First OOP$-$Financials Ltd $($A Banking System for OOP Students$)$

Goal:

The goal of this assignment is to give an opportunity to practice core OOP concepts and put the concepts

of Abstraction, Encapsulation, Composition, Aggregation, Inheritance and Polymorphism, etc. to use.

You have to implement a console$-$based Banking system in this assignment. For this assignment, the

task is to develop a Banking System focusing on serving the financial needs of OOP students. The Bank

provides a number of services to its clients $($who are restricted to OOP students only$)$ more on this in

the following paragraphs.

Features of the system

$1.$ Account Management:

The bank allows the customers to open new accounts. Individuals can open multiple accounts $($up to $3$

accounts per person are allowed$).$ The bank supports opening and closing of accounts. Any time an

account goes into negative, as a result of some transaction, the account becomes dormant. Dormant

accounts need to be re$-$activated by depositing enough funds that bank balance becomes positive $(+100$

is the minimum allowed balance, below which account becomes dormant$).$

$2.$ User Management:

Modifications to information of each account holder. For each account holder, their university ID

number, and Address is recorded by the bank. Bank customers may ask for this information to be

updated.

$3.$ Transactions:

Bank supports usual transactions of withdraw and deposit. Additionally, bank keeps track of each

transaction that takes place. This can be using a "Transaction Ledger" class $($implemented by you of

course$).$ The ledger should support the functionality of locating transactions based on Account ID$,$ or

Account ID and Date. Each transaction object should also record the Date and time of transaction.

$4.$ Statement:

Bank Customers may ask the bank for Statement of their account. Statement contains all the

transactions, that have taken placed during a specific time period. $($You should implement. toString$()$

method for each transaction object to assist in getting nicely formatted Statement$).$

$5.$ Account Types:

Bank support Saving and Current Accounts. Current accounts can also be owned jointly. That is$,$ more

than one person may be owner of an account. Also, there is a small penalty of $0\mathrm{.}01\%$ of withdraw

amount when taking funds from a Saving Account.

Tasks:

$1.$ Identify classes, their data members and member functions required to build the system.

$2.$ Model the above system with the help of a UML class diagram.

$3.$ Develop a solution using C$++$ code to develop the above system. Also, provide a main function

that tests the functionalities of the system.
