Need help in understanding fprintf command and its application

fprintf( ’%8sVIII\n’, ’Henry’ )

fprintf( ’%-8sVIII\n’, ’Henry’ )

fprintf( ’%.3sVIII\n’, ’Henry’ )

Can someone help me with this? I cant figure out what the fprintf does. Especially the part before Henry in this. Please explain all three so I can use it properly.

To begin with, the quote syntax is wrong. This is correct:

fprintf( '%8sVIII\n', 'Henry' )

fprintf( '%-8sVIII\n', 'Henry' )

fprintf( '%.3sVIII\n', 'Henry' )

     HenryVIII
  Henry   VIII
  HenVIII

The first one right-justifies ‘Henry’ in the 8-character string field (the default behaviour), the second one left-justifies it (note the minus-sign in front of the 8), and the third one, with a 3-character string field, takes only the first three letters and right-justifies them.

See the documentation on format descriptors in the fprintf documentation for all the details.
