- Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.An organization has two types of employees: regular and adhoc. Regular employees get a salary which is basic + DA + HRA where DA is 10% of basic and HRA is 30% of basic. Adhoc employees are daily wagers who get a salary which is equal to Number * Wage (i) Define the classes shown in the following class hierarchy diagram: Employee name eno salary () Regular Adhoc wage пnber days (int n) salary O Basic salary (). Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Write a member function called getcrow(). This function should return the value of the crowbar data. Assume the function is defined within the class definition. Opp Java
- Q2: Write a program that has an abstract base class. This class should have four member data variables and a pure virtual function. It should also have a method for setting the data variables. Derive a class from Base class and override a method in the base class. Write a main function that creates an object of derived class and sets the variables. Also write a top-level function that will take a parameter of type base class and return the value of the appropriate (override) function. LANGUAGE: C++1. Which is used to create an abstract class? A. Creating at least one member function as a pure virtual function B. Creating at least one member function as a virtual function C. Declaring as Abstract class using virtual keyword D. Declaring as Abstract class using static keyword E. None of the above. Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Write a member function called getcrow(). This function should return the value of the crowbar data. Assume the function is defined within the class definition.
- Define a class Book in C++, which has the following private data members:a) BookNameb) BookAuthorc) BookIDClass Book has a constructor, a destructor and a member function to display state of the object. All member functions are defined outside the class.Create an object MyBook from class Book in main( ) function by passing book name, author name and book ID at the time of object instantiation. In main() function, display the state of the created object MyBook by calling member function.Part I: Class Creation Create a composition between the classes Job and Salary. Class Salary a. data member: 1. money b. constructors: 1. default constructor 2. user defined constructor with a parameter to set money c. standard accessor and mutator functions Class Job a. data members: title (name of the job) salary (object of type Salary) b. constructors: 1. default constructor 2. user defined constructor to set title and salary 3. implement constructor delegation c. standard accessor and mutator function for titleDesign a class bookType that defines a book as a class. a. Each object of the class bookType will hold the following information about a book: title number of authors up to four authors publisher year published ISBN 13 (with dashes) price number of copies in stock (may be 0) b. Include the member functions to perform the various operations on objects of type bookType: Include individual get and set functions for all member variables. c. Add a member function to update the number of copies in stock. d. Add the appropriate constructors and a destructor (if one is needed). Ensure a default constructor is coded and the constructor initializes all data members. Remember, an array of classes uses a default constructor only. e. ALL member variables must be private and accessed through member functions. The main client program CANNOT access the variables directly. f. Ensure the class declaration and class implementation files are in separate header and code (.cpp) files. This assignment will…
- If a base class declares a pure virtual function, a derived class must implement thatfunction to become a concrete class. T/FCan a parent class object access its child class member functions? If yes, how?Define the missing member function. Use "this" to distinguish the local member from the parameter name. #include <iostream>using namespace std; class CablePlan{ public: void SetNumDays(int numDays); int GetNumDays() const; private: int numDays;}; // FIXME: Define SetNumDays() member function, using "this" implicit parameter.void CablePlan::SetNumDays(int numDays) { /* Your solution goes here */ } int CablePlan::GetNumDays() const { return numDays;} int main() { CablePlan house1Plan; int userNum; cin >> userNum; house1Plan.SetNumDays(userNum); cout << house1Plan.GetNumDays() << endl; return 0;}
