[ because I would love to see other solutions to this, I posted. ]

This sounds suspiciously like someone's homework assignment.  In fact,
I had exactly such a homework assignment, and this resulted :-)

The following lines are a lex program to recognize c comments, not nested. 
This does NOT take into account any quote marks within a comment; i.e., 
quote marks don't 'escape' the close comment marker.

I compile this via "lex ccom.l ; cc lex.yy.c -o ccom -ll"

----snip----
   /* this is a regular expression to match a c comment	*/
   /* written by cml 890922   (probably not minimal)	*/
%%
"/*"([^*]|[*]*[^*/])*[*]+"/"	{printf("saw a c comment.\n");}
.				{putchar(*yytext);}
