In this c projects source code series we are creating a console application of Student Management System. The Student Record system is one of the best projects you can design using C programming. The data stored in a particular file in this project is by using the data handling method.
The operations like inserting, modifying, searching, and deleting the record are done in this project. You can also generate the mark sheet of the students in this application.
There are two parts in the console window- one for the static that doesn't change and the other for dynamic which changes with time. Different colors are used in the code to make them attractive. It is designed using Code:: Blocks with GCC compiler. Some changes should be made in the code, so it is incomplete
