运用c++面向对象实现俄罗斯方块

以下是使用C++面向对象实现俄罗斯方块的基本步骤：

1.定义方块类：定义一个方块类，包含方块的形状、颜色、位置等属性，以及方块的移动、旋转等方法。

2.定义游戏区域类：定义一个游戏区域类，包含游戏区域的大小、当前方块、下一个方块等属性，以及游戏区域的初始化、更新等方法。

3.定义游戏控制类：定义一个游戏控制类，包含游戏的开始、暂停、结束等方法，以及游戏得分、等级等属性。

4.实现方块类：实现方块类中的方法，包括方块的移动、旋转等操作。

5.实现游戏区域类：实现游戏区域类中的方法，包括游戏区域的初始化、更新等操作。

6.实现游戏控制类：实现游戏控制类中的方法，包括游戏的开始、暂停、结束等操作。

7.编写主函数：在主函数中创建游戏控制类的对象，调用游戏控制类中的方法，开始游戏。

以下是一个简单的C++面向对象实现俄罗斯方块的代码示例：
