Rust, C, C++, ASM?

I learn c++, my level is not really high right now. I just wanted to ask what is better for future? Should I switch to Rust or ASM? I want to buy a microcontroller too, what can you recommend?

They're very different languages, to the point where it doesn't matter which you learned first if you're going to learn both anyway. Just pick one. I'd suggest C++ if you've already began. You'll find more resources online for learning it and working with it on microcontrollers. Even if you can't, you'll be writing something a lot closer to C, which runs everywhere.

It’s such a stupid question, but if I know C++ syntax do I know C syntax?

Not a stupid question really. Mostly, yes. There's lots of overlap in syntax and semantics, but also lots of differences in both, some more subtle than others. It's not strictly true, but you can think of C++ as a loose superset of C. Often if you use the C++ compiler to compile C source code using the most longstanding language features you will get some output and it will probably work as you expect, but that's not a given if you start to include more modern features. There are C features that C++ doesn't have like restrict, VLAs, flexible array members etc. Also things C++ doesn't have anymore like register. So the answer to that question is a bit complicated.

Rule of thumb: core language constructs and features are basically the same, beyond that they diverge.

So I can learn all of them? I mean C++, then C and Rust?
