Student Marksheet Management System - Programming Assignment

Objective

Design a comprehensive Student Marksheet Management System in C that demonstrates proficiency in data structures, file handling, and complex program design.

Requirements

Basic Functionality (25 points)

1. Create a struct to represent a student with the following attributes:

   • Roll Number (unique identifier)
   • Student Name
   • Marks for multiple subjects (maximum 10 subjects)
   • Total Marks
   • Percentage
   • Grade

2. Implement functions to:

   • Add new student records
   • Input marks for students
   • Calculate percentage and grade automatically
   • Display individual student marksheets

Intermediate Features (25 points)

3. Implement advanced record management:
   • Search student by roll number
   • Modify existing student records
   • Delete student records
   • Sort students based on:
     • Total marks
     • Percentage
     • Alphabetical order of names

Advanced Features (25 points)

4. File Handling Requirements:
   • Save student records to a binary file
   • Load student records from a binary file
   • Implement error handling for file operations
   • Provide options to:
     • Export marksheet to a text file
     • Import student data from a CSV file

Error Handling and Validation (15 points)

5. Implement robust input validation:
   • Prevent duplicate roll numbers
   • Validate mark inputs (0-100 range)
   • Handle maximum student limit (100 students)
   • Implement proper error messages for invalid inputs

Bonus Challenge (10 points)

6. Implement additional advanced features:
   • Generate performance reports
   • Create a simple statistical analysis of class performance
   • Implement a basic password protection system for the application

Grading Criteria

• Correctness of implementation
• Code readability and organization
• Efficient memory management
• Comprehensive error handling
• Creativity in solving complex problems

Submission Guidelines

• Submit complete source code
• Include a README file explaining your implementation
• Provide clear comments in the code
• Demonstrate understanding of C programming concepts

Recommended Approach

1. Break down the problem into smaller functions
2. Use modular programming techniques
3. Implement one feature at a time
4. Test thoroughly after each implementation
5. Use dynamic memory allocation where appropriate

Hints

• Use struct and arrays effectively
• Implement careful input validation
• Consider using function pointers for sorting
• Utilize file handling functions like fopen(), fwrite(), fread()
• Handle memory allocation carefully

Optional Extensions

• Implement a graphical user interface (GUI)
• Add encryption for student records
• Create a web-based version of the marksheet system
