Question

我在Ruby中真的很新。

所以我确实在循环中创建了一个菜单，将我发送到＆＃34; start.menu_one＆＃34;但是我可以在＆＃34; def menu_one＆＃34;中进行另一个循环。这可以把我送到＆＃34; def menu_three＆＃34;

问题是我无法运行代码？你们中的任何人都知道问题是什么，因为我无法找到它。

file = File.new(".txt", "a")


class Start

  def menu_one 

    while (select !=2)  
    puts "Press 1 to make a new test"
    puts "Press 2 to search after test results"
    if (select == 1)
      start.menu_three
      break
    elsif (select == 2) # its here the problem is? 
    end

  def menu_two
    puts "Press 1 to see the overview of the tests"
  end
end

  def menu_three
    puts "hej"
  end
end 

  start = Start.new
  require 'io/console'
  select = 0


  puts "Welcome to the multiple choice test"

  while (select !=3)
    puts "Press 1 to login as admin"
      puts "\n"
    puts "Press 2 to login as student"
      puts "\n"
    puts "Press 3 to exit "
      puts "\n"
    select = STDIN.getch.to_i 

    if (select == 1)
    start.menu_one
    break

  elsif (select == 2)

    start.menu_two
    break 

  elsif (select == 3)
    puts "You have now exited the program"
    abort
  end

end 
end

class Start

  def menu_one 

    while (select !=2)  
    puts "Press 1 to make a new test"
    puts "Press 2 to search after test results"
    if (select == 1)
      start.menu_three
      break
    elsif (select == 2) # its here the problem is? 
    end

  def menu_two
    puts "Press 1 to see the overview of the tests"
  end
end

  def menu_three
    puts "hej"
  end
end 

  start = Start.new
  require 'io/console'
  select = 0


  puts "Welcome to the multiple choice test"

  while (select !=3)
    puts "Press 1 to login as admin"
      puts "\n"
    puts "Press 2 to login as student"
      puts "\n"
    puts "Press 3 to exit "
      puts "\n"
    select = STDIN.getch.to_i 

    if (select == 1)
    start.menu_one
    break

  elsif (select == 2)

    start.menu_two
    break 

  elsif (select == 3)
    puts "You have now exited the program"
    abort
  end

end 
end
