Actually that would mean the compiler can't compile itself, (Rust is self-hosted right?) because in order to detect politically incorrect vocabulary you have to include it.
And just in case you non-white autistic queer women were thinking of a really clever workaround to encode the words in such a way that the thought police mechanism doesn't detect it, remember that some straight white male might use it too, so you have to outsmart this technique with an even kluger technique, and so on.

If you define a variable twice. It'll just overwrite shit and again will not tell you what the fuck went wrong

The real problem is that people want to use toy examples to "prove" things. Higher level languages have more general constructs. People, say, shit on linked lists, because in their mind a linked list is just a sequence of simple values and pointers. But this is the most trivial linked list. A tree is a kind of linked list where the values aren't simple, but are lists themselves. And who would argue that trees are shitty? What's the real alternative for a tree?
And what about when the values are simple but different? For instance a list consisting of an enumeration, a string, and an arbitrary tail of integers. What if you have a sequence of unknown length of enumerations before the string? (Consider "the interpreter pattern" for a laugh.)
In (say) lisp the same representation is used for all these things. This can lead to optimization problems. But the cases where optimization is a problem are exactly the cases that aren't any easier in other languages with less-generic constructs. To make the lower-level code act the same you're going to end up doing the exact same thing the lisp runtime does, only probably less efficiently, hence greenspun's tenth.

Lisp has pairs of pointers and/or constants, not lists or trees.
>To make the lower-level code act the same you're going to end up doing the exact same thing the lisp runtime does, only probably less efficiently, hence greenspun's tenth.
This is a typical Lisp response i.e. pointer/constant pairs are "higher level" while abstract (implementation-independent) "heaps, queues, stacks, and hashmaps" are "lower level code" and "probably less efficiently."

>>51248652
You mean Qt?
>>51248572
The rules are basically this:
- Integer types have 'ranks' (char < short < int < long < long long), a lower ranked one is generally always converted to the higher ranking one (but not strictly always)
- Integer conversions try to be value conserving, if a signed integer type can contain all unsigned integer values (result type is a signed integer with higher rank, think unsigned short (16 bit) cast to signed long (64 bit) for example) the value is copied as-is.
- When the result type is unsigned it uses modular arithmetic (mod 2^n-1)
- If you have an unsigned value which cannot be represented in the signed type the behavior is implementation defined (depends on signed integer representation)
BUT for all practical purposes:
- Everything you will ever come across is two's complement, signed <-> unsigned are bit identical representations, casting from one to the other are no-ops.

It might sound funny now, but you might actually get good at some point, you might actually contribute a snippet of code to a commercial project forgetting it came from that old compiler and the project gets slammed with hefty license lawsuits

You are all professional god like programmers here how come none of you wrote any business applications to sell for a lot of money?
could anyone help me with extracting the second digit from a three digit number? here's what I have now, I need to extract every single digit#include <stdio.h>
int main(void) {
int n = 0;
int digits = 0;
printf("Insert a three digit number: ");
scanf("%d", &n);
int FirstDigit = n;
while(FirstDigit >= 10) {
FirstDigit /= 10;
}
int LastDigit = n % 10;
printf("%d %d\n", FirstDigit, LastDigit);
return 0;
}
yes this is a homework-related question

It is a sound advice in general, but here we aren't concerned about copypasting a free software snippet once, we are talking about constantly running your code through a free software compiler everyday. Kinda impossible to forget, dontcha think ?

Also, how are they going to know where the source came from if I never release it? Reverse engineer the binary? The entire premise just sounds silly to me. How does anyone prove anything when it comes to that?

number = 12356
digit = 3 (from right)
base = 10
number = floor(number / (base^digit)) = floor(1235 / (10^3)) = floor(12.356) = 12
number = number % base = 12 % 10 = 2

