No, but only Javatards think every language needs to be OOP.

Why linux GUIs are so soulless?

If your language doesn't provide OOP provide proper polymorphism, traits, HKT or typeclasses
C has none. That's why C and Gotards don't understand DRY.

wow epic

At work, I'm responsible for a 30+ year old Motif program, hundreds of thousands of lines.

It's demoralizing.

I write tests for network switch C API. I need to learn Perl soon, because the testing environment uses it heavily, about 50% of a test is written in Perl.

friendly reminder there is not one non-autistic person who uses pointers or don't use garbage collections in this day and age.

Unit testing god awful OOP architected code. I spent more fucking time trying to get the god damn method to compile.

Are you retard?
The point is that these silly errors can be caught at compile time, which is great when you're implementing something you know too much about.

What makes pointers so confusing for brainlets? It’s literally just number, an index to the huge array that is memory.

This thing is a tranny, right?

absolutely terrible pointer syntax in C helps

Reasonable ABI.
Libraries that can be used by any language.

>reference: &mything;
>dereference: *mypointer;

I fail to see the issue here

If I have a five byte structure (bit field) of eight five bit bytes (unsigned chars) that encode numbers 0-31, what sort of application/ project/ program would be suited to using this structure for memory saving, given that when, say, characters are cast from these five bit representations and stored onto disk they are converted back into 8 bit unsigned chars?

because it's hard to imagine the purpose completely useless concepts.

What anout the people who bring your meme language to the metal?

>placate the nymphs

But user, variable names are pointers to the value's location.

what?

Attached: 1530456105927.png (211x239, 6K)

* is used to declare a pointer, to deference a pointer, and for multiplication
& is used to declare a reference (reference as in a reference type, which isn't a pointer) and get the address of variable for pointers, and for bitwise and
yeah sounds simple enough

>what are spaces

yeah changing the behaviour of an operator by how it's spaced isn't confusing at all

yeah, it isnt

Whitespaces don't have any affect on shenanigans involving C's * operator?

Literally just keep track of what you assigned as an int, and what you assigned as an int pointer.

AKA don't be stupid.

Found his blog posts about compression based programming. Really enjoying them so far. Thanks user.

>& is used to declare a reference (reference as in a reference type, which isn't a pointer)
C++ is not C

Or you could not reuse operators for completely different common tasks

Suggest better alternatives

You've discovered the actual hard part of programming, software architecture, the things you need to worry about when you're a good enough programmer than the "how" isn't a challenge anymore

I wouldn't have a clue, you don't need to be so defensive about it

based.
at what level are you?

you need to provide the type of pointer you declare so dereferencing with * isn't confusing unless you somehow forget you're working in a statically typed language. Which, given that you're a moaning little brat, you probably do all the time.

Tidying up a 350 line function that generates navigation grids, running out of sane things to name variables

Which engine?

>I don't know how syntax works
Spacing has nothing to do with anything. Whitespace is literally only used to separate tokens in C.
If * appears in the position as a binary operator, it's multiplication, if it's in the position of a unary operator, it's a pointer dereference.

So things like *a * *b works perfectly well, and still would work if I wrote it like *a**b

what lang

I only use statically typed languages
why are C programmers so butthurt?

Plenty of languages have "+" mean 3 or 4 completley different things, so I don't really see anything unusual about that.

blitzmax

unless you've overloaded the operator, no they don't

>I only use statically typed languages
lol dumb haskelet

wrong again

>addition
>string concatenation

Just to name the more common ones.

dumb javajheet

Pretty much all languages have at least two:
integer addition
floating point addition
(and yes, they are very different, one of them may not be commutative for example)
Then there are several langs which use it for concatenation (strings, arrays, lists).
And then some with very weird cases like adding an event callback to a list.

comparing integer/float addition to multiplication or pointer dereference is hardly a fair comparsion

This isn't really the problem considering the grammar rules involved.
If anything, I'd say one of the biggest follies of C is that syntax parsing grammar isn't considered important enough to be parts of basic tutorials. Understanding the difference between lvalues and rvalues and their context on operators makes a huge difference in understanding and retain-ability. Clear and Concise documentation that lists and describes every different situation an operator can be in, how it functions in that situation, and why this situation is different from others should exist for every operator.

keep trying, you'll get there someday

Floating point shouldn't be a part of C like it is today, the syntax should be mulf(f1, f2) like for sqrt and pow and everything else

dumb virgin

You're looking at it from the perspective of someone who's already used to it
Anyone can get used to any form of shitty syntax so long as it's distinct, that doesn't make it any less obtuse for someone who isn't familiar with the language or programming in general

Fuck. I remember those card backs

I don't think that's the angle I'm coming from. I've had to work primarily with Python for the past year, after all.
Languages are inherently obtuse until you become familiar with them. Syntax is just as important as semantics.
It's my opinion that it's much worse for an operator to be misperceived as having inconsistent usage (syntax) than it is to be misperceived as having inconsistent usage (semantic). If there were enough different symbols on a standard keyboard to have a different operator for all of the different use-cases, then it might be another story.
