Yes, it can be done, every compiler I know of lets you do this.

Look at the pre-processor directive -
'#include <thing>'
or
'#include "file"'

Look up the use of "header file".

Almost every open-source CPP application/library will have lots of
examples of how to define interfaces in header files and separate the
code into a library or multiple files.
