c#
Write compile and test a program named DemoJobs. The program will instantiate three Job objects and demonstrate their methods as described below.
1. The Job class contains four private data fields: description, time, hourly rate, and total fee.
2. The description, time, and hourly rate fields will have public get and set properties. The total fee field will be read-only and have only a get property. The value of the total fee field will be calculated each time either the time or hourly rate is set.
3. The + operator will be overloaded so that two jobs can be added. The sum of two jobs is a new job containing:
a. The descriptions of both jobs joined by “and”.
b. The sum of the two times.
c. The hourly rate will be a weighted average of the two hourly rates. Be sure to use variables of the appropriate types, and to use meaningful names for all variables and methods
Explanation / Answer
using System;
public class AddJobs
{
private double totalFee;
public AddJobs(double TotalFee)
{
totalFee = TotalFee;
}
public static void Main()
{
Job job1 = new Job("washing windows", 5.00, 25.00);
Job job2 = new Job("walking a dog", 3.00, 11.00);
Job job3;
job3 = job1 + job2;
Console.WriteLine("The first job's description: {0} Total time needed to complete the job: {1} hours Hourly fee: {2} per hour", job1.Description, job1.Time, job1.Rate.ToString("C"));
TotalPay(job1);
Console.WriteLine("The second job's description: {0} Total time needed to complete the job: {1} hours Hourly fee: {2} per hour", job2.Description, job2.Time, job2.Rate.ToString("C"));
TotalPay(job2);
Console.WriteLine("The third job's description: {0} Total time needed to complete the job: {1} hours Hourly fee: {2} per hour", job3.Description, job3.Time, job3.Rate.ToString("C"));
TotalPay(job3);
}
public static void TotalPay(Job method)
{
double totalFee = method.Rate * method.Time;
Console.WriteLine("The total fee is: {0}", totalFee.ToString("C"));
}
}
class Job
{
public Job(string description, double time, double rate)
{
Description = description;
Time = time;
Rate = rate;
}
public static Job operator +(Job first, Job second)
{
string newDescription = first.Description + " and " + second.Description;
double newTime = first.Time + second.Time;
double newRate = (first.Rate + second.Rate) / 2;
double newTotalFee = newRate * newTime;
return (new Job(newDescription, newTime, newRate));
}
public string Description { get; set; }
public double Time { get; set; }
public double Rate { get; set; }
}
