Question

我已经创建了一个ATM程序，并希望重写它的某些方面需要两个文件，一个包含帐户上的名称和货币信息，另一个包含引脚号信息，这里是工作的当前代码ATM：

class Account
  attr_reader :name, :checking_account, :savings_account, :transfer
  def initialize(name, checking_account, savings_account)
    @name = name
    @checking_account = checking_account
    @savings_account = savings_account
    @transfer = transfer
  end


  def pin
      @pin = '1234'
  end


  def display
    puts "Welcome back #{name} enter your PIN:"
    input = gets.chomp
    if input == pin
      main_menu
    else
      bad_pin
  end
end


def main_menu
  puts """
  Welcome back #{name}!
  Follow the instructions as follows:
  To display Balance press '1'
  To make a Withdrawl press '2'
  To make a Deposit press '3'
  To Transfer funds press '4'
  To exit the system press '5'
  """
  input = gets.chomp
  case input
  when '1'
    balance
  when '2'
    withdrawl
  when '3'
    deposit
  when '4'
    transfer
  else
    exit
  end
end


def balance
  puts "Which balance? Checking or Savings?"
  input = gets.chomp
  if input =~ /checking/i
    puts "Your balance for your Checking Account is: $#{checking_account}."
    main_menu
  elsif input =~ /savings/i
    puts "Your balance for your Savings Account is: $#{savings_account}."
    main_menu
  else
    main_menu
  end
end


def withdrawl
  puts "Please press '1' to make a withdrawl from checking. Press '2' to make a withdrawl from Savings. Press '3' to go back to the menu."
  input = gets.chomp
  case input
  when '1'
    puts "How much would you like to withdrawl?"
    input = gets.chomp!
    @checking_account -= input.to_f
    puts "You have withdrawn $#{input}; you now have $#{checking_account} in your checking. Thank you for using this ATM you will be redirected to the main menu."
    main_menu
  when '2'
    puts "How much would you like to withdraw?"
    input = gets.chomp!
    @savings_account -= input.to_f
    puts "You have withdrawn ${input}; you now have $#{savings_account} in your savings. Thank you for using this ATM you will be redirected to the main menu"
    main_menu
  else
    main_menu
  end
end


def deposit
  puts "Which account would you like to deposit into: Checkings(1), or Savings(2)?"
  input = gets.chomp
  if input == '1'
    puts "Enter amount to deposit: "
    amount = gets.chomp!
    @checking_account += amount.to_f
    puts "You have made a depost of $#{amount} leaving you with $#{checking_account}. Thank you for using this ATM. You will be redirected to the main menu."
    main_menu
  elsif input == '2'
    puts "Enter amount to deposit: "
    amount = gets.chomp!
    @savings_account += amount.to_f
    puts "You have made a deposit of $#{amount} leaving you with $#{savings_account}. Thank you for using this ATM. You will be redirected to the main menu."
    main_menu
  else
    main_menu
  end
end


def transfer 
  puts "Would you like to transfer funds from Checking(1) or Savings(2)?"
  input = gets.chomp
  if input == '1'
    puts "Enter amount to transfer from Checking to Savings: Current balance #{checking_account}."
    amount = gets.chomp
    @checking_account -= amount.to_f
    @savings_account += amount.to_f
    puts "You have successfully transfered #{amount} from your Checking account new balance: #{checking_account}. Savings balance: #{savings_account}. You will be redirected to the main menu."
    main_menu
  elsif input == '2'
    puts "Enter amount to transfer from Savings to Checking: Current balance #{savings_account}."
    amount = gets.chomp
    @savings_account -= amount.to_f
    @checking_account += amount.to_f
    puts "You have succesfully transfered #{amount} from your Savings account new balance: #{savings_account}. Checking account balance: #{checking_account}. You will be redirected to the main menu."
    main_menu
  else
    puts "Invalid entry"
    exit
  end
end


def bad_pin
  puts "Access Denied: incorrect PIN"
    exit
  end
end

my_account = Account.new("Thomas", 500_000, 750_000)
my_account.display

我想要做的是使用两个单独的文件，names.text和pins.text一个保存帐户名和帐户信息（names.txt），另一个保存帐户的密码（ pins.txt）。

names.text I.E。：

my_account = Account.new("Thomas", 500_000, 750_000)
my_account.display

my_account2 = Account.new("Jake", 50_000, 50_000)    
my_account.display

my_account3 = Account.new("Anothername", 10, 50)
my_account.display

带有引脚号（pins.txt）的文件我认为看起来像这样（如果不是请赐教）：

my_account @pin = 1234
my_account2 @pin = 2345
my_account3 @pin = 3456

所以我的问题是：

除了显而易见的pin方法之外，我还需要在哪里重写此代码才能从文件中获取信息。
我是否需要使用require或require_relative？

重写ATM程序需要两个文件
