OOP.Finalp4

** This project is built on 3 part previous from this final one. each part builds on the one previous of it. **

part 1 of this project (basic system design):

// adding using system as needed class Student { public string StudentId { get; set; } public string Name { get; set; } public int Age { get; set; } public List CoursesEnrolled { get; set; }

public Student(string studentId, string name, int age)

}

public void EnrollCourse(string course)
{
    CoursesEnrolled.Add(course);
}

public void DropCourse(string course)
{
    CoursesEnrolled.Remove(course);
}

public void DisplayInformation()
{
    Console.WriteLine("Student ID: " + StudentId);

part 2: // add using system as needed namespace OOP.FinalP2 { // Abstract class representing a person abstract class Person { public string Id { get; set; } public string Name { get; set; }

    // Abstract method to display information
    public abstract void DisplayInformation();

    }

    public void DropCourse(string course)

            Console.WriteLine();
        }

        Console.ReadLine();
    }
}

}

part 3 is the same as part 4 without the LINQ queiries and the 'search based on specific criteria' method
