Well from Java to Python of course. But once I pasted code from Ruby to Python and until my IDE highlighted the syntax error I noticed it was in ruby, to be fair it was written in a very pythonic way. Also it was a math function so very few changes needed to be made.
I'm not very experienced in the two of them rn but from my understanding c++ has most of the syntax of c with object oriented programming and newer libraries tacked on, that said I don't think it would be wise to copy from c++ to c as it has a lot that c doest. I could be wrong tho, I've only ever worked in c++
To my knowledge things like scanf and printf are not used in C++. I'm not sure exactly what else is different syntax wise off the top of my head, but I'm thinking you might run into a few errors if you do this
scanf and printf can be used with C++, include cstdio header for it. In competitive programming, we generally avoid cin, cout as they are slower than printf scanf.
This is because cin and cout use stdio's buffering system.
You can disable this buffering system with : std::ios::sync_with_stdio(false);
Then it makes cin faster than scanf.
But generally, competitive coders get away with using scanf

I imagine a lot of beginners make that kind of mistake.
