MATLAB: How to naming files sequently

for loopfprintf

Hi all,
could anyone help me with this file naming (control loop)
TOTL_REDC_2017_07_ 02_0500
the bold part is fixed in all files, while the remaining part is different
02 corresponding to number of days (02, 03, 04, …, 29, 30, 31)
0500 corresponding to number of hours (0500, 0600, 0700, …, 2200, 2300, 0000(second day)… etc))
thank you for your help.

prefix = 'TOTL_REDC_2017_07';
ThisFileName = sprintf('%s_%02d_%04d', prefix, this_day_number, this_hour_number)
