Look at the following description of a problem domain:
A doctor sees patients in her practice. When a patient comes to the practice, the doctor performs one or more procedures on the patient. Each procedure performed has a description and a standard fee. As patients leave, they receive a statement that shows their name and address, as well as the procedures that were performed and the total charge for the procedures.
Assume that you are creating an application to generate a statement that can be printed and given to the patient.
A.) Identify all of the potential classes in this problem domain.
B) Refine the list to include only the necessary class or classes for this problem.
C) Identify the responsibilities of the class or classes that you identified in step B.

Create the following classes with the attributes as specified: ----------------------------- Class Club Holds the following information: club number – club’s registration number name –the name of the club address – address of the club telephone number – 10-digit phone number ---------------------------------- Class Registrant Holds the following information: registration number – identification number for a registrant name – a registrant’s name date of birth address – address of the registrant telephone number – 10-digit phone number ---------------------------------------- Class Swim meet Holds the following information: Start date – start date of the…arrow_forwardWhat does the total mean in the assignment: Specifications: Lions, Tigers and Bears Pet Clinic needs an application that displays basic services. The application should be designed with check boxes to select the various services (such as office call, vaccination, grooming, etc). As each service is selected, the charge for the service should display in an associated label. (When the check mark is removed, the amount should be removed). As each selection is made, the charges should be added into the total (a variable… consider scope), and displayed in a Total Due area on the application (currency format). Align all numeric data appropriately. Consider what should happen when the check mark is removed. Include at least 8 services that your pet clinic performs. Include a Clear and Exit button. The clear should clear all check boxes, appropriate labels, and the total variable. Use the standard Microsoft naming conventions for all controls. Include appropriate comments in your code.arrow_forward
- Assignment #2 Design an application to search in a database table of employee records. Each employee record consists of an ID, first name, last name, job title. The user interface should look similar to the sketch shown below. A text field is used to input the search query. A combo box is used to choose the search criteria (e.g. search by ID, search by first name, search by last name). By choosing any criteria and clicking on the "search" button, the correct results should be shown on the "results" pane.

For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work.
