用c++生成一段餐厅点餐系统的代码能够实现基本点餐功能和餐厅管理功能

好的，以下是一个简单的餐厅点餐系统的 C++ 代码，包含基本点餐功能和餐厅管理功能。注意，这只是一个示例代码，可以根据具体需求进行修改和完善。

#include <iostream>
#include <string>
#include <vector>
using namespace std;

public:
    string name;
    float price;
    Dish(string name, float price) : name(name), price(price) {}

    vector<Order> orders;
    Table(int id) : id(id) {}

        dishes.push_back(Dish(name, price));
    }

    void addTable(int id) {
        tables.push_back(Table(id));
    }

    void printDishes() {
        cout << "Dishes:\n";

        Dish* dish = findDish(dishName);

                    table->orders.erase(table->orders.begin() + i);
                    cout << "Order removed successfully\n";
                    return;
                } else {
                    cout << "Not enough orders to remove\n";
                    return;

    }

private:

    Dish* findDish(string name) {

            }
        }
        return nullptr;

};

int main() {
    Restaurant restaurant;
    restaurant.addDish("Hamburger", 4.99);
    restaurant.addDish("French fries", 1.99);
    restaurant.addDish("Coke", 0.99);

    restaurant.addTable(1);
    restaurant.addTable(2);

    restaurant.printDishes();

    restaurant.takeOrder(1, "Hamburger", 2);
    restaurant.takeOrder(1, "French fries", 1);
    restaurant.takeOrder(2, "Coke", 3);

    restaurant.printTables();

    restaurant.removeOrder(1, "Hamburger", 1);

    restaurant.printTables();

    return 0;
}

以上代码实现了一个简单的餐厅点餐系统，包含了添加菜品和桌子、打印菜单和桌子信息、点餐和取消点餐等功能。可以根据需要进行修改和完善。
