Have fun hunting leaks.
Probably a stupid question for anyone with decent understanding of maths, but..
I want to translate the the mouse cursor X coordinate to an angle between -45 and 45.
The coordinate is a fixed point number from 0.0 to 1.0 with 0.5 representing the middle of the screen, so I multiply it by 2.0 and subtract 1.0, then multiply it again by 45.0.
This makes the angle appear when the cursor is at the center or at either screen edge at 90 degree fov, but wrong in between. What should I do differently?
why is gcc compiling code wrong so often?

nice work.
I'd like to learn programming and become good enough to employ the skill professionally, at least at the basic or medium professional level. Actually, I want to major in information technology and organizations, so my future job will not primarily be programming oriented, but a knowledge of it will definitely be valuable.
Now, everyone online who knows programming appears to be an autistic retard who is 100% unwilling to share their knowledge without being arrogant and gloating. It's weird because there really isn't anything to gloat about. Programming monkey jobs may just as well be shitty as they may pay well.

>so I multiply it by 2.0 and subtract 1.0, then multiply it again by 45.0
Wait, why?
If you want 0...1.0 to go to -45...45, then you need to multiply the angle range by the [0,1] value, then subtract 45.double map( double minRange1, double maxRange1, double minRange2, double maxRange2 )
{
return (maxRange2 - minRange2) / (maxRange1 - minRange1) + minRange2;
}
// OR, more specific to your case
int angleMap( fixed input )
{
static const int minAngle = -45;
static const int maxAngle = 45;
// don't use magic numbers, pls
return (maxAngle - minAngle) / input + minAngle;
}
I do not know what you are using, but the vast majority of language standard or typical libraries already have a mapping function, since mapping a value that falls in one range to another is a very common problem.

> One of these days, C++ WILL have (optional) GC.
Welcome to 5 years ago (GC was added in C++11).
Note that it's the implementation's option, not the user's. The implementation is required to tell you (via std::get_pointer_safety()) whether or not unused objects will be freed automatically. It isn't required to give the program any control over this.
>>52940221
Write the library maintainer a rude e-mail.
Are you kids still using Python and Ruby?
>>52940245
That's true, actually. The problem is that it's optional for the implementation. Implementations should be required to have optional GC to be compliant.

Dear /dpt/.
Do you know any software for easy GUI making in Python, like Lazarus? I mean the "drag and drop elements" ones.
I tried looking for one, only found Monkey Studio (which is abandoned project) and some "wxglade" one, in beta state.

}
return (int)sum;

>>52940433
>>52940452
There's also this:
https://kivy.org/
>>52940358
You appear to be confusing tab width with indentation step.
Tab stops *are* every 8 columns. That's a universal constant, even if some software likes to pretend otherwise. The kind of people who make such things configurable probably also let you configure the value of pi, just because they can.
The problem with making tab stops configurable is that your code stops being formatted correctly the moment it leaves your PC in your mom's basement (professional programmers don't do this shit).
>>52940453
What am I supposed to do then?
I tried adding the main header file to the project and it still didn't work. Am I meant to literally include every file within the library?
Is there no way to install it/turn it into a dll/lib? The github page only explains the UNIX way of installation, but I have no clue how would that correspond to windows.
>>52940497
The guide shows you how to dynamically link the library using GCC. When you dynamically link it, you can just include the header files you want.
Apart from installing gentoo, use something like MinGW to build it.
It's for a mod in a strange game engine.
>>52939804
It wouldn't make much sense without explaining the intricacies and limitations of said engine, otherwise I would.
>>52939870
>>52939932
The engine doesn't use radians but degrees, fixed point angles and byte angles inconsistently. It's a headache, but I'm sure it's not the part I'm getting wrong.
>>52940063
>If you want 0...1.0 to go to -45...45, then you need to multiply the angle range by the [0,1] value, then subtract 45.
Thanks, my current way is only trial-and-error'd up and I fully intend to make it cleaner and more efficient once it works. I'll use your code as a template.

Java has primitives for when you don't need the overhead of an object. "int"
Integers are objects with more capability.

it's always value equality. in the case of objects it's the value of the reference. in java you are always dealing with values.

