3. Person and Customer Classes The Person and Customer Classes Write a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.

Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than $150• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all…
Chapter 9 defined the struct studentType to implement the basic properties of a student. Define the class studentType with the same components as the struct studentType, and add member functions to manipulate the data members.

Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute.

1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…
