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.

C++ Shape is an abstract class with a pure virtual function: Area(). (2) Circle is inherited from Shape, with a data member Radius, and a member function Area() to get the area of a circle. (3) Triangle is inherited from Shape, with two data members Bottom-length and Height, and a member function Area() to get the area of a triangle. Please complete the definition of Shape, Circle and Triangle, and define other necessary functions, to let a user can use Shape, Circle and Triangle as follows: void main( ) { Shape* p = new Circle(2); cout << "The area of the circle is: " << PrintArea(*p) << endl; Triangle triangle (3,4); cout << "The area of the triangle is: " << PrintArea(triangle) << endl; delete p; } The outputs: The area of the circle is: 12.56 The area of the triangle is: 6 //Your codes with necessary explanations: My code:…
6. Write an abstract class “Student” that has the attribute “name”, “id”, “cgpa”, totalFees.“Student” class has an abstract function fees(totalFees), concrete function toString().The fees function varies student to student. If any student has CGPA more than 3.90then he/she study with full free. If any student has CGPA more than 3.50 then he/sheget the 50% waiver of the total fees. The rest of the student have to pay the total fees.Design a JAVA class “CurrentStudent” that can be used in the “Student” class as localinner class to rewrite the given function. Also implement the system in main methodwith appropriate objects.
c++ Implement a MyInt class. An object in the MyInt class must be able to hold a single dynamically allocated integer. MyInt should have the following members: A member variable ptr of type int *.A parameterized constructor that takes nums of type int as input parameters.A destructor.A superimposed assignment operator (). The copy must be deep.A function set that sets the value of the number.A function get that returns the value of the number.The members must be encapsulated in accordance with the convention. Memory leaks must be avoided. To test your class, create objects and call functions according to the comments below. All tests must be validated.

If a base class declares a pure virtual function, a derived class must implement thatfunction to become a concrete class. T/F
All virtual functions in an abstract base class must be declared as pure virtual functions T/F
(Enhanced Employee Class) Modify class Employee inFigs. 12.9–12.10 by adding a private utility function calledisValidSocialSecurityNumber . This member function shouldvalidate the format of a social security number (e.g., ###-##-#### , where # is a digit). If the format is valid, return true ;otherwise return false .
Define a member function PrintAll() for class PetData that prints output as follows with inputs "Fluffy", 5, and 4444. Hint: Make use of the base class' PrintAll() function.Name: Fluffy, Age: 5, ID: 4444 #include <string>using namespace std; class AnimalData {public: void SetName(string givenName) { fullName = givenName; }; void SetAge(int numYears) { ageYears = numYears; }; // Other parts omitted void PrintAll() { cout << "Name: " << fullName; cout << ", Age: " << ageYears; }; private: int ageYears; string fullName;}; class PetData: public AnimalData {public: void SetID(int petID) { idNum = petID; }; // FIXME: Add PrintAll() member function /* Your solution goes here */ private: int idNum;}; int main() { PetData userPet; string userName; int userAge; int userID; cin >> userName; cin >> userAge; cin >> userID; userPet.SetName(userName); userPet.SetAge…
Object Oriented Programing Consider the following details of all classes in diagram A person can be an employee or a student. An employee may have rights of admin officer or of academic officer. These class hierarchies represent multi-level inheritance. However, a Dean or Head of Department(HOD) may have rights to modify the status already defined by an administrator academic officer. Implement all these classes with appropriate data members and proper suitable functions and within the main function, create instances of all classes and test the described working of all these classes.
