For my use cases, yeah, I just want easy C interop in other langs

Stnby

Whats this?

Pavel

C > C++

false C++ is postincrement, so the values are equal, so the expression is false ;p

Anonymous

Whats this?

I thought there was gonna be some good ol arguments , so it's betteer to move to OT group 😅

Stnby

false C++ is postincrement, so the values are equal, so the expression is false ;p

They are not equal because C++ has the useless streams

Stnby

that people actually use

Anonymous

They are not equal because C++ has the useless streams

Lmao

Stnby

I am still surprised how it is possible to have C and C++ in the same place as both are very different languages

Stnby

I am fine with classes but whats up with streams :D

Anonymous

What else is useless in C++? Function overloading? Templates?

I am still surprised how it is possible to have C and C++ in the same place as both are very different languages

C and C++ are totally different

Anonymous

They even are not compatible

Pavel

I am still surprised how it is possible to have C and C++ in the same place as both are very different languages

As with everything related to C/C++, for historical reasons

Stnby

They even are not compatible

They are not compatible but very easy to port C to C++ but not the other way around

Diego

Word

Diego

I like C++ better when I need to work with C/C++ to build something, but for interop C is so much simpler

Anonymous

When you port normal C code to C++ without refactoring, you get shitty C++ code

Stnby

Also I find it way more easy to understand C as it doesn't hide things within constructors etc

Stnby

looking at complicated C++ code is painfully difficult for me

Some libraries are written in C++ but expose C interface For example — Intel Media SDK

Also there's an interesting project https://github.com/metacall/core

Diego

The only thing I find complicated about C++ is when it throws undefined reference to vtables when the functions are defined in the derived class, but other than that, just take your time reading about it lmao

Anonymous

There was C support Don't know if that part is still supported

for example imgui is an example of useless usage of C++ it has 1 class and is super difficult to get it working in C

Anonymous

Why would you want to use C++ library in C lol?

Diego

If it helps, you can try your hand at OOP in a simpler language like C#, and then expand on that knowledge with C++

Anonymous

How many years did you write code with C++?

Stnby

How many years did you write code with C++?

only in highschool

Stnby

after that I wrote only C

Anonymous

only in highschool

So, it's better to don't commenting.

Diego

You know you can write procedural code in C++ right It's not quite C but simple enough

Stnby

I used both and my preference is C although I like C++ as well

Hamid

oop is complex, it doesn't matter what language you choose

Diego

If you didn't give it a real chance then you have no business complaining about it

Anonymous

In C++ OOP is different

Stnby

It is hard to get used to completely different workflow coming from C

Anonymous

There's no CRTP in other languages, is there?

Diego

It does, actually The whole point of languages like C# and Java is to simplify everything OOP in C# is hella different from C++

As even if I know C++ syntax I still have C thinking

how to write Well structured C++ code

Use 1. Modern Effective C++ book (and other books from the same author) 2. C++ best practices on GitHub 3. C++ Core Guidelines 4. Conference talks by Kate Gregory, Jason Turner and others

Stnby

Thank you

Diego

I just read about it Isn't that similar to: C# public class SomeClass<T> where T : class { } public class SomeOtherClass : SomeClass<SomeOtherClass> { }

how to write Well structured C++ code

At first, you could do whatever you want to do. But for Well Structured C++ Code, you need some rules: - C++ Core Guide Line. - MISRA (For critical systems) - CERT (For sercurity notes) Also is really good to read the Effective C++ from Scott Mayer.

Templates in C++ and Generics in C# work very different And I don't know if this code would compile in C#

Diego

Oh it would I do it often

Diego

And yes, I know templates and generics are very different concepts

Diego

It even works if you constrain T to be SomeClass

Anonymous

It stimulates to type more

I think MISRA, CERT are more advanced and not always necessary It's better to start what I listed

And shoot in leg more

I actually used c++ in a c project just so i could use namespaces. That was a lot of extern C typing.

Anonymous

But damn, I can't handle a variety of functions right in the main namespace, so it was worth

Diego

https://dotnetfiddle.net/gAorGo I totally get that templates work differently, but I'd appreciate an explanation as to why this wouldn't serve a similar purpose, thank you!

How CRTP related to OOP?

How CRTP related to OOP?

It provides static polymorphism

It doesn't provide any kind of polymorphism
