你如何理解大块代码？ [英] How do you understand a large chunk of code?

问题描述

我是一个刚刚开始工作的新生大学毕业生。在我的加速期，我需要学习很多产品代码。有一些设计文档，但他们没有帮助太多。

I am a fresh college grad student that just started my job. In my ramp up period, I need to learn a lot of product code. There are some design docs but they do not help much.

您可以提供一些一般技术来浏览和了解大量产品代码（特别是C ++）吗？

Can you provide some general techniques to browse and understand huge product code (specifically C++)?

推荐答案

通过 doxygen 运行。这将生成html文档，这将有助于即使代码没有正确的doxygen风格的注释。

Run it through doxygen. This will generate html documentation which will be helpful even if the code does not have proper doxygen-style comments.

另一个很好的建议是通过单元测试，如果有是任何。如果没有单元测试，理解代码的好方法是编写自己的单元测试。这样做的努力将付出很多代价。

Another good advice is to look through the unit tests, if there are any. If there are no unit tests, a good way to understand the code is to write your own unit tests. The effort to do this will pay for itself many times over.
