Question

Complete the code in C#. Part 1 is one program. Part 2 is another program. They're seperate programs, but use part 1 to figure out part 2.

Part! Create a new console application named Demojobs. Write a program for Harold's Home Services. The program should instantiate an array of 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), and sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Part 11 Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: a. His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. b. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. c. 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+0 method. Write a program named Demojobs2 that demonstrates all the methods in the class work correctly. Sushmith

Answer 1

Here a new Console Application in C# is created using Visual Studio 2017 with name "DemoJobs".This application contains a class with name "Program.cs".Below are the details of this class.

Program.cs :

//namespace
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//application namespace
namespace DemoJobs
{
class Program //C# class
{
//entry point , Main() method
static void Main(string[] args)
{
//creating object of Job class
Job job1 = new Job();
job1.Description = "wash windows";//set description
job1.PerHourRate = 25.00;//set per hour rate
job1.TimeInHours = 3.5;//set time in hours
//display job1 details
Console.WriteLine("----------Job1 details-----------");
Console.WriteLine("Description: "+job1.Description+",Per Hours Rate: "+job1.PerHourRate+", Time in Hours:"+job1.TimeInHours);
Console.WriteLine("Total Fee : "+job1.totalFee);
//creating object of Job class
Job job2 = new Job();
job2.Description = "wash cloths";//set description
job2.PerHourRate = 30.00;//set per hour rate
job2.TimeInHours = 1.5;//set time in hours
//display job2 details
Console.WriteLine("----------Job2 details-----------");
Console.WriteLine("Description: " + job2.Description + ",Per Hours Rate: " + job2.PerHourRate + ", Time in Hours:" + job2.TimeInHours);
Console.WriteLine("Total Fee : " + job2.totalFee);
//creating another object of job class
Job job3 = new Job();
job3 = job1 + job2;//add two objects
//display job3 details
Console.WriteLine("----------Job3 details-----------");
Console.WriteLine("Description: " + job3.Description + ",Per Hours Rate: " + job3.PerHourRate + ", Time in Hours:" + job3.TimeInHours);
Console.WriteLine("Total Fee : " + (job1.totalFee+job2.totalFee));
Console.ReadKey();//to hold the screen

}
}
//C# class
class Job
{
//data fields
private string description;
private double timeInHours;
private double perHourRate;
public double totalFee;
//getter and setter methods
public string Description
{
get { return this.description; }
set { this.description = value; }
}
public double PerHourRate
{
get { return this.perHourRate; }
set { this.perHourRate = value;
this.totalFee = this.perHourRate * timeInHours;
}
}
public double TimeInHours
{
get { return this.timeInHours; }
set {
this.timeInHours = value;
this.totalFee = this.perHourRate * timeInHours;
}
}
//overloaded + operator
public static Job operator +(Job j1,Job j2)
{
Job j3 = new Job();//creating Job class object
//description of two jobs
j3.description = j1.description + " and " + j2.description;
//sum of time in hours
j3.timeInHours = j1.timeInHours + j2.timeInHours;
//average of per hour rate
j3.perHourRate = (j1.perHourRate + j2.perHourRate) / 2;
return j3;//return j3
}

}
}

Output : Run application using F5 and will get the screen as shown below
