old thread: >>54358814
What are you working on, /g/?
I would really appreciate if anyone could answer my quick question please.
Using Selection Sort to sort an array of integers 1, 3, 8, 4, 2, 5, why is the number of comparisons required 15 and not 20? I need to scan the whole array once to show that 1 is the smallest, and then 3 more times for 3 other swaps, right? So why is it 15?

he's using a style from C where you declare all your variables at the top of the function so people can easily figure out how much memory the function will use. its useful but somewhat outdated. you can take that line out and change the below codeboolean foundNumber = checkGuess(...)

In c++ how should I declare global functions whos header is included in multiple source files?
so here i am /dpt/, getting ready to get into GUI and Game making with C++.
So what are good stuff i need to read to get into those. The thingi want to learn from game programming is jsut the general train of thoughts that go into making them.
i picture i should go about them this way.
i make a core that holds all the data types, with a layer with all the functions that will apply on them as well as general functions to the general flow of the program, then for a gui software, a layer with all the GUI elements, connected to the inner layer's functions with the general flow dictated in this layer.
should go the same for game making.
any help would be good on this shit.
also i guess i'll getting into Qt now, right?
what else should i go for to study the general way GUI components should work, or the various ways you can connect them together or whatever. same for gaming.
>>54363942
oh he wants you to define checkGuess and getNumber.
>>54363955
write it in a header file, include the header file in your source files
>>54363955

}
Then include the header wherever you need to use the function.
>>54363955
you should define the functions :int getNumber(10){
//generate a random number beteween 1 and 10
}
boolean checkGuess(randomNumber, userGuess){
//compare these two values and return true if equal, false otherwise.
}

exact width integer types are optional in c99
>>54365417
uint32_t is not guaranteed for all implementations of C99 and C11. Where none of the standard types are 32 bits in size, uint32_t can't be used. It is preferred by some to use uint_least32_t for types that don't need to fit exactly 32 bits, but need to be at least 32 bits and as small as possible.
>>54365352
good work anon
a couple exercises:
1. make a program that prints all permutations of a string
so, if you enter the word like "dog", it will print "dgo", "gdo", "god", "ogd", "odg"
2. write a program that prints the prime factorization for a number (less than, say, 100)
so if you enter 45 it will print 3^2 * 5^1
>>54365567
>>54365575
Should anyone really care though? I get the whole autism here, but it's not an actual relevant problem, come on. I use int*_t because it's short and I see exactly what I get.
>>54365301
When I write software, it should work on most but not all systems.
However, for the systems on which it does work (virtually all consumer personal computers), it must work exactly how I desire.
This means exact width types.
>>54365648
or you could not write shit code. I bet you're one of those programmers who thinks they need to know the byte order of their system to write portable network code.
>>54364881
What in the world is bitwise iteration?
This is the new rotational velocidensity.
>>54365648
do you also make sure this is true?sizeof(char) == sizeof(short) == sizeof(int) == sizeof(long)
because there are real systems that guarantee this
>>54365675
Well no, in C (both unix and winsock) you have htons and friends, in C++ asio will do it.
What is your point?
>>54365648
When you use [u]intN_t, you're making the claim that this type is that exact length for a specific reason. You should question whether that type NEEDS to be N bits, or if it only needs to be at least N bits.
For example, if you want something to be at least 32 bits portably, use long or [u]int_leastN_t. There is no point fixing a type to exactly 32 bits, just because it MIGHT overflow 16 bits.
The only situation I can think of where you really need exact width integer types is when you're dealing with binary files where you need to read values that are an exact size.
>>54365803
Oh.
>>54365680

>>54365615
For pretty much all relevant platforms, you don't need to care. Tru64 UNIX on an Alpha machine doesn't support 32 bit types, but chances are high that the code that you're writing won't be run on one.
>>54365962

Does a video contains more bytes if it has a fat person recorded in it?
>>54366105
Nope std::string does not have operator+(int). Your example will not compile.
>>54366210
okay, good
Finally hacked a playlist onto my music player.
>>54366191
since the less pixels change in a video between frames, the more it can be compressed; and taking into consideration that fat people could potentially fill more pixels of a frame and are less likely to move than average people; i'm gonna say no, it potentially can be compressed to be smaller in bytes than the same length video of an average size person.

however: a static background is kinda the best compressed chunk of a video, and a fat person though hardly ever in motion, can cover up a sizable static background. certainly more than an average size person.

