How can you trust Microsoft to anything right if they can't even support C which should be the easiest language to implement?

>>61289391
>MSVC
It works perfectly.

>>61289444
They do support C89.

>>61289456
Not really. fopen and fclose are not totally supported, the current implementation is buggy.

>>61289456
they don't support C

>>61289216
Honestly I get more segfaults with C than assembly.

>>61289485
C89 is the only C that matters

>>61289484
>fopen and fclose are not totally supported
good. they shouldn't exist at all.

how do I go about understanding g++'s STL implementations. I read what en.cppreference.com has to say but it doesn't have much towards any actual implementations. I'm reading the code but good lord it's barely legible. I understand how to use the containers well already.

maybe I need to start with understanding STL iterator usage?

I just want to have the watch window dereference a pointer and show me some number of elements past the pointer, as if it were an array.

Basically the temp[0]... thing but not so onerous.
I've found that casting the pointer to an array type seems to do that (I can now collapse/expand that watch variable) but it is clearly not showing me the right values. (as you can see in the picture temp[0] doesn't give the same result in both cases).

I can't tell why.

Go targeted C++ users. Python and Ruby users are the ones who actually made the move, and that makes a lot of people.

>>61290648
Do you mean the inner (while) loop or the outer?
Assuming the typo is removed:
Right now the while loop doesn't seem to make any sense since

while(!record.contains(lastString)); { //Typo here, remove the ;
    count++;
    [...]
    lastString = String.format("%04d", lastCalc);
    record.add(lastString);
}

Quite obviously record will always contain lastString past the first iteration. I'm not sure what the intent of that loop is, haven't read the problem but it should be an if statement if this is what you intend. Because it's functionally the same.

thanks, i didn't see that typo.

i mean the bunch of loops in the last for loop.

yeah, i see that it wouldn't work the way i want it to the way i have it...i'm just stuck

intent: check if the most recent value of lastString is a repetition

i THINK the way that would work would be to have lastString added to record, then go through the loop again–lastString has changed–check if its unique or not...repeat until it is

but lastString doesn't seem to change...and i'm not getting what i should do with the condition/loop to get it to run more than once, while still adding lastString values to record and checking the latest lastString against record.

Your pseudorandom function doesn't work in the first place. My advice is to make a new method just for calculating that and test it. Divide and conquer

Test cases (input -> output)
1 -> 0

4100 -> 8100
8100 -> 6100
6100 -> 2100
2100 -> 4100

Because it's a very good first language that gives you a solid understanding of modern computing.
If you learn C, then Lisp, then move on to whatever else you want, you'll be in a very good place.
Instead, retards start with Node.js, Ruby on Rails, and muh pseudo-code Python, and fucking suck at the fundamentals.

>>61292830
It's actually because assembly is 99999x easier to debug.

Question for you programmers:

Do you indulge much in inebriation, or are you straight edge?

Just wondering if there's anybody that actually maintains a balance, or if it's best to avoid altogether.

I am genuinely interested in learning C, but what's holding me back is the fact that I can write code in modern languages that does the same shit in a fraction of the time. Things that can be done in Python in a couple lines often seem to take up 50 lines in their C equivalent. Sure the execution is faster, but is it really worth the extra effort?

>>61292988
You will better understand what your computer is doing without getting lost in assembly. It's worth it for the understanding, even if you don't like it (aka the LISP argument)

C is just a von neumann machine though. Computers haven't been von neumann machines for a long time. They have caches and registers and pages.

Hell even assembly abstracts away caches.

I used write everything in Common Lisp but I don't really the state of cl implementations.

I find sbcl to be the most tolerable of cl implementations. Clasp is incomplete but also promising.
Over time I've learned to use and appreciate Ocaml, despite that it is in spirit very opposed to the of "open-world" freedom of Lisp, in exchange of more rigorous checking of exhaustivity. Haskell is similar.

char value(unsigned char v) {
  unsigned char mask = 0x02;

  printf("%u\n", value(v));
  return 0;
}

I don't know if I'm doing it right, but why does it print the 2 instead of 1?

