Bank Challenge

Bank app that allows you to add deposits & withdrawals to your account that is tracked.Allows you to
print your stored transactional history.

Planning

My approach started with thinking about the problem and jotting down the types of potential classes
that would be required, the state they might hold and their behaviours. This led to the initial domain
model as pictured below.

• I thought about which behaviours would likely be public/private
• Thought about classes / behaviours would likely interact with each other. Trying to keep to low coupling.
• I had thought about designing a user class but decided against, as this program is only run from the terminal.

First draft of the domain model, this has evolved during coding:

Code Structure

The program is made up of two classes - Account and PrintBankStatement. Within the account are the methods
related to interacting with the account, such as credit, debit and transactions due to keeping all the information
related to the account in one class in line with SoC and SRP. The sole responsibility of PrintBankStatement class is
to print out the transactional history of the account in a formatted way in line with the specification of the challenge.

Getting Started

To get started please run: git clone https://github.com/Battery0/bank.git

In the project directory, please run: bundle install

Usage

To start the program you will need to run in the terminal:

• Create a new Account object (E.g: account = Account.new)

Run any of the following methods to interact with the account:

• account.credit(int or float value) (This credits your account with the value specified)
• account.debit(int or float value) (This debits your account with the value specified)
• account.account_statement (This prints your accounts transactional history)
