Approach

I decided to start by developing the deposit function,

• increasing the balance by a given amount
• storing the amount increased by
• storing the balance after deposit
• storing the date of the deposit

Next, I moved onto the withdrawal function,

• decreasing the balance by a given amount
• not allowing withdrawal of money not in the account
• storing the amount decreased by
• storing the balance after withdrawal
• storing the date of the withdrawal

Lastly, I ensured the format of the statement was correct per the given spec.
