What's bad about having the best bits of both? Both Java and python have a lot of good things going for them

pls delet dis thread. I'm at work and might be fired

What is the most versatile and the best programming language and why is it C#?

>>57632019
I like C# as my default language, but you also need to know other languages.

Gotta have C for the low-level stuff, because ASM is destitute-tier.

And you REALLY need to know Javascript in current year, regardless of your job role.

Pad skills with SQL and basic scripting language for common OS shells.

>>57632019
C++ and java

>>57632047
Is it really worth it to learn ASM? Considering it's architecture dependent. And what kind of low-level stuff are you talking about?

>>57632019
> What is the most versatile and the best programming language
For getting shit done, it's usually whichever one has the most libraries applicable to the kind of programs you write.

>>57632047
>And you REALLY need to know Javascript in current year, regardless of your job role.
lolno

>>57632075
> Is it really worth it to learn ASM?
How are you going to debug anything if you can't read asm?

Source-level debugging is a joke once you turn optimisation on (and turning optimisation on is usually when the bugs start to actually show up).

>>57632087
> You can't
Well, duh. If their sum is odd, then their average isn't representable as an integer.

>>57632104
Wait, so can turning on the optimisation change the semantics of my code? I mean, if my code works with optimisations off, will it not always work with optimisations on?

>>57632104
>turning optimisation on is usually when the bugs start to actually show up
you're doing it wrong

>>57632124
-O1 and -O2 are usually okay to run. >>57632104 is just an idiot.

-O3 is a bit shaky, though

>>57632104
>turning optimisation on is usually when the bugs start to actually show up
The fuck are you smoking?

An optimization shouldn't actually effect your program in a way that could cause a "bug", beyond fucking up performance on a particular call.

>>57632087
int avgC(int a, int b) {
if ((a < 0) == (b < 0)) {
return a/2 + b/2 + (a%2 + b%2)/2;
}
return (a+b)/2;
}
okay pajeet

>>57632138
>-O3 is a bit shaky, though
it really isn't, you probably have UB if running at -O3 is "shaky" in the slightest

>>57632087
>>57632087

I did what you asked :^)

Why are you still clinging to your hipster languages and not instead joining the Java master race /g/ ?

>>57632545
If you change

 (a%2 + b%2)/2;

to

(a&b&1)

and set -O3 in the options, it actually becomes reasonable

It's no secret that Java is the king of jobs.

However, I'd rather have plenty of jobs to choose from, but also a more enjoyable language, so I learned C#.

No regrets, I get paid a lot and barely work.

>>57632716
>implying there's a difference between Java and C#

>>57632733
They are vary different languages, particularly when you consider their ecosystems and compatible frameworks.

>>57632753
>vary
heh, tough luck on that typo

>>57631968

Greatest language.

I am writing a small C++ terminal application.

What is the most correct way for handling optional parameters?

Iterate through arg array and check for different params with a whole bunch of nested if statements?

>>57632828
Pretty sure there are libraries for handling such stuff. Just google it.

why did people even try to program in assembly

>>57631968
>objectively
cite your sources then

>>57632828
I usually check for number of params and param type first.

>>57632977
Because C did not exist or for some things C is too high level.

>>57632977
A lot of instructions aren't effectively used by the compiler, and the generated code is guaranteed to work on all computers. It is entirely possible to check for the architecture/extensions on the fly and run specific versions of code that run faster.

>>57632828
I would just make a function that iterates over argv to check for a flag

>>57632138
What are some common "mistakes" made by the compiler that would make -O3 and -Ofast not work?

idk brah

https://wiki.gentoo.org/wiki/GCC_optimization#-O

> -O3: the highest level of optimization possible. It enables optimizations that are expensive in terms of compile time and memory usage. Compiling with -O3 is not a guaranteed way to improve performance, and in fact, in many cases, can slow down a system due to larger binaries and increased memory usage. -O3 is also known to break several packages. Using -O3 is not recommended.
> -Ofast: New in GCC 4.7, consists of -O3 plus -ffast-math, -fno-protect-parens, and -fstack-arrays. This option breaks strict standards compliance, and is not recommended for use.