Let me reiterate, C# and many other languages support unboxed integer type first class and treats it just like every other type instead of making stupid (and outdated) exceptions like Java does.
>>52941273
why the fuck should it be an object? an int is an int, you don't need to sprinkle magic properties for it. typical fucktarded Cshart

Fucking moron
1)
Integer a100 = new Integer(100);
is shitty language design
2) Equality of the references. REFERENCE EQUALITY.

Which, as we've discussed before, is boneheaded default behavior in a language where memory management is handled automagically.
A superior option would be to have == call .equals() and have .referenceEquals() to check ref equality.
>>52941411
Why is overhead necessary for objects?
Let's say you have a class A with a method foo()class A {
public void foo () { this.... }
}
Then you have an object 'a' of type A and you want to call its foo() method.A a = ...;
a.foo();
Because we know that 'a' is of type A, we know exactly where the foo() method is located and to make the 'a.foo()' call. It would be equivalent to it being implemented likeclass A {
public static void foo (A this) {
this....
}
}
A a = ...;
A.foo(a);
Now we know that methods (which are what make objects, objects) have no real overhead in determining where their methods are. Then, stuff like '+' could be implemented as a "method" and inlined without any difference in performance.
I'm not great at explaining this but the only reason for there to be overhead is in generic programming, In this case either
> do what C++ does; re-generate code for each instance of a generic method. No time overhead, but potential bloat
> do what Java currently does; box it. But a sufficiently not-retarded type system should be able to know hide boxing from you instead of introducing "Integer objects"

having them doesn't support the argument that C# is cleaner, simpler, more elegant and easier to learn than java

Thats god to know, but I still dont understand how to properly install PyQt. When I downloaded it via repository, I just got folder with various scripts.
>>52941549
No, the reasons that C# is simpler, more elegant, and easier to learn are not intrinsically related to performance.

You're as bad as a python user.
== checks for the specific object, not just an object that happens to have the same state
it's perfectly fine
>>52941545
Your explanation only works when you don't have to worry about overridden methods.

>>52941590
If only operators were actually methods, then not only would this be a solved problem (some types couldn't be compared for equality), but we'd actually be able to overload the operators.
Too bad Java is shit.
I like the Integer == Integer problem because it shows three of my biggest language-design qualms of Java: primitives, no-operator-overloading, magic syntax and conversions (Integer + Integer, Integer x = 123)
only fucking Cshart codemonkeys use things like == or .equals( _ ). most algorithms don't need it
>>52941606
If you had to explicitly specify which methods can be overloaded (don't people already do this using docstrings in Java?) then it wouldn't be a problem.
>>52941650

4 levels of indirection, you're killing your poor cpu's caches, prediction and pipeline.
I would make the structure like this:typedef struct {
unsigned int sizex, sizey, sizez;
unsigned char cube[];
} cube_t;
cube_t *c = malloc(sizeof *c + x*y*z);
making use of C99 flexible array member and just a single allocation.

It's not either or, you use them in completely different situations.
>>52941683
how about you give an example of an interesting situation where you check if two objects are equal.
>>52941665
You can declare methods 'final', which prevents them from being overridden.
Modern Java VMs are probably quite good at detecting and optimizing methods that could be overridden but aren't.

You are more likely to compare primitives than objects in you're code tbqh senpai
>>52941775
Which do you use more for objects
>>52941699
i forgot what the difference was fugg
>>52941807
you'd use != null or == null or maybe object1 == object2
string1.equals(string2) maybe but only for fizzbuzz tier newb programs or for some sort of codemonkey CRUDshit
>>52941807
Well considering "==" only checks if both objects point to the same address in memory, I'd have to go with equals()
I suppose there's no way to set the sharing mode for a file with C's file api like with winapi's file api, is it? I want to open a file(config file) at startup, keep the handle during runtime and disallow editing/deleting it without the handle(outside the application)
>>52941863
>>52941844
thx that's what I kind of thought
>>52941601
also, objects contain and manage their own state. you should normally never have to "inspect" the entire state of an object by using .equals()
>>52941345
int is an alias for System.Int32, faggot
>>52941857
So wouldn't it be better if their behaviour were switched?

do you really think the fact that a language is the most popular means the creators had good taste or even knew what they were doing?

You could name your function something retarded and have no clue what it does.
If your developers are operator overloading all over the place, it's their fucking fault. Equivalent to naming variables/methods 1-3 character abbreviations. Basic operators should be overloaded for basic things.
