Is this a standard/normal/ok way to pass and use array by reference?
@alpha=("a","b","c");
@numer=(1,2,3);
#calling by reference
showIt([EMAIL PROTECTED], [EMAIL PROTECTED]);
sub showIt
{ my $a = $_[0]; #assinging by reference
my $b = $_[1];
print "a[0]:" . $$a[0] . "\n"; #accessing by reference
print "b[0]:" . $$b[0] . "\n";
}
Please let me know if there is anything wrong with this practice.
-thanks
