- 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.Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add areference declarator (&) before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.objective of the project: Implement a class address. An address has a house number street optional apartment number city state postal code. All member variables should be private and the member functions should be public. Implement two constructors: one with an apartment number one without an appartment number. Implement a print function that prints the address with the street on one line and the city, state, and postal code on the next line. Implement a member function comesBefore that tests whether one address comes before another when the addresses are compared by postal code. Returns false if both zipcodes are equal. Use the provided main.cpp to start with. The code creates three instances of the Address class (three objects) to test your class. Each object will utilize a different constructor. You will need to add the class definition and implementation. The comesBefore function assumes one address comes before another based on zip code alone. The test will also return…

Write the code for these as inline functions.Write the declaration of a class Cylinder containing: A member variable height of type double. A member variable radius of type double. setHeight - a mutator function for the height member variable. setRudius - a mutator function for the radius member variable. getHeight - an accessor function for the height member variable. getRadius - an accessor function for the radius member variable. getVolume - a function that returns the volume of the Cylinder. getSurface - a function that returns the surface of the Cylinder. . . Notes: - Search online for the cylinder's volume and surface formulas - Consider 3.14 as the value of π (pi) - The main function the instructor will be using to test your Cylinder class is: } int main() { Cylinder tank; double CylinderHeight; double CylinderRadius; cout > CylinderHeight; cout > CylinderRadius; tank.setHeight (CylinderHeight); tank.setRadius (CylinderRadius); cout << "The volume is: " <<< tank.getVolume () <<<< endl; cout << "The surface is: " <<…
- 1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.Create a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape.Define two classes A and B each having one String private data member. Write zero argument and parameterized constructors to initialize the data member and member functions to get, set and display the data member for these classes. In the demo class, write a concat() function which takes the 2 arguments as class A and class B objects and concatenates the data ac members of these two objects. Write main method that creates instances of the classes A and B, assigns values to each and concatenates the value of data member of these objects using the concat() function. Display the objects before and after concatenation.
- Design 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…Consider the following definition of a class.class displayClass{public: void print(); ... private: int listLength; int *list; double salary;string name; } Part a. Write the function prototype to overload the assignment operator for the class displayClass. Part b.Write the definition of the function to overload the assignment operator for the class displayClass. Part c. Write the function prototype to include the copy constructor for the class displayClass. Part d. Write the definition of the copy constructor for the class displayClass.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.
