The cons for C++ can be summarized as follows:

1. MUCH more complicated for beginners due to an overabundance of language features, and a general need to understand how those language features work to understand best practices.
2. Programs take longer to compile because of templates, and depending on your compiler, may produce some rather incomprehensible error messages.
3. May not target as many platforms as C (embedded platforms), may have issues with ABI backwards compatibility, or compatibility between different compilers on the same platform (MinGW, MSVC++).
4. General disapproval of certain subsets of C++'s language features, depending on which language the complainer comes from (some don't like OOP, some don't like templates, some don't like exceptions, etc...)

Overall, it's a language designed by committee, that is constantly evolving, which can be incredibly useful to a power user and incredibly confusing to anyone else.

I use gcc, I've always used gcc. I will keep using gcc until I have a reason not to.

>>58612160
>they both produce around the same speed code
Historically, GCC has been better, because it's a more mature compiler.
I still think GCC is still slightly faster in most benchmarks.

>>58612037
I think bigger than all of that is that they forster an idea of performance programing that distances itself from hardware in ways that are completely unnatural. Every abstraction they have is there to avoid you being platform specific. So when you need to use the language for what you generally use C or C++ for you have to struggle a lot. For instance if you care about memory alignment, as you often do, you have to start using your own allocator and not the 'new' in C++. You'd think telling C++ 'hey start associating all my new calls and delete calls to this allocator instead' would be easy and efficient but it really isn't. You overload the operator new per type.
Similar problems are all over the place. With its promise of being very open to your style of programming (multiparadigm, has tons of facility to express yourself) it all tends to be extremely difficult to work with to get anywhere. It's similar for most details you may care about, a lot of work to get done. Some blame C legacy but I think it's mostly about C++ legacy at this point.

It's also important to note that the C approach of just writing functions that do just what you want and calling those (also available in c++ obviously but should you use C++ because its similar to C?). It's a more attractive proposition to go that route. And unless you're programming alone you're at risk of other people using the C++ that's inconvenient to work with.

If C++ had some proper constraints you could place on programmers it'd be great. Now many industries rely on external tools to manage their programmers. It's not what you expect of a programming language as inconveniently big as C++. That you need more tools than they offer to get good code.

>>58612132
It's mostly quotes you can find everywhere.

I'd say the quote Dijkstra made about California is a bit misleading because it was not intended to spite. Though he did write a letter pleading for his university not to teach C++.

>>58612234
He wrote one pleading not to teach Java, don't know about C++

>>58612181
>historically
Really? Clang is really new and its been better for most of its life.
I'd say unless your platform only has GCC or has poor support for clang (is that still the case for Windows?) go with clang.

>>58612212
>For instance if you care about memory alignment, as you often do, you have to start using your own allocator
how is that different from C?
>You overload the operator new per type.
at least you have the option to do that instead of having to use different functions for it in C

>>58612274
I don't think you get my point. And the 'at least you have the option.. ' makes me not want to explain further.

>>58612253
>shilling this hard
clang is mostly worse or roughly on par with gcc

>>58612239
I'm misremembering.
When pleading for them not to teach java he also said
"—usually it turns out that their undergraduate curriculum has not recovered from the transition from Pascal to something like C++ or Java."
That's probably where I got it from.

1. Platform-specific anything doesn't belong in a language spec. Alignment on addresses more fine than 8-byte aligned isn't common except for some SIMD things, in which case you're probably going to only need one or two different struct types to make a different operator new for.

2. High performance computing and retards don't mix. If you need to manage a bunch of idiots, clearly they shouldn't be working in C++ in the first place.

>>58612431

Perl is gross.

>>58612434

>>58612436
Make sure you loop through the indices and not the elements themselves, then you can just do i+1 without searching.

A language intended to make performance oriented code easy to work with should have the facility to put platform constraints into your code easily. What I wrote is an example.
>only a couple structure types
Depends. If you want to couple code together a lot you can get away with very little.
The C approach would just be giving you an aligned pointer of appropriate type though. It's a homogenous solution.
>2.
Well we can't exactly choose how good programmers are. We don't live in an ideal world. If we could just choose this language choice is fairly irrelevant. We'd just put someone on writing nice tooling for brainfuck.

