行为型-模板方法模式

//模板方法模式

#include <iostream>
using namespace std;

//
class DrinkTemplate{
public:
    virtual void BoildWater() = 0; //煮水
    virtual void Brew() = 0; //冲泡
    virtual void PourInCup() = 0; //倒入杯中
    virtual void AddSomething() = 0; //加辅助料

    //模板方法
    void Make(){
        BoildWater();
        Brew();
        PourInCup();
        AddSomething();
    }
};

//冲泡咖啡

    virtual void BoildWater(){
        cout << "煮山泉水..." << endl;
    }

    }
