2_input_output_control.rb

# Prompt the user for a number, then read it in and print out "hi" that many times
#
# Repeat this process until the user submits "bye", then say "goodbye" and end the program
# HINT: Check out example 2 if you get stuck

# example:
# PROGRAM: Enter a number
# USER:    4
# PROGRAM: hi hi hi hi
# PROGRAM: Enter a number
# USER:    2
# PROGRAM: hi hi
# PROGRAM: Enter a number
# USER:    bye
# PROGRAM: goodbye


# remember you can try your program out with              $ ruby 2_input_output_control.rb
# and when you think it is correct, you can test it with  $ rake 2:2

def input
  puts "Enter your number or bye (if you wish to say goodbye)"
end

def hi_hi_goodbye
  # your code here
puts input
while (num = gets) && (num !~ /bye/)
    num.to_i.times {print "hi "}
puts input
end
  puts "goodbye"
end

#
# while line = gets
#   puts "You submitted #{line.inspect}"
#   break if line.chomp == 'exit'
# end
#
# puts "Goodbye!"
#

# This will just invoke the method if you run this program directly
# This way you can try it out by running "$ ruby 2_input_output_control.rb"
# but it will still work for our tests
