Departmental Store Management Using C Language

Introduction

This application has been modified to include functionality such as calculating, adding, examining commodities, and more. The admin or user is kept up to date on the records with less effort, and it is highly liked by those in the business world. Because we are aware of businesspeople's busy and stressful schedules, this Departmental Store management system proves to be a fantastic relief for them because it is simple to use. This application has a lot of potential for reducing billing mistakes and shortening the time it takes to distribute invoices to clients. We don't have to worry about data loss with this system, and we don't have to worry about it being damaged.
