Its well deserved reputation of being an ultra secure operating system is the byproduct of a no compromise attitude valuing simplicity, correctness, and most importantly proactivity. OpenBSD also deletes code, a lot of code.

such as OpenBSD.
OpenBSD is a fork of NetBSD, another project considered to have above average quality source code. Enough so that Spinellis based his book about code reading on the NetBSD source code.
OpenBSD is one such project.
Also, being able to read and understand code is an important skill in itself.
One of problem of static source code analyzers are false positive. Soon or later you will have to reading code and understand the context. I assume it's better way to improve your C knowledge because you REALLY must understand the code . And besides that the positive effect are more valuable.
