14,016 Pointsorder of classes
im pretty confused. how come the Student class cannot be declared before the person class? Maybe there is something i didn't understand. I thought I understood hoisting. it was basically to define the class before calling the class. I don't see how a different order of classes affect anything as long as you call them after they are both defined. Please and Thank you for the help.

The issue here is "dependency", which means that you should always define a class before any others that reference it. Since a Student
is a special kind of Person
then Person
needs to be defined first.
