Reindeer *ptr = (Reindeer *) malloc(sizeof(Reindeer));
char *str = (char *) malloc(sizeof(char) * strlen(nme));
strcpy(str, nme);

First, decide on a good GUI widget framework that works with you're language. For example, in you're using C++, then QT is the most popular choice.
From there, use the included designer tool to build the look of you're GUI items, say dialogs.
Then you use the appropriate mechanisms to hook the callbacks from you're GUI items events, say button-clicks, into you're code's functions.
I hope all that made sense anon. QT uses an approach for this they call 'Signals and Slots'.

Since I'm only an engineer I'm not very good at programming but I make do.

What the fuck, are pointers nowadays called "raw" because some other shit like "smart pointers" are available?
Fuck this shit, they're pointers since they point to memory and that's it.
>>51857316
yes, they expose raw memory addresses given to you by your OS
the only thing rawer is writing your own kernel that accesses memory directly
pid_t pid;
pid = fork();
if (pid == 0)
{ /* child process */
fork();
thread_create( . . .);
}
fork();
How many ORPHAN processes are created?
Then, how many UNIQUE threads are created?

I am learning C# because it is the basis of all modern programming, or so they tell me. I only want to made little 2D arcade like games, should I bother? If it is only going to be a hobby thing, should I instead use something with a front end like unity or game maker instead? I am not so good with logic I think. I am trying not to think about it too much.
>>51857763
From perspective of the language, they are raw pointers pointing to raw memory space. What OS does with them is of no concern for programming language.
Particularly, calling them virtual is completely and utterly wrong because same code can be compiler for system with virtual and direct memory access.
>>51857769

They're's certainly a good argument to be made about using native over interpreted, but you make a good 'point' about all the raw pointer use out there. Especially when they're's modern C++ available.

For the same reason the term 'naked new' and 'naked delete' exist.
As to you're complaint, putting them within abstractions that afford RAII automatic resource management is generally the superior choice. Humans (especially C programming humans) have shown that they are often not very good at managing resources properly--especially during error conditions/states.
The runtime system never misses a beat with it. But you have to take proper advantage of that system first.

you're kind of thinking about it wrong anon.int i = anything_in_the_world_youd_like();
will still only be a single int, as you've declared it to be.
(in this case a '0', since that's what you're function returns).
On you're system, apparently ints are 4 bytes in size (commonplace atm).
The memory layout of any function isn't generally relevant to the size of it's return either, but that doesn't matter since you've explicitly declared i to be an int. That means it's an int and only an int.
Hope that makes sense anon.

recursion is for fucking fags that think they're so clever for using such a "trick". the natural (naive) way to compute fib(n) would be to go from 1 to n like 1 1 2 3 5 8 13 21 etc using normal iteration. not fucking backwards using recursion; try writing it out on paper, it's a fucking ridiculous and inefficient concept.
>>51859355
No, I'm just becoming more and more suspicious that people actually believe stuff like this: >>51859369

>>51859380

it's not a matter of belief. it's fact.

you must be trolling. recursive fibonacci is several orders of magnitude slower than iterative.

RETARD I'M NOT EVEN TALKING ABOUT THE PROGRAMMING ASPECT OF IT
I'M TALKING ABOUT THE "INTUITIVE" WAY TO COMPUTE IT
AND THE COMPILER CAN'T FIX YOUR RETARDED "ALGORITHM"
>>51859396
Sure, if it's done naively. With a histomorphism recursion scheme (automatic memoization) it's trivial to implement in O(n).fib :: Int -> Int
fib = histo phi where
phi [] = 0
phi [_] = 1
phi (x : y : _) = x + y

sorry anon, you were right. I shouldn't have linked to this thread...
>>51859422
KILL YOURSELF
>>51859396
>>51859422
And the best part is that because of purity, "histo" could simply be implemented to store and reuse the list of results that it internally generates.

fib(8) using iteration: 1 1 2 3 5 8 13 21
fib(8) using recursion:
fib(8) = fib(7) + fib(6)
fib(7) = fib(6) + fib(5)
fib(6) = fib(5) + fib(4)
fib(5) = fib(4) + fib(3)
fib(4) = fib(3) + fib(2)
fib(3) = fib(2) + fib(1)
fib(2) = 1
fib(1) = 1
fib(3) = 2
fib(4) = 3
fib(5) = 5
fib(6) = 8
fib(7) = 13
fib(8) = 21
which is more elegant and useful?
>>51859502
Using a histomorphism is the exact same thing as doing it with iteration, except the memoization is handled automatically.
>>51858815
No, I'm busy with own shit and it's minor, it's now in master ;^)
I'll fix it when I'm in the module and can remember.
>>51859457
>being THIS smug about being able to think recursively
you are not smart for thinking recursively, fucking pleb.
>>51859528
Not him, but recursion can easily give you the performance of iteration while being far simpler to write (no juggling accumulators, stacks, etc.)