I was telling you that you have to be 18 to post here, not guessing that you are 18 years old
>>54366362
The type of a string literal in C++ is defined by standard to be const char*. Adding an integer to that is just basic pointer arithmetic.
>>54366362
>You don't know that a String is a pointerconst char *str2 = &(str1[250]);

For that assignment to be valid, string MUST be a pointer, unless there is some silly Meme++ nonsense going on in the background that I don't know about.

Yep, well I'm not depressed or anything, but I'm also a student with a job in the field so the fact that I've only ever made small personal projects isn't a depressing idea. Perhaps contribute to FOSS?

>>54366506
Logical OR is short circuiting.
>>54366473
"Kek

"
>>54366533
the || ones will always print
the && ones will only print if neither of them is 0
>>54366476
Yep. But you just have to keep pushing yourself. Always make new goals. Try new shit, find things you want to make, attempt them when you have the time... and have fun even if what you make is just a toy.
>>54366533
if the first operand of && is false, it doesn't check the second one, because it already knows the entire statement evals to false
>>54366480
>Nope
You should. I like the minimalism of it. Do it up nice and polished and you might find a lot of people appreciating it.
>>54366556
>>54366569
Right, I understand logic operators
I don't understand how puts() is "true" or how 1 or 0 are true/false, nor do I understand how those are interpreted as statements rather than the conditions to check before executing a following statement.
How is the command (puts()) also one of the conditions?

>1 || puts("Top\n");
Here, the compiler knows the entire statement is true after it checks the 1. My compiler doesn't print Top here, but yours might.
>0 || puts("Kek\n");
It checks the 0. 0 is false, so it checks the second operand, puts("Kek\n");. To check an operand, it has to evaluate it. So it evaluates puts("Kek\n"); by running it, like anything else.
>1 && puts("M8\n");
For && to be true, both conds have to be true, and since it knows the first one is true, it checks (runs, then checks the result) of the second one.
>0 && puts("Fag\n");
Since for && to be true, they both have to be true. If 0 isn't true, there's no use in running and checking the second operand, since we already know the statement evaluates to false
>>54366601
I have some software written in C# that i'm adding copy protection too. Basically verifies with a server that it's not copied. I figure if i sell enough copies for someone to bother cracking it i'll be in good form anyways. Could rewrite the whole activation system then with something more crack proof.
>>54366596
C needs to evaluate any statement on either side of || so it can return a value.
and C considers anything except 0 to be true. not just 1.
maybe you need to study some compilers.
also this guy is right >>54366548
it will short circuit. the actual output is as he said
>>54366648
>So it evaluates puts("Kek\n"); by running it,
this feels very obvious now and i feel dumb
>>54366674
it's okay, you are dumb
>>54366682
>>54366665
look - as long as you don't have the fucking key generation methods HARDCODED INTO THE FUCKING SOFTWARE ITSELF, you should be ok.

>>54366771
They're divinely random
>>54366814
No.
>>54366710
wow, yeh i don't do that. It checks with a server to verify the activation code. But if you decompile it, you can just change the verify activation method to always succeed.

Maybe one day. Summer is coming up so I'll have some free time.

; rax contains 0x1

; rdx now contains 0x7
Can anyone explain why? Self-teaching Assembly
You have a stack of n sheets of paper, each with a date and time written on them. You need to sort them by date. Your memory isn't perfect, and whether you divide things up into piles, or mark it with sticky notes, you can only remember the position and date of k different sheets of paper. Your ability to eternal positions also isn't perfect, so inserting a piece of paper or pile of papers into another pile of papers at an arbitrary position i is impossible, although if the papers are sorted or marked in order, you can take log n time to find position i.
What is the ideal sorting method for this situation, and what is its time complexity?
>tfw you have an idea that sounds brilliant but the algorithm is so simple that its almost certainly already been done

