Talk to another program

[Jeff]

How do i make a program in C, i have Visual C++, DJGPP, and Turbo C++ 3.0, that sends input to another program that is running waiting for the user to enter something through the keyboard. Thanks for any help you can give. I am using windows 98 if that helps.

I can think of a few ways, the easiest being a temporary text file.
