Ruby Ruby Objects and Classes Build a Bank Account Class Part 4: Printing the register

Right column won't align correctly

my file prints out something like this where the "Amount" and "60.00" are slightly off of where they should be


Description Amount
Beginning Balance 0.00
Paycheck 100.00

Groceries -40.00

Balance: 60.00

class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
    end

  def credit(description, amount)
    add_transaction(description, amount)
    end

  def debit(description, amount)
    add_transaction(description, -amount)
    end

  def add_transaction(description, amount)
    @transactions.push(description: description, amount: amount)
    end

  def balance
  balance = 0
    @transactions.each do |transaction|
      balance += transaction[:amount]
      end
    return balance
    end
  def to_s
    "Name: #{name}, Balance: #{sprintf("%0.2f", balance)}"
  end

def print_register
  puts "#{name}'s Bank Account"
  puts "-" * 40
  puts "Description".ljust(30) +"Amount".rjust(10)
  @transactions.each do |transaction|
    puts transaction[:description].ljust(30) + "\t" + sprintf("%0.2f", transaction[:amount]).rjust(10)
  end
  puts "-" * 40
  puts "Balance:".ljust(30) + sprintf("%0.2f", balance).rjust(10)
  puts "-" * 40
  end
end


bank_account = BankAccount.new("Jason")
bank_account.credit("Paycheck", 100)
bank_account.debit("Groceries", 40)
puts bank_account
puts "Register:"
bank_account.print_register

Hi Harrison Hondo, I'm not exactly sure what's happening on the line with:

"\t" + sprintf("%0.2f", transaction[:amount]).rjust(10)

It looks like that should work as it is. But I was able to fix what I believe is the issue you're having (the right justification doesn't include the part after the decimal point so the cents places stick out past "amount") just by changing it to rjust(8).

Hi Harrison,

I think you have to remove the tab caracter "\t" , your final should look like: :

puts transaction[:description].ljust(30) + sprintf("%0.2f", transaction[:amount]).rjust(10)
