I've been done with uni and been full time employed for 2 years now. I recently had to relearn c++ (the 5 point course we had was basically nothing), and I keep fumbling on the fucking syntax and semantics of the language.

How would i go about statically linking a dynamic link library.

>>55507366
CRUD.
CRUD all day err day.
>>55507405
take the bytes of the .dll file and append it to a section in your exe
then write a function like LoadLibrary, except make it accept a pointer to data instead of a file path
then call that function with your appended dll data and you're good to go
>>55507366
CRUD
>>55507350
>pointersint* p; //pointer to int
int a=5;
p=&a; //takes the address of a and places in p
*p=*p+*p; //adds the dereference of p to itself and stores in p (which is pointing to a)
That's it for pointers aside from arithmeticchar arr[50]; //arrays are just pointers
arr[4]=*(arr+4); //place the value of element 4 into index 4 (arr[4]=arr[4])
int arr2[50];
arr2[4]=*(arr2+4); //still works becuase adding to pointers is actually p+sizeof(p)*4.
And referencesint a=4;
int& b=a; //reference to A
a=7;
int c=pow(b,2); //7^2
It never gets more complicated than that. If you want to consider references to be implicit pointer dereferences where the value is used that's appropriate. Except there's some type safety like making a const reference.
I don't think you will find a good resource for that because it's so simple.

The dilemma arises in that both are fundamentally unprovable.
I will say that Occam's Razor is not the right approach to problems that are on the surface seemingly unprovable as saying "well this is most likely so let's just leave it at that" is akin to sweeping it under the rug.
But at the same time there really is no way to prove or disprove the problem, and that makes the problem futile. It's like an amoeba trying to figure out how to build a space ship.

So in a function what's the difference between:func(int &foo)
andfunc(int &foo)
Does the first pass a reference to the object, thus you manipulate the object inside the function, whereas the second simply copies the value into a locally scoped variable?
Also, why would you ever want the memory address of a value?
>>55508536
>why would you ever want the memory address of a value?
Edit said value without wasting time/memory copying the data, returning it, and reassigning it.

>Also, why would you ever want the memory address of a value?
To avoid copies.
>>55507562
What's wrong with femdom, exactly?
>>55508613
>To avoid copies.
To avoid expensive copies. You still have to copy the memory address.
Pedantic, I know, but it's best to be 100% clear on these things.
>>55508536
Normally when you copy a value to a function you are outright copying the value to a newly declared variable. By referencing you access the value in the initial variable directly within the function.
I prefer toint func(int * n){}
func(&var)
though.
>>55508536
>why would you ever want the memory address of a value?
Plenty of reasons. Aligning your values on X-bit boundaries can be very useful for instance, since computers only operate on memory really if you have the address of two objects and compare them you can know that even if the content is the same they aren't the same thing. It's a big topic. But for something that's closer to you references can't really be stored in an array. So if lets say you have had an array of objects and you've searched through it to pick out a few. Maybe you don't want to search it every time you want to get at these objects, for instance. You can construct an array of pointers and pass that around so you don't have to search anymore.
>So in a function what's the difference between:
>func(int &foo)
>and
>func(int &foo)
I'm thinking this wasn't what you meant. Because thiscode is identical. The compiler couldn't even distinguish between the two different functions in any way. What you've written there is a reference to an int (both cases). & is used to declare references (in that context). And in other context it's an operator (so it can't be used where you declare).
If you wanted to make a pointer vs reference comparison it'sfunc(int *foo)
vsfunc(int &foo)
The only _real_difference is in syntax honestly. You have to check both for if they're valid or not (assuming you don't have any special expectations on the calling code) they both operate through memory addresses since there's no 'reference' concept on a lower level. It's all just memory addressing. But you can operate on the reference directly without typing:
*foo when you want to access the value. You cna also have the compiler warn you if you dofunc(const int &foo)
That creates a constant reference. Meaning you aren't allowed to change foo.
>>55508432
>memorize the long-ass function names and messy syntax
Never learn the standard library. Solved.
>>55506478
me taking a selfie being the qtest girl in the pic
>>55508536
>>55508666
Also it's worth notingint func(int * n){n[5]=7;}
int array[10];
func(array);
>>55508666
>You can also have the compiler warn you if you do
To be clear. I'm not saying the specific codefunc(const int &foo)
Is problematic. But if you dofunc(const int &foo){
foo=5; //produces error
}
func(int &foo){
foo=5; //doesn't produce warning
}
So you can avoid certain mistakes like that.
You can't really pass a pointer and make sure the function doesn't change it.
>>55508666
Also I think it's worth mentioning that the * is both used for multiplication, declaring pointers and dereferencing pointers. So it can get very confusing. Commonly considered one of the major syntax flaws in C/C++.
I think it's why people don't understand pointers as easily. Because unlike every other case there's no single rule for what * means.
>>55508636
If the address is already stored in a register, then nothing will be copied.

