In programming c without main function program execution is it possible
No
There is a hidden procedure called _start that will call main()
_start is where the real execution of the program starts
If it cannot find main(), it's an error

On MCUs even this is in your hand (startup code) so yes it is 😁 but don sin like that please

A program without main() is called a library
It's something you will see a lot when you advance in the language
A library is a code that other codes uses it

Well I'm not that familiar with Embedded system
But in general it's a good to keep it simple for beginners

https://stackoverflow.com/a/29694958 hoho it is worth of trying even on desktop. Wondering if opening of stdout and writing stack alocated strimg requites any initialization

Look at the link i posted

Which will ve loaded first before the program execute

I think it's coming from C runtime
global _start
Section .data
Section .text
_start:
_exit:
mov eax, 0x01
mov ebx, 0x00
int 0x80

Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is.
These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot?
If you have a question ask it directly. You are more likely to get a response that way.

Should we ban you for not reading the rules then?

Because if you can't find the resource section, it can only mean you did not read the rules

There is a possibility to change it. But I think it is not worth doing. See documentation gnu

Awkwardly this compiles
consteval double foo()
{
const double a = 1.0;
return a;
}
int main()
{
constexpr double f = foo();
}
but this does not
int main()
{
const double f = foo();
static_assert(f == 1.0);
}
this compiles
int main()
{
const int a = 1;
static_assert(a == 1);
}
const variables can be evaluated at compile-time only if the type is integral.

Not gonna lie, the use of pointers where they are completely pointless is disgusting me too much. Look into shared pointer, it will make your code more correct which will be much better

Hi everyone, what career path in c++ is more in demand
This is very vague, there are a great many career paths for a C++ dev, from fintech, gamedev, VFX, embedded, database engineering, operating systems, machine learning, library development for other languages, web, networking, and those are only the ones that I have actually done

Drogon for web or networked stuff, often with a variant of postgres, unreal engine, a bunch of low level libs I made for embedded, a lot of raw C++ actually, I tend to shy away from frameworks where possible

it is very easy most of the time
Ludovic 'Archivist'
Oh i didn't even think it was possible
https://git.nekoit.xyz/Archivist/mct20/src/branch/master
This generates a C++ hashmap with binding to use with C types

It was made in a couple of hours, and is not as well tested as it could, but it should work

Which one? If you're talking about the class layout, that's not by me. It's leetcode.
Btw, I was using static and that was causing the problem as this function was being called multiple times by the online judge.
And also, I'm new to graphs as I'm in first sem of college, so my code may seem messy... Sorry

But those Questions are criteria for us newbies.
