Hi,
#!/usr/bin/perl
use strict;
use warnings;
sub add
{
$results = $_[0] + $_[1];
print "The result was: $results\n";
}
add(1,2)
$ ./subroutines_examples.pl
Global symbol "$results" requires explicit package name at
./subroutines_examples.pl line 8.
Global symbol "$results" requires explicit package name at
./subroutines_examples.pl line 9.
Execution of ./subroutines_examples.pl aborted due to compilation errors.
How to adjust the strict in this situations, why we use strict?
Thanks with best regards,
