Hi I was hoping that anyone could help me with this piece of code from
my program?! I have a menu with 2 submenus that you can reach from the
main menu. When I start the program I want the main menu to be presented
with a number of choices. My program is based on user input so naturally
when you enter the program you should be able to do the choices that are
presented in the menus. It worked before but now when I started adding
features for it(its for an assignment for a course) now it just presents
the menu and then exits the program. Can anyone help me with this. I
will post the code below and hopefully someone with more programming
skills than me can see the problem. Thanks!
module Menus
def self.getValidNumber
input = gets.chomp
while input > @options.size || input < 1 do
puts "cant do that try again."
input = gets.chomp
end
number = input.to_f
if (number <= 0)
puts "cant state a negative value."
getValidPositiveNumber
end
return number
end
def self.get_valid_input(options)
input = gets.chomp
while (!options.include?(input) && !options.include?(input.to_i))
puts "No good, you have to choose a value between " +
valid_options.inspect
input = gets.chomp
end
return input
end
class Menu
attr_reader :options
# Pass in array of options
def initialize(options)
@options = options
end
def main_menu
puts "---------------------------"
puts " Main Menu"
@options.each_with_index do |item, i|
puts " #{i+1}. #{item}"
end
puts
puts "What do you want to do?"
end
def self.make_choice(choice)
# chooses something from the menu based on the choice
case choice
when 1
check_in

exit
end
end

@options.each_with_index do |item, i|
puts " #{i+1}. #{item}"
end

end
end
m = Menus::Menu.new [“Checkin”, “Checkout”,“Lists”,“Economy”,“Exit”]

if Menus == 3 then m = Menus::Menu.new [“List current guests”,“List all
guests”,“back to main menu”]
m.lists_menu
elsif Menus == 4 then m = Menus::Menu.new [“Price list”,“Edit price
list”,“back to main menu”]
