Answer 1

SoloLearn doesn't have all features.
The unsatisfying best solution: Uncomment parts of your code and try if it compiles so that you see where exactly the error is.

Answer 2

No, there are strange invisible characters. And you have some of them in your code.

Answer 3

Oops!
Ok Timon Paßlick you was right.
