#looping

#keep repeating something, with an end point otherwise will never stop!

command = " "

while command != "bye"
  puts command
  command = gets.chomp
end

puts "Come again soon!"

#what is wrong about this loop?

#Adding more logic to branching program

#version 1
puts "Hello, what\'s your name?"
name = gets.chomp
puts "Hello, #{name}."
if name == "Charlotte"
  puts "What a lovely name!"
else
  if name == "Felipe"
    puts "What a lovely name!"
  end
end

#DRY rule
#version 2
puts "Hello, what\'s your name?"
name = gets.chomp
puts "Hello #{name}."
if (name == "Charlotte" or name == "Felipe")
  puts "What a lovely name!"
end

#always good to use () when using the logical operators

#or means "one or the other, or both" - slight different
