I copy stack exchange and tutorial code for my C projects. If they have a star thingy then I keep it there

>>10776102

I'm an ME and all I know is boomer tier C, what should I learn if i want to go into software?

>>10776171
Learn bits and pieces of every important language, enough to put each one your resume. You don't need to be an expert in anything

>>10776102
They learning it because teachers teaching it. It's an evil circle.

>>10776102
C is the foundation of many programming languages. If you know C, you already know bits and pieces of other languages.

There's a prof in my uni that STILL teaches Fortran.

>>10776171
python

At least for science, for a while there C was sort of important because if you were just writing numerical programs, you wanted it to be as fast as possible.

Nowadays, with desktop computers orders of magnitude faster than the fastest computers of yore, you can just use Python.

For non-scientific applications, C is mostly used for operating system code. Most other applications are now written in either C++ or Java.

>>10776234
Many freshmen in my country learn Fortran in their own time as that was everything they knew in HS. I want to leave.

>>10776337
If you are going to any sort of numerical analysis field, it's a must to learn C. No one publishing serious work will present their programs in python.

>>10776364
>Publishing on source code
No one does this, numerical analysis is not code monkeying

>>10776102

I can't believe Python made it from "meme tier kiddie language with no strong typing" to the favored language lol

>>10776399
You don’t know what strong typing is either.

>>10776102
Learning even a beginner level amount of C gives you a deeper insight into what programming actually does.

>>10776102
C is an incredible language for embedded systems and operating systems, and is still extremely prevalent in those fields. For any other application I would agree, there are better languages for the job.

>>10776102
They don't. They learn C++20

>>10776337
I think C++ is preferred for new scientific work also. Operator overloading is just too useful for defining new data types and using them in a familiar way. TMP can also be used for compile time units checking in physics applications, if you don't mind the compile times.

>>10777175
I'm pretty sure python is taking over the sciences, modern biology and astro ml is all python, data analysis at cern is python, I can't imagine any top tier University teaching science grad students C++ lmao. Obviously any C based language is going to be more efficient but that doesn't really matter with cython and cloud computing. People without a programming background now can write code to perform complex tasks and leverage their scientific knowledge without needing cs/stat specialists, so Python is more prevalent in the sciences than any other sector.

It's useful in applied cryptography.

>>10778661
people without a programming background tend to write bad code because they have opinions about the miracles of cloud computing like yours

>>10776234
>>10776358
You know, once the "old guard" will be completely out, we'll need people to maintain these systems based on Fortran/Cobol. This might be extremely useful in the long run.

I mostly chad, except I do know what pointer is and I can't find high paying data related job. So I'm chad virgin.

Why the fuck do I find it so hard to read Python?

>>10776102
Sometimes it's nice to be able to tell the computer what you want it to do without 8 levels of abstraction

>>10778680
Yes, and people with a programming background who are gainfully employed tend to prefer languages that let them get things done as quickly and easily as possible. Hence why everyone is using modern high-level languages and C is mostly the domain of neckbearded hobbyists and students with self-esteem issues.

Python doesn’t have the language features necessary for writing highly efficient algorithms natively. I’m talking about cache aware algorithms, arena allocators, intrusive containers, etc. Cython isn’t comparable to C++ feature wise in these regards.
The Python is mostly a user friendly wrapper for C/C++/Fortran libraries. So it works as long as you stay within the domain of numpy and friends. In this regard Julia is actually a viable alternative for when there isn’t a Python library and you need performance. I know some physicists use to avoid writing anymore Fortran.

>>10776102
C is used in a lot of discrete electronics.

>>10776337
Your high performance numerical and machine learning python libraries are just C, C++ and Fortran under the hood.
Most scientific python code is just a thin wrapper over a bunch of calls to other languages. And, for that, whatever performance python has mostly irrelevant.

>Why do people even learn C in 2019?
It's the purest and most direct / least obfuscated language there is without dropping down to 1:1 mapped assembly.
It only seems strange or unnecessarily complicated because you're working with a lie built on top of a giant pile of horribly tortured hidden processes that do all the real work for you.

>>10783320
is the pointer syntax in that image retarded or have i been doing it wrong the whole time

>>10783373
It’s wrong.

>>10783373
No, you either pass the pointer itself or $reference the value.

Technically if you're going through a pointer to a list of pointers, and use a pointer-to-pointer, then function_needs_pointer(*ptr) would be valid

There's no meaning to * after a single value. It's an error.

I write bad code, but you write no maths. If it's for science it's just a tool to help with doing science. Who cares if it's inefficient as long as it works

Genuine question, is R a meme? I've seen it being tossed around as an alternative to Python.

>>10776337
>you can just use python
This is not entirely true. People are using Python over C because of Cython which allows you to have comparable performance of C but with the benefit of all the abstractions of Python, but even then people still use a layer of C for the more performance critical tasks in a lot of ML and Ai research.

>>10784103
Learn lua.

Because the microcontroller platform that the company I work for invested in and negotiated long term contracts for yearly volumes at minimum prices only supports C. And the largest version I can use just has 256 kB of ROM and 16 kB RAM. So space is at a premium.

Can't wait for C babies to learn what a compiler is and what it does.
Also, C pointers are not hardware pointers, they are abstracted. You aren't working as close to the metal as you think you are
>>10780860
This.

Also pic says:

Not:

You sound like you just wanted to pick a fight. C is definitely as low level as it gets barring assembly where it's not really even a language anymore so much as a one to one mapping of the machine.

the python interpreter is written in C you fucking idiot. so is every other piece of software between your python code and the hardware.

i really hope you're a troll

>>10778995
Python can be hard to read because Python has such loose syntax that you can write atrocious bullshit that should never see the light of day and it will run.
Languages like C have enough mandatory structure to them that it's not so easy to completely mask what the fuck is actually happening.

>>10788787

chad data scientists are treated like rock stars. they're job is just to produce juked data to support whatever conclusions the board has already made.

the trick is to swallow whatever ethics you have and just go with the flow.

>>10788970
The way you paint it, it seems that """Data Science""" is a pretty comfy position in these boomer institutions. I am kind of making the transition to software eng, but I guess dealing with real deadlines and less pay is pretty shitty.
At least, you are providing real value, and at the same time, and the freedom to create actual products means that the income sealing is much higher.

The trade-off is data science is an obvious meme and when it dies you'll be left with a worthless hole in your resume for whatever time you spent working as a data scientist.
t. anon who was reclassified as a data scientist.
Anyone who voluntarily goes after that title is retarded.
>software eng
Just do that. Software engineer is a legitimate and longstanding profession that can't be taken by any random idiot who spent a day doing Python tutorials on the internet and has a firm handshake.
The more you people go after data scientist positions the more of a meme it'll become until the inevitable backlash where everyone wakes up and realizes maybe it was stupid to spend all that money on a bunch of college grads with zero formal domain specific credentials in the vague hope they would magically reach into a grab bag of corporate data and pull out a way to eliminate customer attrition or double sales.
After that point of realization it'll become cliché that "data scientist" is a stupid thing to hire for per a million normie pop sci articles that explain to executives why they shouldn't do that, and your time as a data scientist will look a lot like having "milkman" or "switchboard operator" on your resume.

After reading ADA creator's interview and some of the history on the language, I am not gonna ever touch anything C-derived again. 83-compatible ADA only, until I maybe encounter another language made by humans for humans, not by schizophreniacs for schizophreniacs.

Only chads know how to program in R

>>10789715
Data Science won't die. It will become the new Marketing, which means it will be a meme career for people who couldn't hack it in either Statistics or Software.

R is like Python on steroids. It's mostly used for statistical analysis and modeling, you can handle complex formulas easily. Most graduate statistics programs and quantitative analyst use it over more general languages.

It's niche but it's really good at what it does.
