推荐答案

你需要的是什么的软件工具静态代码分析使用源代码C：

http：// en。 wikipedia.org/wiki/Static_code_analysis [ ^ ]。



您可以查看以下列表： http://en.wikipedia.org/wiki/List_of_tools_for_static_code_analysis#C.2FC.2B.2B [ ^ ]。



您可以熟悉这些工具中的一些或每个选择适合你的东西;其中一些是开源的。



由于严格的架构，我希望你只拥有不需要太多此类分析的项目和整洁的实施。特别是，全局变量通常是一件坏事，是代码和项目设计不良的标志。很有可能避免它们或至少最小化。

What you need would be the software tool for static code analysis working with the source C code:
http://en.wikipedia.org/wiki/Static_code_analysis[^].

You can review this list: http://en.wikipedia.org/wiki/List_of_tools_for_static_code_analysis#C.2FC.2B.2B[^].

You can get familiar with some or each of those tools and choose what could work for you; some of them are open-source.

And I would wish you to "have" only the projects which don't require much of such analysis, due to strict architecture and neat implementation. In particular, global variables is generally a bad thing, a sign of bad code and project design. It's quite possible to avoid them or at least minimize.
