just yesterday someone was sperging about java and go not having multiple inheritance. he thought it was NECESSARY to have multiple inheritance. fucking contrarian edgelords

hardcoding public keys into a client vs requesting them from a trusted third party
Hudson Martin
there is no problem. you can require the user to update their client if you change the key
Jackson Ross
why should i need to learn javafx8?
Lincoln Russell
It's initialized, though.
What's the problem? It's obviously going to use the default value for int.
Jeremiah Thomas
a was read, but it has never being wrote (before)
that's an uninitialized variable usage
the other user claimed that a good compiler with all warnings activated should point it
the other user claimed i'm kinda sure that valgrind would complain about it, dunno about the compiler (it should imho)
John Fisher
dont, write html apps instead
Eli Ward
it's not exact. there are false positives and false negatives.
Tyler Taylor
only b has being initialized, and there isn't "default value for int" at all
actually now that you said it, since he didn't set any optimization flag, g++ would compile with -O0 which actually does zero fill your variables for you
using any other optimization flag, it won't tho
so you would read garbage on a
Aaron Murphy
>there isn't "default value for int" at all
Anthony Russell
just because your baby language compiler zero fill your memory for you doesn't mean that zero is the "default value" of any memory at any given moment
Andrew Scott
Excuse me?
Anthony Morales
global and static vars do have default zero values thoug
Leo Perez
I'm making a small software to design prestressed beams as a final project for class.
I'm using >python since it's easy and it works and I'm not even a real programmer.
I need something to make an interface though. Could even be something like a local page that runs on the browser. It's just something to let the user change the parameters of the design (some arbitrary numbers) on the fly instead of enter everything through command line.
What's the easiest way to do that?
Caleb Howard
Just finished up my first programming book, looking for a new beginner friendly Swift project to get some more experience. Was thinking about maybe expanding on the final project's idea (rock paper scissors game) and taking it to the next level, making it an RPG with HP, item shop, maybe even dungeons or something. Nothing serious, just for fun.
Emoji clown could be first boss or something idk

It's not that bad if your code isn't perfect, right? I mean even the best programs must have some ugly chunks here and there
Hudson Lopez
You work in a business that requires a high performance application that need to display streaming information in a consistent and easy to digest UI.

Concepts still didn't make it, so nothing particularily noteworthy.
It did add more ways to initialize stuff though.

It's not like C++ already has way too many ways to fucking do that.

Finished an exe that compiles my C/C++ files by drag 'n' drop.
It was supposed to only take me a few minutes but it instead took me all day.
#include
#include
#include
/*Simple all-purpose C/C++ command line compiler drag 'n' drop time saver thing*/
int main(int argc, char **argv){
if(strrchr(argv[1],'.')==NULL){
printf("\nUnrecognised file type.\n");
return 0;
}
char fileName[40], output[80];
strcpy(fileName, (strrchr(argv[1],'\\')==NULL ? argv[1] : strrchr(argv[1],'\\')+1));
char *fileExtension = strrchr(fileName,'.')+1;
*strrchr(fileName,'.') = '\0';
if(strcmp(fileExtension,"cpp")==0){
printf("\nCPP file detected.\n");
snprintf(output, sizeof output, "%s%s%s%s%s", "c++ \"", argv[1], "\" -o \"", fileName, "\"");
system(output);
}
else if(strcmp(fileExtension,"c")==0){
printf("\nC file detected.\n");
snprintf(output, sizeof output, "%s%s%s%s%s", "g++ \"", argv[1], "\" -o \"", fileName, "\"");
system(output);
}
else{
printf("\nUnrecognised file type.\n");
return 0;
}
}
Usually, I type everything in the CLI. This'll make compile less of a hassle.

The C++20 standard looks pretty nice though:
en.wikipedia.org
Kevin Powell
it compiles both of them
Julian Perez
He means entirely
Andrew Lopez
Well, it now has more special syntax in case you want to initialize stuff inside an if or a switch statement!
Leo Torres
The first person in this thread we can officially declare autistic (although i see a few before him who are majorly suspect)
Absolutely, but just because you said "lads", i will assume you asked around on Facebook or another equally abhorrent website and found One.
That's actually pretty nice user, you have my approval.
>G++ >.C >C/C++ files
No wonder it took you all day, you seem like the type of person who would need a helper just to turn on the computer.
I'm implementing my own variation of the XMPP protocol in a Client app i have to write, it's 1am and i haven't slept in 2 days and won't get any tonight. So decided to trigger a few fags who can't handle it, instead of doing my actual work. of course.

C and C++ are different languages. They are designed by different people and have different goals.
It's not helpful at all to think there is any relation between them.

I could throw in java as well: I do that from the CLI too.
I have no idea. I have no idea on where the difference lies between the g++ and c++ compilers.
Also, I likely have an actual C compiler but I wouldn't know which one it is in the MinGW bin folder.
I wish I knew what you were talking about.
I think I had a look into makefiles once before but couldn't make heads nor tails of it.

this whole hobby-project of mines is novel as it is so I made a compact version that that renders a cube just for fun, inspired by that c code that generates an ascii mandelbrot
Owen Sanders
g++ is the C++ frontend to GCC. The C compiler is called gcc.
Jayden Ward
Personally i only use python for quick scripts or for integration in other code as a quick binding. It's a fun language to use nonetheless, although the indentation is annoying. Its packed with a lot of needless shit though, from what i can tell.
Nathaniel Evans
>Think there is any relation between them

Your delusional to think they aren't related, and vastly similar.

By that logic, C# is just as related to C as C++ is.

I never did that you colossal moron. Oops, I guess I did now. As for a concrete example, C++ started out as being called C with Classes.
