Chapter 9, Problem 10E
- Write a
program named DemoJobs for Harold’s Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, "wash windows"), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. - Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following:
• His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000.
• His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10.
• If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605.
Devise an improved, weighted method for calculating Harold’s fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.

The application should be able to do the following :• Create a class called Person which contains 4 private fields : Name(string), Surname (string),Course(string), CRNumber(int).• The class must contain 4 public properties which will be used to get and set the values of the private fields.• The class must contain a default constructer. The class must also contain an overloaded constructer which should be able to set the values of each of the private fields.• The class must contain a static ViewInfo method which will be used to display information of a queue of person objects back to the user neatly grouped underneath each other as displayed above.• Once a user clicks on the “Add Person” button then the information in the respective textboxes should be used to create a Person object (using the properties or the overloaded constructor) and add it to a queue which is of type Person.
