You just have to practice writing a hashtable impl from memory as quickly as possible. Just one of many lovely things that go into interview prep. All completely pointless in current year, of course.

>python is a bloatmaxx language.
Python is bloated because C makes every program have a separate Python interpreter. If it was designed like Mezzano, there would be one interpreter/compiler and runtime shared by all the Python programs and they would use less memory than C programs.

These are people complaining about C.
Regardless of the language, do you really want them to write code?

Or just roll your own implementation of a hashmap, it's literally college freshman DSA, and it only takes a couple minutes to write a primitive one.
C is not a meme. Its only real alternatives are C++, which is trash because operator overloading is literally the idiomatic way to read text from stdin, and Rust, which forces you to learn memory safety which is a very advanced CS topic.
> Rust, which forces you to learn memory safety which is a very advanced CS topic
It's a necessary evil, no?
The problem with C is that it doesn't address this, and most system developers end up learning about aliasing problems and ownership the hard way. Sometimes, the hard way is a shitty vulnerability that takes years to be found in the wild and manages to frick all users.
If this was taught in schools from day one I believe most students would learn at least how to be cautious when using C, if they don't care about Rust.
>C++, which is trash because operator overloading is literally the idiomatic way to read text from stdin
This is a lazy meme answer, you can just not do that way. And they added std::print so you don't even need it for printing any more >Rust, which forces you to learn memory safety which is a very advanced CS topic.
You still need to learn it for C only the language isn't of much help
Writing a doubly linked list is very easy in rust, so once again, I really don't get it. You can even do it exactly like you would do in C. Shit, the rust book for babies literally implements one.
Are we just throwing shit at the wall and seeing what sticks here?

C is more popular now than in the past because of IoT. It's used a lot in embedded programming and for writing core libraries that can be run on any device and used from any programming language.
Every microcontroller industry relies on C and C++ to make their shit work. There's no alternative since Rustrannies are focusing only on software that run on PCs. The only real alternatives to write Rust on microcontrollers are cammunity-driven projects which I don't need to explain why are not a viable option in a professional environment.
You say that and yet C++ and C are the most used among compiled languages.

Only a very small part of Java is in C++, just a few bits around interfacing to the OS (on most platforms). The rest is direct native code and has been for ages.
I'm doing robots and computer graphics in C, but realistically C is going to be worse than langs like Odin, Zig and C++ (if you keep templating to a minimum) even for stuff like video games where C is traditionally the best.
Learning C is still based though, and I encourage everyone to do so. Coming from a higher level, it's refreshingly simple, and keeps the complexity in the program rather than in compiler magic.
>and keeps the complexity in the program rather than in compiler magic.
That's the opposite of what it should be. One compiler can compile millions of programs. You should handle the complexity one time where you get it right instead of making everyone do it millions of times. This is what's wrong with software today and why everything is bloated. Everyone has to reinvent wheels and you can't have good optimized implementations of anything.
with equal code quality, a generalized solution is always slower than a situation-tailored one.
thats bc a generalized solution will always have more checks to do than a specialized one.
and no, thats not whats wrong with software today.

Come into embedded development, nobody will ever ask you about implementing hashmaps since RAM here is extremely limited and for safety reason is better to just write everything using a RAII approach.

There's your fricking hash map in C. The hashing function is an identity. If the interviewer doesn't like it, he's a homosexual.
>No collision resolution
There are no collisions because all keys are unique, which I can assume because no one said that memory is limited.
incredibly based.

You never had a chance, homosexual.

I moved from C to Rust, but implementing a hashmap in C isn't a particularly complex or time consuming problem at all. I don't get it.
Unless the question was about hashing algorithms I guess, never looked into those at all.
what jobs are there in C, really? automative and embeded?
how is this

genuinely curious, what business are actually using c to create products these days?
C is more popular now than in the past because of IoT. It's used a lot in embedded programming and for writing core libraries that can be run on any device and used from any programming language.

No-one. It's a dead language now, used only by maintainers.
It's the first thing they teach you in Cs50.
How much production software is created in CS50 courses?
How much is created by neets arguing over languages on IQfy?
I argue about C vs C++ vs Rust vs Zig vs Python vs Ruby vs shell on IQfy while procrastinating from writing critically important PHP shitware

my guess is sub 30 if it laughed

hash = ((hash << 5) + hash) + c; /* hash * 33 + c */

Why can't sepples dipshits understand that everything is just bytes?

cnile brainlet try not to be in the wrong end of the dunning Kruger curve challenge
>dunning Kruger
The irony is that most people that use that term are on the left end of the curve.
C doesnt have strings, this just works for every 0-terminated data sequence, and its trivial to modify it to work on fixed length data
That's clever, this means it should also work for arbitrary structs because they're null terminated too and there's never a zero in the middle of a
>what does sizeof do
git gud
More importantly, this would require you to properly initialize the padding bytes in all your structs, and I've never seen anyone actually do that.
