Hi All,
I am new to perl and while going through the chapters of Learning perl,
i just came through one excessive, while i was able to complete it, i
just came across something that didn't work and i couldn't find any
explanation for it. Would be great if i get some help in understanding
this behavior.
A few comments on your code:
below is the code
print "the string: ";
$string = <STDIN>;
print "the no.: ";
chomp($number = <STDIN>);
$result = $string x $number;
print "the result is:\n$result";
1. Add "use strict" and "use warnings".
2. Declare all variables using "my".
For more see:

Regards,

in the above code when i use
$result = $string x $number;
i get the right result, i.e. strings printed on two lines.
but, when i use
$result = $number x $string;
I don't get any output at all, just wondering why this happens, any help
would be highly appreciable.
Regards,
Omps
Thanks for the response, using the
use strict;
use warnings;
did gave me something like
Argument "om\n" isn't numeric in repeat (x) at learning.pl line 51,
<STDIN> line 2.
so i believe the x operator wants the number as the second variable.

omps.
