The plot thickens! I can get it to work if I have a data in the array, such as my
script below:
print "Here are your friends: ";
@friends = qw (Sam Joe Sally);
print "@friends\n";
print "I know $friends[1]";
I still can't grab the element of an array that requests user input though.

Hi Anthony,
grabbed this from O'Reilly's Learning Perl :
@rocks = qw/ bedrock slate lava /;
foreach $rock (@rocks) {
$rock = "\t$rock"; # put a tab in front of each element
of
@rocks
$rock .= "\n"; # put a newline on the end of each
}
print "The rocks are:\n", @rocks; # Each one is indented, on its own
line
Still learning how to grab input from user via chomp, but this should
help
you work out how to print out all entries in an array using the foreach
thingy :o)

Subject: Array Question
Hi! I'm still wallowing in Chapter 3 (Arrays. Why can't I get it?!?!?!?
ARGH!!!!!) of Learning Perl on Win32 Systems. I'm trying to create an
exercise but I'm not getting the results that I want. Here's what I'm
trying
to do:
I'm asking for a list of names:
print "Name your friends: ";
@names = <STDIN>;
Then I want to pretend that I know the one of the friends. In this
case,
I'll choose the 2nd one and here's where I'm not getting what I want:
print "I know $names[1].\n";
The output shows "I know ."
Isn't "$names[whatever]" what I'm supposed to use to get an element of
the
array? I've tried this with numbers and have gotten the same results.
What
am I doing wrong? Thanks! :-)
