🎓College Internal Marks Management System (C)

🧾Description

This project implements a simple college internal marks management system using the C programming language.
It demonstrates how pointers are used with 1-D and 2-D arrays to store, access, and process student marks.

The program calculates average marks for a subject, total marks for each student, and identifies the class topper using pointer arithmetic and pointer expressions.

✨Features

• Stores marks for one subject using a 1-D array
• Stores marks for multiple subjects using a 2-D array
• Uses pointers to access array elements
• Demonstrates pointer arithmetic and pointer expressions
• Calculates average marks
• Calculates total marks per student
• Identifies the topper

---

🧩Concepts Used

• C Arrays (1-D and 2-D)
• Pointers
• Pointer arithmetic
• Pointer expressions
• Loops and nested loops
• User input using scanf

---

🔁Program Flow

1. User enters the number of students and subjects
2. Marks for one subject are stored using a pointer
3. Average marks are calculated
4. Marks for multiple subjects are stored using a pointer to a 2-D array
5. Total marks for each student are calculated
6. Topper is identified based on total marks

📸Output Screenshot

Below is a screenshot showing the execution and output of the program.

▶️How to Compile and Run

1️⃣Write code
→ Pointers.c
2️⃣ Compile it
→ gcc Pointers.c -o Pointers
3️⃣ Run it
→ ./Pointers

📂File Structure

Pointers.c // Main C source file
README.md // Project documentation

---

⚠️Limitations

• Assumes valid integer input
• No data persistence (data is lost after program ends)
• Does not include grade calculation

---

🚀Future Improvements

• Use dynamic memory allocation (malloc)
• Add grade calculation
• Store marks in files
• Convert into a menu-driven program
