希望通过本课程设计中简单系统的开发，使学生掌握软件设计的基本方法和基本流程，提高自己的综合应用能力。

二、设计要求利用C++编写俄罗斯方块游戏，使俄罗斯游戏能够在Microsoft Visual C++6.0上运行该游戏。

二、设计内容：俄罗斯方块（1）游戏等级：游戏分为难中易三个等级，等级越高，方块下落速度越快；（2）由方向键控制游戏：上键控制方块变形、下键控制方块下移并判断是否有消行、左键控制方块左移、右键控制方块右移；（3）游戏积分：一次性消的行数越多加的分数越多，当达到一定分数自动提高一个游戏等级。

三、系统分析与设计1.程序功能模块：2.程序流程图：第二部分数据结构设计1.游戏需求随机给出不同的形状（长条形、Z字形、反Z形、田字形、7字形、反7形、T字型）下落填充给定的区域，若填满一条便消掉，记分，当达到一定的分数时，过关，每关方块下落的速度不同，若在游戏中各形状填满了给定区域，为输者。

2.游戏界面需求:良好的用户界面，以键盘操作，有关数显示和分数显示。

让方块在一定的区域内运动和变形,并且显示下一个即将出现的方块。

3.游戏形状(方块)需求:良好的方块形状设计，绘制七种常见的基本图形（长条形、Z字形、反Z形、田字形、7字形、反7形、T字型），各个方块要能实现它的变形，可设为顺时针或逆时针变形，一般为逆时针。
