bash script. how to do output redirection with here documents

Question

I have a bash script where I am running a c program using here documents because the c program expects inputs from the user.

so i have something like this

#!/bin/bash
./runnable inputfile.txt <<_END_
2
4
3
4
3
3
2
_END_

now i want to send the output from the above command to some other file. just like we would do

ls > file.txt

is that possible?
