>>54175683
This is a fact. Nobody on /g/ who ever recommends C even knows anything about it. Hell, just see in the previous thread the tard, his tree, and the pajeets encouraging him to use incorrect code.
So /g/ I cannot for the life of me figure out how to implement this. Essentially I have a class object and I want to read a file that goes line by line that looks like thisWhat is 1 + 1?
1: 1
2: 2
3: 3
4: 4
2
and assign each individual line to a class object such as .setQuestion, .set answerOne, ect. to each individual question object I have. How the hell would I go about doing that? Posted below is my pathetic attempt at it. Yes, I understand I am not even close.int main()
{
int count = 0;
int max = 10;
ifstream inFile;
inFile.open("TriviaQuestions.txt");
Question q1, q2, q3, q4, q5, q6, q7, q8, q9, q10;
Question list[10] = { q1, q2, q3, q4, q5, q6, q7, q8, q9, q10 };
for (int i = 0; i < count; i++)
{
string temp;
while (!inFile.eof() && count < max)
{
inFile >> temp;
list[1].setTriviaQuestion(temp);
cout << list[1].getTriviaQuestion();
}
}
}
It's c++ by the way.

>>54176409
>no & and | on byte arrays
I am not sure what language you are using, but in C, it is perfectly legal to use bitwise operators on unsigned chars (bytes) and such.
And if you are reading these in as 32 bit integers, of course you are going to be running into endianness problems. Don't do that if the order of the bytes matters.

Consider we have the following in memory:Address | Value
--------+-------
0x100 | DE
0x101 | AD
0x102 | BE
0x103 | EF
We decide to load a 32-bit word from address 0x100 into a register, let's call it r1.
If we are on a Big Endian machine, r1 will hold the value 0xDEADBEEF, or 3735928559
If we are on a Little Endian machine, r1 will hold the value 0xEFBEADDE, or 4022250974
On a Little Endian machine, if we were to increment r1, it would hold 0xEFBEADDF, or 4022250975. Stored back into memory, at the same address, it would look like this:Address | Value
--------+-------
0x100 | DF
0x101 | AD
0x102 | BE
0x103 | EF
On a Big Endian machine, if we were to increment r1, it would hold 0xDEADBEF0, or 3735928560. Stored back into memory, at the same address, it would look like this:Address | Value

>All programming is logical

C++ is fucky, Java stripped C++ of its fuckiness and resulted in streamlined crap, Python is a shortcut to programming, so it's bad to learn first, but great to learn second or third.

It actually has its uses. Namely, it's easier to downcast. Say I have a 64 bit integer. I want to convert to 32 bit. Rather than adding 4 to the address and then loading the word into memory, I can instead just load a word from the same address, since the lowest bytes are stored at the lowest addresses. While Little Endian may seem confusing at times, but it's damn useful.
Also, x86 isn't the only architecture that uses Little Endian -- it's just that it's the most commonly used architecture that only uses Little Endian. ARM and MIPS are both considered Bi-Endian, meaning they can be configured for either Little or Big Endian (and ARM also supports something called Middle Endian, which is a weird thing). The ARM chips in your phone are probably Little Endian.

I'm aware of advantages, I appreciate them. What you quoted I rather treat as a happy little merch- mnemonic.
I'm currently playing with ARM assembly, namely writing a minimal assembler (fuck GAS), that's why I ran into such problems.
I'm still not sure what language would be best to quickly implement it, that would take file handling off my shoulders and let me concentrate on coding up translator. Currently poking Go, but programming such things in it is a seriously annoying. I'm considering Perl, Awk or even bash. C would be nice, but I want to move to ASM anyway, so it's more of a throwaway assembler, to get things started.

That's a tough call. I think the best option would be an array, but of course on start, read the data into the array from a file. I don't think it's worth opening, reading, and closing a file any time you want to access it. In factt that's retarded.
If you're worried about having an array of that size present in your program, don't worry about it. To make yourself feel better, maybe use unsigned chars instead of ints if you have numbers that are always under 256, for example.

I'm sorry I just saw it in a jewtube vid

(.) is a way for functions to be added, and id is mzero

and return () is mzero

What are the advantages of encapsulation?
>>54178808
you prevent the whack-a-mole effect
>>54178808
modular program design. It seems like shit at first but it can be helpful.
>>54178808
a section of an encapsulated program only need to know about certain things, making reasoning easier
>>54178772
one of the best explanations ive seen for this was monads as composition on a railroad track: http://fsharpforfunandprofit.com/posts/recipe-part2/
yes, it's a generalized composition, but it's more powerful than just that.
I love you guys so much I would like to paypal one of you guys a pizza
>>54179125
i accept your offer sir
>>54179007
Yes and the really cool thing is that the same syntax can specify loops. For examplenumbers :: [Int]
numbers = do
a <- [1,2,3,4]
b <- [1,2]
guard (a < 4)
return (a,b)
is roughly equivalent toList<Int> numbers = []
for (Int a : [1,2,3,4]) {
for(Int b : [1,2]) {
if (a < 4) {
numbers.addAll( [ (a,b) ] );
}
}
}

Dude's a beginner and seems normal enough, asking nicely for help. Here comes someone with the knowledge and instead of helping, you imply he's stupid for not having the same experience as you.
You suck dude. We were all new at one point. Try and sympathize, like a human being would.

