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.
In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
A class Student has Roll No, Branch, class Internal_exam has sub1marks, sub2 marks, class External_exam has sub1marks and class Result has Total as data members. Write necessary member functions to input and print data. (i) Calculate Internal_exam and External_exam subtotals using their respective member functions.(ii) Class Result has a function to calculate Total=internal+ external subtotals. Write a complete program to implement the hierarchy of the classes using virtual base class.
The base class Pet has protected data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. Ex. If the input is: Dobby2Kreacher3German Schnauzer the output is: Pet Information: Name: Dobby Age: 2Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer #include <iostream>#include<string>#include "Dog.h" using namespace std; int main() { string petName, dogName, dogBreed; int petAge, dogAge; Pet myPet; Dog myDog; getline(cin, petName); cin >> petAge; cin.ignore(); getline(cin, dogName); cin >> dogAge; cin.ignore(); getline(cin, dogBreed); // TODO: Create generic pet (using petName, petAge) and then call PrintInfo //…
(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 .
Write a program to create a base class: “Question3”, with protected data member: x (int) and with pure virtual function: “Task ()” [Returns no value and takes no argument]. Create a derived class of “Question3” such as “Sub1” (Derive features in public mode). In sub1, there is a member function in public section: get_data1 () to take input for x, and define Task () in this class to display the factorial of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions]. Write the program in c++ language.
Create a class: Doctor, with private data members: id, name, specialization and salary with public member function: get_data () to take input for all data members, show_data() to display the values of all data members and get specialization () to return specialization. Write a program to write for detail of n doctors by allocating the memory at run time only.c++
Write a base class Computer that contains data members of wordsize(in bits), memorysize (in megabytes), storagesize (in megabytes) and speed (in megahertz). Derive a Laptop class that is a kind of computer but also specifies the object’s length, width, height, and weight. Member functions for both classes should include a default constructor, a constructor to inialize all components and a function to display data members
WRITE A PROGRAM IN C++ Create a Circle class with a centre (x,y) and radius r. Use parameterized constructor to initialize the radius and centre of a circle object. Write a copy constructor that copies the values of one circle object to another one. Use a member function to display the values x,y,r of a circle object. Allow a friend function to update the centre and radius of the circle. There should a static variable 'number_of_circles' and a static member function 'update_number_of_circles' which will update the 'number_of_circles' whenever an instance of a circle is created.

Consider a base class Employee which contain basic information of an employee such as:Name(string)Address(string)Id(int)Gender(string)Now create two constructors A default constructor to initialize the data member with default values, A four-argument constructor to initialize data field with user-define values ( must use this key word). Getter and setter function to set and get values of data fields.Derives two classes to show Hierarchical inheritance.A department class which extends the base class employee also have some its own information such as:Department Name(string)Department Id(int).Now create two constructors a default constructor to initialize the data member with default values, a parameterized constructor to initialize data field with user-define values. Appropriate getter and setter function to set and get values of data fields. A display method to show all the records of employee along with department information.Create another child class Loan which extends the base…
Write a program that declares two classes. The parent class is called Base that has two data members a and b to store two numbers. It also has two member functions: • The mul() function multiply two numbers and displays the result. • The div() function divides two numbers and displays the result. The derived class is called child class that overrides all two functions. Each function in the derived class checks the values of data members. It calls the corresponding member function in the parent class if the values are greater than 10. Otherwise it displays error message.