>>61293721
ugh it's 0x04, but not 0x02

>>61293721
0x08 is the 9th bit, numbering starts at 0 with computers

Shit, sorry. v is supposed to be 10 here, not 29.

>>61293733

>>61293733
It's just testing if the bit is present.
If the bit is set then the result is 2, if it is not set then the result is 0.

printf("%u\n", value(v) != 0);

because != is converting it into a 1 if it's a 2. you need to do the right shift if you want it to be purely bitwise. read my previous comment >>61293696

I like Java's interfaces. The really help cleanly separate the interface from the implementation. I like how the docs list all known implementing classes of each interface.

>>61293844
the second bit is 2, that's how binary works, so if you just want a true or false (1 or 0) answer you need to check if it's not 0

is there any good approach to reading and understand the source of some big program that has tons of files and shitloads of includes all over the place

Jumping into C++
I made a 2^(2^n) calculator (off by one Fermat numbers)
tried to get to 2^(2^40) a 330 billion digit number, but I only managed to calculate 2^(2^33), a 2.58 billion digit number
I don't know why I wanted to, it just felt interesting to try to find the number

It's pretty relaxed and boring overall, with a few spikes in activity every now and then. The job is occasionally interesting but most of the time isn't, but I'm very happy with the conditions, workload and most importantly the pay so far. Got a promotion this year too.

>>61294175
"jumping into C++" is a book
it just explains everything quickly and succinctly. if you wanna figure out how something works in a deeper way the book assumes you'll stop and try some practice problems, it doesn't babysit you and hald your hand through explaining stuff. it was OK, not great, not terrible, just OK.
>Do you have a job with the language now?
still in college m8. read the book in HS


tho, on a sidenote, that wasn't my first programming experience. I had petit computer on my DSi. that language had no tutorial or book, just documentation of functions. After a lot of trial and error I had a text based adventure game going, it was shit.

>>61294547
inconsistent standard library function naming and argument conventions
weak typing makes error detection nightmarish (many functions return false on failure but may return 0 on success)
disgusting OOP syntax. self::$static_variable but $this->instance_variable
Your only built in collection type is the array. Which is also a stack. Which is also an ordered hashmap.
Objects are reference types even though everything else, including arrays, are value types. Also, references already exist but are broken.

WHAT THE FUCK DO I ACTUALLY DO ABOUT SIGNEDNESS?

this fucking shit triggers me so fucking much.

say there's this fucking function that takes signed, but i actually need to show in my own function that argument can logically be only signed. or some other shitty situation where signs mix.

how do i fucking solve this?

do i cast those situations? do i disable the fucking warnings altogether? what the fuck do i do? and those fucking size_t god almighty what the fuck.

>>61294857
what the fuck are you saying

>>61294857
If a variable of you code only accepts positive values use an unsigned type, always. If external APIs are specified with signed types it's their problem. You don't have to use casts.

I'm bored /dpt/, give me a challenge

if only.

what do i do when i need to call some function that uses signeds? do i cast? do i actually put those fucking casts everywhere? because otherwise it's either no warning or having your warning shit up by this permanently.

you know very well that we're all gay here.

but seriously though, how to deal with signs? static_cast everything? add a function that checks conversion overflows?

unsigned was a mistake.

>>61295086
When the fuck do you need to cast an unsigned number?

You aren't compiling with wall wpedantic are you?

>>61295044
for fuctions that return potential error codes I do it like this usually, if that's the problem. I'm autistic about signedness in C and don;t usually encounter problems other than that.

size_t n = read(fd, buf, size)
if ((ssize_t)n == -1)
/* error handling*/;
/* proceed with unsigned n */

>>61295118
i am compiling with Wsigned obviously
>>61295176
that's an old style cast. those are shit because it's hard to search for them.

Is there any resources where I can learn C++ with functional programming?