HOW YOU DO THIS
>>54367084
Typed "x86 div" into google and found a page that says this:
>Unsigned divide EDX:EAX by r/m32, with result stored in EAX = Quotient, EDX = Remainder.
So probably there is some weird shit in rdx before the instruction.
>>54367084
What does rdx contain before you go into that instruction? It plays a part in it too.
rdx:rax / arg, where : is concatenation and the result stored in rax and the remainder in rdx.
>>54367160
you can do this stuff with pretty much any 2D graphics library.
>>54367115
post it
>>54367171
>>54367187
I completely forgot to zero out rdx
That explains a lot
>>54367160

mov r12,0xA
mov rdx,0

Now that wasn't so hard.
You're on x86_64 right?
>>54367201
How are those figures called? (The line ones)
>>54367265
Ye, I making a FizzBuzz, and goddamn was it a pain
pastebin.com/XyXvpVCD
>>54367205
It's an algorithm for generating recipes by cross -referencing a database full of ingredients with whatever shit you have in your fridge and pantry.
The database stores ingredient pairs prioritized by compatibility, ingredient information, and generic recipe information (for example, a burger has buns, ground meat or meat substitutes, 0-4 vegetables, 0-2 cured meats, 0-1 eggs, 0-2 sauces, 0-2 cheeses)
>>54367320
no idea. Reminds me of the mystify screensaver windows used to have https://www.youtube.com/watch?v=p-howMhFecQ
>>54367265
>mov rdx,0
You can also use the 'cqo' (convert quadword to octoword) to sign extend rax into rdx.global _start
_start:
mov r12, 3
mov rax, 10
cqo
div r12
mov rdi, rax
mov rax, 60

What are the benefits to learning assembly?
>>54367581
you can do embedded systems shit and that's about it
>>54367581
It helps you understand how higher level programs are implemented.
>>54367617
>programs
programming languages*
What the hell is overloads in Visual Studio? I been crawling all over Stack Overflow and can't figure it out.
>>54367201
is their an easy "plug n play" one with a "drawLine" function
>>54367718
yes, pretty much all of them. 2D canvas in html 5 for one.
>>54367727
There's also cairo, skia, GDI, Direct2D and a shitzillion others.
>>54367718
You wouldn't even consider it a plug n play library just because it has a draw line function, that's pretty essential to all graphics libs, idk about really lowe level stuf though like opengl (probably not) or whatever the actual library is called
Work smart not hard, right?
And by that I mean give up on trying to make a custom user control and instead use a ListView in "List" mode so it works like a ListBox.
Fuck you Microsoft.
>>54363185static int Product(int a, int b) {
if (a == 0 || b == 0) return 0;
else return a + (Product(a,b-1));
}
>>54367828
even opengl can practically do it.
it's more likegl.begin();
gl.drawVertex(Vector3(0.0,0.0,0.0));
gl.drawVertex(Vector3(0.0,1.0,0.0));
gl.end();
gl.flush();
or some shit but it's not far off.

That's what you get for sticking with winforms. WinForms sucks shit for any kind of UI that's not a gray enterprise data entry form.
Learn some WPF.
I am retarded. My method ends before finishing.public static void searchList(ArrayList<Integer> list){
Scanner in = new Scanner(System.in);
System.out.print("What number would you like to search for?: ");
int num = in.nextInt();
for(int i = 0; i < list.size()-1; i++){
if (list.get(i) == num){
System.out.println(num + " was found in the list.");
}
if (i == (list.size() - 1)){
System.out.println(num + " was not found in the list.");
}
}
}
>>54368024
>Learn some WPF.
WPF is scary! In any case, the listview works perfectly.
Maybe I'll do my music player rewrite in WPF so I can actually learn it.
>>54368072
>WPF is scary!
It's not that bad. It's not a ton of extra shit you can ignore. Otherwise it's just like WinForms. The main difference is xaml. Which is basically nothing more that an intermediate step between code genning your WYSIWYG to C# as WinForms does. It's a lot fucking nicer that that dirty designer.cs bullshit WinForms does.
>>54368115
>It's a lot fucking nicer that that dirty designer.cs bullshit WinForms does.
Don't shit talk muh partial classes, m8.
>>54368138
partial classes are one of the ugliest parts of C#. It wouldn't surprise me at all if they existed only for the sake of WinForms. I've never seen a good reason to use them otherwise.
Why don't people use cython again? It's just python cross-compiled to C code
>>54368170
Why not just write in C?
