Yeah, but as far as I understand that’s not a C vulnerability. It wasn’t added. C just exposes how the underlying CPU works.
If you could avoid exposing dangerous memory quirks but still retain the same power… well, you’d have invented Rust. Rust is a better language than C, I agree with that.
Edit: Yep, just double checked. Buffers live in physical memory and have to be finite, so if you advance outside of them you’ll go somewhere else. Scanf’s not special, this is just another inherent pointer issue.
Okay, but how do you code on a CPU without directly interfacing the CPU at some point? Python and JavaScript both rely on things written in mid-level languages. There’s a difference between a bad tool and one that just has limitations inherent to the technology.
Like, to echo the meme a bit, it’s not a totally straight comparison. They have different roles.
Yes, also Rust. It wasn’t an option until recently though.
The times when C or C++ is worth it definitely isn’t always, but I’m not sure I’d class much of OS programming and all embedded and high-performance computing as small. If you have actual hard data about how big those applications are relative to others, I’d be interested.
Also, it’s a nitpick, but I’d personally say a footgun has to be unforeseeable, like literal shoe guns being added to a video game where guns were previously always visible. Once you understand pointers C is reasonably consistent, just hard and human-error-prone. The quirks follow from the general concepts the language is built on.
I could go on
i will fine you
JavaScript is also not fine.
C++ apparently has a lot of footguns if you use too many parts of it. C and orthodox C++ are fine.
people say this but C is significantly more batshit than javascript
oh you used
scanf? one of the basic functions of our language? sorry that’s got a buffer overflow vulnerability so now your application is compromisedYeah, but as far as I understand that’s not a C vulnerability. It wasn’t added. C just exposes how the underlying CPU works.

exposing the machinations of the underlying CPU with no regard for safety is like, the definition of a footgun

a footgun isn’t inherently bad, it just implies a significant amount of risk
yes, if you need the ability to code on a low level, maybe C is necessary, but the times where that is actually necessary is smol
also rust

What’s the point of having a function in the standard library if the universal recommendation is to never use it?
Is that the recommendation? This is the first time I’ve actually seen it discussed.
I’m wondering at this point if a new, different stdlib would be better. Or just use Rust.
To be honest, my comment probably applies more to
gets, but the point is the same.Go on…
Don’t give them ideas
