You can catch the errros by using eval function.
Keep your code in eval block some thing like shown below.
Eg.,
#################################
eval {
my $a = 0;
my $b = $a/0; #Dividing 0 with 0 is definitely an error
};

if ($@) {
print "\n Error in your code";
}


############################
-> Eval block always ends with a semi-colon. $@ will catch
the errors persent.

-> If any errors are present $@ will be set otherwise $@
will not be set

-> Unfortunately in Perl we don't have Explicit Error
handling techniques like some other languages like java etc
I mean like IOException etc.,
