You should always multiply before diving with ints.
Still won't give you the accuracy of floating point, but if you plan on rounding later anyway then it's just as good.

int a = 3;
int b = 4;
int res;
res = (a / b) * 100;  /* If a < b, (a / b) will always evaluate to 0 */
res = (a * 100) / b;  /* Evaluates to 75 */

This method is used in old real-time embedded systems that lack hardware floating point support, because software fp is fucking slow as shit.

WITNESSED!

Can anyone recommend how I would read text from a running program into a script? For example if I type in notepad, the text will be picked up by my application.

I am not aware of any way to do this without first saving the data to a file. I mostly like to use c#/java in windows but i'm more interested in how the process itself is possible.

>>52577854
Why?

>>52577888
what you are looking for is called a keylogger.

>>52577888
You would need to modify the program to output the data somewhere as it's being typed.

That or like >>52577898 says, basically just read directly from the keyboard. That won't be specific to just one program though.

>>52577898
sounds more like reading out textfield widgets from a running application

SysExporter does that but unfortunately it's closed source

>>52577936
Either a keylogger straight up or a formgrabber, either way it's exploitative so not much POC is out there for the latter, you should be able to find shit keylogger sources pretty much everywhere online though.

>>52577898

I don't want to record keystrokes or anything, I mean to pick up the text periodically, like a backup kind of thing. If I open a text file i'd like my program to pick up all the text within the instance of notepad. Copy and paste it as a string pretty much.

Is this still considered keylogging?

>>52577965
Well, yes, if it is being done without notepad doing it. If that is the case, it's no different from a keylogger/malware.

>>52577965
if you have no target app it's pretty much keylogging, even though what you describe is much closer to form grabbing (input form grabbing to be precise) it's mostly use to steal info so as I said not much code to do this out there, unless you are targeting a specific application, in that case you can just read it's memory and hardcode the offsets to rad from and go from there.

>>52577965
that's very easy to do with pywinauto

In actuality, it's in C that you can't understand what the fuck is going on. Almost every non-trivial piece of C code is riddled with complex macros that use obtuse pointer tricks that rely heavily on packing rules and the like. I mean, just look at the list implementation in the linux kernel. Meanwhile in C++ everything is clear at first sight in all but the most obfuscated-on-purpose pieces of code.

Here's a question: what happens when the people who want to do everything in C++ always write obfuscated-on-purpose code?
You get people writing the fastest, most efficient bare metal shit in the world except it didn't really need to be like that, and now nobody else can maintain it.

I also mentioned two other languages that you ignored. If C triggers you that badly, you need to warn people in advance

It's not like somebody is going to read your code you fucking retard.

So, /dpt/, tell me about your obsession of reinventing the wheel
A bunch of threads ago, some retard even asked why asserts were shipped together with a language

What is it with this autistic "gotta do everything muhself!!!" attitude that most hobbyist coders seem to love so much?

>>52579098
I'm refering to shit like

#define container_of(ptr, type, member) ({                      \ 
        const typeof( ((type *)0)->member ) *__mptr = (ptr);    \ 
        (type *)( (char *)__mptr - offsetof(type,member) );}) 

#define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER)

Then you of course have a billion levels of indirection and since it's all macros you'll never be able to debug any error. For instance:

#define list_entry(ptr, type, member) \ 
        container_of(ptr, type, member)

Literally just a synonym.

Now of course, you can sit down and work out what the defines do (provided you have a lot of C experience). But when dogshit like this litters the entire codebase, you simply can't claim that things are easier to understand in C than C++.

>>52579215
didn't get involved in this asserts argument, but there's nothing wrong with programming of any sort in a daily programming thread

>>52579223
>#define container_of(ptr, type, member) ({ \

>>52579146
By definition, nobody writes obfuscated-on-purpose code if it's not to submit shit to a code obfuscation competition. Fuck off with your what-ifs. What if C was readable in practice? Well it fucking isn't.

Also I have seen plenty of obfuscated source. See the linux kernel for instance.
Most real obfuscated source is produced by a tool after writing legible code during development.

>>52579215
Because of people pulling shit like this: https://sourceware.org/bugzilla/show_bug.cgi?id=12518

You either use an existing library, but never update it so things don't break later down the line, and live with whatever bugs it has forever.
Or you make your own fork of the library.
Once you've made that jump, may as well just make the whole thing yourself.

