Ruby Tips [Iteration]

I am sure you will be Jaw dropping after looking at this code.

How many lines will it take in Ruby to print your name ‘n’ number of times?

The answer is 1 line. Oh.. is that so….!!! can you show me how it is? Yes here it is.

10.times { puts “Your_name\n” }

save this file as filename.rb and run from terminal like ” ruby filename.rb “. Oooo.. its great…. am wondered..

In the similar way if you want to print numbers from 1 to 100 or any range try this:


100.times { puts (i=i+1).to_s + “\n” }

just two lines.. very simple
