there are so many you should tell us first your case
Maybe I need many

I second this.i also thinking a bit why I need to learn c&c++ in 2022. Never underratting those awesome languages.

(while I do think C++ is ultra-complex to me I also think that Rust even more complex to me lol)

All of them
so you want to do everything
that doesn't help with the choice 😆

Just tell me the most important languages and their usecase would be enough already

you're still missing the context
"most important languages" for WHAT ?

Look there are some fields, Haskell is for example the most important language for math

Typescript for web application

Javascript also for web

Guys please check my code...why does the second for loop not execute?
Ludovic 'Archivist'
So tell me every language and their usecase
C++ performance, number crunching, low level systems, abstractions go up from web devs/app dev to down in direct hardware manipulation
C: systems, number crunching
Ruby: light scripting or apps where performance is unimportant
Python: same as ruby + datascience
Lua: game scriptin, industrial applications scripting...
Tcl: scripting, test automation
java: portable apps
Scala: portable distributed servers
Erlang/Elixir: large scale telecom or distributed software
Haskell/Ocaml: compilers or interpreters
Go: microservices and Plan9 programs
Julia, R, Root, F#: data analysis
VB.NET, C#: desktop and web apps, games, build systems, mobile apps
Kotlin: Mobile apps
Javascript: Web dev, MongoDB interaction
Prolog, Coq: math proofs
Lisp, Scheme...: Scripting, prototype apps
Here are a few example, of course it is still possible to drive a nail with pliers, but a good engineers uses a hammer for that

it's not
It's probably R instead.
Nomid Íkorni-Sciurus
I wanted to show him that it is impossible to summarize it to give them what they want
Ludovic 'Archivist'
that's not every language
well, lemme make another language real quick to piss everyone off
Nomid Íkorni-Sciurus
ClojureScript is also fro the web, but is that what you want?
Nomid Íkorni-Sciurus
languages for the WEB ?
Ludovic 'Archivist'
So tell me every language and their usecase
My advice is to learn half a dozen unrelated languages and work from there, you can learn on the go
Nomid Íkorni-Sciurus
I could say you can use ReasonML, OCaml, ClojureScript, TypeScript, JavaScript, Elm, D, C/C++, Assembly, AssemblyScript on the web
Nomid Íkorni-Sciurus
BUT it depends what you want to do
Void
Guys please help me

because j-i is < 0

I always make some dumb mistakes😓
Ludovic 'Archivist'
Also, I can't remember a single project I worked on where there was a single language used
i
(while I do think C++ is ultra-complex to me I also think that Rust even more complex to me lol)
apart from complexity, I am just thinkin what's the major application of them in 2022. Rust is a nice language though)

Easy implementation of some code although usually its iterative algorithm is better

Can "||" be used consecutively?Like a[i]=='A'||a[i]=='E'||a[i]=='I'……?

void gettotalprice(){
cout<<"price of butter";

int x;
x = amount*price;

here is small code. How to assign the int x value to totalprice? After last line?

Good afternoon, I'm sorry to bother you, these single-linked lists and their implementation, I do not understand them at all. Here are my attempts to implement the queue in this way, and I don't understand why there are so many errors all the time. I will be grateful for any help

Start and end should be Queue_el pointers not int and * is not used after new keyword

Good afternoon, I corrected what was pointed out to me(Thanks for the help and tips) , it really reduced the errors, but it still doesn't work(I just don't know what exactly is wrong with push and рор because I do as indicated in copybook)

printf("%x", ....
Can someone tell me the function of %x in c. I tried it for different numbers, work like %d till 9 and then it starts to give me some letter! Is a way to print out the to convert decimal numbers to hexadecimal number?

I also have another question; for printing out a character; I wrote %s and then put a & behind my variable, and onlinegdb printed my character without any warning, like this:
printf("%s", &ch);
But I'm confusing what happened. Is it the right way?

You forgot int before your main function and also in your second loop

This group is for C/C++ discussions only. Asking for help related to searching for mobile apps that teach you programming and worse still asking others to do the search for you counts as off topic. Go to the off topic group for such discussions.

How are you using it?
Void
int a[20];
scanf("%d",&a);
int i,j,k,len;
len=sizeof(a);
Void
I input {2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21} and the len is 80
Anonymous
int a[20];
scanf("%d",&a);
int i,j,k,len;
len=sizeof(a);
It should be sizeof(a)/sizeof(a[0])
Anonymous
I don't quite understand?
sizeof returns the size of the array in bytes. On your machine an int is 4 bytes long. So sizeof(a) returns 20×4=80. To get the number of elements, you should divide by sizeof(int) which is the same as sizeof(a[0])

Hi, i am struggling to choose between unity and unreal engine, i know that is a c++/c group, and this isn't a game development group ... but can i may ask (to someone that has tried unity or unreal or both) which shoud i choose ? shoud i start learning C# and go with Unity or learn c++ and go with UnrealEngine? :d

Thanks for the quick reply, i think i'll go with c++, one last question: learning c++ knowing js & py is that hard?
