- 6. Write a program to create a class Triangle with three member integer variables side1, side2, and side3. Write the parameterized constructor for the class and write a member function findArea that displays the area of the triangle in the output. In C++Q1: Create two classes named Mammals and SeaAnimal. Create another class named Whale whichinherits both the above classes. Now, create a function in each of these classes which prints "I ammammal" in class Mammals, "I am a marine animal” in class Marine and "I belong to both thecategories: Mammals as well as Marine Animals" in class Whale. Now, create an object for each of theabove class in main function and try calling.1 - function of Mammals by the object of Mammal2 - function of SeaAnimal by the object of SeaAnimal3 - function of Whale by the object of Whale4 - function of each of its parent by the object of Whale2.3. Third Exercise Create a Point class (or change the corrected version from Exercise 01) with two private properties representing x and y coordinates, each of which defaults to the constants originx and originY, which are both initialised to 0. Provide three overloaded constructors: the first one sets the coordinates to their default values; the second gets the coordinates x and y as parameters; and the third receives an object of type Point and transfers its coordinates to the current (this) Point object. Provide a function toString() { [native code] } function that returns a String containing the point coordinates; an example of the delivered result is as follows: (5.1.3, 2.3) Create a PointTest class to put the various constructors and function toString() { [native code] } function to the test.
- Create a class Person with data member Name, age, address and citizenship number. Write a constructor to initialize the value of a person. Assign citizenship number if the age of the person is greater than 16 otherwise assign value zero to citizenship number. Also create a function to display the values.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 MarineAnimal7.26 LAB: Nutritional information (classes/constructors) Given main(), complete the FoodItem class (in file FoodItem.java) with constructors to initialize each food item. The default constructor should initialize the name to "Water" and all other fields to 0.0. The second constructor should have four parameters (food name, grams of fat, grams of carbohydrates, and grams of protein) and should assign each private field with the appropriate parameter value. Ex: If the input is: Water the output is: Nutritional information per serving of Water: Fat: 0.00 g Carbohydrates: 0.00 g Protein: 0.00 g Number of calories for 1.00 serving(s): 0.00 Ex: If the input is: M&M's 10.0 34.0 2.0 3.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 3.0 is the number of servings, the output is: Nutritional information per serving of M&M's: Fat: 10.00 g Carbohydrates: 34.00 g Protein: 2.00 g Number of calories for 1.00…
- Assume that class B is derived publicly from class A. Class A has two functions, f1() and f2(). Function f2() is virtual. Assume the following statements statements:A* ptr=new B; ptr->f1(); ptr->f2(); Fill in the blank.The function f1() as defined in class ____ will be used. The function f2() as defined in class _____ will be used. In question 1, the call to ptr->f2() is an example of _______________________.(C++) 21. The preprocessor directive #ifndef can be used in a class header file to a) Prevent the class declaration from being included multiple times b) Declare a class namespace c) Implement the class member functions d) None of the above For questions 22 and 23, refer to the following code: class SwimmingPool{ private: int area; int gallons; public: SwimmingPool(); void setArea(int); void setGallons(int); int getGallons() const { return gallons; }}; 22. Which of the following lines of code would you have in an implementation of the setGallons function? a) SwimmingPool() b) void SwimmingPool::setGallons(int g) c) SwimmingPool::SwimmingPool() d) void SwimmingPool()::setGallons(int g) 23. True/False: function getGallons() is an inline member function 24. Design a class called Date. The class should store a date in three private integers: month, day, year. There should be a member function to print out the date in the month/day/year format, e.g.…Create a class called Distance containing two members feet and inches. This class represents distance measured in feet and inches. For this class, provide the following functions: a. A no-argument constructor that initializes the data members to some fixed values. b. A 2-argument constructor to initialize the values of feet and inches to the values sent from the calling function at the time of creation of an object of type Distance. c. Add distance function to add two distances: Feet and inches of both objects should add in their corresponding members 12 inches constitute one foot. Make sure that the result of addition doesn’t violate this rule. d. Is greater: should return a variable of type bool to indicate whether 1st distance is greater than 2nd or not. e. Is smaller: should return a variable of type bool to indicate whether 1st distance is smaller than 2nd or not. f. Is greater equal: should return a variable of type bool to indicate whether 1st distance is greater than or equal…

In question 14, the call to ptr->f2() is an example of _______________________.create two classes named mammals and marine animals. create another class named blue whale which inherits both the above classes.now, create a function in each of these classes which prints "I am mammal", "I am 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 function of a mammal by the object of mammal function of blue whale by the object of blue whale function of each of its parent by the object of blue whale function of marine animal by the object of marine animal(Program) a. Complete the following class by including functions corresponding to the two prototypes listed in the declaration section: classElevatorprivate:intelNum;//elevatornumberintcurrentFloor;//currentfloorinthighestFloor;//highestfloorpublic:Elevator( int=1,int=1,int=15);//constructorvoidrequest( int);; In this definition, the data member elNum is used to store the elevator’s number, the data member currentFloor is used to store the elevator’s current floor position, and the data member highestFloor is used to store the highest floor the elevator can reach.The constructor should allow initialization of an object’s three data members with the data passed to the constructor when an Elevator object is instantiated. The request function should code the following algorithm: If a request is made for a nonexistent floor, a floor higher than the topmost floor, or the current floor Do nothing ElseIf the request is for a floor above the current floor Display the current floor number While not at the designated floor Increment the floor number Display the new floor number EndWhile Display the ending floor number Else // the request must be for a floor below the current floor Display the current floor number While not at the designated floor Decrement the floor number Display the new floor number EndWhile Display the ending floor number EndIf b. Include the class written for Exercise 3a in a complete program, and verify that all member functions work correctly.
