Sad to say, compared with in printf, You can not source the sector with to be a operate time argument:

All the examples provided underneath use arrays which has not been taught nonetheless, so I am assuming I am unable to use %s yet either.

* Brings about fprintf to pad the output right up until it's n characters broad, where n is definitely an integer worth saved from the a perform argument just preceding that represented because of the modified sort.

And since your second parameter is vacant string "", there is no distinction between the output of two scenarios.
