写一个充分利用c++面向对象思想的酒水管理系统

好的，我可以给你写一个更充分利用C++面向对象思想的酒水管理系统，以下是代码实现：

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

using namespace std;

// 酒水类
class Drink {
public:
    Drink(string name, int price, int count) : name(name), price(price), count(count) {}
    string getName() const {
        return name;
    }
    int getPrice() const {
        return price;
    }
    int getCount() const {
        return count;
    }
    void addCount(int num) {
        count += num;
    }
    virtual void showInfo() const {
        cout << "名称：" << name << "，价格：" << price << "元，库存：" << count << "瓶" << endl;
    }
    virtual int getDiscount() const {
        return 100;
    }
protected:
    string name; // 名称
    int price; // 价格
    int count; // 数量
};

// 啤酒类
class Beer : public Drink {
public:
    Beer(string name, int price, int count, bool isImported) : Drink(name, price, count), isImported(isImported) {}
    void showInfo() const override {
        cout << "啤酒：" << name << "，价格：" << price << "元，库存：" << count << "瓶，";
        if (isImported) {
            cout << "进口";
        } else {
            cout << "国产";
        }
        cout << endl;
    }
    int getDiscount() const override {
        if (isImported) {
            return 90;
        } else {
            return 95;
        }
    }
private:
    bool isImported; // 是否进口
};

// 红酒类
class Wine : public Drink {
public:
    Wine(string name, int price, int count, int age) : Drink(name, price, count), age(age) {}
    void showInfo() const override {
        cout << "红酒：" << name << "，价格：" << price << "元，库存：" << count << "瓶，年份：" << age << "年" << endl;
    }
    int getDiscount() const override {
        if (age >= 5) {
            return 85;
        } else {
            return 90;
        }
    }
private:
    int age; // 年份
};

// 酒水管理类
class DrinkManager {
public:
    // 添加酒水
    void addDrink(Drink* drink) {
        drinks.push_back(drink);
    }
    // 根据名称查找酒水
    Drink* findDrink(string name) {
        for (auto& drink : drinks) {
            if (drink->getName() == name) {
                return drink;
            }
        }
        return nullptr;
    }
    // 显示所有酒水
    void showDrinks() const {
        cout << "酒水列表：" << endl;
        for (auto& drink : drinks) {
            drink->showInfo();
        }
    }
    // 购买酒水
    bool buyDrink(string name, int num) {
        Drink* drink = findDrink(name);
        if (drink == nullptr) {
            cout << "找不到该酒水" << endl;
            return false;
        } else if (drink->getCount() < num) {
            cout << "库存不足" << endl;
            return false;
        } else {
            int price = drink->getPrice() * num * drink->getDiscount() / 100;
            drink->addCount(-num);
            cout << "购买成功，共支付：" << price << "元" << endl;
            return true;
        }
    }
private:
    vector<Drink*> drinks; // 酒水列表
};

int main() {
    DrinkManager manager;

    Drink* beer1 = new Beer("百威", 5, 10, false);
    Drink* beer2 = new Beer("青岛", 4, 20, true);
    Drink* wine1 = new Wine("拉菲", 100, 5, 5);
    Drink* wine2 = new Wine("窖藏", 50, 10, 2);

    manager.addDrink(beer1);
    manager.addDrink(beer2);
    manager.addDrink(wine1);
    manager.addDrink(wine2);

    while (true) {
        cout << "请选择：1.查看酒水 2.购买酒水 3.退出" << endl;
        int choice;
        cin >> choice;
        if (choice == 1) {
            manager.showDrinks();
        } else if (choice == 2) {
            cout << "请输入酒水名称和购买数量：" << endl;
            string name;
            int num;
            cin >> name >> num;
            manager.buyDrink(name, num);
        } else if (choice == 3) {
            break;
        } else {
            cout << "输入有误，请重新选择" << endl;
        }
    }

    delete beer1;
    delete beer2;
    delete wine1;
    delete wine2;

    return 0;
}

这个酒水管理系统充分利用了C++面向对象思想，使用了继承和多态等特性。它支持添加啤酒和红酒两种类型的酒水，并且可以根据不同的酒水类型显示不同的信息和折扣率。在购买酒水时，会根据酒水的信息计算出实际需要支付的金额。

希望这个更加优化的酒水管理系统能够满足你的需求，如果有任何问题或者需要改进的地方，欢迎指出。
