Is it a bad habit to use the same variable name when passing a function a parameter.
For example, using:int myFunction(int var) { ... }
int main() {
int var;
myFunction(var);
... }
Compared to using two different names:int myFunction(int someVariable) { ... }
int main() {
int var;
myFunction(var);
... }

I don't really see anything wrong with it m8. Some people make a huge deal about it and add prefixes to all their variables to say where they're from though. l_ for local, m_ for member, p_ for parameter, r_ for reference parameter, etc etc
>>54406262
Yes. If it's global you also don't need to pass it in the first place.
>>54406378

>>54406262
No.
It's not a bad habit.
Don't listen to people who says it is for no reason.

Lots of it. Just last thread you used a term that no one inside academia would use (and I have a BSc from EU did a year of my MSc in the US, so it is NOT a regional thing).
I'm not going to point it out because your arrogant attitude makes me hope you don't better yourself.

What should I Program?
Programming in python. I have two lists, expressionList and normalisedList. expressionList contains roughly a thousand sublists of the form [IDNUMMER,coor1,coor2,...coor8], each representing a vector. I want to normalise the vectors in expressionList by dividing every coordinate in each vector by the total length of the vector. For that, I'm using this function.def normalisatieFunctie(expressionList):
normalisedList = expressionList[:]
for line in range(len(normalisedList)):
lengthVector = sqrt(sum(i*i for i in normalisedList[line][1:]))
normalisedList[line][1:] = [x/lengthVector for x in normalisedList[line][1:]]
return normalisedList
However, every time I use the function, both the expressionList and normalisedList turn into the same list. Shouldn't the copy at the start (normalisedList = expressionList[:]) make it so that only normalisedList gets changed? I am so fucking confused.
Do you guys think that Udacity courses are relevant enough to add them to my resume?
>>54406691
I think I got it m8.
I agree thata = b[:]does a copy. However, it's only a shallow copy, meaning that normalisedList and expressionList refer to the same set of lists. When you mutate those lists through normalisedList, the changes thus become visible also through expressionList.
c++ add-on upgrade for new software version but it sucks, they made a change i'm unable to bypass with the current version
>>54406691
I could be reading your code wrong because it's very late here, but with this line:for line in range(len(normalisedList)):
Surely you haven't expressed a range there? You've expressed that you want it to go for the length of your list, but you haven't expressed where to start (eg. 0). I haven't used python in a while, but that doesn't look right to me.
>have biased generator
>xor it with 10101010
Would this make it unbiased or am I being retarded?
>>54406790
Actually, no. I'm a dickhead, you can do that in python.
>>54406790
It takes the length of the normalisedList, which is 1012, then makes a list which is [0,1,2...1011].
>>54406792
Depends what biais, here you're betting that this bias is even vs odd in a very specific way, no?
>>54406792
>xor it with 10101010
Just get it to stop consuming MSM and the bias will naturally dissipate if your generator has the power of critical thinking.
>>54406822
In Python3 it's not a list
>>54406839

>>54406760
Independent study is usually always a plus on a resume because it means you can actually take the initiative and learn on your own but make sure that there's something accredited there. From a quick glance I don't see anything that points to a named school outside of their CS "Masters" with Georgia Tech.
I'd also be careful if you're really relying on that as your shining point because while it takes some sort of good looking give-a-fuck to study on your own, pajeets and ching chongs can take the same courses and do the same thing. It sounds counter-intuitive but try to have real extracurriculars or knowledge in the humanities.

Alright. It seems that the class designer really doesn't want you to do that. There seems to be no way to access the private char array of that class, assuming there is actually one (maybe it's a wonky chunked linked list or god knows what, hell, that's the reason for encapsulation). The question is: why do you want to call strncpy_s? There must be another facility for transfering string content that's more appropriate for GS::UniString.

Well it was working before, when the data i have to modify was available directly(as char). They removed it and gave a function which returns this UniString.

>>54407437
No don't do that, anon wasn't saying it would work anyway. But yes, according to the documentation, the CStr is only a read only copy of the UniString: It can be converted toconst char*, but never to char*.
http://www.graphisoft.com/ftp/techsupport/documentation/developer_docs/AC15/GSRoot/GSRootHTMLLibrary/GS/UniString/Constructors.html
>Content is converted to the Unicode representation using the default user locale.
So yeah. Now everything depends on what output your code is meant to produce. UniString or char[]? In the second case: allocate your own char array, strcpy the ToCstr() result into it, and modify it.
What's an easy library or API I can practice with after I'm done with the standard library for C++?

If you're sure it's going to stay as-is, then you might as well use a one-line if for readability.char c;
int i;
if (c == 'A') i++;
Best practice would be to add brackets, so that in the future, if you want to do something in addition to incrementing i, it's easy to add:char c;
int i;
if (c == 'A')
{
i++;
}

This was the code. Because both gotos are indented, they look like they are both part of the if statement, but they aren't.if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)
goto fail;
goto fail;
If the braces are placed like this it's obvious that something is wrong.if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0) {
goto fail;
}
goto fail;
If the braces are placed like this, both gotos are part of the if, same is the indentation implies. The code is wrong, but the bug won't happen because the second goto is never reached.if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0) {
goto fail;
goto fail;
}
If the braces are placed any other way, it would require editing the code without paying any attention to what it's doing, in which case nothing would help.

