general form of the phone number => three digits, followed by a -, followed by three digits, followed by a -, followed by four digits. 

\d matches a single digit.
{n} matches the previous match n times 
(e.g. \w{5} matches five word characters in a row)
- outside of [] matches a - 
(inside [], it specifies a range, e.g. [a-z] matches any lowercase alp
+habetic character.)

the rest is left as an exercise for the reader. Open book exam: perldoc perlre. Good luck, you have fifteen minutes! 

perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); 
+$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth
+er_name\n"'
