A simple "if else" is enough to handle the option. But there will be more options added, e.g. "--data-page-size", which also impact the output format and sort order. The code will become too complex to be maintained. Divide the big printf into several small pieces. Output the specific piece only if the related option is applied. Divide the big sort order string into several small pieces as well. Appends specific sort string only if the related option is applied. No functional change.
