C++ 代码格式化

Question

我在你的论坛上读了很多，而且读了很长时间。现在这是我的第一个问题。我在我的 latex 文档中包含了 C++ 代码，并且成功格式化了它。但有一个细节不起作用。我想用括号突出显示包含语句#include<**graphics.h>** 和#包括<**cmath.h>** 预定义颜色 MyMoreK 和带括号的三角函数sin（**角度））** 和cos（**角度)** 使用预定义颜色 MyTrigoFunctions。括号 [graphics.h/cmath.h/angle] 的内容应保留为绿色。我试了几天，但还是无法让它工作。希望你能帮助我！非常感谢你的帮助和建议！

德语中也一样：http://golatex.de/cundund-code-wie-kann-ich-noch-einzelne-worte-hervorheben-t18862.html
