The requirements specify that:

The script is supposed to output the cleaned data to STDOUT. My question is, how do I report lines for a given file?

• Should I write to a separate report file for each type if there are any?
• Or should I write to STDERR?"

Hi Rayhan, For either program, but particularly the data-cleaning program, error messages should be printed on stderr, with all the real data going to stdout.
