Make a C program that embeds your Python program.

Because that's more or less all any Python -> .exe program is going to do.

MSVC does not support the C standard

That is currently not relevant.
So you think "not supporting the current C standard" -> "not being a good C compiler"?

i don't know why you think this and "complete and utter garbage" are somehow even close.

>>59229849

P = is a good C compiler
Q = supports C standard
P implies Q
Not Q, therefore not P.

The inclusion of GCC and Clang is not necessarily part of the proof, but rather, insult to injury. P implies Q is an axiom. A good C compiler supports the C standard by definition.

>>59229849
>your logic is flawed

You claimed that something which supports the current C standard is a good C compiler. Then you concluded that something which does not support the current C standard is not a good C compiler. I don't know how retarded does one have to be to say that this is valid.

>The inclusion of GCC and Clang is not necessarily part of the proof
Why did you do it then? Do you also add in random shit for every single """proof""" or is this just some special case?
>insult to injury
You do realize that probably nobody here is retarded enough to claim that MSVC is a good compiler, right?
>A good C compiler supports the C standard by definition.
A good C compiler is by definition a C compiler, which means it supports the C standard.
This doesn't somehow mean that is supports the latest C standard.

>>59229871
qt creator is the only IDE i've used that has reliably had no detectable input latency even on a very low spec machine. others have had much higher latency (to the point of being distracting) often even on a much higher spec machine by comparison. it also allows you to disable virtually any feature you don't need/use for a lower footprint, and has excellent integrated cmake support. it also makes setting up kits for different toolchains/cross-compilation, build configs, and deployments very clean and easy

You just need a faster computer.

>>59230030
that was mostly meant to be illustrative of the massive gap in support. but you would be a fool not to use c++17 features once they're adequately supported if you have the option. you don't need c++17 to write good code, per se, but using it allows for better code than was previously possible

A good C compiler by definition can compile the latest C standard. Otherwise it fails the "good" part of its definition.

>>59230042

$180, but yes. never been a problem because i tend to write low-dependency code. in fact i've had projects build slower on my other machine because the build process was bottlenecked by HDD read speed compared to the SSD in the chromebook, though i'm sure that could have been remedied with -pipe. still kind of funny, though

i am saying the resources are plenty and cheap. you sound like a person who grew up during blockade where the only thing you could eat was an unlucky cat. so you got traumatized for life. and now you shun people if they drop bread crumbs when they eat or didn't finish their meal.

if an ide can give me an edge by using more os resources, let it. i didn't buy 64gb ssd hexacore for nothing. if you want low resource usage, why use a power tool, use a hammer. but don't claim hammer is better because it requires no electricity

MinGW is MUCH worse than VC. I had the pleasure of trying to use std::thread in MinGW. It was literally not supported although MinGW claims to support C++11. I had to download another compiler (TDM-GCC) to get it to work.

>>59230577

TDM-GCC and MSYS2 are just different implementations of the same MinGW-w64 toolchain. It would seem that the implementation you had originally downloaded did not come with winpthread, which is what is used for implementing std::thread.

>if ide was a text editor, it would be called a text editor
it is effectively a text editor with a few plugins. editing text is the primary function. all other arguments aside, it should be able to edit text with minimal latency. this is really not much to ask

>i am saying the resources are plenty and cheap
you seem to have a limited worldview. waste for no good reason is simply stupid, but unfortunately is predictably bred by excess. people have a tendency to "live just within their means", so to speak. the more room overhead they think they have, the less they care to optimize. this is bad in general, but certainly also for software. advances in technology should raise the bar for software proportionally, not less so after accounting for developers becoming more lazy

>if an ide can give me an edge by using more os resources, let it
surely, yes. but (1) it should actually be giving you an edge, not giving you the same result at greater cost, and (2) it should be optional, even if not strictly for the case of necessity but rather as a matter of preference

Is D a meme or is it really the language of the future? I've only read the brief documentation on the syntax but it looks BEAUTIFUL.

Can D do everything C can do? Very low level stuff?

>>59230969
You can avoid D's GC and there are clear instruction for that.

I wouldn't design a kernel/driver in D. I see D and Rust as C++, just a step higher level of C.

>>59230987
Whats the benefit of C though? Shits so broken, so many useless broken functionalities in the stdlib

>>59231008
>Whats the benefit of C though?
Not much, older projects are already written in C. C is like the legacy shit that will stay for a while. However I avoid C as much as possible. If you are doing a new project, chances are, there are much, much better, robust and safer options (pick your poison).

>>59231035
>>59231008
Heck I even tell newbies to learn D instead of C

>>59230969
I'm not a fan of D being so closed but from what I hear, absent a lot of nonsense regarding standard library forking awhile back, it's a lovely evolution of C++.

>>59230969
it's nice but if it was gonna be the language of the future it probably would have needed to catch on like ten years ago

>>59231042
As a desktop application developer I can safely say that I will pick D over C++ any day any time. I had a look at Rustlang as well.

No words can describe the horror of C with classes.
Hence C++. I do believe the new kids (D and Rust) of the block are fascinating.

newfag here,
is using switch statement with only 3(2) cases overkill? like so:

switch (number) {
case 1:
    isPrime = 0;
    break;
case 2:
    break;
default:
    for (int i = 3; i < (number / 2); i += 2) {
        if (number % i == 0) {
            isPrime = 0;
            break;
        }
    }
}

.

>>59231252
now I realize I could just put it into a standalone function

>>59231252
you are not using default properly. It should catch non integers

>>59231284
well that's good to know!

>>59230969
>Is D a meme
No. It's a programming language therefore it cannot be a "meme".
It's shit though.

>>59231158
>D
>new kid on the block
D is 15 years old senpai

>>59231252
weak

for (int i = 2; i*i < number; i++) {
    if (!number%i) { isPrime=0; break; }
}

>>59231284
I don't quite understand why
Is that the case even if number is declared as an integer (unsigned) beforehand?
the way I understand it 1 and 2 are special cases and anything else is default behavior
also I'm writing C not C++, if that changes anything

So if I want to build a UI application for desktop, will QML suffice?

I want the application to have menubars, dropdown menus, file explorer etc as well.

I am a C learner, and I am currently working on a project with structs that have pointers as its members:

struct Node{
  enum NodeType nType;
  struct Leaf* elem; 
  struct Node* g;
  struct Node* d;
};

If I have a pointer to one of these struct (let’s call it ptr) and I want to delete it, is free(ptr) enough, or do I need to free first its pointers (such as free(ptr->elem) ) and then free ptr?

The language only nobles and higher society used in England for almost five centuries, as well as the diplomatic language that had been used for over a millennium and that is still pretty much in use today in diplomatic relationships.
Not to mention half of English vocabulary comes from this language. (Sorry, my inner linguistic nerd was tingling)

>They're pretty close.
I guess it’s pretty much “everything that is both in C++ and in C are used the same way”?

using namespace std;

It's very annoying to std all the fucking time, and it decreases readability significantly. Especially when dealing with templates, shit gets so messy.
I'm talking about practical cases.