C++ or C#?

>>57633224
>>57633268
forgot to quote

Why don't more people use clang instead of gcc?

>>57633269
both

>>57633331
sorry but there are only 2 options:
C++
C#

>>57633281
I'm talking about specific bits of code in C that would "break several packages". I get that -Ofast is breaking standards, but there is no standards breaking in -O3, right?

>>57633346

Im just starting to learn programming in uni, whats the g approved c/c++ IDE for windows? beside VS thats too heavy for my shit laptop

>>57633408
Emacs and Vim both have Windows ports. Personally, I would choose Emacs

>>57633383
C isn't up for choice at this point it's already decided. now we need to determine this:

>>57633653
I've seen C++ and Java catch up on language features, and they look pretty decent nowadays.

In my opinion, the biggest differentiation is ecosystem, frameworks, and tools.

For example, Xamarin is C# territory, and Xamarin is a wonderful way to make mobile apps. It's scarily easy to get something up and running, especially with some Azure hosting.

Just jump in and give it a try.

Do some C++, too, if you feel like it, so you can compare.

You can do pretty much anything with either of those languages, but the languages have different syntax and features, and (most importantly) frameworks that they work with.

>>57633830
VS is the proper dev experience, to be certain. Latest version of Roslyn with all associated IntelliSense features ready to go. Integration with Xamarin and other frameworks you might be interested in. And the new version has a much lighter-weight installer that only gives you what you want.

However, many people use VSCode, and Rider is now out, so it could be worth looking into: https://blog.jetbrains.com/dotnet/2016/11/21/jetbrains-rider-public-preview/

>>57633843
>What does an IDE do that Emacs doesn't?
It depends on how many hundreds of addons and third-party tools you're willing to frankenstein onto Emacs.

>>57633843
Be an IDE?

>>57633870
So would you rather have a unitary conglomerate like Code::Blocks than a modular and utilitarian system like Emacs?

>>57633922
I'd prefer not to fuck with and maintain 60+ addons and other tools when Visual Studio has those things ready to go out-of-the-box.

>>57633952
What do you do in Visual Studio that you would need 60+ to do?

>>57633867
By new version you mean the 2017 one?
>Rider
I'll try that as well.

>>57633762
Inconsolata

>>57633973
You can try out the 2017 RC now, but I'd use 2015 until it's actually released.

That being said, C#7 has some really REALLY hot things to work with, like tuples, inline functions, and some pattern matching. There's other super nice things like filterable IntelliSense, too.

To get those, you have to go ahead and use the 2017 RC.

>>57633967
Depends on what I'm working on that day. I'm not going to bother listing 60 things, and I'm sure you'd just dismiss anything I list as useless or something something pajeet.

Things like Paste Special, which allows you to copy JSON and paste a working C# class.

Lots of built-in code-snippets, like being able to type "prop", or "ctor" and hit tab twice to autogenerate properties and constructor, respectively.

"Add Service Reference..." which allows me to paste in a SOAP URI and it autogens a library with classes so I can easy consume that API.

Solution Templates of all kinds, Xamarin integration, drag-and-drop GUI creation, easy dialog-based creation of database connections with things like Entity Framework, GitHub/VSTS integration with work item assignment on version change control, Peek Definition, lots of debugging features, particularly with the Autos window and being able to drag and drop my breakpoint to rerun a block...

Some of these things may be available in something like Emacs without addons, but I could keep going.

>>57633967
Snippets, quick replacing, intellisense, model/image viewer/editor, Nuget, debugging, profiling, 3rd party services, auto code source, server explorer, web dev tools, references, etc..

>>57631945

What IDE should I use for Python 3 on Raspbian?
I'm teaching myself some basic skills, but IDLE really sucks. There are so many IDE choices that I don't know where to begin.

pls no vim or emacs

Pycharm is good from what I heard.
But you should really learn how2vim.

>>57634118

emacs is basically an operating system. it's easily an IDE

>>57634163

I have no intention of becoming a software designer. I'm a mechanical engineer by trade and I'm learning Python for hobby projects.
A little bit of auto-complete and error checking would go a long way.

