• Alternatively, open irb and enter the following commands:

> bc = BankAccount.new

 => #<BankAccount:0x007fac528b0f78 @balance=0, @log=#<TransactionLog:0x007fac528b0f50 @transactions=[]>>

> bc.deposit("01/01/2012", 100)

> bc.withdraw("02/01/2012", 10)

Running tests

Specification

Requirements

• You should be able to interact with the your code via a REPL like IRB or the JavaScript console. (You don't need to implement a command line interface that takes input from STDIN.)
• Deposits, withdrawal.
• Account statement (date, amount, balance) printing.
• Data can be kept in memory (it doesn't need to be stored to a database or anything).
