Overview

How to use:

Fork and download this repo
run bundle install
run rspec - 4 tests should pass
Using a Ruby REPL you can use this programe:
- enter irb *require_relative 'lib/bank.rb' *require_relative 'lib/history.rb' *require_relative 'lib/print.rb'
- bank = Bank.new
- history = History.new
- printer = Printer.new
  
  => #<Bank:0x00007ff9e4189800 @account_history=[], @balance=0, @date_created="23/04/2018", @credit="", @debit="">
- Deposit $100: bank.deposit(100) => [{:date=>"23/04/2018", :credit=>100, :debit=>"", :balance=>100}]
- Withdraw $55: bank.withdraw(55) => [{:date=>"23/04/2018", :credit=>100, :debit=>"", :balance=>100}, {:date=>"23/04/2018", :credit=>"", :debit=>55, :balance=>45}]
- printer.print_all
```
date || credit || debit || balance
23/04/2018 || 100 ||  || 100
23/04/2018 ||  || 55 || 45
```
