#Here is the Input
Enter a number (999) to quit
1
2
3
4
999
#Actual Script
#!/usr/bin/perl
use strict;
use warnings;
sub add_nums {
# body...
# Add numbers entered at STDIN
print "Enter a number (999) to quit\n";
chomp(my $n = <>);
my $sum = 0;
while ($n != 999) {
$sum += $n;
chomp($n = <>);
}
print "The Sum is $sum\n";
}
add_nums;
#Output
The Sum is 10
The script basically adds all the numbers entered at STDIN until it encounters 999.
Two Questions:
1. Is Chomp here being used to chop the new line character after the while loop exists?
2. If so, why doesn't the while loop just exist after encountering 999 and print the result in $sum ?
Thanks.
