未初始化的常量DrvierExam :: Console_Screen（NameError） - 需要帮助代码

Question

好吧，所以我创建了代码，当我尝试在Eclipse中运行脚本时，出现此错误 未初始化的常量DrvierExam :: Console_Screen（NameError）。 senerio为创建脚本是学生必须采取20个问题，他们将不得不获得75％通过这是15个问题。类名称需要有数组的正确答案，用于收集学生答案的问题和数组。

我想我在创建两个数组的写道上，但不知道，并在开始时得到错误。

$ class Screen 
    def cls 
    puts ("\n" * 10) 
    puts "\a" 
    end 

def pause 

end 
end 

class DrvierExam 
    def display_greeting  # This is a method 
    Console_Screen.cls  #Clears the Screen 

    print "\t\t Welcome To Georgia Department Driver Services" + "\n\nPress Enter to Continue" 

Console_Screen.pause

def display_instructions 
Console_Screen.cls 
puts "INSTRUCTIONS:\n\n" 

puts "You are starting DMV exam for your drivers licence" 
puts "You will be presented with multiple choice question," 
puts "Please type the letter of the correct choice" 
puts "Grades will be shown at the end" 
puts "Good Luck For the First Licence" 
print "Press Enter to Continue" 

Console_Screen.pause 
end 

def CorrectAnswer 
test = %w[1B 2D 3A 4A 5C 6B 7B 8A 9C 10D 11B 12C 13D 14D 15D 16C 17C 18B 19D 20A] #Array for real anwer

def disp_q(question, q_A, q_B, q_C, q_D, answer) 

loop do 

Console_Screen.cls  

puts question + "\n\n"

puts q_C 
puts q_D 

print "Type the letter representing your answer: " 
answer = []             
    reply = STDIN.gets 
    reply.chop! 

if answer == reply then 
    $noRight +=1 
end 

if reply == "a" or reply == "b" or reply == "c" or reply == "d" then 
    break 

    end 
    end

你指的是你的 “屏幕” 类为 “Console_Screen”。将所有引用更改为屏幕，并且它应该可以正常工作。
