Just output to stdout, and then run your program with stdout redirected to a file.

for example, with tcsh: > ./my_program >& my_program_output

what should the file be? and how will i read from file?

The output file will be a text file. (If it exists, it will be overwritten).

Aren't you supposed to submit the output file?

To see what it contains, > cat my_program_output (or its equivalent on your platform)

See: http://www.tutorialspoint.com/unix/unix-io-redirections.htm

yes, i should submit the output file, but i should download the input file,run on my computer, then submit the output file

So write your program to read from stdin, and redirect stdin to read from the downloaded input file.

> ./my_program < downloaded_input_file >& my_program_output

where should i write this?
