Hello everyone,
Having been a Perl programmer for several years now I have become
accustom to using the following as my normal "start" of any Perl script:
#!/usr/bin/perl
use warnings;
use strict;
Randal Schwartz uses this:
#!/usr/bin/perl -w
use strict;
$|++;
Is there any difference between the -w and "use warnings" declaration?
I know that both turn on warnings and the -w is commonly used at the
command line, but was just curious as to if one was "better" than the other.
The posting a few weeks ago about "for" vs. "foreach" was interesting and got
me thinking about warnings.
One other item, Randal uses $|++; to "turn off the buffering for STDOUT".
What exactly is buffering of standard output?
Thanks,
Kevin
