File operations in Ruby

File concepts in Ruby This Ruby program opens file in write mode and writes text in it. Then opens the program in read mode and reads the contents. Code:

File.open('test.txt','w') do |f1|
  f1.puts "Welcome to LivetoLearn.in"
  f1.puts "Thank you! Visit Again"
end
File.open('test.txt','r') do |f2|
  while line=f2.gets
    puts line
  end
end

Output:

Welcome to LivetoLearn.in
Thank you! Visit Again
