Reading stdin from stdout of another application

Hi all. I am trying to set up a C++ program which will continuously
read stdin from another applications stdout. I will continue reading
until I read a message that will indicate to stop. Does anyone have
any ideas on how I can do this?

Thanks for responses.

AFAIK, only the OS can control where stdin comes from.

In MS-DOS or Unix (don't know about other platforms), use a pipe

qwert | yuiop

will run qwert, the stdout of which becomes the stdin of yuiop.
