本代码运行环境是Windows下的VS2013
首先创建tetris.cpp
然后依次创建view.h以及view.cpp、model.h以及model.cpp。

代码如下：

view.h

#pragma once


#include 
void ShowBackground();
void ShowBrick();
void ShowGame();
void OnLeft();
void OnRight();
void OnUp();
void OnDown();

view.cpp

 }
}

void OnRight()
{

 {

 ShowGame();
 }
}

{

 {

 }
}

void OnDown()
{

 {

 ShowGame();
 }
 else
 {
 //固定方块至背景，并且产生新方块
 CombineBgBrick();

 //判断游戏是否结束，并给出对应提示
 }
}
