analyzer.rb cannot run.

[Genocide Law]

Hi, I'm kinda new to this programmin thing and I'm currently using
windows vista and it seems whenever I run this file:

line = File.readlines("text.txt")
lines_count = lines.size
text = lines.join
puts "#{line_count} lines"

It will show :

ruby C:/Users/administrator/analyzer.rb

*** WARNING *** Windows users should check the "Run process in terminal"
check box in the Debugger Preferences
to see STDOUT and STDERR output in real time.

C:/Users/administrator/analyzer.rb:2: undefined local variable or method
`lines' for main:Object (NameError)

exit

and as you can see, there's an error in the code but I can't seem to
find out what. I have attached the text maybe someone can run it and
tell me what's wrong?

Thanks,

Gen

The error message does tell you exactly the problem: it's on line 2 of
analyzer.rb, and the problem is that you referred to something called
"lines" but no such thing exists. That is, there is no local variable or
method called "lines"

On line 1 you created a local variable called "line", not "lines"

HTH,

Brian.

In this group, it usually means "hope that helps", or "hope that helped".

You can google internet acronyms to see some others in use. There's
also a wiktionary page dedicated to such a thing:
