cout << "添加成功！" << endl;
    }

    // 删除员工信息
    void removeEmployee(int number) {
        auto it = find_if(m_employees.begin(), m_employees.end(), [number](Employee& e) { return e.getNumber() == number; });
        if (it == m_employees.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        m_employees.erase(it);
        cout << "删除成功！" << endl;
    }

    // 修改员工信息
    void updateEmployee(Employee& employee) {
        auto it = find_if(m_employees.begin(), m_employees.end(), [number = employee.getNumber()](Employee& e) { return e.getNumber() == number; });
        if (it == m_employees.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        *it = employee;
        cout << "修改成功！" << endl;
    }

    // 查询员工信息
    void queryEmployee(int number) {
        auto it = find_if(m_employees.begin(), m_employees.end(), [number](Employee& e) { return e.getNumber() == number; });
        if (it == m_employees.end()) {
            cout << "记录为空！" << endl;
            return;
        }

        cout << "编号：" << it->getNumber() << endl;
        cout << "姓名：" << it->getName() << endl;
        cout << "性别：" << it->getSex() << endl;
        cout << "电话：" << it->getPhone() << endl;
        cout << "美发项目：" << it->getProject() << endl;
    }

private:
    vector<Customer> m_customers; // 顾客列表
    vector<Employee> m_employees; // 员工列表
};

int main() {
    // 创建一个美发店管理对象
    Management management;

    // 添加顾客信息
    Customer customer1("001", "Tom", 'M', "13800000001");
    management.addCustomer(customer1);

    // 添加员工信息
    Employee employee1(1001, "Lucy", 'F', "13800000002", "haircut");
    management.addEmployee(employee1);

    // 查询顾客信息
    management.queryCustomer("001");

    // 查询员工信息
    management.queryEmployee(1001);

    // 修改顾客信息
    Customer customer2("001", "Tony", 'M', "13800000003");
    management.updateCustomer(customer2);

    // 修改员工信息
    Employee employee2(1001, "Lily", 'F', "13800000004", "perm");
    management.updateEmployee(employee2);

    // 删除顾客信息
    management.removeCustomer("001");

    // 删除员工信息
    management.removeEmployee(1001);

    return 0;
}

以上代码实现了添加、删除、修改、查询顾客信息和员工信息的功能，并且实现了编号和会员卡号的唯一性检查。当添加重复记录时，会提示“添加失败，编号或者会员卡号重复！”；当删除、修改、查询不存在的记录时，会提示“记录为空！”
