The cron daemon usually sends the output of a program via mail to the owner submitting the job. Find out how to configure your cron daemon to do that, and/or consult with your system administrator how to modify your system setup to do this.

Alternatively, write debugging information from your program to a file so you can see how your program progresses and what values it finds, and where.
