制作俄罗斯方块小游戏（一）

分析：

printf函数高级用法

'\033['：表示转义序列的开始

'm'：表示转义序列的结束

'0'：重置所有属性

'1'：设置粗体或高亮

'30-37'：设置字体色 30: 黑 31: 红 32: 绿 33: 黄 34: 蓝 35: 紫 36: 深绿 37: 白色

'40-47'：设置背景色 40: 黑 41: 红 42: 绿 43: 黄 44: 蓝 45: 紫 46: 深绿 47: 白色

/033[0m 关闭所有属性

/033[1m 设置高亮度

/033[4m 下划线

/033[5m 闪烁

/033[7m 反显

/033[8m 消隐

/033[30m -- /033[37m 设置前景色

/033[40m -- /033[47m 设置背景色

/033[nA 光标上移n行

/033[nB 光标下移n行

/033[nC 光标右移n行

/033[nD 光标左移n行

/033[y;xH设置光标位置

/033[2J 清屏

/033[K 清除从光标到行尾的内容

/033[s 保存光标位置

/033[u 恢复光标位置

/033[?25l 隐藏光标

/033[?25h 显示光标