I know this friendo, my excuse is that I was stressed out irl at the time; I'm sure it did no harm to him anyway
You also suck for being a white knight though, even though you're right
>>54179309
When I was a beginner I didn't ask a bunch of strangers on the internet that have a reputation of being not nice to beginners because I'm not retarded
am i correct in saying the difference between an interface in java and cpp is that in java an interface cannot contain the logic of the method bodies and instead servers purely as a class with method prototypes, while in cpp an interface is mroe like an abstract class where the methods aren't just prototypes but can also have logic inside of them?
>>54179388
interface in java = pure abstract class in cpp
i hate all of you
>>54179406
abstract classes in cpp can have logic in their bodies though right? how is what you said the case then because in java cant interfaces not contain any of that logic and serve as only prototypes?
>>54179413
It's okay pajeet

>>pure
>>54179432
oh thanks i get what you're saying
>>54179339
I almost killed myself because you got angry at me over question lists
>>54179443
Essentially, C++ has the option to define member functions in your 'interface' while not defining others, Java does not (If I know correctly, I don't know Java intimately)

When I see example programs for libraries, I often find people using a lot of global variables, referencing them in their functions, and not passing anything to them. Should I actually be programming like this?

No dont use a lot of global variables, its bad practice. Read the follow:

>>54179501
>the places to look for the bug are localized
only if you completely ignore getters and setters and make all logic for a data type part of the class. which makes it confusing as fuck because now none of the code is tied down to the place where it should logically be.
>>54179656
no, people just write shitty code in examples because of laziness. it gets annoying having to update things to each release of your library so you end up writing shitty/hacky code for the tests/examples every single time

Reposting here since the solo thread wasn't getting posts.
What's the best way to insert an element into a container assuming a finite amount of memory? The course I'm using says to replicate the internal array with +1 size, copy the data over, and delete the original. Is there a better way to insert, without doubling the memory use?
>>54180082
just use a linked list
>>54180082
doubling is the best method
>>54180097
top kek
>>54179917
I'm not sure, but it sounds like a smart autist from /g/ wrote it. Thats why i like it kek. The dude knows what hes talking about
>>54180108
Doubling? What do you mean?
>>54180159
he means have a size (number of elements) and a reserve size (number of allocated elements)
if the reserve is bigger than the size + number of new elements, just increase the size
otherwise, double the reserve and allocate twice as much memory
>>54180159
don't use +1 size, use *2 size
i.e., in C:if (vector->size == vector->memory_space) {
vector->array = realloc(vector->array, 2 * vector->memory_space * sizeof(the_type_of_the_array));
vector->memory_space *= 2;
}
This way you're only reallocing if you hit the threshold 2x your past threshold, it's been proven to be the most efficient method.
Some people think 1.5x is better, because you will eventually claim back memory you once used, see http://stackoverflow.com/questions/1100311/what-is-the-ideal-growth-rate-for-a-dynamically-allocated-array for a better explanation. I personally disagree with this idea, because it assumes that previously used memory is contiguous, unless I'm misunderstanding.
>>54180116
>total lack of CSS
>fuck web devs
>GoToHell
definitely a /dpt/tard
>>54180218
So you're saying that the array should always be sizeof(T) * N^2 bytes long? That makes sense, but what if you approach the maximum memory? EG the array is 30 bytes long and there is 20 more bytes of memory left. Should you go to 50 or should you throw an error and refuse to size-up?
>>54180263
Go to 50
>>54176725
I just found out, someone tried to submit feedback, and it returned an error... I hadn't noticed this bug, thanks anon, and I'm sorry that I couldn't receive your feedback ;_;
>>54180293
Okay, thanks. Another scenario: There is 50 bytes of memory. 20 bytes are taken up by a char[]. How do you size up the char[] to 40 bytes in the available space?
>>54175632

>>54180407
>but muh abstraction
>>54180319
If you can't get enough contiguous memory for the minimum size, it fails
Also, dunno which language you're using but C++'s vector has a shrink_to_fit function that shrinks the reserved memory to the minimum to hold the data
tfw your professor is teaching you how programming jobs work in the real world
>>54180416
Yup, it's simple, formats correctly, nothing superfluous, and even processes quickly. Things most websites don't do these days unfortunately.

It's very actively developed, benchmarks are platform-dependent and compiler version-dependent so they become obsolete rather quickly. Who's gonna bother wasting time running benchmarks and posting results when they are pretty much useless. If you're not too lazy you could just run some benchmarks yourself though, if you don't know what algorithms to implement - check out source code of https://benchmarksgame.alioth.debian.org/ submissions, most likely you won't have to modify code of C# solutions to compile them for .net core, so you could compare them to mono, clang, whatever you want
wonder how Go compares to C# in terms of performance and resource usage

C# uses a JIT compiler (it gets compiled to the native architecture the first time it runs), so except for that first run, both are comparable. C# is a higher level, more productive language, with a much bigger standard library, ecosystem and third-party library support so in the end C# makes *you* faster.
