In this c projects source code series we are going to create a c project about Departmental storage system. This Departmental storage system project is built using c language, a console-based application without using graphics. It has features where you can goods, edit goods, search, delete and display the data regarding goods.
The details regarding the goods like rate, product name, and the price are stored in a specific file using the method of file handling. You can display the data stored in the file whenever required.
The function void gotoxy(int x, int y) is used in this project which helps the user to print text in any place on the screen.
Let's get started
Create Simple C Console project in CodeBlocks IDE
This Departmental Management sytem consist of below modules
