- (Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.1- Create a class Rational for performing arithmetic with fractions.Write a driver program to test the class. Provide a constructor thatenables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in caseno initializes are provided and should store the fraction in reducedform. Provide a private function to reduce numbers.Provide Public member functions for each of the followingarithmatic’s functions (addition – subtraction – multiplication –division), printing in the form a/b, printing in floating point formatand final overload the == and != operators to allow comparisons oftwo fraction numbers.Include any additional operations that you think would be useful fora rational number class.Design, implement, and test your class.Create a class called Date that includes three pieces of information as data members—a month (type int ), a day (type int ) and a year (type int ).

- Write a class named Car with member variables: yearModel, Make, Speed as private.Use a Constructor that accepts year model and make as arguments. It should also assign 0 to thespeed use accelerate and brake functions that add and subtract 5 from speed each time it is called.Demonstrate the class in a program that creates a Car object, and then calls the accelerate function5 times. After each call to the accelerate function, get the current speed of the car and display it.Then, call the brake function five times. After each call to the brake function, get the current speedof the car and display it.Martin your friend has declared a class called Employee with the following members; EmployeeID, Employee Name, Basic Salary, Allowance, and Net Salary.a) Write a code for a member function called get_input that will be used for data input.b) Write a code for a member function called Calculate that will be used to calculate netsalary as the sum of basic salary and allowances. c) Write a code for the default constructor that will assign values to the variables in theEmployee class. d) Write a code for the default constructor. e) Write a complete program that captures and includes all the details in (a-d) above.Run the code and show your output.(Rational Class) Create a class called Rational for performing arithmetic with fractions.Write a program to test your class. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to beinitialized when it’s declared. The constructor should contain default values in case no initializersare provided and should store the fraction in reduced form. For example, the fractionwould be stored in the object as 1 in the numerator and 2 in the denominator. Provide publicmember functions that perform each of the following tasks:a) Adding two Rational numbers. The result should be stored in reduced form.b) Subtracting two Rational numbers. The result should be stored in reduced form.c) Multiplying two Rational numbers. The result should be stored in reduced form.d) Dividing two Rational numbers. The result should be stored in reduced form.e) Printing Rational numbers in the form a/b, where a is…
- Create a base class called Insect. All insects belong to an Order [i.e. “Hemiptera” (ants), “Siphonaptera” (fleas), “Termitoidae” (termites), “Gryllidae” (crickets), etc.] and have a size that is measured in millimeters (use a double data type). Provide a default constructor that initializes the size to zero and outputs the message “Invoking the default Insect constructor” and another constructor that allows the Order and size to be set by the client. This other constructor should also output the message “Invoking the 2-argument Insect constructor.” Also create a destructor for this class that outputs the message “Invoking the default Insect destructor.” Your Insect class should have a function called Eat that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the order and size to be accessed.CPP OOP - Create two classes named Mammals and MarineAnimals. Create another class named BlueWhalewhich inherits both the above classes. Now, create a function in each of these classes which prints"I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well asMarine Animals" respectively. Now, create an object for each of the above class and try callingfunction of Mammals by the object of Mammalfunction of BlueWhale by the object of BlueWhalefunction of each of its parent by the object of BlueWhalefunction of MarineAnimal by the object of MarineAnimalC++ Write a class named Car with member variables: yearModel, Make, Speed as private.Use a Constructor that accepts year model and make as arguments.

- IN JAV1. Declare a class called country that contains a function called language that prints "English" Define 3 classes and they all inherit from country A brand named Australia A class named Saudi Rewrite the language function and change the implementation of the function so that it prints "Arabic" A class called Spain Rewrite the language function and change the implementation of the function so that it prints "Spanish" Build a Test class to test the code with the Main function and then create objects of the three classes that Workshop of the father's class Then call the language function The result should be as in the picture English Arabic SpanishCreate two classes named Mammals and MarineAnimals. Create another class named BlueWhale which inherits both the above classes. Now, create a function in each of these classes which prints "I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well as Marine Animals" respectively. Now, create an object for each of the above class and try calling:1 - function of Mammals by the object of Mammal2 - function of MarineAnimal by the object of MarineAnimal3 - function of BlueWhale by the object of BlueWhale4 - function of each of its parent by the object of BlueWhale Note: use OOP concepts and use C++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…
