Conio.h is not a standard header file. That is why you can't use it everywhere. It was part of turbo c++ compiler which was used on dos os and it is 16 bit compiler. That means programs compiled from that compiler can't even run on 64 bit OS which we use nowadays. Using or learning it is completely useless and will not teach you any basics.

To clear screen you can use system("clear") which can be used in sololearn because it uses Linux to run programs.
On windows you can use system("cls")

And don't forget to include stdlib.h

Answer 2

conio.h is for DOS compilers and is basically depreciated at this point.
