how about:

C:\family\ruby>type a1.rb

array = []

array[0] = "car"
array[1] = "bike"
array[2] = "motorcicle"

#p array

str = "Today I went to school by car. I saw a bike............ "

array.each {|word| str.gsub!(word,"*") }

p str

C:\family\ruby>ruby a1.rb
"Today I went to school by *. I saw a *............ "
