I'm going to assume the answer is "no" but:

In C# I can use reflection to refer to any class file that exists in the solution. So if I have 20 class files called "Problem_XX" I can use reflection to dynamically call those files overloaded functions without having to hardcode anything.
e.g. Problem_01 and Problem_02 and etc have a method called Run() and I can just use reflection to take an input of, say, 02, to find and run Problem_02.Run()

I ASSUME there's no similar way to do this in C?
The reason I want to is so I don't have to constantly update and hardcore a driver file when writing exercise problems.

man's C syntax gets awful when you get into the lower level stuff, example i found on the internet:
>#define DEV_REG (*(unsigned char *)0x80000000)
what the fuck is this shit

>>59962875
t. butt boy

what's the most elegant way to assign str1 to the longest string of two strings, and str2 to the shortest string of two strings in python?

>>59962873
it's simple as fuck, you brainlet. it's a hardcoded memory address that probably has some significance on the target platform, being cast to an "unsigned char*" so that it can be dereferenced, and thus used (almost) as a normal variable.

>>59962875
I don't even know what this means

>>59962896

>>59962885

>>59962907
sorry bb ily

>>59962897
I'm saying you're a butt boy.

>>59962873
fucking idiot
stick to python

>>59962895
and before you say it, doing a = min([str1, str2], key = len), b = max(.. wouldn't be reliable since the strings could be of the same length. i thought of that too

>>59962895

str1,str2 = sorted([str1, str2], key=len)

Python isn't a language, it's a torture device.

>>59962924
Prove it.

>>59962873
>>59962880
It's worse when the header file just references another file and provides a macro/wrapper around another library function in another file and you have to go like 3 layers deep into the darkest depths of the library that was never intended to be read by mortals to find the actual source code of the function.

Example: http://blog.hostilefork.com/where-printf-rubber-meets-road/

Am I a shit programmer if I can't find the motivation to program very often

>>59962946

only if you will mention to your teach that you got help on at 4chan.org/g/dpt

>>59962926
thanks lad. how do you guys learn syntax like this? just from reading books on the language you're learning? i liked haskell because you could do a lot of really elegant things like this without having to memorize quirks. is python just one of those languages with a bunch of hidden features you gotta memorize?

>>59962965
Well I used to do some golfing code challenges in Python for a little while, learned some cool tricks there (I could share some). And I like to write Haskell for fun, because it's pretty much constant golf.
Destructuring syntax is invaluable (even though it fucking sucks compared to actual pattern matching). And sorting a list using len() as the key is the most "clever" solution to your problem.

>>59962873
It literally just means "define DEV_REG as the unsigned byte located at memory address 0x80000000". That's nothing compared to function pointer syntax.

>>59962953
>pointers are hard :-(

A while back I wrote my own vectorN implementation with simd instructions and the whole everything. I was well underway into writing a generic matrix type when I found that there's a fucking library called GLM that does all that shit already.
Goddamnit /g/, why didn't you tell me!?

>>59963056
*Rust

>>59963094
*Nim

>>59963056

C++ would use the same macro. Unless you wanted to define some struct with an overloaded = operator to wrap around the behavior of dereferencing that address, but that's... overkill.

I made a C# class with 11 inner classes that works perfectly. Should I just ignore everyone who tells me not to have inner classes?

>>59962626
>new

>>59963109
*Haskell

>>59963124
No, it would have a nice RAII type to allocate and deallocate the device memory in the first place with an overloaded dereference operator so you don't need to hardcode memory addresses.

>>59963167
The memory address is hardcoded because there's a specific hardware device mapped to that address. And allocation/deallocation is pointless if you're working with literal memory addresses.

>>59962712
AFAIK there isn't a PORTABLE way to do this, but you can do it. I assume you're using windows, right? You'd have to compile Problem_01, etc as dll files and load them.

>>59962532
Whenever I try to run the program it stops at the 3rd calculation and shits itself "bin.exe stopped working"...why?

    x+=y*z;
    printf("%d\n",x);
        x-=y+z;
        printf("%d\n",x);
            x*=y-z;
            printf("%d\n",x);
        x/=(y/z);
        printf("%d\n",x);
    x%=(y%z);

>>59963198
Do you even know how device memory works? You need to get the base address from the PCI registers and then remap it into linear address space. Nobody in their right mind would hardcode that shit. You can't assume anything about the memory layout at runtime.

