What would you like to do?
"Night at the movies!" exercise from codecademy. I think this exercise was really useful and helpful. I felt like a real developer for about 10 minutes :-)
movies = {traffic:4, babe:1, memento:2}
#movies = Hash[:traffic, 4, :babe, 1, :memento, 2]
puts "Welcome to your Movie Database!"
puts "---What would you like to do?"
puts "---To add a movie type 'add'"
puts "---To update a movie type 'update'"
puts "-- Type 'display' to display all movies."
puts "---To delete a movie type 'delete'"
choice = gets.chomp.downcase
case choice
when"add"
puts "Please enter the name of the movie:"
title = gets.chomp.downcase.to_sym
if movies[title].nil?
puts "Please enter the rating (1 to 5)"
rating = gets.chomp.to_i
movies[title] = rating
else
puts "That movie already exists!"
end
when "update"
puts "Please enter the name of the movie:"
title = gets.chomp.downcase.to_sym
if movies[title].nil?
puts "That movie doesn't exist!"
