🎓 Student Management System (C)

A menu-driven Student Management System developed in C language using structures and binary file handling.

This project simulates a basic database system where student records can be stored, retrieved, modified, and deleted permanently using file operations.

⚙️ Compilation & Execution

Compile

gcc main.c -o student

Run (Linux / Mac)

./student

Run (Windows)

student.exe

---

🖥️ Program Menu

1. Add New Student
2. Search Student
3. Display All Students
4. Update Student
5. Delete Student
6. Exit

---

💾 Data Storage

All student records are saved inside:

data/student.dat

Binary storage provides:

• Fast read/write operations
• Direct structure storage
• Persistent data after program exit

---

📊 Student Structure

struct student {
    int roll_no;
    char name[25];
    char fname[25];
    int age;
    float marks;
};
