Executive Summary
Banking System Simulation is a C++ console application that models bank accounts, transactions, and account-type behavior using object-oriented programming.
Problem Statement
A banking workflow provides a practical way to model inheritance, polymorphism, encapsulation, and user interaction in C++.

Screenshots & Visuals
Real project screenshots and outputs appear first. Where a project has no existing screenshots, the visuals are grounded diagrams or output previews based on the actual project structure.
OOP Class Diagram
Grounded class diagram showing the Bank, BankAccount, CheckingAccount, and SavingsAccount relationship used in the C++ project.
Transaction Console Flow
Grounded console output preview based on the account creation, deposit, withdrawal, and balance update workflow.
Transaction Preview
create CheckingAccount #1024
deposit 250.00
withdraw 40.00
balance -> 210.00Challenges & Solutions
Challenge
Early software projects can become procedural without clear domain modeling.
Solution
Modeled banking behavior with dedicated classes and account-type inheritance.
Challenge
Account workflows need user-friendly state changes.
Solution
Built console interactions for account creation, transactions, and updated balances.
Results / Impact
Demonstrates practical software engineering through modular structure, readable workflows, and clear technical documentation.
Shows ability to convert course and research concepts into working systems with real implementation constraints.
