>>52056834
It's not worth playing with pointer arithmetic unless you intend to indiscriminately process what's in the array, like using while (*str) instead of while (str[i] != whatever).
Write a strrev function and if strcmp returns 0 true for the reversed and original string , return true.

This is technically undefined behavior according to the C standard, but the most used compilers will do what you want it to do, which is to retain the value of the last defined variable and print out the value in the type of what you are calling from the union.
I wish they would seriously just port over the reinterpret_cast from C++ which basically defines this behavior clearly in the standard to C. Never know when some rogue compiler decides that it wants nasal demons instead.

You could probably redefine your PORTD by using some awful define/undefine hacks.

Your opinion is shit though. "." means compositing functions backwards. Less intuitive to read the flow of logic.

>>52057818
If you want the .NET ecosystem, you definetly want F#. Otherwise I'd give Haskell the edge.
>>52057818
>real talk, is F# the best functional programming lang currently?
It depends what you want to do. But imo it's the best get-shit-done FP language.
The main difference between haskell and F#, is that haskell is a pure function programming language and makes it very hard or impossible to do imperative or object oriented style programming. That can be very interesting to work with, but not necessarily that productive for most kinds of programming problems. F# just provides FP as another way of solving problems, but lets you use imperative or OO programming paradigms comfortably when they make more sense, while still encouraging you to use FP first.
>>52057835
How do they differ from interfaces?
>>52057871

yes, it works perfectly on everything that supports C#.
>will it get me a code monkey job?
Not really, though it will look good as another language on your CV, and learning it will improve your C# code, of which there's plenty of jobs in. There's not many jobs for FP languages. But if you get a job in C#, I'm told they'll often let you use a some F# at times.
There are some F# jobs, mostly in financial services if that interests you.

It would sound like a good idea. C as a first language is something I recommend to everyone, and after that, anything goes.

A snake game, the snake is a string of text defined by the user and its food is the next character in the string.
For example:
With the text "memesnake" the snake would start out as:
- "mem" and its food would be an "e"
- when it eats the "e" it grows to "meme" and its next food would be an "s"
- when it eats the "s" it grows to "memes" and its next food would be an "n"
- when it reaches the end of the string it just repeats until the user dies

C's good as a first language if the person learning is willing to struggle and has rigid deadlines to hit like in a class setting. If they have issues they'll basically be forced to seek help and they'll learn fast.

>>52058502
List monad is a bit more subtle that that. You can't substitute bind for map anyways, it doesn't make sense with the types.
The list monad is useful, for example, if you have a function with N solutions instead of exactly one. You can compose those functions together with bind so that you end up with all the possible permutations (though a set monad may be more appropriate so you don't end up with duplicates).

C# is actually my language of choice. I would never use it for the web because that would be insulting to it. C# was the main language I had in mind in my last sentence though. Outide of work I don't care much for the web
I might look into typescript and coffeescript though.
>>52058647
oh, you have a better language for web backend anon? Let's hear it. I bet this will be good.

>>52058703
well, it is the best for web backend by far. Not sure why you're opposed to using it. Don't use coffeescript or typescript for server side, unless you have a very compelling reason to. For example.. you work with a team of mongoloid JS devs you know well will never learn C#.
>>52058626
Here's an example of where it might be useful.sqrt2 :: Float -> [Float]
sqrt2 x
| x < 0 = []
| x == 0 = [0]
| x > 0 = [sqrt x, negate $ sqrt x]
You could then make a double square root function that still only produces real roots, only composing the original "sqrt2" function with itself.sqrt2x2 :: Float -> [Float]
sqrt2x2 = sqrt2 >=> sqrt2
-- sqrt2x2 x = sqrt2 x >>= sqrt2

Yes, monads have a category theoretic meaning, but it's not really useful for programming especially at your level. They're basically just a design pattern, which ends up being so ubiquitous that Haskell has special syntax for it (like arrows, but I'm not gonna get into that).
>>52058630
Well, it doesn't really do anything special or unique. It has concurrency focus sure but who cares really. Plus the syntax is deliberately contrarian.

If you want an even better language use F# btw. It's easily the worlds best language. It's just a meme language in the sense that you won't get work using it. But it's great for personal stuff.

No, C# is just one more option. The fact you think C# is the best language for web backend is just your opnion/personal taste.
>>52058732

Yes.
I don't want to use it because I don't want to develop for the web. Due to certain circumstances I'm stuck with node, or go at work. I suppose go probably isn't that bad really, it just seems to try and be different for differents sake.

I've played around with it. For now I still prefer C#, just because I'm more comfortable with the oop-first paradigm than fp-first. I'm sure overtime that will change as I get better. I do need to learn language that keep me independent of the microsoft stack too. I've been playing around with the idea of rust.

Yes, when someone is representing themselves as part of the F# community, then they shouldn't be a fuckwad.

Oh God. Just kill yourself anon. These are literally the worst fucking ones. You're recommending fucking JavaScript and fucking ruby?

It's based on the fact that its:
Statically typed
Strongly typed
Fast
Generally very nice to work with
lots of modern language features like lambdas and async/await
Very good tooling
Very mature
Great ecosystem
Strong job prospects
All good things none of those pieces of shit you listed have

F# is far nicer for OOP than C#.
>>52058774
Node isn't scalable, has no actual server functionality without downloading it as packages and is based on one of the ugliest languages of all time.
Rails is literally (compared to c#, java or go) an order of magnitude or more slower. Even compared to python and node it's an average of about 5 times less performant.
Django suffers from similar problems to rails.
Java is pretty good overall (as a platform, not so much as a language) and slightly faster than c#
>>52058865
Alright autist.
Go pretend you're a woman in tech and claim that all the F# maintainers verbally raped you on IRC or something.

