209: Create a function that takes 2 point objects and computes distance between them

 

// Create a function that takes 2 point objects and computes distance between them

    Point p1(3, 4), p2(2, 2);
    cout << "Distance between p1 and p2 is: " << distance(p1, p2) << endl;

    return 0;

float distance(Point a, Point b)
{
    return sqrt(pow((b.x_coord - a.x_coord), 2) + pow((b.y_coord - a.y_coord), 2));

221: // In Task 2, we discussed multilevel inheritance with parameterized constructors for Student, UndergraduateStudent, and GraduateStudent classes in a university management system. Can you explain the advantages of using multilevel inheritance with specific details about the functions and data members in these classes? How were the parameterized constructors (e.g., setting student name, age, and ID) used to ensure that each class in the hierarchy correctly initializes its properties, such as creating an UndergraduateStudent named "John," aged 20, with a student ID of 12345