>>57634137
>>57634144
Thanks for the advice. I'll give those two a look, and I'll (begrudgingly) put more time into vim.

defend this

>>57634206
Vim has a strict learning curve and setting it up with autocompletion and error catching is a chore. Unless you are going to be a serious dev, you don't need to learn vim. It's just bragging rights in the programming community to be able to use it. But it's not elegant or helpful.

>>57634207
>Not even a C++ expert can figure this out

C++ is a big fat mess.

>>57634230
>. It's just bragging rights in the programming community to be able to use it. But it's not elegant or helpful.
This, using vim is nothing but an epeen growing exercise

>>57634230
Vim is useful for me because I do all of my programming through my VPS, and so cannot use an IDE or text editor like sublime or atom. Also, on a computer with such little ram, a webkit-based text editor like atom actually takes up a lot of memory and slows my machine down. Vim really helps with that, and honestly you don't need to learn 90% of the commands and keystrokes. I haven't added any plugins either, just vanilla. Maybe I'll go install nerdtree though...

>>57634230
Vim is useful if you use command line tools during development, which I do. It's a pain in the ass to switch from an IDE to gdb or perf.

I've seen "Intro to Programming 101" classes offered in multiple languages.

But you have a point; after that, it was something like "Database Administration Programming" and they'd have a particular language like C# that the class is taught in, with the expectation that you know at least one similar language's basics already.

>>57634477
Yup - C.

>>57634442
Yes. No.

>>57634442
>>57634460
Yeah, they have some computer classes and Java/Python is one of them. It's a small school, and I figured learning something like this would be good anyways.

Probably take python.

Java classes will try and brainwash you into thinking the language is decent. Python knows where its bounds are and just teaches you some very basic programming.

Avoid OOP. Sadly both of the languages have a lot of support for OOP.

If you have Go/C/[insert functional language here] as options take that instead.

>>57634582
You sound fun at parties

>>57634632
You need to know OOP is you want a job. Just don't think it's the best thing ever and a solution to every problem like most programmers do.

My intuition is no.

>>57634632
I don't. I have some interest in programming, I tried to do SQL before, that went ok. If i can pass Python then I'll probably try and take a different language at a different school. Either C or C++ or something like that

>>57634714
OOP covers several pages to do the same thing functional or imperative programming does.

It's not as simple as code examples. It's abotu how you design software. Functional programming is focused on sharing as little state as possible. You have functions that work more like math functions, they take parameters and produces results, that's the goal anyway. Imperative programming says next to nothing about how to structure a program. OOP is a programming paradigm that's too difficult to explain effectively in the remainder of this comment.
Here's someone who's trying to compare:
https://www.youtube.com/watch?v=V6VP-2aIcSc
I don't think it's all that useful. He has other videos critiquing OOP which are more productive to look at.

well i think it's the companies fault for hiring one person to make a piece of code that nobody else even understands.

like the team is dependent on this internal component that is entirely important, and massive, that was entirely written to be maintained by ONE person? that makes no fucking sense.

I'm not trying to say you don't need 60+, I'm just curious about what you would need them to do.

Yeah, I would imagine C# is very non-standard and Windows native, and would be pretty hard to use in Emacs. I use C++ in Linux without a graphical interface, and I haven't ran into any problems.

The only things you listed that I used in Emacs are Git integration (magit) and auto completion (can't remember the name). The flexibility of Emacs Lisp makes the others possible, but those seem niche enough to be made personally.

>>57634102

>Intellisense
You have another
>model/image viewer/editor
Emacs might be able to do this, but this seems to fall outside of what an IDE does (assuming you are using a standard language like C/C++, Java, Python, etc.)
>debugging
If you are using a compiling language, you can use Valgrind or GDB to check for errors in a terminal window (inside of Emacs), and search for the errors and fix them in another.
>Profiling
I never profile inside of the IDE itself, since I use Valgrind and kcachegrind
>auto code source
If you are looking for definitions, then use rgrep
>server explorer
There is built-in SSH support (SCP), and you can use another terminal window to open whatever you need to use
>web dev tools
Emacs 25 has a builtin web explorer. I will admit, you might want to get one or two addons for this

