once you understand C++ the pitfalls of C++ are reasonably consistent
there are like what, 3 operating systems these days?
assume those are all written entirely in c and combine them and compare that to all code ever written
All of C++? That's unreasonable, it's even in the name that it's very expansive. Yes, if you already know a thing, you won't be surprised by it, that's a tautology.
C is more than just pointers, obviously, but the vast majority of the difficulty there is pointers.
Plus all previous operating systems, all supercomputer climate, physics and other science simulations, all the toaster and car and so on chips using bespoke operating systems because Linux won't fit, every computer solving practical engineering or logistics problems numerically, renderers...
Basically, if your computational resources don't vastly exceed the task to be done, C, Rust and friends are a good choice. If they do use whatever is easy to not fuck up, so maybe Python or Haskell.
similarly, "all of pointers" is unreasonable
"all of pointers" can have a lot of unexpected results
that's literally why java exists as a language, and is so popular
sure, and the quantity of code where true low-level access is actually required is still absolutely minuscule compared to that where it isn't
How? They go where they point, or to NULL, and can be moved by arithmetic. If you move them where they shouldn't go, bad things happen. If you deference NULL, bad things happen. That's it.
If you need to address physical memory or something, that's a small subset of this for sure. It also just lacks the overhead other languages introduce, though. Climate simulations could be in Java or Haskell, but usually aren't AFIAK.
what part of that is explicit to how
scanfworks?I suppose if you treat scanf as a blackbox, then yeah, that would be confusing. If you know that it's copying information into the buffer you gave it, obviously you cant fit more data into it than it's sized for, and so the pointer must be wandering out of range.
Maybe C would be better without stdlib, in that sense. Like, obviously it would be harder to use, but you couldn't possibly be surprised by a library function's lack of safeness if there were none.
yeah i mean if you grok the underlying workings of
scanfthen there's no problemi'd just argue that the problem is understanding what you need to understand is the problem with straight c, and with any language like c++ where you're liable to shoot thineself in thy foot
I'm wondering now how much you could add without introducing any footguns. I'd guess quite a bit, but I can't really prove it. Smart pointers, at least, seem like the kind of thing that inevitably will have a catch, but you could read in and process text from a file more safely than that, just by implementing some kind of error handling.
