Hi,
If I run the below program from the command line using simply perl program.pl,
I get no compiler errors. If I put the file into EdSharp and press Control+F5
to compile, the compiler complains that I'm using uninitialized variables.
What's the difference?
Here's the program.
#!usr/bin/perl
# circle.pl
# Compute the circumference of a circle.
use warnings;
use strict;
my $pi = 3.141592654;
print 'Enter the radius:';
chomp (my $radius = <STDIN>);
my $circumference = 2 * $pi * $radius;
if ($circumference < 0) {
$circumference = 0;
}
print "\nThe circumference is $circumference\n";
Thanks.
Jim
