Create an application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains a model and a value for miles per gallon. Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload a ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation.

a. Modify the FitnessTracker class that includes data fields for a fitness activity, the number of minutes spent participating, and the date. The class includes methods to get each field. In addition, create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Create an application that demonstrates each method works correctly.
b. Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately.

- Question Create a class called Quadratic for performing arithmetic on and solving quadratic equations. A quadratic equation is an equation of the form ax2 + bx + c = 0 Where a !=0. Use double variables to represent the values of a, b, and c and provide a constructor that enables objects of this class to be initialized when they are created. Give default values of a = 1, b = 0, and c = 0. Create a char variable called variable to represent the variable used in the equation and give it a default value of x. The constructor should not allow the value of a to be 0. If 0 is given, assign 1 to a). Provide public member functions that perform the following tasks. add—adds two Quadratic equations by adding the corresponding values of a, b, and c. The function takes another object of type Quadratic as its parameter and adds it to the calling object. subtract—subtracts two Quadratic equations by subtracting corresponding values of a, b, and…arrow_forwardWrite a program named DemoJobs for Harolds 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 Harolds 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.arrow_forwardCreate an application named SalesTransactionDemo that declares several SalesTransaction objects and displays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and commission and a readonly field that stores the commission rate. Include three constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all the other fields to 0. An overloaded + operator adds the sales values for two SalesTransaction objects.arrow_forward

The class should have the appropriate methods to “set” and “get” the values of all fields. The class should also have a method to calculate the average of the three tests. To test the class, you should create a class demo that instantiates one object of the Grades class and asks the user enter the student name and the grades for the three tests.
