- 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.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.Model a room class, whose member data is three integers length, width and height. The classcontains two constructors to initialize the room class objects, first is no argumentconstructor, while the second in three arguments constructor. Class also contains threemember functions i.e., getdatat) to get the data from user and store in the memory of callingobject and showdata) to show the room data of calling object, int volume(int I, int w, int h)function should receive the length, width and height values from the objects one by one andreturn the volumes of the three objects respectively.Write a main program to declare the three object rl, 12, and 13 of room class. Two objectwill store the values through three argument constructor and third object will get the datafrom user by calling getdata function. Then all three objects should call the volumefunctions to calculate their volumes and store them in three variables of type integer. Finallythe system compare the three volumes values…
- Q1) Write the Code the following scenario. Write an abstract function named receivePay in interface with return type double and no parameters. Write another incomplete function, name Show with return type void and an argument of type int in that interface. Build a class with name Bill that implements the above interface. Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface? NOTE:SUBJECT:CSHARP (VISUAL PROGRAMMING)write the definition of the class Rectangle containing: length: a private data member of type double width: a private data member of type double a default constructor that assigns the values 20 and 10 length and width, respctively. an overloading constructor that accepts two parameters of type double and assigns them to length and width. an overloading constructor that accepts one parameter of type double and assigns it to both length and width setLength: a member function that accepts a double parameter and assigns it to length if it is positive(gerater than zero). setWidth: a member function that accepts a double parameter and assigns it to width if it is positive(gerater than 0) getLength: a member function that accepts no parameter and returns the value of length getWidth: a meber function that accepts no parameters and returns the value of width getAre: a member function that accepts no parameters and returns the area of the rectangle.a c++ program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Modify the above classes and provide overloaded constructor implementation for each class. (Note: Use base initialize for this purpose) Note: Solve as soon as possible use oop concepts
- Define a class for complex numbers. A complex number is a number of the form a + b*i where for our purposes, a and b are numbers of type double, and i is a number that represents the quantity √-1. Represent a complex number as two values of type double. Name the member variables real and imaginary. (The variable for the number that is multiplied by i is the one called imaginary.) Call the class Complex. Include a constructor with two parameters of type double that can be used to set the member variables of an object to any values. Include a constructor that has only a single parameter of type double; call this parameter realPart and define the constructor so that the object will be initialized to realPart + 0*i.Include a default constructor that initializes an object to 0 (that is, to 0 + 0*i).Overload all the following operators so that they correctly apply to the type Complex: ==, +, −, *, >>, and <<. You should also write a test program to test your class. Hints: To add…Consider a base class named Employee and its derived classes HourlyEmployee and PermanentEmployee while taking into account the following criteria.• Employee class has two data fields i.e. a name (of type string) and specific empID (of type integer)• Both classes (HourlyEmployee and PermanentEmployee) have an attribute named hourlyIncome• Both classes (HourlyEmployee and PermanentEmployee) have three-argumentconstructor to initialize the hourlyIncome as well as data fields of the base class• Class HourlyEmployee has a function named calculate_the_hourly_income to calculate the income of an employee for the actual number of hours he or she worked. One hour income is Rs. 150 • Similarly, PermanentEmployee class has function named calculate_the_income to calculate the income of an employee that gets paid the salary for exact 240 hours, no matter how many actual hours he or she worked. Again, one hour salary is Rs. 150.Implement all class definitions with their respective constructors to…Experiment with two classes that have a straightforward derivation relationship. Insert println statements into the constructors of both the parent and child classes. In the child, do not explicitly call the function Object() { [native code] } of the parent. So, what happens? Why? Change the child's function Object() { [native code] } to explicitly call the parent's function Object() { [native code] }. What happens next?
- Write a program to model a student class with roll number and name as the sensitive information. Initialize default values for the sensitive information using a default constructor, use a copy constructor to copy from another object, use a member function to take user input and update the name and roll number and display the same using another member function. b.Add constructor overloading to the above code and enable initialization of name, roll number via constructor arguments. NAME ROHI ROLLNO 18Write a program in the C++ language to create a class Rectangle with two member integer variables length and breadth. Write the parameterized constructor for the class and also add a member function that displays the area of the rectangle in the output.Create a base class named Point consisting of x and y data members representing point coordinates. From this class, derive a class named Circle with another data member named radius. For this derived class, the x and y data members represent a circle’s center coordinates. The member functions of the Point class should consist of a constructor, an area() function that returns 0, and a distance() function that returns the distance between two points,(x1,y1) and (x2,y2), where Additionally, the derived class should have a constructor and an override function named area() (PI*pow(radius,2)) that returns a circle’s area. Task: 1-Include the classes constructed in a working C++ program. 2-Have your program call all the member functions in each class. 3- In addition, call the base class’s distance() function with two circle objects and explain the results this function returns.