>dependence on ""undefined"" behavior

Oh man, I chuckled sensibly. What a classic C technique.

>>52579247
So is your point that a language shouldn't allow it's users to do things in bizarre ways?
Because you can still do all of that, and more in C++.

That's kind of the point. The absolute worst C is never going to be as bad as the absolute worst C++ because of the extra dozen ways you can do everything.

We're not talking about existing code examples here, yes people have done terrible things with C. People have done terrible things with C++ too.
The point is, how much damage are you going to make it possible to make?

>>52579370
Instead you have a vast number of tools you misuse because they all suit different paradigms and workflows. Both languages compile to the same bytecode, C at least has more freedom and clear structure so you can make the macros that count, even if others abuse it to hell and back

>>52579370
>you have a shitload of tools at your disposal to achieve a goal without resorting to such hacks.

Unless everyone is well versed in the particular tools you decide to use, what makes you think that's any better?
If something is hard to understand, but at least consistent across the board then the people who know what they are doing can work it out at least.

If something is easy to understand, assuming you already know the entire language (one as large as C++) inside out, its not actually easy to understand.

>>52579375
My point is that a language should be powerful enough that the user doesn't need to use contrived hacks to circumvent its limitations. That's why I put a lot of weight on whether or not a language has a solid macro system (scheme, or common lisp in a pickle - NOT C), module system, generic programming facilities, static typing (inference, refinement, linearity, composability) when I consider using a language.

The least powerful a language is, the more hacks are needed to do basic constructs. The more powerful a language is, no matter how much you allow hacks, the less they'll appear.

};

offsetof(struct mystruct, reee) == 14

I was about to say that. It's long, but all the function names seem appropriate and descriptive, as are the variable names. It's not fantastic, but it's also not IOCCC-tier.

>>52579441
Not in the linux kernel :^)

>>52579411
Just because you've found a way to do something without abusing language semantics, doesn't mean anyone else would do it the same or be able to follow it as easily as you do.

Hacks are difficult for everyone to work through, including the author, but they'll tend to be quite similar.
Obscure language methods are difficult for everyone to understand, except the author, but they'll tend to be inconsistent with what most people associate to that language.

What's this fancy new Dapper Programming Thread?

I'm supposed to write a 'bare-bones' C++ function to translate strings to usable numbers. Is there anything glaringly wrong with this?

double pwr (double base, int exponent)
{
    double output = 1;
    
    if (exponent > 0) for (int counter = 0; counter < exponent; counter++) output *= base;
    else if (exponent < 0) return 1/pwr(base, -exponent);
    
    return output;
}

double stringToDouble (std::string input)
{
    double output = 0;
    int decPos;
    
    std::string::iterator decimalPositionIterator = std::find(input.begin(), input.end(), '.');
    decPos = decimalPositionIterator - input.begin();
    if (decimalPositionIterator != input.end()) input.erase(decimalPositionIterator);
    
    for (int counter = 0; counter < input.size(); counter++)
    output += (input[counter]-48)*pwr(10, decPos-counter-1);
    
    return output;
}

What stops one from writing a program to connect to many different proxies at the same time, and making them send a shit ton of HTTP requests to the target to open the connection, while not allowing the open connection to send any data back to you?

That's not up to you. If someone wants to send you packets, they are going to send you packets.
If you firewall off the proxies incoming connection you won't get any ACKs so good lucking forwarding more than a few bytes from any of them.

The short scale system is retarded.

>>52580133
>people still using the long scale system
Say it ain't so

>>52580133
Short and long scare are both retarded.

Long scale:
10^6 is million, and 10^9 is a milliard
10^12 is billion, and 10^15 is a billiard
10^18 is trillion, and 10^21 is a trilliard

So why the fuck is a milliard squared a trillion (10^18) and not a billiard?
Neither the short or long scale makes any fucking sense when they both skip other 10^3 like it doesn't exist.

>>52578562
Open a .cl file:

There's no such thing as a billard (kek) or a billion in long scale.

million = 1,000,000 ^ 1
billion = 1,000,000 ^ 2
trillion = 1,000,000 ^ 3

Short system:
million = 1,000 ^ 2
billion = 1,000 ^ 3
trillion = 1,000 ^ 4

It's the French system and French are always rights when it's about units.