Ada is very modular, you can forget you are linking to an old library you made a long time ago. Seriously if you're at all serious about being a professional, don't fall into a license trap like that
>>51249828
scan the number to an array as a string. then you can just print out the chars.
>>51249064
it is encouraging something like an "immediate mode" which opengl ditched because it was stupid as fuck and no place in computer graphics other than the lowering entry level for opengl. not to mention it is java, so each opengl calls has another level of abstraction.
we were using it on my previous workplace, maybe it is libgdx or maybe it is mobile platforms but performance was shit. albeit harder to use, our ndk project was a lot better.
>>51249890
Code you write never 'becomes' any license other than whatever you choose to do with it.
GPL (or any other license really) only applies if you actually distribute something using someone else's code (for example a program containing some runtime library code)

this. libgdx might be decent if you're a beginner and just want something that works (but the magic fairies fuck you up and i think it's better to learn everything from the ground up) but you should really move on once you've gotten familiar with how game programming works
>>51250048
like what? Kind kind of software/games were you making?
>>51250020
You don't understand how Ada works, all modules in Ada have to compile independently of the rest of the project, this is enforced by the compiler. It's not like C/C++ where you can just add some header files to the project and no one knows about it
>>51250086
Games. I don't know if it is libgdx to blame but changing shaders was pretty slow for example.
Another thing I hated on libgdx was its gui library. it was unusable mess to work with different screen sizes. Is it still same? When you ditch gui stuff and you are worried that all those immediate opengl calls, libgdx adds nothing useful on top of jogl (it was using jogl right?)
At that point you are better just switching jogl or better move to native

>>51250123
You don't understand how licenses work.
It doesn't matter how 'a language works', what matters is what software is included in the thing you're distributing - if the program is linked against libraries written by someone else then you need to adhere to their license.
That's all there is to it.
The confusion comes from the fact that gcc implicitly statically links against something called libgcc which has things like intrinsic functions and various runtime support facilities, and since libgcc is GPL that would normally make the final executable covered by GPL as well, but this is why the gcc runtime library exception exists.

>>51250258
have you read it ?

nth digit = (number / pow(10, n - 1)) % 10

How are you going to copy paste a file into your project with an object file that you're never recompiling, and go on unharmed ? Especially if there is the RUNTIME SYSTEM of a language like Ada (position of ignorance from me) which is surely going to cause complaints since we're talking about it not even being the same compiler... You've lost, just admit it. Bravery is surrendering while it's still time.

>>51249890
The GPL virus has it that, in your case, if you compile some code with the GPL-infected GNAT gratis compiler, the object file that results is infected. But your source code isn't, and you're safe the second you change compilers. Not sure how much difference there is between these two compilers tho.
>>51250359
> damage control
What?
>How are you going to copy paste a file into your project with an object file that you're never recompiling, and go on unharmed ?
Non sequitur.
Again, I¨'ll make it simple for you:
does program.exe contain code other than what you wrote? If so, you need to consult whatever license that code uses, if it's GPL the act of distributing program.exe is considered a derivative work and *then* your code would need to be GPL.
If you never distribute program.exe or if it doesn't contain any statically linked GPL libs, then no license applies.
>>51250277
Then you can probably learn something from SICP
>>51250291
Yes
>>51250452
hardly
>>51250370
hmm it's just different notation you could have just told me thatcout >> "benis " >> i >> endl
>>51250478
I agree, but we are talking about unadvertently slipping some GPL code from GNAT gratis into a larger project, and that fact going unnoticed for so long that you get a lawsuit. Rerread thread

>>51250512
It's far more than different notation. After you've finished basic arithmetic, you're probably going to look into pointers next.
>>51250463
floor rounds down, if you're using ints you don't need this
>>51250562
no, they're const char*
>>51250522
So lets just ignore the fact that it's possible to link your project with precompiled libraries that were compiled in another compiler different from the one you're using

If you thought that then you're still an idiot, because even if that was the case your code wouldn't work.

it's better for your economy if your shitty 2D game doesn't run like ass on a $1000 smartphone
case SDLK_KP_PLUS:
while (Actors[focus].getInitiative() < 100){
Actors[focus].addSpeed();
if (focus >= player_count){
focus = 0;
}
else{
++focus;
}
}
Actors[focus].takeTurn();
break;
I'm committing a sin here. But I'm retarded. Somehow I'm going out of bounds and too stupid to see where.
takeTurn subtracts 40 from initiative.
addSpeed adds the speed value to initiative.
>iterate the actor list adding respective speeds to actor and loop back to 0 until someone's initiative is over 99. At which point remove 60 from that person's initiative.
It breaks on player count values of 1, 3 or 4, 7 or 8, 11 or 12, 15 or 16, etc etc. 3 more than the last and the next.
if speed = 11, or 10, it takes 7 turns to somehow reach actors[1] and for speed = 9, it takes 6 turns.
Apparently I lucked into using a good value until now.
