A professional banking system application developed in C++, designed to manage banking operations and administrative access through a structured, multi-stage development approach.
Core Client Management
- 👥 Purpose: Establishing the base system using CRUD operations.
- 🛠️ Features: Creating, Reading, Updating, and Deleting client accounts efficiently.
- 💾 Technical: Data is handled through
Vectorsand stored permanently inClients.txt.
Banking Transactions & Logic
- 💳 Purpose: Transforming the system into a functional financial application.
- 🛠️ Features: Added a robust transactions system for deposits, withdrawals, and balance reports.
- 💾 Technical: Implemented strict validation checks to prevent negative balances and ensure data integrity.
Administrative Access & Permissions
- 🔑 Purpose: Implementing a professional-grade administrative system.
- 🛠️ Features: Added secure user login and a granular permission system for all system features.
- 💾 Technical: Utilized
Bitwise Operatorsfor efficient permission management and session tracking for theCurrentUser.
The entire project is currently built using Procedural Programming (Functional Programming), focusing on modular functions, structured data, and clean control flow. This approach was essential to master the logic and data flow of the banking system.
This project serves as a solid foundation for my upcoming development phase. I am planning to refactor the entire system into Object-Oriented Programming (OOP), utilizing Classes, Inheritance, and Polymorphism. This will significantly improve scalability, code reusability, and maintainability for future banking modules.
- ⚙️ Clean Architecture: Using
EnumsandSwitch-Casefor highly organized navigation. - 🛡️ Advanced Security: Dynamic input validation and access control to protect sensitive data.
- 🚀 Scalable Code: Designed with modularity in mind to allow for future extensions.
A practical project from the Programming Advices platform (Course 7). 👨🏻💻
