- Create class Date.
- The class definition will contain prototypes for member function Date like setDate.
- The private integer members month, day and year.
- A member function nextDay is included to increment the day by one.

(Combining Class Time and Class Date) Combine the modified Time class of Exercise 17.7and the modified Date class of Exercise 17.8 into one class called DateAndTime. (In Chapter 19, we’lldiscuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printStandard and printUniversal to output the dateand time. Write a program to test the new class DateAndTime. Specifically, test incrementing thetime into the next day.
(Using a Class Without a using Directive) Explain how a program could use class stringwithout inserting a using directive.
(The Fan class) Design a class named Fan to represent a fan. The class contains:■ Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denotethe fan speed.■ A private int data field named speed that specifies the speed of the fan (the default isSLOW).■ A private boolean data field named on that specifies whether the fan is on (the default is false)
■ A private double data field named radius thatspecifiesthe radius of the fan (the default is5).■ A string data field named color thatspecifiesthe color of the fan (the default is blue).■ The accessor and mutator methodsfor all four data fields.■ A no-arg constructorthat creates a default fan.■ A method named toString() that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns the fan color and radius along with the string “fan is off” in onecombined string.Draw the UML diagram for the class and…

- (Using CPP) Create a class that imitates part of the functionality of the basic data type int. Call the class Int (note different capitalization). The only data in this class is an int variable. Include member function to initialize an Int to 0. Write proper getter & setter functions to initialize it to an int value and to return this when needed. Also write a function to display it (it looks just like an int) and to add two Int values. Write a main program that exercises this class by creating one uninitialized and two initialized Int values, adding the two initialized values and placing the response in the uninitialized value, and then displaying this result. Save the file as Int.cpp.arrow_forward(Querying an Array of Invoice Objects) Use the class Invoice provided in the lab assignment to create an array of Invoice objects.Class Invoice includes four properties—a PartNumber (type int), a PartDescription (type string), a Quantity of the item being purchased (type int) and a Price (type decimal).Write a console application that performs the following queries on the array of Invoice objects and displays the results:a) Use LINQ to sort the Invoice objects by PartDescription.b) Use LINQ to sort the Invoice objects by Price.c) Use LINQ to select the PartDescription and Quantity and sort the results by Quantity.d) Use LINQ to select from each Invoice the PartDescription and the value of the Invoice(i.e., Quantity * Price).

- (Enhancing Class Rectangle) Create a more sophisticated Rectangle class than the one youcreated in Exercise 17.11. This class stores only the Cartesian coordinates of the four corners of therectangle. The constructor calls a set function that accepts four sets of coordinates and verifies thateach of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set function also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member functions that calculate the length, width, perimeter and area. The length is the larger of the twodimensions. Include a predicate function square that determines whether the rectangle is a squarearrow_forward4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forwardEdit only the class definition. DO NOT CHANGE the code given under 'main' please. Steps: Additionally implement any Python Magic/Dunder methods such that instances of the class minimally:1.
