Input and Output from another App

[microcacti]

Hi

How am I able to provide inputs and get output from another program I wrote in C++. For example, I have a program I wrote, and I need to test its output against a already generated outputs. It uses cin and cout. Please advice, I would really appreciate it.

Thanks

You should use some form of IPC (interprocess communication) such as sockets or pipes. Another way to communicate between processes is by using a file that one process updates and another process reads. You will need to use locks of course.
