What are the ways you would "kill" portability?
>Platform dependent libraries
>Usage of specific compiler features
>Calling particular shells
>Creating objects with filenames that contain special characters
>Make unique syscalls to allocate memory in certain ways
Now I need some really smart ways.

>>60421357
Obfuscate some code which detects the platform and crashes the program or just introduces major bugs.

>>60421357
Rely on the behaviour of malloc(0).

>>60421697
Allocating a pointer to a memory block of size 0 guarantees a pointer that can be safely free'd, preventing you from having to do stupid shit like

free((!ptr) ? NULL : ptr);

>>60421745
I know. You can still add other (probably pointless) NULL checks, that makes the code only fail on some implementations.

>>60421745
if ptr is null, why can't you just pass that to free?
it's a dangling unallocated pointer you need to worry about

>>60421803
His point is that you CAN pass the NULL pointer into free safely.
free(NULL) is explicitly defined to do nothing.

>>60421563
What makes you think he uses it?

Now that the dust has settled can we all agree that Fortran is the best language for scientific computing?

Looking for a book or resource to learn C#.

I already know Java fairly well, which should help; as well as a glut of other languages. Just want something structured for a non-novice so I'm not guessing, looking at the documentation every 5 minutes, and writing non-idiomatic code.

I'm trying to roll my own copy constructor / assignment operator for a doubly-linked list in C++

right now my code looks something like this:

// where rhs is the right-hand argument list
if (rhs.head == nullptr)
        {
            head = tail = nullptr;
            count = 0;
        }
        else
        {
            head = new Node(rhs.head->data);
            Node* lprev = head;
            Node* lcurrent = head;
            Node* rcurrent = rhs.head->next;
            while (rcurrent != nullptr)
            {
                lcurrent->next = new Node(rcurrent->data);
                lcurrent = lcurrent->next;
                rcurrent = rcurrent->next;
                lcurrent->prev = lprev;
                lprev = lprev->next;
            }
            count = rhs.count;

I'm getting null-pointer exceptions with this, but I'm not seeing exactly where I fucked up, or how I could fix it.

>>60422447
Nevermind, I think I figured it out.

if (rhs.head == nullptr)
        {
            head = tail = nullptr;
            count = 0;
        }
        else
        {
            head = new Node(rhs.head->data);
            Node* lprev = head;
            Node* lcurrent = head;
            Node* rcurrent = rhs.head->next;
            while (rcurrent != nullptr)
            {
                lcurrent->next = new Node(rcurrent->data);
                lcurrent = lcurrent->next;
                tail = lcurrent;
                rcurrent = rcurrent->next;
                lcurrent->prev = lprev;
                lprev = lprev->next;
            }
            count = rhs.count;
}

Is there an open source license which will repel GNU niggers from my software?

>>60422566
FreeBSD

>>60421332
I am doing my homework.
This time, I have a Textfile that I should read.
So far so good, java can read it.
Now I am tasked with displaying the greatest integer in a Textfile
and quite honestly?
I am stumped.

What I thought about is the following:

Open file
While the file has numbers, compare one number with another, if the first number has a greater value than b, then keep a and assign b another integer.
If b is greter than a, then let a be assigned the value of b and let b take the value of the next integer.
if there are no numbers available anymore, let the biggest number be assigned to the variable max.
So far so good, but the integers a and b are defined inside the while loop.
and they are always reset to zero.
What is the problem here?

>>60422611
Open file
Store all numbers on in a array
Spit out the maximum number on the array

>>60422579
I have seen some of them use BSD-licensed software.

You don't need arrays to solve this.

>>60422779
The discord is counterintuitive to programming, you don't wanna join senpai.

I've got my renderer working with some matrices but the coordinates are in "clip space" I think? They go from -1 to 1, I'd like to be able to have them in pixel coordinates and then just use some matrix to convert them but have no idea how to even begin to do that.

My orthographic matrix does this just fine but as soon as I try the with perspective matrix is changes.

It looks like shit, but C++17 is starting to approach Lisp in power. I'm using Lisp-style fexprs to build an embedded DSL that compiles into byte code. Byte code for what? A parsing machine for Parsing Expression Grammars. In only a few hundred lines of code.

Might try rewriting it with the Concepts Light implementation floating around after, see how it improves it.

