生成订餐管理系统的C加加代码

好的，根据之前的订餐管理系统设计，下面是一个简单的C++代码示例：

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

using namespace std;

// 定义餐厅信息结构体
struct Restaurant {
    string name;
    string address;
    string phone;
};

// 定义菜品信息结构体
struct Dish {
    string name;
    float price;
    string description;
    Restaurant* restaurant;
};

// 定义订单信息结构体
struct Order {
    int id;
    vector<Dish*> dishes;
    float total;
    Restaurant* restaurant;
};

// 定义餐厅管理员类
class RestaurantAdmin {
public:
    RestaurantAdmin(string name, string password, Restaurant* restaurant) {
        this->name = name;
        this->password = password;
        this->restaurant = restaurant;
    }

    void addDish(Dish* dish) {
        restaurant->dishes.push_back(dish);
    }

    void removeDish(Dish* dish) {
        for (int i = 0; i < restaurant->dishes.size(); i++) {
            if (restaurant->dishes[i] == dish) {
                restaurant->dishes.erase(restaurant->dishes.begin() + i);
                break;
            }
        }
    }

private:
    string name;
    string password;
    Restaurant* restaurant;
};

// 定义顾客类
class Customer {
public:
    Customer(string name, string phone) {
        this->name = name;
        this->phone = phone;
    }

    void placeOrder(Order* order) {
        orders.push_back(order);
    }

private:
    string name;
    string phone;
    vector<Order*> orders;
};

int main() {
    // 创建餐厅管理员和顾客
    Restaurant* restaurant = new Restaurant{"Restaurant A", "123 Main St", "555-1234"};
    RestaurantAdmin* admin = new RestaurantAdmin{"Admin A", "password", restaurant};
    Customer* customer = new Customer{"Customer A", "555-5678"};

    // 创建菜品
    Dish* dish1 = new Dish{"Dish 1", 10.99, "This is dish 1", restaurant};
    Dish* dish2 = new Dish{"Dish 2", 8.99, "This is dish 2", restaurant};

    // 餐厅管理员添加菜品
    admin->addDish(dish1);
    admin->addDish(dish2);

    // 创建订单
    Order* order = new Order{1, {dish1, dish2}, 19.98, restaurant};

    // 顾客下单
    customer->placeOrder(order);

    return 0;
}

以上代码包含了餐厅信息、菜品信息、订单信息等实体的定义，以及餐厅管理员、顾客的类定义。在main函数中，我们创建了餐厅管理员、顾客、菜品、订单等对象，并进行了一些简单的操作，例如添加菜品、下订单等。当然，这只是一个简单的示例，实际的订餐管理系统可能会更加复杂。在实现订餐管理系统时，你需要根据具体的需求进行设计和开发。
