In Standard C and C++, your input facilities are text streams and
the parameters passed to the main() function. The output facilities
are text streams and the value returned from the main() function.
Anything else depends on the platform.
Some platforms provide "clipboards" for passing data between
programs. Others use sockets and pipes. Some even have memory
areas reserved for passing data between applications.
You will have to explore the facilities that are available on
your target platform(s).
