Why?
C++ requires lots of knowledge on inner workings of "metal".
Diving into C++ without a programming background would be painful.
I've started with Python the got deeper into C++, it was a fluent and joyful experienve to me.
Now, I can use/learn any language. I've even passed an top class C# interview (I told them that I don't know about C#) with my C++ and Python knowledge.
They offered me the job.

lol python ewwww
Dima
but good job
NXiss7
I don't use Python
NXiss7
But it's good to have.
And sometimes you just prototype something.
I'm in love with C++, it's my main language.
I love low-level stuff, managing memory, types, classes, being cross platform...
Anything about it.

Hi guys. I have questions. Did you know android ndk?
NXiss7
I just write a crypto lib in C++ and tell my compiler to compile it for Linux, boom, compile for Mac, boom, compile for Win32 boom.
Write once, run anywhere is C++

Yep, I do.
But dunno if I can answer, don't have much time.

Until you use some platform-specific stuff. Every language can be compiled for every platform (if the right compiler exists, obv) but that's not what cross-platform means

I don't use muxh platform specific stuff.
And write wrappers or layers around them if necessary.
I avoid p-specific as much as possible.
It's more WORA than Java for me.
Ludovic 'Archivist'
Mmh, actually I feel like C# is more WORA than C and C++ (particularly NetCore)
Ludovic 'Archivist'
But when I want WORA I tend to turn to Elixir or Erlang

Only issue with that is that some libraries rely on C compiling which may not happen on some platforms as you would expect

guys correct me if i'm wrong, but isn't python full WORA? except threads

It dependa on excpectations I think.
But since every single code is translated to asm and no one writes assembly but uses C or C++ instead, you can use it pretty much anywhere.
That's my experience so far for Windows, Linux and Android.
But the real benefit is that you can use almost any language after mastering C++.
NXiss7

Nope, try using it on Android.
Try distributing it to a client.
Client expects a setup and an exe to click.
With Python that's not that stable (freezers and packers so far). C++ is much stable if you write it properly.

Could someone please tell me why when I pass a 2d array in c, some rubbish value gets sent

Show us the code.
Reasons may be:
You didn't initialize it.
Your indexes go out of bounds.
Your pointer math is incorrect.

The direction array when passed to prontlcs has some rubbish value
Nameful
That's some compact code

any one here for friendship please text me
Artöm
val in lcs is wrong
KEKI
To compile it
Artöm
If you need to have 2d array with runtime sizes use mallocs and create array of pointers to matrix rows aka dynamic 2d c-style array
Artöm
Arrays val and ditection have runtime size so you need to allocate them dynamicaly, that is, using malloc

80% of the internet-facing servers run it, most users' first contact with the web will be "wordpress" or similar and even facebook continues on it.
With v8's release, the first one with a JIT, coming soon you can bet it'll keep on going.

Well, Facebook doesn't actually uses much PHP, they use their PHP derived language

Yes, among professionals. Doesnt offset the millions of wordpress sweatshops.

I see you never dug into a dungpile of either or you'd not take that analogy

Infact i just came back from one ~2 hours ago.

Then you likely know that horse crap smells less and is far less annoying than cow dung

Just the general assessment why a 55mb ~100 plugins wp page is overkill for "use static site generators for this".