Are you trying to false flag anti-FP as being universally too stupid to come up with an argument to support their beliefs? Because you're doing a good job.
>>51859613
the same way you do in java anon, with the avg() function.

For real though you really don't want to be switching branches mid-work, build and having to run through all the CI stuff just to validate a one line change that you can fix next time. We're pretty busy these days.

Hello /g/, can anyone help me with some C programs?
It is very urgent and I promise I will make it worth you while if you help me, just give me your Steam ID.
First one is:
Write function formarray which on array's position where the minimums are maximum's get written and vice-versa.
Within the function formarrat call for funcion minmax which returns the minimum by the reference of maximum.
Write a C program which allows input of the entire number aray X of n element, and then calling for function formarray which dpes the transformation of the array.
Excuse me for my bad English (translating), I'm Polish/Russian
>>51859674int average(int a, int b)

Baby-tier beginner here, currently learning Java. Not sure if going to stick with this one, but I have a dilemma. Job market-wise, should I:
a) grind one language until well above average skill
b) learn parts of 2/3/4 languages that differ from each other to become more versatile
>>51859899
Both
>>51859724

never mind that's actually correct, i thought i had it set to average(-2, -1)

A segmentation fault is basically you attempting to access data that you have been locked out of. Like when trying to access dynamic addresses from within a loop. Or like trying to access a thread that closed before you reached the thread.join call in your code.

Hey guys, was looking around on stack overflow, and apparently someone patented this in 1996.
This raises a question though -- if the compiler generates equivalent code from using modulo and division operators, is it still illegal?
>>51860457
Thanks!
>>51860460
The patent is for a way to this in one operation / hardware. The algorithm itself is not patented.

Oh I lie, I was overseeing someone's work during summer and he was Polish and his code was pretty good.
Indians just write trash AFAICT.

indians are legit stupid as shit. it's a third world country and a lot of people literally shit in the streets. even the ones that aren't complete poorfags have shitty DNA and eat food that lacks in nutrition. in their culture it's normal and accepted to tell lies and defraud people. their education focuses on memorizing things, they can't think for themselves. you can teach them to do simple code monkey tasks and that's it. gypsies which are the plebbiest of plebs and do nothing but steal, lie and destroy, originate from india. for a country with a population of that size there is very little innovation and productivity coming out of india.

Unless it was implemented in hardware, it would not execute in one cycle.

I was working on making a blog for myself, but seeing how that will take forever to actually start doing it, I don't really have anything I am working on right now senpai.
My question is why 4chan is being a botnet and censoring a whole bunch of words like
kek and senpai
>>51857989
The only reason why Haskell code was typically better than Java is because Haskell has less users.
>>51860790
Because hiroshima nagasaki is a massive kek and wants to sanitize the site so it's easier to sell everyone's data. Notice also how many, many on-topic threads and posts site-wide are being deleted, while pure shitposting is always allowed to stay up until the bump limit. This is another tactic to dilute the site.

>>51860790
Hiroshi arrived and the very next day decided he didn't like the mean words that people were saying.
>>51860822
Only on /b/, where they belong, and never site-wide. Moreover, moot kept bringing in more and more filters over the years because he's a double kek. Filters that initially autobanned you, often on false-positives.
>>51861201
they should censor "libertarian", "christian", "anarchist", "statist" and "capitalist"
also, "anime" and "trap"

But I'm not a christian. :^)

Hi everyone,
I want to make a bruteforce program in Python (for educational purposes, I'm trying it on my own files) that tries out different passkeys in an attempt to get access to an ecrypted TXT file which was issued by AxCrypt.
However, I cannot access the AxCrypt interface using command-line.

How can I make a program that automatically focuses the AxCrypt window and pastes in the passwords one by one?
