You can use popen() to send it the input through a pipe, with the
result going to a file you read later. Or you can put the input in a
file, and use popen() to read the result. You can't use popen() to
get a pipe for both input and output.
To use a pipe for both input and output, you have to do something much
more complicated, such as using pipe(), fork(), and exec() to set up
the process, and select() to handle the reading and writing. It's
not worth the trouble in most cases.