€2,000. It is christmas after all. What they pay me doesn't matter though, I'm still correct.
>>52058846
I know. That's why I said fp-first and oop-first.
Rust is interesting. It's a more elegant c++ with some interesting functional paradigms. Of course it's basically useless for jobs
>>52058902
... nothing is preventing you from using F# and not touching fp
>>52058910
Why would I ever do that though.
Why use a language if, not only are you going to write it non-idiomatically, but without it's greatest feature.
>>52058848
Actually Java has hall of these features, the only exception is the features missing. And also, Java is faster, has more libraries, is more open, has better tooling, better profiling, tools for static code analysis (things like checkstyle and findbugs), etc... And JavaEE stuff also has strong job prospect. In my opinion, the ecosystem of Java is better than the C# and .NET general ecosystem. The only great advantage of C# is that it's feature rich.
>You're recommending fucking JavaScript and fucking ruby?
Actually I didn't recommend any of these (altough I like Ruby a lot), just said there are alternatives.

List.map (sqrt2 x) sqrt2
does the same thing, though, doesn't it? So where's the win here? How is bind not literally a synonym for apply in the general case and map in the case of collections? How are monads not literally a buzzword that means precisely nothing?
>>52058932

>Holy shit why do people keep fucking saying this?
>Like extra features subtract
What the fuck are you talking about.
>>52058993
language x has features a and b
you want feature b
>why would I use x, it has extra feature a
>>52058958
It doesn't quite do the same thing, because if you simply map it you end up with a list of lists. Bind is actually defined in terms of mapping and joining, where join "squashes" two layers of monad. For the list monad, that means concatenating all the lists into one. It's just typically easier to define a monad in terms of bind rather than join, although I wish Haskell gave you the choice.
The monad instance for lists isn't really very interesting. Monads aren't really interesting in general, they're just a common pattern that can do a few special things like emulate linearity to allow side effects (IO, for example), and they have syntax.
>How are monads not literally a buzzword that means precisely nothing?
Because they are a construct in category theory, where the same general structure and laws apply. But abstracting these into a type class makes it possible to write generic functions that work with any monad, such as mapM, which is almost like a side-effecting for loop.
>>52059021
That's not even close to what I said you idiot.
Do you not know what idiotmatic is?
Daily reminder that if your language of choice is not on this list you should probably give up and kill yourself:
- C++
- C#
- Lua
- Python
- Elixir
- Haskell
- Bash

>>52058936
>only exception is the features missing
Which is why i left it out.
>And also, Java is faster, has more libraries, is more open
Hardly any faster. It has nothing that tops ASP.NET for maturaty. The CoreCLR is MIT licensed. ASP.NET 5 will launch soon with first class support fo CoreCLR on OS X and Linux. Far more open than the Java offerings.
>has better tooling
Are you kidding? Every Java IDE i've used has been garbage. Always sluggish, bloated and buggy. VS is the best IDE there is by a long shot, especially for C# dev.
>better profiling
Not at all
>tools for static code analysis (things like checkstyle and findbugs)
C# blows the doors off Java for that kind of shit. VS on it's own is good at it, but there's also magic stuff like resharper and tons and static analysis tools.
>the ecosystem of Java is better than the C# and .NET general ecosystem
It's bigger. But the quality does not match what C# offers on the web stack.
>The only great advantage of C# is that it's feature rich.
That's putting it mildly
- working generics
- structs
- async/await
- properties
- easy native interop
and tonnes of other small things that tend to make C# code bases much more concise and more readable.
>Just said there are alternatives.
I asked what would you recommend instead and you listed those you dumb shit. I know they are alternatives. You're either too dumb to know why those are shit or too dumb to read.

make a Point class in C#:class Point {

public void Point(int _x, int _y) {
x = _x;
y = _y;
}
}
same thing in F#type Point(x, y) =
member var x = x
member var y = y
though this is immutable, it's a little more work to make mutable but not much. But you get an idea of how much cleaner, readable and concise this is. C# is full of redundancy and opportunity for mistakes. F# is nice short and declarative, yet compiles to pretty much the same thing.
You can do inheritance and everything else in. F# too, you just need to look up what you need to do. Everything ends up nicer.

The JVM is the reasons Java and all other JVM languages suck shit. The CLR is basically the JVM with all the broken shit fixed.

>>52059171
>no TCO
It sucks balls.
>>52059324
Not syntactic sugar. The semantics of F# are wholly different from those of C#, but they use the same backend (.NET) so interop between the two languages is simple.
>>52059324
Might as well write directly in IL then. C# is just syntactic sugar for it.
>>52059324
real programmers use assembly. C is just syntax sugar
>>52059365
If you use a non-optimizing C compiler, probably.
Have you seen the massive amounts of optimization GCC performs?
The code you write has very little to do with the assembly GCC spits out, especially on the higher optimization flags.

Is F# a relatively new thing?
I haven't been in /dpt/ for awhile and I haven't heard of it before tbqh.
>>52059234
I asummed byt "better" you meant actualy paradigm changes, but what you showcased is the exact same oop, just in the more compact format of f#. Not that that's a bad thing but it's misleading to say the least. By all accounts the only difference between them is mutability and the constructor being part of the declaration. There's no fundmental difference in the interpretation of how oop is supported (like, say, how swifts oop is quite different to python)
>>52059406
optimizations will only do so much. people have put a lot of work in to compilers but they still don't achieve anywhere near their potential.
even with the highest optimization level C will run 10x slower than hand written assembly
