So you may never end up using C++

Dima

Then choose GoLang and Python

I don't like it

But good for what he is going to do

Which is the best Linux distro for coding / development ?

Vitaliy ◀️TriΔng3l▶️

WSL because you may have tools that look nice

Vitaliy ◀️TriΔng3l▶️

but seriously, possibly something Ubuntu/Debian-related because of lots of packages and lots of users who may help? though I think repos of other distros are pretty actively maintained as well

rinaigen

So, i have one question again. In 2 years, i'll have the thesis project, it is a some mobile game, i have to do it. Cuz of my choose depends on it.

rinaigen

I was browsing a lot of programmers profiles on github to search the best way, not to regret the time spent.

Thank you

So, Java + Python will be better for it? I want it for the future.

rinaigen

To be ready.

these two are meh. go for c++ or c# development. even Lua is better

Dima

Unreal Engine even allows you to make a game without writing a code.

Dima

Using Blueprints. But this is not related to C++ and is off topic

Dima

#ot

rinaigen

Okay, Thanks.

How can I get string from command ligne with using optstring

you don't. you get string from command line using argv

Anonymous

int main(int argc, char *argv[]) read from argv[0] to argv[argc - 1]

for more details see Jens Gustedt's book, it's free

Ok thank you

why does c++ need ide but html/javascript doesnt this question is making me sleepless pls make me sleep

Manas

why does c++ need ide but html/javascript doesnt this question is making me sleepless pls make me sleep

Who said so? c++ needs a compiler which the IDE provides along with the user interface its totally optional. You can write a program in any text editor and compile it with a compiler

Anonymous

how can i compile it outside an ide?

Manas

Install a compiler for c++ install gcc

Manas

are you using linux?

Anonymous

yes im using linux

Anonymous

i hv gcc installed

Manas

do u have g++ its better when it comes to cpp

Anonymous

yes i hv that too installed i had codeblocks so both the compilers are installed for c and c++

Manas

save your program in a file lets say code.cpp

Anonymous

ye oke then

Manas

then open your terminal in the programs directory and use the following command g++ code.cpp -o code this will compile the code and generate an output file with name code then just do ./code

Manas

the -o flag is used to specify a name for the output file it is optional

The size of a struct is always a multiple of the largest data type, what if there's an array inside it, let's say int arr[10], will the size still be the multiple of the the largest data-type?

Size of a struct is unknown

Since unaligned memory access is slow the C compiler pads for you

Anonymous

How the compiler pads is up to it

Ajay

Isn't the padding done so that the member with largest data-type is accessed in optimal way?

Anonymous

There are some CPUs that can't even tolerate unaligned memory access

Anonymous

It is all up to the compiler

Ajay

Is that only through the order in which we declare the data members inside the struct or there anything more to this?

the order does not mke a difference from what i know

Hi, what is a possible reason why std::hash returns back the value without any hashing?

Alex

hi. please provide the code and the output

Nils

hi. please provide the code and the output

In short: std::hash<std::bitset<sizeof(ulong)>> sHash; sHash(res);

Alex

I did not work with bitset, probably there is no reason to hash bitset, cause its already hash

Nils

On x86_64 it works fine but on aarch64 it doesn't...

On x86_64 it works fine but on aarch64 it doesn't...

Did u use the hash function from the standard STL library or of some other package such as boost asio

Đỗ

may be it need to recompile to get on well in aach64

Consider a grid of 1000 x 1000 LEDs which Initially are turned OFF. In this problem, you are allowed to pick any array of [5 x 5] of squares of LEDs and toggle their states. After toggling the states of all [5 x 5] squares one after one, how many LED will be turned ON?
