Reading the entire section on higher order functions in javascript made me want to vomit in my mouth a little bit.
Everything about higher order functions in JS is so fucking wasteful and yet the author goes on and on about how "beautiful" and "clean" it is.
I can't even read half the shit he wrote, passing function literals is not elegant.

Get raped and kill yourself, you retarded fucking faggot sack of shit with down syndrome.
I was working on a program to create DLC deck recipes for Tag Force Special. That project died a quick death.
Last night I started a little project for a simple renderer. I called it a night when I was too tired for simple vector calculations (how to find the viewport pixel world coordinates when given the eye point, another point the camera is looking at (defining view direction), distance of viewport from camera, viewport width and height in pixels and viewport width and height in object space).

>>54731579
Nope, no alternatives allowed and I wouldn't even know if there are any. The point is to learn how to use these programming environments since they're """industry standard""" (i.e. idiots who barely passed their shit can have something to click around in because coding is harrrrrd, then give up and let me rewrite their program in C or Python). At least in the previous semesters we were allowed to substitute GNU Octave for MATLAB.

Most of Java's operators where stolen from C, which didn't have a exponent operator because exponentiation couldn't be done on hardware in the 70s when C was made. It was implemented in software for the most part so it was just a function.

I have this functionvoid enter_breakpoint(unsigned long line_num) {
char buf[60];
strcpy(buf, "Entered breakpoint @ line #");
//strcat(buf, line_num);
strcat(buf, ". Press b to continue...");
send_debug_string(buf);
}
The call to this function is: enter_breakpoint(__LINE__);
I need to use these formats because they are what is provided.
void send_debug_string(char* string);
Only accepts char array. My attempts to convert this to a single char array has failed me. The above function basically takes in a string/char array and sends it to what ever serial is connected, it works and should be irrelevant.
//snprintf(buf, sizeof buf, "%s%lu%s", str1, str2, str3); - wont print to putty
//char vOut [11];

Yes I am a retard at C, and it's homework, this just isn't my usual thing.

Try reducing your problem and use snprintf to convert the ul to a char* and do string operations as in your current function. Then play around with cleaning it up if you so please

Had to make a few quick changes to get it to assemble. Namely, .L2 needs a colon after it, and the B LR and BEQ LR need to become BX and BXEQ respectively, or else the linker will look for a symbol with that name...
I made a C version of what I knew it was supposed to look like, and it produced a correct result. That is, this works:int multiply(int a, int b)
{
if (!a || !b) return 0;
if (b < 0) { a = -a; b = -b; }
int c = 0;
while (b > 1) {
if (b % 2) c += a;
a <<= 1;
b >>= 1;
}
return a + c;
}

This is literally impossible.
Good luck unrolling all your loops manually, faggot.
>>54732576
>I want to beat the compiler in producing optimal code [to multiply 2 integers]
Not gonna happen
>>54732597
There is one loop, and it is impossible to unroll for better optimization. But strictly speaking, I could reduce the code size by an instruction or two.
So, lately I finished my first actual program that was meant to be used (albeit for fun). I programmed it on OS X, for OS X. I used C and the SDL2 framework. It runs just fine on my system, but when I tried to give the binary to a friend of mine, it didn't work (he's obv. also running OS X).
So, my question is: How can I include the parts of the framework I need into the binary to be independent of it? Programming is pretty boring when your programs only work on your own system.
>>54732576
I looked at the code, and for a sec I thought I forgot what I did know about Assembly, since I only used it briefly, but I realized you're using a different type of Assembly, lol.
I only knew a little bit of basic MIPS x64 for a Comp Architecture class.
I've never seen those ARM commands before at all.
I wouldn't be able to help, then, sorry. =/
>>54732644
It probably has something to do with me not correctly understanding what flags certain instructions are modifying. The algorithm is right, the implementation is wrong. It's not worth expending too much time on though, as shift and add multiplication has no real world practical use... except maybe in multiplying arbitrary precision numbers - I don't know what they use for multiplying bignums.

>>54732775
That would be one way to do it, but it would be very inefficient. An 1024 bit integer might be implemented as an array of 32 32-bit integers (or 16 64-bit integers), and when adding is necessary, an add with carry instruction (or similar assembly mnemonic). Alternatively, a C programmer could check for overflow on addition and consider that a carry if necessary.

>>54732972
If you dont care about size you can just use void*. If you need the size you will need to write macros to either a) generate the required functions for the type, or b) use the macro as the function, but this would result in code duplication as you are effectively inlineing everything

I think I know why webdev faggots insist on writing backend and desktop apps in JS.
JS teaches some very nasty habits and it makes JS developers feel inadequate when they attempt to use C++, or even C, which have none of the cushy, wasteful features of JS, like the ability to return arrays as first class objects, anonymous function literals, and native closures.
So they stick with JS forever because they're literally too stupid to write those features in other languages without functional paradigms.

