Use an array of 20 components of type studentType. You will read in the names, id, and email from classroster.txt. The first line of the file will tell you how many students are in the class. To get the the GPA and program for each student you will need to read from studentlist.txt. The second file will have the id, program, and GPA for all of the students in the department. That means that not every student from studentlist.txt will be in classroster.txt. You will…

Pet Class Write a class named Pet, which should have the following data attributes: • _ _name (for the name of a pet) • _ _animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’) • _ _age (for the pet’s age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: • set_name This method assigns a value to the _ _name field. • set_animal_type This method assigns a value to the _ _animal_type field. • set_age This method assigns a value to the _ _age field. • get_name This method returns the value of the _ _ name field. • get_animal_type This method returns the value of the _ _animal_type field. • get_age This method returns the value of the _ _age field. Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet.