Now, I understand that this is all opinion-based, but if you're not a NEET you'd understand that clarity and easy modifications are the bread-and-butter of working with many people on the same project.
The initial example, while a bit spaced out, is easy to read for the most retarded of programmers, and easily changed if needed.
Also, the clarity that comes from the explicit 'true'/'false' assignment helps to avoid mistakes like your lack of the negation operator.
I understand your intentions, but the code-golfing just annoys people in the professional world.

>>54409229
In your example, extensibility for the true and false responses to the checkbox results in either continuing to create ternery/one-liner IF statements, or just refactoring to a block.
The preferred method in most group efforts is to start with the block in the first place.
Calling it 'code golf' is hyperbole, but the point remains.

>Also, the clarity that comes from the explicit 'true'/'false' assignment helps to avoid mistakes like your lack of the negation operator.
Fuck no, it's not clear. It takes brain time to realise "OK, he's putting in true in the case where isChecked is false, but false in the case where isChecked is true, so yeah, that's basically a negation, I get it".
Besides It's as easy to flip true and false literals than to not put a negation. Also negation is a concept, showing in code that visible gets assigned the opposite of hidden is, again, as clear as you can get.hidden = visiblecan be spotted as a countersensical thing to do more easily, that's undeniable.

im say one could pass different commands for different systems using system(). that makes it pretty portable.
>>54409546
that's assuming you know every system it's going to be run on
>>54409365
>waaaaaaaah
sure thing, baby
>>54409546
if you consider that portable, by all means go ahead and write it
>>54409293
>portable libs that accomplish the same task
which boil down tosystem("");
Can someone explain to me how the fuck this works?
This is in order traversal of a binary tree, I can not wrap my hand around how it works at all.
public void display(Node root)
{
if(root!=null){
display(root.leftchild);
System.out.print(" " + root.data);
display(root.rightchild);
}
}
To me, in this form. I interpret it as this:
display(root.leftchild);
display(root.leftchild);
display(root.leftchild);
called x number of times down till we get to the left most node.
But then, how the fuck does it progress any further than that? Even if the root becomes null, the System.out.print statement shouldn't print because it's in the if statement???
The fuck??
How does it even make it to the print statement? Isn't it every time we call display, we end up at the beginning of the function again?

you're the baby since you can't handle that people aren't too lazy to put braces around an if statement

>>54409579
Clearly not! Libraries don't boil down to executing external commands, external commands call libraries with an unnecessary indirection. Do you really believe there's no way to "pause", as the windowsians do, without an external command?

>>54409557
>>54409575
well the alternative is finding a library for whatever you want to do running natively on each target system. system() is sometimes useful and much simpler. not always.
>>54409653
>i'm trolling this hard
PUT UP OR SHUT UP FUCKING IDIOT
>>54409645
I don't understand. How can you have statements after a recursion call?
>>54409655
>syntax is too complicated
back to school, kid
>>54409586
There is a call stack, anon. Each invokation of the function is different from the calling stack frame, and upon returning, whether it be to the same function or to a different one, execution jumps back to the calling point.
You're thinking too low level IMHO. It doesn't matter that we use the same function to do a part of the task or a different function: there is an abstraction that lets us call a function and then continue onwards from the calling point, and it works even if the function is recursive.

I have no programming experience.
Is there are tutorials you can recommend to start learning C++ ?
>>54409680
Wait a minute, does it make a new instance of the function that goes along simultaneously with the other ones?
>>54409680
Because it doesn't terminate the function. You can consider the recursive call, then come back up and consider the statements that follow it, just as if a normal function call had taken place.

joke's on you, you're the tard, you have nothing to back yourself up, you have no book or anything which says how to pause an application in a better way than using a syscall
some posts omitted
/dpt/ in a nutshell
>>54409709
YES EXACTLY
Or almost, it's not simultaneous/parallel, the parent invocations are suspended as long as the child runs, just like regular function calls.
>>54409467
>>54409481
>>54409482
Okay that makes sense then. But its not really a program since its for recreational use and pretty much everything I do recreationally is done of windows.
Thanks.
>>54409720
>using a syscall
you don't even know what that is, kid; please leave
>>54409720
syscall = system call != a call to the function system, which serves to invoke external commands

And that's why you use monads
>>54409757
We say library, but half of the time it's a standard library function that's cleaner and safer, likesystem(sprintf("rm -f %s", file))(I know sprintf doesn't work like that, I don't care, it's for illustration) andremovefile(file). As for the remaining half, the external command already does it, so either it's some arcane source code, or there is already a way and a library to do it. Or do I not understand your point?
Yes, if you ask us for a generic way to replace every misled external command invocation with something equivalent automatically, there is none, but it's possible to do case-by-case for a human being.
Also system/exec have legitimate use cases, like shells for example, I reckon

Yes they are. Monads are exactly like trees. Bind takes a normal value, like an apple and turns it into a tree. Fmap can take a function, like a fork, and a monad, like an apple tree, and turn it into a different monad, like an applesauce tree. Join takes an absurd tree of apple trees and turns it into an apple tree. So monads really are like trees.

If you want to be safe, do this I think:(+ (div a 2) (div b 2) (div (+ (mod a 2) (mod b 2)) 2))