Not trying to discourage you, but you need to forget about your project for a while. A big project like that needs to be organised with some foresight, but you don't have that foresight yet. There's still a lot to learn, and I believe big projects are a shit way to learn new things (other than how to organise a big project).
If I were you I would start with some stuff that sounds ridiculously simple, but is actually quite difficult when you simply are not familiar how these things work. Write a simple function that reads wave function and then plays them. Add some controls, little by little. You'll notice that you will learn a lot of stuff and by the end of even that simple little program you know that you should have done the whole thing in an entirely different way. You don't want this for larger projects. For those you need to understand the details of the implementation well enough to plan it out before even writing a single line of code.
Of course, maybe in a while you can get back to the original plans, but for now you should stick with understanding parts of it. Putting it all together is harder than it sounds.

JS is great, a scheme gone mainstream. JS haters are C cuckolds that can't into higher order functions and the prototype chain.

JS syntax sucks.
I'm not a C cuck, but C++ damn sure has better... everything.
Too bad there's nothing like a "mobile C". I'd replace Java with that, too, if it was available.
Mobile C++ to replace Java
Web C++ to replace JavaScript and PHP
something to replace SQL that has more C-like syntax.
C/C++ is just too damn good. Ain't nothing cuck about it. It's just too feckin' good.

What's the best way to program in C/C++ on Windows?
>inb4 linux
I'd like to, but I need windows
I'm not really looking for a big IDE, just something lightweight and small which doesn't throw a billion different project specific files at me.
>>54735053
VM on top of windows using emacs
>>54734899
sql scrub here, what does 'collate XXXX' do?
>>54735053
MinGW, CMake and a text editor of your choice.
>>54735053
Code::Blocks is pretty good.
It's not really "small", but it definitely doesn't make a billion files.
It's also relatively easy to work with.
Only problem is it takes about a minute to load. If you use RAMDisk, you should probably put it in there. If you will use it a LOT, throw it in startup folder.
>>54735053
>on windows
>not using visual studio, literally the only redeeming quality of developing on windows
the fuck am i reading
if you are worried about bloat you can compile using the commandline and nmake anyways
>>54735069
It's basically just how it organizes the data.
Honestly, I didn't look heavily into it, I just wanted the character set with the most characters available. It's gonna be a social network, so I need to accept every humanly-imaginable character you can type into a computer.
utf8mb4 is like an extension of utf8, and utf8mb4_unicode_520_ci is a slightly updated character standard from utf8mb4_unicode_ci, so it handles more characters correctly.

he's asking about IDEs, any decent IDE should handle both C and C++

Just use any text editor with command line compiling if you don't want to use an IDE.
>>54734997
>>54735115
I guess you are only expecting like 10 users on your "social network" a flat table should work just fine then if you do not see an issue with making a text column your PK.

>I guess you are only expecting like 10 users on your "social network" a flat table should work just fine then if you do not see an issue with making a text column your PK.
Ok, fine, you know, I looked it up.
If it's gonna cause that much fragmentation, what should I do?
Just change that to unique and throw an otherwise meaningless numeric value PK into that table?
The other problem with that is that all the foreign keys relate to username.
Is your suggestion that I also change each and every one of those, too?
No, it's not for 10 people. It's supposed to grow and be an alternative to Facebook.
I wanted to avoid unnecessary locks on tables to search up user ID's.
The goal was to run it all in a single transaction.

Do you guys still stick to the 80 column rule?
I'm trying to become a more disciplined programmer as I'm a bit of a messy hackjob atm.
Any other good practises worth recommending?
>>54735709

Fuck no, it's constraining and impractical.

Not really, we're no longer working in 80x22 terminals so there's no reason to.
>>54735709
>Do you guys still stick to the 80 column rule?
I try to keep it under 80, but I only set a hard limit at 100.
>>54735709
>>54735752
>>54735764

How is that not useful?
There are a couple of macros to implement the machinery, but you can use it for as many functions as you want.

How will one go about splitting a quantity on non equal parts but the resulting parts while random much be within a certain amount of the of the amount the part will have been if split evenly?

Say I have to split 100 in ten parts.
Evenly I get 10x10.
The way I want to calculate it you get
12,8,9,11,10,12,12,8,8,10 = 100
I want a formula that gives random splits within a certain range of 10.

kys retarded webshit sperg trap cmen cshart hasklel
>>54736364
I don't get it. Explain further if you please.
>>54736451
There's lots of solutions to your problem. The first step would be to figure out what you want the range of numbers to be.
>>54736451
arr = array of ten integers
for i = 0 to 5
take a number in range 1-19 and put it in arr[i]
for i = 6 to 10
take the result in arr[i-5] and subtract it from 20; put the result in arr[i]
shuffle arr for good measure.
>>54736451
20-x=y => x+y=20
5x20=100
>>54736514
ok say 100 in ten parts split randomly but within a range of 2 from 10 so [8,12].
>>54736526
It works beacuse the pairs arr[i] + arr[i+5] will all sum to 20, so the total will sum to 100.
>>54736536
in that case you do
>>54736364
in range of 8-12 instead of 1-19
>>54736536
Same as >>54736514 but take a random number in range [8, 12] in the first loop.
>>54736526
Oh and I made an abvious error with array indexes in the first loop
