Question

我在ruby中制作一个简单的测验程序，但我需要帮助来回答测验问题我对这整个红宝石的事情非常糟糕，但我会尝试解释，我希望程序在答案不是A，B，C或D时循环，但我也希望程序能够能够不在乎答案是A还是A或B或b以及其他什么，我已经得到常数A的语法错误是未定义的和意外的结局和东西。

require 'colorize'
require 'win32console'

puts "Hello! And Welcome the game that you shall name!".yellow  
puts "My name is Wuz and I shall be your guide for the time being!".yellow
print "Now young quester, what shall I call you?".yellow
call_you = gets.chomp
puts "Okay quester #{call_you} now we shall name the game!".yellow
print "Okay #{call_you} what shall the game be named?".yellow
named = gets.chomp
puts "#{call_you}! this game shall be called #{named}!".yellow
puts "I Will give you some instructions to begin the game and then I will be off as I have business to attend to in other parts of the internet!".yellow
puts "This is a simple text quiz game which will test your wits and other things!"
puts "To answer the questions in green all you must do is either input A,B,C or D or enter the correct word/number"
print "Ok?"
puts "Lets do a trial question!"

puts "What color is an orange?"

puts "A)Black"
puts "B)Red"
puts "C)Orange"
puts "D)Every colour!"
print "What shall you say?".red

say = gets
if
  say = A
  put "Wrong!".red
elsif
  say = B
  put "Wrong!".red
elsif
  say = C
  put "Right! Good job!".green
elsif
  say = D
  put "Wrong!".red
end

Answer 1

如果要包含大量文本，可以考虑添加更大的块在文本文件或Here documents中。这是后者的一个例子：

GREETING =<<_
puts "Hello! And Welcome the game that you shall name!".yellow  
puts "My name is Wuz and I shall be your guide for the time being!".yellow
_

INSTRUCTIONS =<<THE_END
I Will give you some instructions to begin the game and then I will be off as
I have business to attend to in other parts of the internet!
This is a simple text quiz game which will test your wits and other things!
To answer the questions in green all you must do is either input A,B,C or D
or enter the correct word/number.

Ok?
Let's do a trial question!

What color is an orange?

A) Black
B) Red
C) Orange
D) Every colour!
THE_END

我们现在可以在您的代码中使用这些常量：

puts GREETING

print "Now young quester, what shall I call you?"
call_you = gets.chomp

puts "Okay quester #{call_you} now we shall name the game!".
print "Okay #{call_you} what shall the game be named?"
named = gets.chomp

puts "#{call_you}! this game shall be called #{named}!"

puts INSTRUCTIONS

您可能希望在循环内提出问题，然后在给出有效答案时突破。在获得变量中的问题答案后，我使用case语句来处理响应。首先，我将响应转换为大写，以防输入小写字母。

如果答案为"C"（或"c"），则会打印"Right! Good job!"并退出循环。如果答案是“A”，“B”，“D”，则打印"Wrong!"并且循环存在。如果给出任何其他答案，则重复循环。

say = nil
loop do
  print "What shall you say? "
  say = gets.strip
  case say.upcase
  when "C"
    puts "Right! Good job!"
    break
  when "A", "B", "D"
    puts "Wrong!"
    break
  else
    puts "Invalid entry"
  end
end
puts "#{say} was entered"

第一行say = nil的唯一原因是初始化变量say，以便在块结束后检索其值。 say可以初始化为任何值。如果省略此语句，则say的范围仅限于块。

Answer 2

这里有很多问题。

if
say = A

指定变量A的值来表示并测试是否为真，而不是比较＆＃34; A＆＃34;的值。说。做我认为你想做的事应该是

if say.chomp == "A"
  puts ....

另外请清理结构... puts"blah"应该放置＆＃34; blah＆＃34;等等。

也许你可以把整个事情放在一个循环中：

wrong_answer = true

while wrong_answer do 
...
...
# for the correct response case
if say.chomp == "A" 
puts ....
wrong_answer = false
