Thanks, I just read on their site that private repos are very limited some time ago, so i was not sure if this changed

Does Codeberg allow private repos?

Zig is a modern C. Rust is a (modern) alternative to C++. So two different languages can exist alongside each other, just like C and C++.

Dynamic typing, special and unique syntax for every language feature, interpreter intrinsics

lIIl, IIIl, lIlI and IllI

I guess you ask for C++. There Type* can be null while Type& can’t be null. When it gets compiled Type& is compiled (mostly) to the same machinecode as Type*.
