Answer 1

you can use the printf function but you used windows.h and conio.h , that's not supported here .

and moreover don't write ".h" here
use
#include<cstdlib>

Answer 2

SoloLearn doesn't support a lot of libraries. It is only meant to teach the beginnings of a language. You can use the full syntax of the language, but only the libraries they choose to support.
