Student Record System

What it does

This is a command-line program I built in C that acts like a persistent digital notebook for student data. It lets you input a student's roll number, name, and marks, and automatically writes that data into a local text file called student.txt.

Because it saves everything to an actual file on your hard drive, your records don't vanish when you close the terminal or turn off your computer.

Why I built this

I wanted to build a project that moved out of the temporary RAM space and into actual file storage. Working on this project helped me figure out:

1. Persistent Storage: How to use basic file handling operations to read and write data permanently.
2. Data Organization: Using struct to group a string (name), an alphanumeric string (roll number), and a floating-point number (marks) under a single student profile.
3. Handling Menu Loops: Keeping a terminal application running smoothly in a continuous loop until the user explicitly decides to quit.

How it works (In Simple Terms)

• The Interactive Menu: Gives you a simple 1, 2, 3 choice workflow directly in the terminal to add new data, view existing records, or exit the program cleanly.
• Structures (Struct): Bundles different variables together under one student profile layout so the data doesn't get mismatched.
• File Handling: Opens a local text file using C's FILE pointer to append records to the end of the file or parse them sequentially to read them back onto the screen.

How to run it

1. Open your terminal or command prompt inside this project folder.

2. Compile the source file using a standard C compiler: gcc records.c -o records

3. Run the compiled executable: ./records

Tech Used

• Language: C
• Compiler: GCC
• Core Concepts: File I/O (fopen, fprintf, fscanf), Custom Structures, and Control Flow
