Department Store Management System project Using C languages

Overview of the Department Store project

This Department Store Management System Project is a simple application made in a console without graphics. In this project, you can manage a typical “fashion clothing” department store. You can add assets, edit assets, search, delete and display assets.

File management has been used to record the information (rate, quantity, name and code) of the goods added. You can search for merchandise by rate, code or quantity. And the same goes for exhibitions; You can view items by quantity, rate or code.

The source code of this project is complete and error-free. It is compiled into Code::Blocks with the GCC compiler. Unlike other C program source codes, I have not shown the source code for this C Department Store Management System project here because it is too long: more than 800 lines. You can directly download the source code and application file from the link given below. Customer Billing System Project Using C language Similar project.

Department Store Management System in C project can be useful for students or professionals who want to learn C programming language. This project can also be modified to suit your individual needs. I hope this Department store project will help you to improve your skills.

Functions Used in Department Store Management System:

Basically, I have divided the functions I use in this project into four main functions. And those individual functions are described in short comments within the source code.

  1. Performance Functions:
  2. Main Menu Functions:
  3. Show Submenu Function:
  4. Check the works:

void c_code(char[]);
control int (char []);
void getoxy(int x, int y) – I am describing this function in every C project posted on this site. You need to understand this feature as it is one of the most important features used in this department store management project.
