C++设计模式：模板模式

一、源代码：

#include<iostream>
#include<memory>

using namespace std;

class Game
{
public:
    virtual void initialize() = 0;
    virtual void startPlay() = 0;
    virtual void endPlay() = 0;
    virtual ~Game() = default;

    void play()
    {
        initialize();
        startPlay();
        endPlay();
    }
};

class Cricket:public Game
{
public:
    virtual void initialize() override
    {
        cout<<"Cricket Game Initialized! Start playing."<<endl;
    }
    virtual void startPlay() override
    {
        cout<<"Cricket Game Started.Enjoy the game!"<<endl;
    }
    virtual void endPlay() override
    {
        cout<<"Cricket Game Finished!"<<endl;
    }
};

class Football:public Game
{
public:
    virtual void initialize() override
    {
        cout<<"Football Game Initialized! Start playing."<<endl;
    }
    virtual void startPlay() override
    {
        cout<<"Football Game Started.Enjoy the game!"<<endl;
    }
    virtual void endPlay() override
    {
        cout<<"Football Game Finished!"<<endl;
    }
};

int main()
{
    shared_ptr<Game> game = make_shared<Cricket>();
    game->play();
    cout<<endl;
    game = make_shared<Football>();
    game->play();
}

二、运行结果：