>>52580283
Thanks for proving me right.

>>52580292
Billion and milliard are synonymous (milliard is the french word for billion). They don't exist at the same time.

can we go back to talking about programming?

Here is my new recommendation

million = thousand thousand
billion = million million
trillion = billion billion
quadrillion = trillion trillion

>>52580325
what nail polish maximises programming productivity?

I wish we did that, that really pleases my autism.

>>52580316
>Billion and milliard are synonymous
Not in the French system, which will be the norm, because French always impose their system to the world.

nobody even uses the terms for numbers after a trillion anyway, they use 10^x, so who cares?

>>52580351
Yes it is. Inform yourself. The value of a billion changes based on scale but the fact remains that milliard and billion are the translation of one another.

>>52580270
It's not my fault you can't read.
Yes, the problem is that the milli- prefix starts at 10^6 and not 10^3.

>>52580404
Writing a program to solve a problem you cant solve yourself is very hard.

A few friends and I wrote a program that turned your music into a death-metal Meshuggah mix. It worked by splitting the given song into 3 second increments, finding the most similar 3 second Meshuggah clip and laying it over. The results, while hilarious, were worse than having a human do the same.

>>52580374
Superior system:

one = 10 ^ 0
ten = 10 ^ 1
biten (hundred) = 10 ^ 2
triten (thousand) = 10 ^ 3
quadten (ten thousand) = 10 ^ 4
pentaten (hundred thousand) = 10 ^ 5
quinten (million) = 10 ^ 6
septen = 10 ^ 7

the short scale is easier to reason with. nitpicking about the names is what a sperg would do. the names still make sense if you start with a thousand and then add n*3 zeros after thousand

what comes after million? billion. what comes after billion? trillion. what comes after trillion? quadrillion. etc.

1 000
1 000 000
1 000 000 000

there isn't much to it. you specify what kind of character(s) to match and how many repetitions

\d     -> a single digit
\d?    -> zero or one digit
\d*    -> zero or more digits
\d+    -> one or more digits
(foo)? -> zero or one of "foo"

>>52580755
start by deciding the common data between the information you need to match and fill the parts that vary with groups like \d for digits, etc.

if you wanted to match a time like 12:34 or 16:01 it would be two digits, a colon and two digits, \d\d:\d\d

Your history knowledge is poor.

The Romans wanted to use 10 months, and named them March-December (some slight differences to today but mostly the same).
(There were two other months between December and and March, but they literally just didn't bother to name or number them).
Then they realised they didn't line up with the moon at all, and realised it was probably a good idea to name the other two.

They added them at the beginning and not the end because the name for April was tied to the spring season, so they had to fuck up the number based names instead.
Keep in mind these are the same people who had no numerical way to represent zero.

>>52581486
The majority of people don't say it the wrong way, they say it the right way.
That's why it's called the correct way.
This isn't subjective.

Most people say it without 'and', because there are a hell of a lot more Americans than there are Britons.

>>52581736
Plenty of Americans do, so it's perfectly valid. Languages aren't as static as you want then to be

No, they don't: http://english.stackexchange.com/questions/37958/how-do-you-correctly-say-large-numbers

There are more British English speakers across the globe than American English speakers.
Besides that, the shortened usage is only partial in the US, whereas the proper usage is prevalent everywhere else.
For once, this is not an occasion where the US has the biggest portion :^)

>>52581850
Plenty of Americans greet people with "¿Cómo estás?" or "What's good nigga" too.

Find some numbers that show more people use it your way and I'll stop correcting you.

You can say it's more intuitive, you can say it makes more sense, and you can say it's faster if you like.
Doesn't help the fact most people do not say it that way.

You misspelled "most"

>>52582048
It doesn't matter if more people say it, do you know how dialects work or are you just being retarded on purpose?

I don't have a problem with people saying things differently.
I have a problem with them saying things differently but thinking it's the norm.

It's well documented that usage in speech is changing, doesn't mean textbooks etc. have adapted just yet.
The funny thing is, I bet a fair chunk of those search are people hearing someone say "one hundred one" for the first time, and googling to make sure it's not just one guy who says it weird.

Because it IS the norm, as noted by the graphs.