Yeah, it looks like shit, but the resulting DSL is pretty clean compared to the underlying infrastructure. This fragment of a calculator grammar as an example is pretty close to what you would expect for an external PEG DSL to look like, and I've even got support for attributes.

long long variables[26];
long long e, l, n, r, s;
int i;

rule SPACE  = *" \t"_ts;
rule EOL    = "\n"_ts | "\r\n" | "\r" | ";";

rule NUMBER = +"[0-9]"_ts >= SPACE <= [](auto x) { return std::stoll(x); };
rule ID     = "[a-z]"_ts >= SPACE <= [](auto x) -> int { return x[0] - 'a'; };

rule ASSIGN = "=" > SPACE;
rule PLUS   = "+" > SPACE;
rule MINUS  = "-" > SPACE;
rule TIMES  = "*" > SPACE;
rule DIVIDE = "/" > SPACE;
rule OPEN   = "(" > SPACE;
rule CLOSE  = ")" > SPACE;

rule Value =
    n%NUMBER                < [&]() { return n; }
    | i%ID > !ASSIGN        < [&]() { return variables[i]; }
    | OPEN > e%Expr > CLOSE < [&]() { return e; };

rule Product =
    l%Value > *(
        TIMES > r%Value     < [&]() { l *= r; }
        | DIVIDE > r%Value  < [&]() { l /= r; }
    )                       < [&]() { return l; };

rule Sum =

I'm trying to find out if there's a sane syntax that I'm missing for doing some bit operations. Basically all I want to do is this
take a uint16, assign it a value
take a uint8, assign it a value
have some type that's 24bits wide
put the uint8 in the front, put the uint16 in the back, send it over the network where it will be split back into 2 valued again. I want to send data over with the uint16 and have it be type tagged with the uint8.

I know I can manually set each bit 1 by 1 using bitwise operators but I feel like there's a simpler way where I can just copy the first half to some memory then just copy the other half with an offset. What am I looking for?

Also am I going to get fucked by endianess if I translate to network order on the server side and translate back to host order on the client side before doing the split back to 2 types on the client?

>>60424190

I forgot to say
>>60424190
>for doing some bit operations
in C and/or C++, I'd like to know how to do it in C but the API I'm working with requires C++ anyway so either works.

>>60424045
It's doing I/O.

>>60424206
Something like this?
x = (type1 << *offset*) & type2
If that's not it I'm sure I can figure it out, I need to setup a test to watch the memory, I'm bad with thinking of binary in my head.

Thanks.

Why isn't there a national licensing programme for languages, like there is for cars and firearms?

We know that cars can kill us, so we require a license.

We know that C can kill us, but we let everybody write whatever they want in it. It doesn't make sense.

You don't need to do this. Networking is byte-oriented.

Note that for things greater than 1 byte, endianess becomes an issue. Basically all networking is big-endian; it would be a good idea to follow that.

>>60424293
My idea is after a data breach, the developer must forfeit the source code to a federal auditing agency.

- If the developer refuses, he is fined for every day he doesn't submit the code.
- If the source code was written in C without a license, the developer is fined.
- If the source code did not adhere to the safety standards taught in the licensing course, the developer is fined.

It seems reasonable. We already accept similar standards in other industries.

>>60424814
So b can get the next number and I can see if the b witht he new value is identical to the new a.

>>60424835
make another variable that holds A until you need to check it against B.

>>60424823
Should have paid attention in class kid.

>>60424835
if A is already equal to b (like you're checking), why do you need to allocate a to b? Just go to the next number.

can anyone suggest some programming exercises to learn C with? I usually just write with python so anything that is better suited to C would be good.

>>60424865

He need an else that stores the new next number. It is clear that this code is written by a guy who didn't practice coding and is just throwing shit at the screen and hoping it works. Writing out a basic psuedocode would have solved his problems.

For starters, you need to learn quantum physics, classical physics, then transistor logic. Afterwards, you can move onto boolean logic and digital electronics, and can then move onto CPU state machine design. You can now learn about machine code and then assembly code. Finally you can learn C and other higher level programming languages.

You also need to cram all of computer science and mathematics in there somewhere.

I'm pretty sure your while loop is causing the loop. Are you changing your "In.available()" value?

while (In.available()!=0){ 

also watch out for this one because it's assigning to 0 and not a boolean logic

In.available()=0

I only use C and Scheme, but I want to broaden my palette to something that is secure (unlike C), fast (unlike Scheme), and easily parallelized (unlike C and Scheme (most implementations don't have native threads))

I have tried other languages but found them annoying. Clojure and Scala are out for JVM, Haskell is out for being too pure, and Rust probably has the worst syntax I've ever fucking seen.

I will try Ocaml next. If you know something else please tell me.

>>60427526
Stop being retarded and just use Rust.

>>60427526
C is as secure as the programmer makes it. If you want to write secure C, stop being so fucking shit.

>>60427526
>Clojure and Scala are out for JVM, Haskell is out for being too pure, and Rust
All of them are trash really.
>Ocaml
That's arguably worse than at least half of the languages you listed.

    int b = 1; int c = 0; int *a = &arg;
    int a_1 = ~(int)a & c; int a_2 = 1;
    for(int i = 0; i < 7; i++) { a_2*=i; } 
    if((int)a == a_1) *a = 0;
    int a_3 = (!a)?(c=1):(b=0); int a_4 = (int)a | (b+~c);
    (a_4)?(int)a >>c:(int)a&0xF8; (int)a<<((int)pow(b,c)+(int)pow(c,b));
    if(*a == 0) return;
    printf("%d", *a); printf("%d", &a);
    free((void*)a);
}

Why is that? C is a mediocre language at best. I don't think that would make it a requirement.

