How to know in VSCode

Do you have a std=c++17 flag in your build?

Can I use void* safe?

Can I use void* safe?

Why would you? You have templates, variant, any - etc.

You can easily bust your leg off 😁

a pointer for anything Why not use? I want to use variant but variant is too large

a pointer for anything Why not use? I want to use variant but variant is too large

My variant length is 96 Byte

What's your class size that you put into the variant?

Dynamic classes like boost cpp int boost dec float and std::string

My variant length is 96 Byte

My variant length is 96 Byte

What software are you working on that it makes a difference?

Your pointer is 64 bit, even if variants adds 32 bits in exchange for type safety - I'd go with type safety every time. How many variants do you want expect? Billions?

Using pointers for each classes is much better in my class Like using pointers for these three classes it will take 8*3=24 bytes and i can delete pointers or ... To get free memory

Memory has to be allocated anyway

And mallocing each thing is worse than having extra on the stack

But using much memory isn't good at all

And imagine how much var in python are in use

Pointer + object that it points to will consume more memory

It doesn't make sense unless you're doing an interpreter

But I want to use this cpp_int* i=0; cpp_float* f=0; std::string* str=0; In this case I can just use one pointer and delete all others have So better in size

What to do now?

I think for someone who doesn't know what C++ standard they use and the size of problem domain (many many variables is not well defined) you're concerning yourself with wrong issues. Implement something that works optimise for every last bit later if needed. Algorithms that you use will have much greater impact than difference in size between pointers and variants.

Hi, friends hope you're having a great day! I am working on an app where I am using socker.io and express module in the backend. But now I want to use rest API for some scenario and syn it with socket.io for example: Suppose if a client name Tom wants to join a chat room, So Tom sends a request using the rest API route "domainName/joinroom" and the server gets that request now the server will first validate the request and then join the room. However, in order to join the room, the server needs the socket object that can connect Tom to the chat room. In order to get that specific socket object, the request must send using socket.io and I am trying to avoid that. if you guys faced the same situation, please comment a reference code or send a link related to this problem.

Thx for your suggestion Do you know where the files will be saved in this IDE? I used ofstream command but I don't Know whether the file is created or not

Don't you have a pc? Coding on a phone is a torture.

Neeeh it's fine here just disable the autocaps hahaha

Where is "here"?

Here is my phone xD

You have a tiny screen, no proper keyboard, no proper multitasking and you have to hold your phone all the time. No, it's not fine. Any crappy PC, as long as it can run a modern desktop OS and have several GB of ram to spare for coding is better. It doesn't have to be latest and greatest model to beat a phone experience
