最近被老壁灯盗号了，可能影响了大家，有影响跟我说~~

平常在我们会使用system来调整颜色，可这样实在是太单一了，因为这样只能是统一所有颜色，不能做像想象那样一行一个颜色 于是，我们可以用SetConsoleTextAttribute来进行操作，同时，它需要用到windows.h头文件，具体操作如下： 注意：这是10进制的代码，接下来我会给出一个10进制的颜色大全 有用就点个赞吧(づ￣ 3￣)づ

啊？！ 这啥玩意？！

fabs 浮点数x的绝对值； abs 整数x绝对值； round double型x 四舍五入取整； floor double型x 向下取整； ceil double型x 向上取整； pow doublea,b ,返回a^b; sqrt double型x，求根号x；

1.pow a*b的结果 pow(2,4)=16 2.abs x的绝对值（整数） abs(-3)=3 3.fabs x的绝对值 （浮点数）fabs(-7.54)=7.54 4.round x四舍五入取整的结果 round(2.1)=2.0,round(2.7)=3 5.ceil x向上取整的结果ceil(2.1)=30,ceil(-2.1)=2.0
