Welcome to the Monastery abcd

The first assignement seems easy; why check for every char with the dot and not just newline ? 

perl -E "say q(found ), $count=()=qq(abcdefab\ncdefa\nbcdef) =~ /a\n?b
+\n?c/gm, q( [abc] occurences)"

found 3 [abc] occurences

By other hand the description you gave of your code, does not make so much sense to me (and you probably missing use strict; and use warnings; ).

 while ($line=<inputfile>){chomp $line; $string=$string.$line;}

Infact what i understand is that you are accomulating every new line into $string and attempting the match for every generated string: so for a 100 lines file you are actually examining 5050 lines. this can be a problem.
