Hi everyone I have a question I want to take a long string as an input and then split it according to spaces The length of string is not clear Any idea ?

You can store really huge string in memory if you need (depends on available RAM) if string is bigger than gigabates so you have to split it and work with parts of input string.

where is the mistake

The mistake is your indentation is so bad

How i can the code source code then

Hello first of all. I'm using Vs code and msys2 mingw to code in C++. I can't install wxWidgets. I need help. Can someone with knowledge help?

I am eating code in java. Now I need to create a virtual camera in c ++, I found a way, but I don’t know how to connect mfvirtualcamera.h. Can anyone explain how this can be done for the project is very important

what build system? and OS is windows i assume?

or build system generator in case of cmake

like how do you build your program 😅

what build system? and OS is windows i assume?

Windows.

using cmake?

nmake?

just the compiler directly? 😅

I'm trying to compile with g++ but it won't compile

yep, you need to tell the compiler where the includes are and also tell the linker to link against wx. That usually happens in the build system. On windows I don't know how to install libraries easily though. I would probably go with FetchContent in cmake, that will allow you to automatically download the library. Im sure you can even find examples online

Guys how to send github link ?

probably not allowed 😅

as seen here

probably not allowed 😅

Sad then how to send source code

Someone send me link where I can download c++ compiler

Also the source code is huge

I got a serious problem in implementing vs code for coding c, I tried every way in google but I always get errors coding with vs code, dont you know of a good link to teach how to ?

Guys how to send github link ?

You can send a GitHub link. But new users are restricted from sending links for a day to prevent spam. Moreover, I am not sure if anyone will go through the process of debugging your code for you. If an assertion fails, the assertion would say why it failed. Can't you take it from there?

It's doesn't say why

It's just say Failed nothing else

It's just say Failed nothing else

It is failing because init_heavy is set to false and it is expected to be true after calling init_heavy_tlb function. Now go and figure out why that is the case

Guys, a serious framework to develop a commercial 2d game? Lowlevel if possible, with commercial games made with it? I am already evaluating Raylib, Unreal, smfl2 etc . If anyone have experience developing 2d games will be appreciated. Thanks

I dont have much 2d experience, but i searched for 2d in my stars on github. So checkout all on github: godotengine / godot, erincatto / box2d, urho3d / urho3d , opentoonz / opentoonz , cocos / cocos-engine , nCine / nCine , fishfolk / jumpy (more like example of 2d game), NoelFB / blah , diegomacario / Dyna-Kinematics , jhasse / jngl .

Hey Does anyone know any website to learn cpp?

Thank so much for your rich answer. I used Godot to develop a game already, for 2 years, i can say its a very good engine but you have to enter in their particular philosophy made of stage/objects (similar to flash) wich can be confusing. Actually i am moving to what so far i can say are the best for 2d games: raylib,sdl, smfl. If somebody knows something better please tell me. Thanks

I want to extend this class and provide the ability to get new information using the same fashion. However, I'm stuck with a linking time error.

Hi

Why is my message being deleted? I doesn’t have any links

Can you please help me understand how to work with std::move()? I’ve included a JSON lib in my project. The typical usage is to call it like this: JSON myjson = JSON::Load( "[ { \"Key\" : \"Value\" }, false ]" ); Now I want to return the myjson object from a function. How would I do it? By simply return myjson?

Worked this time...

The lib I am using is called SimpleJSON, from NotAPenguin0 on github, include/include/json.hpp line 646

Hi. Who can help with bit operations?

I need to convert an array of int8_t to int32_t using no functions. I have been suffering for a long time, but it does not work. I have numbers (-120, -127,0,0) and I know that the answer should be 33160, but when I try to do a bitwise shift, it turns out some kind of nonsense

beware of the fact that you are working with signed types

there are probably multiple problems, one of them might be the fact that you are ORing an uninitialized variable

another one that data[i] >> 8 is probably 0

Depends on how the class JSON is implemented. You have to check it's header file to see if it supports move operations. If it doesn't, returning it by value is the best option. You can then expect compiler optimisations like NRVO to kick in which would make it less costly.

The problem is that the template specialization is in an entirely different namespace. Your compiler can't figure out where to find this template specialization based on the class or the arguments. So the compiler won't know that it has to search in the namespace spec for the specialization. It will just assume that it will be provided in another object file. This is the reason why you are getting the linker error. Typically there is no workaround unless you are willing to hack around a bit which would make your code ugly. My question would then be "Why do I want to do this"? If extending the original namespace is not a choice, then that should be a clear indication that the author of the class does not wish for his class to be extended the way you think it should be

json is just a javascript object notation => the way you write object in javascript

Can anyone tell me which is better between Cocos and Unity... And why? 😢

Can anyone tell me which is better between Cocos and Unity... And why? 😢

not that this is related to c/c++ (be sure to read the rules), but Unity is more popular than cocos, so if you are choosing between those two and you don't see any pros and cons, you can choose unity

I've passed some steps with do while, but I got stuck, how is it exactly?

do{ }while(input < 1 or input > 3)

Better at what?

Yes, it is possible in telegram supergroups to enable sending photos. (although we have decided to turn sending photos and videos off for this group)

I know it's possible, I meant you enable it, because photos can make points far better.

Hm..Easy to create a game and which is lighter...

do{ }while(input < 1 or input > 3)

Bro, Tnx for reviewing do while syntax, but I'm looking for how to. And I'm wondering it's banned to send photos to express the problem clearly.

I used unity and it's really heavy
