Inheritance

This repository contains a C++ program demonstrating student records management, focusing on course registration, grade handling, and OOP concepts such as inheritance, class relationships, and operator overloading.

1. Project Overview

The program demonstrates:

• Creation and management of Student and Course objects
• Class aggregation and relationships
• Operator overloading for course addition, assignment, comparison, and output
• Dynamic memory management with exception handling
• Stream manipulation for outputting student data

---

2. Key Concepts

2.1 Class Relationships

• Course Class Attributes:
  • Course Code, Course Name, Course Semester
• Student Class Attributes:
  • Declared Courses (currently enrolled)
  • Passed Courses (completed with grade)

2.2 Operator Overloading

• += Operator: Adds a course to a student’s declared courses
• Assignment Operator (=): Copies student attributes
• Comparison Operators (==, !=, <, <=, >, >=): Compares students by semester
• Stream Insertion Operator (<<): Outputs detailed transcript and average GPA

2.3 Exception Handling

• Handles errors during dynamic memory allocation and file operations
• Provides meaningful error messages for memory or file access failures

---

3. Functionality

Key functions include:

• Adding courses to a student’s record (+=)
• Copying student attributes (assignment operator)
• Comparing students by semester
• Outputting student transcripts using stream insertion

---

4. Conclusion

This project illustrates OOP inheritance and class relationships in C++, combining dynamic memory management, operator overloading, and exception handling to implement a functional student-course management system.