rgrep

love you bae

>>57635032
well uhh... first you would assign a variable to 0. wait no 1. you assign it to 1 and then... uhh... you need to loop until you hit 100. Wait is that including 100 or below 100? a-anyway. You need to do an if statement to check if it's a multiple of 3... wait 15 would be faster. So, wait i didn't name my variable... let's name it i. so check if i mod 15 equals to zero, print fizzbuzz. Then i mod 3 equals to zero. Print buzz. wait... are you supposed to print "fizz" for multiple of 3? wait. where was I again? I'll just start over.

It probably would have taken 35 minutes on its own

>>57635120
Maybe not the core language, but a lot of the extensions and addons might hinder it (especially whatever the GUI is)

I'm working on something really cool, but really simple, so I don't want to tell you guys what it is because then someone will steal it...

There's no standard cross platform UI for C#. If you're using linux you can use GDK+, which is cross platform.

Most of them can't fucking do it.

>Yeah, I would imagine C# is very non-standard and Windows native, and would be pretty hard to use in Emacs.
Not at all.

Nearly all of the frameworks and the compiler itself is completely open-sourced, and works just fine with whatever editor you want to us.

Also, I love how you only responded to the low hanging fruit of VS features, along with "I just use another program to do that" responses which only serves to prove the point that VS has more built-in, and less 3rd-party pieces and addons to maintain.

Overall, it's extremely clear that you're trying to justify your way of doing things.

I'm not saying an IDE, or a series of disjointed text editors + addons, is the best solution. The point is, I'd rather have one monolithic application take care of virtually all of my needs as a developer, rather than having to fuck with many addons and other programs (e.g. Valgrind, GDB, kcachegrind, unix shell commands)

That's the real disagreement here. I'm not saying that Emacs itself can do everything Visual Studio can, but instead that it doesn't have to, and you can rely on external applications to do the same job.

Xamarin, along with Xamarin.Forms and its platform-specific implementations is all open source and free now.

.NET Core is a lightweight, portable .NET implementation, open source.

Mono is a 3rd-party (although maintained by many CURRENT Microsoft developers) implementation of the .NET Framework.

The compiler for C# and Visual Basic, Roslyn, is open-source and cross-platform.

Microsoft has plans to unify .NET with .NET Standard, which, from my understanding, will be open-sourced as well.

These are all MIT licensed, which means anyone can take that code and create their own implementations of the languages and frameworks as they see fit.

Mostly, i think, because JS is dynamically typed..

thx i just checked the 4chan faq after i heard the keyword tag and "code"

YOU are not programmerS

Don't really see how. Javascript takes care of all the stupid shit you have to deal with in C++ and lower level languages so you can get down to the actual design aspect instead of dicking around with reinventing the wheel.

Javascript is the pretty much the most flexible language ever

"no"

>>57635846
C++ is my language. I don't like JavaScript.

JavaScript is still a programing language. So please fuck off, would you kindly.

>>57635873
YOU don't know what programming is.

in c++ is there no way to dynamically make an array of objects the require a parameter?
should i just use a vector for everything? I keep running into difficulties with plain arrays

int returnsOne() {
    return 1;
}

int returnsZero() {
    return 0;
}

int isEven(int n) {
    int *(*fptr[2])();
    fptr[0] = &returnsOne;
    fptr[1] = &returnsZero;
    return fptr[n&1]();
}

That's what makes it so messy.

>>57635879
what do you mean with indentation?

Foo* p = new Foo[N](x);

Or better:

 std::unique_ptr<Foo> p(new Foo[N](x));

with languages like C (excluding C# because windows only) you can do the same things you can do in javascript (except it not being a programming language) with just a little more effort, but when it comes to more abstract things like socket programming you have many advantages with low level languages (speed, simplicity, actual understanding of the code...)

excluding C# because windows only
why is that a valid reason to exclude it from your list? Maybe exclude it because it's more similar to Java than C or C++ and high-level AF? Lol, also, a lot of socket programming is done in Java or even Python. Have you read a networking or operating systems textbook?
