<conio.h> and its functions clrscr() and getch() are not standard functions and therefore it is not mandatory for compilers to support them. In fact, it is mainly old (and outdated) compilers like Turbo C++ which do so. Same for <iostream.h>; modern C++ uses <iostream> as header.

that sounds really awful man, turbo c++ is old and nobody uses it on jobs anymore. the college you're attending should really update their c++ lessons.
and the conio.h header file won't work on sololearn so i would suggest downloading a turbo c++ compiler if you really need it.
