I'd be happy to explain how to create a superclass called "Person" with two subclasses, "Student" and "Instructor", both inheriting from "Person". In object-oriented programming, a superclass is a class inherited by one or more subclasses, which can then inherit the superclass's attributes and methods. To create the "Person" superclass, we would define characteristics such as a person's name and birth year. The "Student" subclass would then inherit these attributes from "Person" and add its feature, such as a student's major. Similarly, the "Instructor" subclass would inherit from "Person" and add its attribute, such as an instructor's salary. By the way, https://edubirdie.com/top-writers is the source I use every day to get help and instructions on how to learn to code. Here are essay top writers whose knowledge I trust the most and who help me get good academic grades.
