Dear All,
I'm greatly overwhelmed by your quick help to my problem.
Here's the corrected code:
#!/usr/bin/perl -w
use strict;
# filename: reverse_string.pl
# editor: # VIM - Vi IMproved 6.1
# description: get user input and reverse input
print "Please enter any string, to quit press Ctrl-Z:\n";
#im at work right now :-)
chomp(my @input = <STDIN>);
my $total_elements = scalar(@input);
print "You have entered $total_elements arguments.\n";
print "They are: \n";
foreach(1..$total_elements){
print "\t\[$_\] my $input[$_ - 1 ]\n";
}
print "Press enter to see inputs in reverse order: ";
my $press = <STDIN>;
@input = reverse(@input);
print "The reverse -> @input \n";
Just a quickie. Why did scalar $input in the foreach loop
"works" without predeclaring it with my? I tried running both
and it runs as expected. No scoping required for this control
variable?
Thanks a lot. It sure is nice to learn when there are helpful
hands around. C yah.