>>55509035
I'm gonna be honest with you I constantly reference documentation for syntax especially with pointers and type declarations because I use a few different languages, the more I've learned the harder it is to remember which language syntax is which since they're all just slightly different enough.
I feel like the concept is all that matters anyway, as long as you know what references are for and how to use them you should be fine.

Added ability to search through series now. Sort of works well. It's very fast, and only returns the series if any of its episodes have been posted.

Dear /dpt/ ,
I fell for the k&r meme, I read it and I found myself skipping most of it because I pretty much knew most, if not all, of these stuff. I was looking for something that would not only teach me something, but would also give me examples on how to actually make something useful, something useful being something else other than fizzbuzz tier programs. In /g/'s library you can find O'Reilly's Practical C, but from a brief flick through, I noticed it doesn't teach anything better (maybe I am wrong).
I will move on TCP IP sockets in C, which seems interesting, since I have no knowledge on networking. However, I would like your opinion and advice /dpt/. What do? How can I move on, gain experience and actually make something, as I said,m ""useful""? How did you move on from this situation /g/?
With lots of platonic love,
Another /g/tard
>>55509035
Ah right coming from a C#/java background this is a good question.
In C/C++ if you typefunc(int foo){
foo=5;
}
The calling site won't see that change. Because a copy was passed. The function was just given the value.
If you typefunc(int& foo){
foo=5;
}
orfunc(int* foo){
foo=5;
}
The calling site will see the change.
References and pointers are two entirely separate concepts. Which makes the choice of the & symbol for references incredibly dumb.
>Not a big fan of the syntax
Yes. Everyone hates C/C++ because they're crappy languages with either poor expressiveness, confusing syntax or they're simply sub-par (like templates metaprogramming). They just happen to be the best available for what they're good at right now.
But this is an insignificant problem. You will get used to it.
>>55509035
Yes, any change to foo within the first function will modify the original var that was passed to the function, in case of the second one, it creates a copy of the original one and operates on that copy.
>>55509147
>func(int* foo){
foo=5;
}
God damn it. I meantfunc(int* foo){
*foo=5;
}
Doesn't help you or me to make mistakes.
What I wrote:
>func(int* foo){
foo=5;
}
Would set the address of foo to 5. I think most compilers generate (solvable by casting) errors for this. I hope they do anyway.
>>55509127
Books teach you the language, it's your job as a programmer to make something useful with it. If you don't have any idea of what to build, learning how to use the tools will not be valuable to you.

>don't learn how to use a hammer if you're not going to build a house.
What kind of retarded niggotry is this?
virtual functions are fine if I put all of the processing inside the function and not run the functions in loops, right?
I am trying to build an audio oscillator and it made most sense to me to have a general 'wave' type and have more complex wave types inherit the base wave type. That way I can throw all the waves into a main loop with no problem.
is this a good way to go about this?

Networking is mainly about interacting with the OS from the programming side. Maybe learn about TCP/IP or UDP first?
>how to make something useful
Think about what you need to do something useful. I like games, both as example and simply like them. Games can be arbitrarily complicated. Games do everything and can do everything because they're programs that take some form of input. Do whatever is fun to do with that input and produce an output.
I think what you're really asking is 'how do I learn how to write software well'. Because the barrier to entry for actually knowing everything you need to make something 'useful' is incredibly low.
>>55509235
It's sensible. You should know what a hammer is though, so you can learn to use it.
>>55509242
I don't see why you'd need virtual functions. you haven't really described where you'd need them.

>>55509235
That's not at all what I said, you've got it backwards.
I'm asking what their goal is, if it's to build a house, learn how to use a hammer, if you already know how to use a hammer reading another book that teaches you how to use a hammer is pointless.
In the same regard if they're not going to use sockets then why learn it now?
The whole point is you need a goal to "step up" to otherwise you're just learning random things, I can't give advice on how to "step up" if there's no obvious end goal to step towards.

See this is what confuses me.func(int* foo)
{

V8 does not optimize functions that are longer than 600 characters or something like this. This is counting newlines and comments inside of function bodies so the chances are these few new lines that you add are exceeding the character limit. Why would you subject yourself to JS?

Very good!
A lot of my experience came from doing just that, set an achievable goal that requires some of what you already know and maybe something you don't know, it forces you to apply your knowledge while also learning something new and practically useful, first hand.
Refactoring can certainly teach you a lot about design too, those "I should have done it this way to begin with" should stick with you and you will next time.

google, or really whatever SJW does google's doodle things has a real thing against white men, in the picture those are men who achieved something, they are all white but google doodle celebrating their achievement is diverse and inclusive TM.
They do the same shit for historical figures, they are never white. They are always brown for some reason. Shakespeare was brown
Also, fun example of this progressive bullshit was some american military holiday where in the front there was a brown woman next to her was a black man, on the other side an asian man and all the way in the back is the white man who consist most of the USA military, I even think it was something about WW2 so the doodle would need to be all white basically

Now, at the start you won't really get that many differences between Python2 and Python3, pretty much the only difference you'll see is that in Python3 print is a function, and needs (). If you keep little changes like that in mind you can go through it.

