Student-Database

Overview

This project is a Student-Database implemented in C using Linked Lists. The program allows users to perform various operations such as adding, deleting, modifying, sorting, and displaying student records.

Features

• Add a new student record
• Delete a specific student record by roll number or name
• Modify an existing student record
• Sort student records by roll number
• Reverse the linked list of student records
• Show all student records
• Delete all student records
• Save student records to a file for persistence
• Exit the program with or without saving

Compilation & Execution

Compile:

gcc student_record.c -o student_record

Run:

./student_record

Menu Options

Once executed, the program provides the following menu options:

-----------------------------
****STUDENT RECORD MENU**** |
-----------------------------
| a/A : Add new record      |
| d/D : Delete a record     |
| s/S : Show the list       |

File Storage

The records are stored in a file named databaseRecord.txt when saved. The format used is:

<Roll Number> <Name> <Marks>

Example:

1 John 85.50
2 Alice 92.75

Functions

The following functions are implemented:

• add_end(ST **ptr): Adds a student record at the end
• delete(ST **ptr): Deletes a student record by roll number or name
• modify(ST **ptr): Modifies an existing student record
• sort(ST *ptr): Sorts the records by roll number
• show(ST *ptr, ST **p): Displays all student records
• rev_link(ST **ptr): Reverses the linked list
• deleteall(ST **ptr): Deletes all student records
• save(ST *ptr): Saves student records to a file

Future Improvements

• Implement a graphical user interface (GUI)
• Add search functionality
• Implement database integration instead of file storage
