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.

For example if, the output should be in the following format (only two automobiles shown): Automobile 1 2017 honda Price is $30,000.00 Automobile 45 2016 Toyota Price is $20,000.00 Total for all Automobiles is $50,000.00arrow_forwarduse FractionDemo program as a Console Application that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set accessor for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced…arrow_forward