Only relative to absolute shit languages. Which is obvious since "mediocre" is a lot better than "complete shit".

Why didn't you say so in the first place, you fag? Try erlang.

>>60427699
>do not know C
Why not use any other randomly chosen sequence of letters to represent this? "Script" "Kiddie" makes no sense in this context.
Also, where did I say that I "do not know C"?

>>60427668
No one said you had to use it.

I asked you no questions except for one occasion where you evaded the only question I asked you.

In fact I answered your questions:

A webdev/script kiddie simply can't fathom the greatness of C. I get where you are coming from.

A webdev/script kiddie simply can't fathom the greatness of C. I get where you are coming from.

How about you stop grasping at the last straw so desperately and explain how you "know" C if you can't read it, dear child?

>>60427815
>I said "I can't read C."
If you can't read C, you can't say "I know C". Therefore, you don't know C.
Otherwise please say how one can know a programming language if one can't read some programming language.

>People that do not know C

>By being obfuscated
Answer this : "If it's written in a language you can't read is that still "obfuscated"?"
>explain how you "know" C if you can't read it
You don't need to be able to read to speak and listen. This partially applies to programming languages as well.

>>60427905
>you can't say "I know C"
You can. I know how to comprehend spoken English and how to produce it myself, but I can't read it. It's almost the same with C.

>>60427956
>You don't need to be able to read to speak and listen. This partially applies to programming languages as well.
No it doesn't you fucking idiot. Comparisons between natural languages and programming languages are weak at best.

>>60427956
>Answer this : "where did I say that I "do not know C"?"
I answered this already.
That's because you don't know how to read and write C.
>"Why not use any other randomly chosen sequence of letters to represent this? "Script" "Kiddie" makes no sense in this context."
That's because script kiddies are used to scripting "languages" only. If you have your own definitions of these terms than the standard, I am not interested in it.
>Answer this : "If it's written in a language you can't read is that still "obfuscated"?"
Yes. Learn what obfuscation is.
>You don't need to be able to read to speak and listen
You can't speak or listen C, you read and write it. What you listen and speak is not C, it does not apply to programming languages.

I suggest that you head to /wdg/ since you do not belong here.

How do you fetch only a certain table from CURL? I wanna filter it using a class name

>>60427974
>No it doesn't you fucking idiot.
It does. You don't really need to be able to read a language to claim that you know it at least on some level.
>Comparisons between natural languages and programming languages are weak at best.
Which is why I said "partially".
>Given your obvious bait, I don't even know why I replied to you.
Same here.

>>60428060
>That's because you don't know how to read and write C.
Where did I say anything about not knowing how to write C?
>scripting "languages"
Someone who never used them clearly can't be a "Script" "Kiddie" then. Which just shows how stupid your definition of "Script" "Kiddie" is (you said that it's anyone who doesn't know C).
>If you have your own definitions of these terms than the standard
Your definition is itself non-standard, it doesn't refer to either "Scripts" or "Kiddies" anywhere.
>You can't speak or listen C
You can do the equivalent of speaking C, which is known as "writing".
>wdg

>Where did I say anything about not knowing how to write C?
Exactly where you claimed not to be able to read C. Now don't go and tell me you can write C without being able to read C that other people wrote
>Someone who never used them clearly can't be a "Script" "Kiddie" then.
Any "language" that is not C/C++/D or Rust is a scripting language. Example: H*kill, *Caml, C*q, *dris, P*thon etc
>Your definition is itself non-standard, it doesn't refer to either "Scripts" or "Kiddies" anywhere.
See above
>You can do the equivalent of speaking C, which is known as "writing".
Writing is not listening.

>Why would I be using a thread meant for web "dev" when I'm not interested in it?
I don't know, however you certainly do not belong to this thread, so go wherever else you feel like

>>60428195
>Exactly where you claimed not to be able to read C
Do you genuinely have trouble reading?
>Now don't go and tell me you can write C without being able to read C that other people wrote
I don't see anything surprising about that.
>C/C++/D or Rust
>H*kill, *Caml, C*q, *dris, P*thon etc
Trash. All of them.
>Any "language" that is not C/C++/D or Rust is a scripting language.
This is blatantly retarded. If I create a dialect of C it will somehow be a scripting language according to you. I guess x86 ASM is also a scripting language.
>Writing is not listening.
Writing a programming language is the equivalent of speaking/writing a natural language.

>I don't know
I can tell.
>so go wherever else you feel like
I think I'll stay here just to torment you and your kind.

>>60428136
>You can do the equivalent of speaking C, which is known as "writing".
If you can only speak, but not listen (i.e. "read"), you can't know if you speak jibber or actual language.

>>60428329
It doesn't matter whether or not I "know". The compiler knows and the programs it outputs also "know".
