Bank Management using C concepts

1st semester project

Overview

This console-based banking management project was developed for our first semester project to practically apply our understanding of the C/C++ programming languages. The system uses a file-based storage system to persist data across sessions.

We worked upon this project as a group where my work mainly involved implementing:

Account management, Transaction, Credit card information and navigating around the project.
