一个字符界面的俄罗斯方块

刚刚进入软件开发行业的时候加了不少QQ技术群，其实群里面好多都是扯淡的，而且里面的人水平不一，多么简单的问题都问得出来，还有想拜师啊之类的，后来就都退了。但是其中一个群里面有一个公告是让大家写一个字符界面的俄罗斯方块，感觉很好玩儿，就试着写了一个，玩儿自己写的“游戏”感觉还是挺爽的，虽然很简陋，但是刚刚开始嘛，还是很有成就感的。

开始想了很多办法，不知道怎么来定义数据结构，还有里面的好多变换，新手是痛苦的，平时看起来那么简单的东西做起来原来那么难。但是最后还是笨人有笨法，当时的我多么佩服自己这个想法。整个的界面很简单也很简陋，不过还是有些可玩儿性的。基本就是模仿原来玩儿过的图形界面的俄罗斯方块做的，分成10个速度级别啊，一次消几行得分加倍啊，分数越高速度越快啊等等，也就这些了。最后还找了一个比较方形的字符来表示方块，一个笑脸哦，咔咔，效果还是不错嘀

整个工程很简单，一共就两个文件，这个是头文件Tetris2.h
