Your problem is on gets which needs to be turned into gets.chomp (as already addressed earlier).

There are several ways to print lines into ruby. If you are more accustomed to 'C' or if you need more flexibility you can print using printf and sprintf[1]. Also you can use just 'p'. Take a look at the example below:

-------
GreyJewel:~ atma$ irb
1.9.2p320 :001 > array = %w( a b c d e f g )
 => ["a", "b", "c", "d", "e", "f", "g"] 
1.9.2p320 :002 > puts array
a
b
c
d
e
f
g
 => nil 
1.9.2p320 :003 > p array
["a", "b", "c", "d", "e", "f", "g"]
 => ["a", "b", "c", "d", "e", "f", "g"] 
1.9.2p320 :004 > printf("First letter:\t %s\n", array[0])
First letter:	 a
 => nil 
1.9.2p320 :005 > quit
GreyJewel:~ atma$

Note that using printf I was able to add a tab using '\t' and a new line using '\n'. Take a look at [2] for more info.

Happy rubying :-)
