Depends on the task. C is usually the fastest and best performing, while java, python and ruby are slower.

>>57070897
no, you cannot objectively rate something like complexity. As for performance well...very prone to nitpicking and comparing apples and oranges, but it can be done.

The most complex: C++
The most simple: Forth
The fastestest: C
The slowest: ... I've heard MATLAB is slow af but it's special-purpose

>>57071948
Has C catched up with fortran in speed?

>>57072566

I guess you never make mistakes when you are using a second language, do you?

>>57070897
Used Fortran at uni for physics. That's about the only application it has though. It's horrid.

What if it were layers of abstraction?

what constitutes 1 layer of abstraction?
you can't answer this objectively, at the end of the day it's up to your judgement.

In terms of performance, Assembly is the best but C(++) is really close second. Generally low-level programming languages have better performance than high-level since they give you more control. It does have the unfortunate side effect of being able to produce code with worse performance if you don't know what you're doing.

What makes you to do so?

>>57072566
You're joking, right? C was always the fastest after assembler.

>>57074964
No
There was time when C didn't exist

Fortran still superfast to do heavy math in physics and engineering, even if the code is crap.

It simply cannot be challenged for fast developing and calculations speed when you want to crunch numbers.

>>57075092
I suppose it is pretty fast... for a language that isn't C.

>>57075362
The point to understand here is not to over complicate life.

Why bother with when we can do parallel processing with little effort in Fortran.

>>57075472
The point here to understand is you're not a real programmer if you use anything that isn't C.

Doesn't GCC use F2C for compiling Fortran? Also I thought Fortran was still faster than C, it's not?

>>57075529
Fortran was never actually faster than C, but doing parallel computations was a little easier before OMP was invented.

>>57075509
C is an easy way
Real programmers use assembly

>>57075556
I have a hard time believing C was faster than Fortran right off the bat when Fortran had like a 20 year head start of optimization and shit

>>57070897

you need explicit types in source code for performance.

stop baiting, C used to be hella slow compared to FORTRAN when it first came about

For complexity, the usual things are:
Object oriented, class support.
Inheritance
Polymorphism
Garbage collection

You can be strongly typed (C, C++, Java) or weakly typed (Python, bash)

Performance can be measured with tests, but in general compiled programs run faster than interpreted ones. Minecraft is written in java but the textures and models are very simple, while really taxing programs like Fallout 4 and friends are usually C/C++

>>57070897
>language performance

That's not really a specification of the language so much as it is the quality of the compiler.

>>57078505
>Minecraft is written in java but the textures and models are very simple, while really taxing programs like Fallout 4 and friends are usually C/C++

I'm pretty sure it's the number crunching (like physics, AI, collision, etc...) that's the bottleneck, not loading models and textures. Even if there's some slight overhead on creating objects representing models and textures in memory in Java, once it's loaded into VRAM that's irrelevant, unless it's a game that does a lot of texture streaming.

>>57078505
>strongly typed
>C, C++, Java

I'd call those languages "statically typed", but strong typing means you can't get away with doing

std::string a;
return ((int) a);

The size of the games helps here. What is the size of Fallout 4? What is the size of Minecraft?
I run a few minecraft servers, the worlds are less than a gig. The client, Minecraft.jar, is 276K
Modern games are tens of gigs, with textures, models, animations, as well as physics solvers, path finders, event listeners, asset managers, etc, etc, etc. The complexity is on a whole different level.

>>57078505
>weakly typed (Python, bash)
Python is strongly typed.

Let's look at some benchmarks.
http://benchmarksgame.alioth.debian.org/

Highlights (from pic related):
>C is fastest, very closely followed by C++. As is to be expected, I suppose.
>Ada and Rust in top 5. Proof that adafags and rustfags aren't JUST memeing.
>Java at #5, performs at roughly half of C's speed. Shows that the "Java is slow" meme doesn't quite hold. Well, not fully, anyway. Probably still don't want to use Java for real-time embedded programs and stuff like that.
>C# is slower than Java, both on .NET and on Mono.
>Fortran is fast. C++-fast, even. Well, it CAN be, anyway. Its performance is kinda inconsistent here.

And here are the "slow" languages. Pic related.
>The fastest of these (on average) is, slightly surprisingly, Node.js. Still ~9x slower than C.
>High variance on almost all of them.
>PHP, of all things, outperforms everyone's precious Ruby and Python. Dafuq?
>Racket is noticeably slower than its sibling Lisp was in the previous language.
>Most of these "slow" languages seem to be, if I'm not mistaken, weakly and/or dynamically typed ones.

>>Racket is noticeably slower than its sibling Lisp was in the previous language.

>>57078899
The reason everyone hates PHP isn't it's performance. It's hated for it's insane typing system, and has historically had some terrible security holes.

ruby so you can write metasploit modules

>>57070897
In most cases languages aren't inherently "faster" or "slower". The implementations dictate this, as you'll find musl and glibc will come out with different performances for a variety of reasons.

>>57075529
Yes - for memory aliasing reasons, but stripping out the flag on C will cause them to perform pretty much neck to neck. FORTRAN booted off OpenMP, but C's pthreads is very precise and quite unforgiving, therefore many that work with more code opt for the simpler to use OMP.

And no, gcc has been using gfortran since the 90s. Overall, the state of gfortran is pretty good, pretty competitive with ICC, which speaks magnitudes considering not as much development surrounds it as C(xx).

>>57073282
that's...counter intuitive

Is anything written in C anymore? Any software that isn't niche or driver/OS development?

Don't tell me about microcontrollers, because that is today considered part of engineering rather than programming. It's right next to VHDL and assembly "programming". It's so close to the metal it qualifies more as engineering.

So what is C useful for today?

>>57079542
>tfw like C but know I can't write safe C so I don't use it

is python and perl the most god-tier combination ever constructed? why would you ever need to know any other languages?

>>57079603
performance?

>>57079603
perl is not as boring as python though

>>57072670
We use lots of things written in Fortran in our chemistry department. It's great for academic purposes: simple and fast, and since it's been well used for decades there's loads of literature on using it.

>>57072654
How am I supposed to know what your native language is?

>>57079542
OSes and tons of programs and games use C. C++ has unfortunately been forced on us because many graphics toolkits and game engines use C++ because of the OO fad, and people just end up writing very C-like C++ anyway.
