Chapter 6, Problem 7PP
Write a Temperature class that represents temperatures in degrees in both Celsius and Fahrenheit. Use a floating-point number for the temperature and a character for the scale: either ‘C’ for Celsius or ‘F’ for Fahrenheit. The class should have
- Four constructors one for the number of decrees, one for the scale, one for both the decrees and the scale, and a default constructor. For each of these constructors, assume zero degrees if no value is specified and Celsius if no scale is given.
- Two accessory methods one to return the temperature in degrees Celsius, the other to return it in degrees Fahrenheit. Use me formulas from Practice Program 5 of Chapter 3 and round to the nearest tenth of a degree.
- Three set methods: one to set the number of degrees, one to set the scale, and one to set both.
- Three comparison methods: one to test whether two temperatures are equal, one to test whether one temperature is greater than another, and one to test whether one temperature is a less man another.
Write a driver program that tests all the methods. Be sure to invoke each of the constructors, to include at least one true and one false case for each comparison method, and to test at least the following three temperature pairs for equality; 0.0 degrees C and 32.0 degrees F, –40.0 degrees C and –40.0 degrees F, and 100.0 degrees C and 212 0 degrees F.

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…

In Chapter 3, you created a Rental class for the company. The Rental class contains two public final static fields that hold the number of minutes in an hour and the hourly rental rate ($40), and four private fields that hold a contract number, number of hours for the rental, number of minutes over an hour, and the price. It also contains two public set methods and four public get methods. Now, modify the Rental class to contain two overloaded constructors. One constructor accepts a contract number and number of minutes as parameters. Pass these values to the setContractNumber() and setHoursAndMinutes() methods, respectively. The setHoursAndMinutes() method will automatically calculate the hours, extra minutes, and price. The other constructor is a default constructor that passes "A000" and 0 to the two-parameter constructor. Save the file as Rental.java. b. In Chapter…arrow_forward

- in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…arrow_forwardCreate an Investment class that contains fields to hold the initial value of an investment, the current value, the profit (calculated as the difference between current value and initial value), and the percent profit (the profit divided by the initial value). Include a constructor with two arguments: initial, and current values and then calculate profit, and percent profit, and a display function that displays all fields. Create a House class that includes fields for street address and square feet, a constructor that requires values for both fields, and a display function. Create a HouseThatIsAnInvestment class that inherits from Investment and House. It includes a constructor (in order to pass arguments to its parent constructors) and a display function that calls the display functions of the parents. Write a main() function that declares a HouseThatIsAnInvestment and displays its values.arrow_forwardPYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciatedarrow_forward