Unity is a brilliant 2D engine aswell. I would know, since I've released a 2D game with unity. It has it's flaws (no 2D shadows & poor 2D animation support is just some) but it's certainly good enough to make something with.
Monogame is awesome aswell. I can't make anything fancy with it personally, but I've seen alot of other people make awesome stuff with it.
I have also heard good things about LÖVE and Godot, but those are a little more out there.
>>55510319
I don't know about chrome or javascript, if you could check each folder and see what the highest percent of bookmarks lead too and then use that as the first offered bookmark folder, the second offered could be the second bookmark folder with the second highest concentration of bookmarks from that website.
so if you have two folders: music, videos, and they both have youtube bookmarsk inside of them, but like 70% of the bookmarks in music folder are from youtube while only 40 % of bookmarks in the videos folder are from youtube. Then you next time you bookmark something from youtube it first gives you the music folder and right below it the videos folder and so on.
If that's possible, it would make bookmarking so much easier and faster. Half the time I just put everything in other bookmarks because I can't be bothered to look for a specific folder

>>55510472
Yeah, I'm working my way through monogame stuff because I'd like to learn programming while I do it, and unity is mostly scripting, if I understand correctly. Plus, deservedly or not, it has a stigma as low effort in the gaming community due to people just buying premade assets and throwing it all together, so if I do release something I want to avoid that.
It's slow going though, because monogame doesn't seem to be well documented, because they basically say to use XNA docs, so.

Anyways. Yes. Monogame is a bit tougher, but you will definetely be happier with yourself once you kow your way around it.
>unity has a stigma as low effort in the gaming community
I wouldn't really say that. It's true that there is some faggets out there who just slam bullshit together from the asset store, but most of the proffesional part of the industry is ignoring the steam-greenlight shit and the shit part of mobile. (not all greelight is shit, but the shit part is ignored) and once you put on those glasses, unity doesn't look half bad. Hell.. Even Heathstone was made in unity.
Still. Good on you for using monogame man :) Keep it up! Hoping to see your games soon dude

I'm seeding it with portions of short stories and flash fiction that I wrote over the course of the past few months. Setting is something like early colonial American with heavy folkloric/fantasy influence; mostly creature x human, dubcon, transformation.

>>55510685
Eh, the barrier to entry for unity is much lower, so people see more crap with unity. Among my friends and aquitances at least, people are wary of unity games

References are pointers that once declared cannot change the object they refer to.
>>55510771
Pointer points to a place in memory, reference is more like alias.
>>55510815
So if you clear that memory, will they then be non-changeable dangling pointers forever untill you delete them?
>C++ newb here
>>55510771
>what's the difference between those two concepts in C++ specifically?
Aside from certain limitations references have (some helpful, like const references) there's no difference. In any scope where a reference would not be a variable on its own a pointer is just the same. In any scope where a reference can not be compiled away it's just a pointer.
They're incredibly similar.

Depends on context. You can't answer this alone.

A reference is exactly like a pointer, except that it only lets you manipulate the value it points to, not the contents of the pointer itself. So you can't do pointer arithmetic with it, and you can't change what it points to. The syntax is different to enforce these limitations.

In ncurses you'll basically have a loop that is waiting for some key press. Following vim's example, if you detect a colon being pressed, you can open up a command line. When they press enter, parse what they typed in. "w" save, "wq" save and exit, etc.

So I was trying to get the hang of IO in haskell, so I wrote a little program that gets the ID3 tags of songs and renames and reorders them into folders based on their tags.
Obviously this was always going to be heavy on IO but nearly all of my functions started with a "do", and it felt I was doing a lot of imperative style programming. Is there a lot of this or does it depend what you're programming?
I guess there would probably be less IO if I knew what I was doing, haven't got onto monads yet in my tutorial so was kinda fighting with the compiler but it's done now and it seems I get less bugs with haskell than when I made the same program before in python

Please indent your code correctly. It makes it so much nicer to read.
>//call function
>void strengthRanNum();
>void intelligenceRanNum();
>void charismaRanNum();
You're not actually calling any of the functions there. You're just declaring them as prototypes.
Even then, you're not passing your struct as an arguement.strengthRanNum(&c);
intelligenceRanNum(&c);
charismaRanNum(&c);
is what it should be.
>srand(time(NULL));
You should only call that ONCE at the start of your program. All of your things are going to have the same value if you keep reseeding it.
>>55513097
also you could write a function to get all the data at once, so in handleTags you end up doing
(artist, album, title) <- TagDetails t
