I'm a new perl user. I was trying to print an array by using print @array and print "@array". Is it supposed to output the same thing? I got the different output. EX: @array=qw/v1 v2 v3/, the output for print @array will be v1v2v3 while it will be v1 v2 v3 in the other case. The difference is one is seperated by whitespace while the other is not. Could anyone explain why this happen? Thanks alot.
print @array; Is equivalent to: printf '%s%s', join( $,, @array ), $\; And: print "@array"; Is equivalent to: printf '%s%s', join( $,, join( $", @array ) ), $\; $ perl -e' my @array = qw/v1 v2 v3/; $, = "< >"; $" = ";-:"; $\ = "* \n"; print @array, "END"; print "@array", "END"; ' v1< >v2< >v3< >END* v1;-:v2;-:v3< >END* John -- Those people who think they know everything are a great annoyance to those of us who do. -- Isaac Asimov -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