>Zapcc is a c++ compiler, based on Clang which aims at being much faster than other C++ compilers. How they are doing this is using a caching server that saves some of the compiler structures, which should speed up compilation a lot.

Header: There is a function somewhere called Foo::bar with type signature int(int) somewhere, probably in another compilation unit.
Source: Export this function, call it Foo::bar and give it the type signature int(int)

Namespaces don't change anything about how compilation and linking fundamentally works. They just change how the name gets mangled. When you do something like "using namespace Foo;" you're basically saying "If we don't try this identifier bar somewhere in our declarations, try Foo::bar before deciding to throw an error."

Anything. I meant clang the compiler, not the tools with it. I haven't tried them out yet.

Particularly I was wondering about linters or things that can catch obvious bad patterns beginners may make, or something to display shorter syntax for the same operation. Like

IDA hurts my brain.

>>58613215

Well, the first of these bytes is '\e', the escape character. Typically, the character that follows that is a '[', however it seems this one is followed by a ')' instead, meaning it's not using a standard CSI escape code. This is hard to find documentation for, but I found this:

>>58614160

nice weebum for retards you got there.

>>58614177
FYI we use different versions of clang, mine is from the msys2 project, I don't know where yours is from but it probably expects the native windows stuff instead of the mingw stuff like mine, so you probably need to install the Windows sdk since that's where kernel32.lib is from, then tell the linker where it is. You'll have to read about compilers and linkers, if not now, when you start using external libraries and a build system like make.

Stuff like this is why I just use msys2 instead of installing GB's of Microsoft stuff just to compile hello world. That being said I have to install it anyway for third party project but still I like to avoid it when I can.

How would you describe different skill levels of programmers? Like beginner, intermediate, advanced, for example. And how do you get to the next stage from the one you're in now?

-libpath doesn't work

I have all of these.
I tried adding a directory to the PATH on the environmental variables but that didn't work.

Is there a way for CMake to automatically use every source file under a directory WITHOUT having to regenerate the makefile when creating a file, trashing the whole build, or should I just trash the whole thing and swear to never use anything else but plain Makefiles, and shit on CMake online on every occasion I get for the rest of my life?

CMake doesn't really make generic makefiles. That said, if you generate a new makefile, I don't think it's going to trash all of your existing object files...

You see, I get the opposite case, because open source devs don't touch Visual Studio, unless it's a really big project, in which case, they may support both Visual Studio and MinGW. Otherwise, they just assume you're going to be on a Unix system, and Windows users can figure shit out themselves. If the project isn't heavily dependent on Unix system calls, or at least has some forethought put in to get it running on Windows, it will compile with MinGW alright. Otherwise, you may have to tweak shit around.

I was having the same issue a couple of years ago. Working 60+ hours a week as a fast food manager, and nearly impossible to attend fulltime class (while being awake).

I quit the job as soon as I had enough cushion for 3 months rent/expenses, took a chance on the first IT company to give me an interview for a jr. sysadmin/automation role, and they even let me have every Monday off to drive 2 hours to the university and finish my last classes.

Doing quite well these days, making well over the US median income, plenty of days off, traveling often (work and pleasure).

All I can say is that sometimes you have to take a chance, and get the fuck out of your dead-end role and push into the field you want to be in. I got lucky, no doubt about that, but you've got to make the effort.

If you've actually got two apps developed that you can show off, that's a very very good thing for interviews.

Places like plebbit will tell you that you need to have a plethora of projects and know long lists of buzzwords, but if you're a functioning human being and you can demonstrate that you're not just another fag looking for easy cash, someone's going to hire you.

As long as you aren't like the "manager" I have who just tried to cover up that he didn't finish a database he was supposed to have set up back in late November until the 13th by blaming his coworkers, you should be ok.
