newline issue

grashopr has asked for the wisdom of the Perl Monks concerning the following question:

Whenever I execute the following...

print "Currency converter\n\nPlease enter the exchange rate: ";
my $yen = <STDIN>;

print "Please enter first price to convert";
my $price1 = <STDIN>;
print $price1, "Yen is ", ($price1/$yen), " pounds\n";

I get...

Currency converter

Please enter the exchange rate: 100
Please enter first price to convert 100
100
Yen is 1 pounds

I can't figure out why there is a new line created 
on line 6 after print and before $price1?

Thanks,

-John

I can't figure out why there is a new line created You think you entered "100", but you in fact entered "100\n". (Hitting the "Enter" button does that.) Just `chomp $price1;` straight after <STDIN> has been assigned to it and the newline will be removed. Cheers, Rob	[reply] [d/l]

BTW, you should also chomp $yen. `chomp $yen;` [download] for more details, see chomp	[reply] [d/l]

You can figure it out if you examine your data by ddumpering^{Basic debugging checklist} to visualize your data (lesson courtesy of Basic debugging checklist and brian's Guide to Solving Any Perl Problem )	[reply]

chomp worked perfectly! Thanks all. I feel it's a little of a cheat since we haven't learned chomp yet in the course I'm taking. But I'm glad it works. Learned something new! On to the next challenge!	[reply]
