why would you want to do this? In principal, yes you could do this but
it very platform specific. You'd need to go to a platform specific
group
(Win32 or Unix etc.) access the file system. Or write your own file
system (not to be recomended as a first programming excercise! :-)

There are already standard functions rename() and remove() that
will rename and delete files.

Or write it in terms of rename() [is that standard C? if not, you could
copy and delete] and remove().

Normally you would implement these functions by calling platform-specific
code provided by the creators of the operating system.
If you want to build a file system yourself it is very difficult. You have
to know how files are laid out on disk, and how to address the disk
controller at a low level to mark files as deleted, change the name, and so
on.