I'm working on a very basic interpreter

#include <iostream>
#include <string.h>
#include <stdlib.h>
#include <windows.h>

using namespace std;

int main(void)
{
    string command, aux;
    system("CLS");
    cout << "                                                          4chan\n                                                         " << endl;
    do
    {
        cout << ":::~ ";
        getline (cin, command);
        cout << "The command is " << command << endl;
        string aux(strstr(command.c_str(), "help"));
        if (aux)    
            cout << "Help was found";
    } while (command != "exit");
}

I'm using strstr to find if "help" is in the string, so if it is then it will print "Help was found". What I want to learn from this is how to use conditionals with strings so I can make more complex functions like asking for an area of an specific shape.

The problem is that I can't compile it because g++ says it can't convert string aux to 'bool'.

>>59963314

Why yes, and how do you suppose you would read from those PCI registers... perhaps via a hard coded physical memory address, such as... oh I don't know, 0x80000000?

http://wiki.osdev.org/PCI#Configuration_Space_Access_Mechanism_.231

>>59963453
Did you even read what you just linked? 0x80000000 is not a memory address related to the PCI configuration space.

feels comfy man, gotta keep focused on this cracking the coding interview in python tho, no C until i finish this

>>59963476

It is used in generating it.

/* create configuration address as per Figure 1 */
address = (uint32_t)((lbus << 16) | (lslot << 11) |
          (lfunc << 8) | (offset & 0xfc) | ((uint32_t)0x80000000));

>>59963529
That's just a single bit that needs to be set to enable port 0xCFC.
Not a memory address.

>>59963552
i hope you get banned for low quality posts

>>59963133

It's your code so the choice it up to you. But i would seperate the classes out, as a class should only have one responsiblity and ant change to the class should change its responsibility (S in SOLID). Also, you may end up using portions of the inner classes in different areas of the application, so seperating them out will reduce duplications.

>>59963550

It's a base address. While the macro was pretty poor if it was trying to interface PCI, you cannot get around the fact that there will be some hard coded magic numbers in dealing with DMA.

You're dividing by zero.

i want to make a bot that trawls pictures with certain keywords on twitter and detects whether or not there is a face in the picture. Is this doable for a noob?

>>59963746
It's literally a single bit that enables a subsequent access to port 0xCFC. Calling it an "address" is a misnomer, but crappy code on osdev.net is nothing new. In any case, it doesn't have anything to do with an unsigned char pointer to memory address 0x80000000 which is what the macro referenced.
Just about the only things you can make any assumptions about (and hardcode) when dealing with PCI are the address space ports 0xCF8 and 0xCFC.
Also we didn't quite get to DMA just yet.

programmers in organisations spend their entire life trying to get through, organisationally, to do something meaningful
in vast, dysfunctional organisations such as microsoft, the huge number of programmers are there to provide extensions of functionality fast, where it is required

it isn't a job where anyone gets to design anything complete

programmers are like termintes (now) .. but they are required to build little bits, in a very restricted way. original conceivers had the opportunity to design something larger, more sustainable, progressive, but we are stuck with a dysfunctional termite heap that nobody understands

No. It depends on the number of assembly instructions used and what assembly instructions are used. E.g. division instructions eat about 100 clock cycles while assignment statements take about 1 clock cycle. It also depends on the locality of your program.

2 things:
1:
If the relationship between character and bag is 1:1 then bag doesn't need its own id - it can use character id.

2:
since 1 bag contains many items, item needs a foreign key to bag. bag shouldn't contain a foreign key to item.

I have two C programs (let's say A and B) running on a Linux machine. Program A needs to send a command with parameters to program B from time to time and subsequently receive a return value.

What is the best way to achieve this?

Using a socket seems like an overkill.

>const int& right

This isn't right.

>>59966018
Are programs A and B proven to be running at the same time? What if one of them loops or halts unexpectedly?

>>59966018
There are so many ways to do IPC. Using a socket/pipe/whatever would probably be the easiest way.
However, if B doesn't need to be running constantly, you could just have A run B itself every time it needs to, and communicate with it using its arguments and stdin/stdout.

Trying to install pyperclip, the most recent version is for 3.5. How would it go installing it on 3.6?

>>59967350
What have you tried? There are few backward-incompatible changes between 3.5 and 3.6 so there must be a way. I just installed it with my package manager on ArchLinux and it seems to import fine under 3.6.0....

>>59967298
I'm writing a C library that's basically a big collection of generic data structures (void* data and key types) and I can tell you the only advantage they have is that you can scan the list backwards.

