Re: How can we interpolate an expression??

in reply to How can we interpolate an expression??

my $number = 5;
my $multiplier = 3;

# Use print instead of "say"

print "Product is ", $number * $multiplier, "\n";
__END__
Product is 15

"say" is a short hand way to add the "\n" at the end of the line.
when you don't mean or need that, just old fashioned print will work great.

Well, the only one different that I know between print and say is that: -

-->"say" adds a Newline to the output, whereas we have to give it explicitly in "print".

Is there any other different??

my $number = 5;
my $multiplier = 3;

# Use print instead of "say"

print "Product is ", $number * $multiplier, "\n";

#this does not work...
#"say" has limitations...

say "Product is ", $number * $multiplier;
__END__
Product is 15

"Say" will add a \n to a simple string. More complex things require "print" or "printf".
