Fine, I'll assume that you missed all the posts which tell you to post what you tried, and that we don't give you free homework answers just because you've mastered "ctrl-c" and "ctrl-v".

Once you get round to the actual assignment you might want to look at using a stack or some other similiar datastructure thereof.

Why stack? Why "pointer implementation of the data structure"?
All you need: fgetc(f) to read a file char by char plus a level counter plus a simple logic:
search '/'...
if the next char is '*' then comment started, search '*' ...
and scan again...... and so on.
Start from a simplest scanner (without inner comments counter)...

>Why stack?
Why? Because it would probably be the simplest solution for finding matching pair comments, but then again there are many ways to skin a cat.

Since comments cannot be nested, a stack really is not necessary. A simple flag would suffice. Although a stack would be really helpful if you are looking for braces/parens/etc, things that can be nested.
