If there’s one thing C is known and (in)famous for, it’s the ease of shooting yourself in the foot with it. And there’s indeed no denying that the freedom C offers comes with the price of making it our own responsibility to tame and keep the language under control. On the bright side, since the language’s flaws are so well known, we have a wide selection of tools available that help us to eliminate the most common problems and blunders that could come back to bite us further down the road. The catch is, we have to really want it ourselves, and actively listen to what the tools have to say.
We often look at this from a security point of view and focus on exploitable vulnerabilities, which you may not see as valid threat or something you need to worry about in your project. And you are probably right with that, not every flaw in your code will lead to attackers taking over your network or burning down your house, the far more likely consequences are a lot more mundane and boring. But that doesn’t mean you shouldn’t care about them.
Buggy, unreliable software is the number one cause for violence against computers, and whether you like it or not, people will judge you by your code quality. Just because Linus Torvalds wants to get off Santa’s naughty list, doesn’t mean the technical field will suddenly become less critical or loses its hostility, and in a time where it’s never been easier to share your work with the world, reliable, high quality code will prevail and make you stand out from the masses.
