缘起：
在玩Codeblocks自带的俄罗斯方块时觉得不错，然而有时间限制。所以想自己再写一个。
程序效果：
主要内容：
程序中有一个board数组，其中有要显示的部分，也有不显示的部分，不显示的部分都存储1。
如下图：
shape采用4*4数组(shape)保存。如：
0 0 0 0
0 1 0 0
1 1 1 0
0 0 0 0
另外用变量row和column保存shape数组左上角在board中的位置。
每次下落或左右移动，先对row和column做出改变，然后检测当前row和column下，shape是否重合了为1的格子，如果有重合，就说明shape出界了或者到达下落最低点，则要恢复row和column值。另外，如果是下落，还要将shape放在board上，并产生新的shape。
旋转时，先对shape数组进行旋转操作，然后检测重合，如果有重合，则反向旋转回来。