And that's only IF, in your implementation, you store the head and tail pointers. If you manipulate your list just by storing the head pointer, then they are worthless and offer no advantage whatsoever. In fact you waste space by storing a pointer to the previous node.

Circular doubly linked lists though are the fastest to insert/append elements to (these operations are O(1) at worst case), even if you don't store both the head and tail pointers (just with storing the head pointer).

An example of compile-time computation, although you could hardly call it such, considering this implies you only need to compute something once, is any algorithm which makes use of primes.

>>59967700
What format is the string? What language? Have you RTFM on your specific language and library and thought about it?

Two possible paths:
- either the string specifies a timezone and you can use that information to pinpoint the instant in UTC, for example
"Wed Apr 19 13:47:38 CEST 2017"
I happen to be in Switzerland and we have Central European Summer Time right now. With the appropriate function you can parse this into a locale independent timestamp.
- or it doesn't and it supposes you know it by context, in which case you have to pass "CEST" or something to some function so it can meaningfully interpret the string.

>>59967778
Strings are in this format: "19/04/2017 08:50" (dd/mm/yy) I just separated month, day etc using regex
I was recommended the "moment" library not long ago, this is how I was using it

let date_new_test = self.moment.utc();
date_new_test.tz('America/Toronto');
date_new_test.date(day);
date_new_test.month((month - 1));
date_new_test.year(year);
date_new_test.hour(hour);
date_new_test.minute(minute);
date_new_test.second(0);
date_new_test.millisecond(0);
date_new_test = Number(post_date_new.format('x'));

It's nodeJS as I've said, the last bit ".format('x')" just returns the unix time which is what I store. What it does wrong is that it gives different unix times, for instance while I'm testing it locally on my machine it will give number x while in production (hosted in switzerland) it will give number y. Shouldn't it give the same unix numbers on both since I'm already setting the same timezone for both and both will be parsing the same string? it just makes no sense to me

typing quotes from a book creates an inflated wpm because you can read the words and jam them out non-realtime (i.e. taking a gander before starting)

Should I waste my life on IT and learning how to programm if quantum computers will destroy everything soon? Codemonkeys will lose their jobs, information security and cryptograhy sphere is goint to be destroyed. Scary.

You wouldn't bother to learn how to program even if quantum computers weren't going to be a thing, stop kidding yourself.

>>59967971
You quoted the wrong guy, how should I set it up then?

>>59968234
Excuses anon. It doesn't matter for most of us because we will need to program quantum computers too. Unless they're too unworkable which makes classical computing still relevant.

Trash.

>be me
>at interview
>get asked how to check if a string is an integer or float
>go on whiteboard
>write method that searches for a dot in a string (that way he know it was a float)
>never heard from them again

is there a better way to do this?

>>59968496
Made you a function :^)

def add(a, b):
    print((str(a)+"+"+str(b)+"={}".format(int(a)|int(b))))

I'm trying to build an app or a program but I don't know what to do now:
the goal is to build a simple website with dashboard on my localhost (got front-end part down, no problem here)
now I want to write a script (I guess php) that downloads emails from my gmail and shows ones with chosen email subject (i.e. work)
I made google api quickstart, put it on localhost
now what shoud I do?
I want simple script that returns php variable with email with mentioned mail subject. rest I can do on my own
I also tried using imap but it doesn't work
I know some coding, simple programs but never did more complex project than simple php cms

wew lads

Can anyone resurrect /wdg/

Cause im cool, pic related to show it works :p

>>59968668
I have to try this, memesnek is unreal

>>59968668

add = lambda a,b: print("%s+%s=%s")%(a,b,int(a)|int(b))

>4|20=20

>>59968687
What's unreal about it? Did you seriously take that bait?

>>59968649
>be black
>write a red black tree
Wow, racist.

>>59968760
>>be black
no thanks

>>59968623
yes, certainly, 2 is an int and not the float of 2

perhaps learn more basic skills in c before trying to advance
or was it python? haha

Everything about Python is unreal, the fact that this could even work is plausible and therefore innately hilarious.

>>59968623
pssssh, I got methods for this for DAYS

static (int?, float?) IsIntegerOrFloat(string input) => int.TryParse(input, out var intValue) ? (intValue, null) : float.TryParse(input, out var floatValue) ? ((int?)null, (float?)floatValue) : (null, null);

>>59968786
It also works in C :^).

The website you're browsing right now is impossible without IO.

>>59968795
i was supposed to do this is C, but thanks anyways

You are responding to a bit of a joke.

I mean, it technically works in a way, but that is NOT the way you'd really go about doing things.
