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.

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.
c++ Implement a BankAccount class. BankAccount must have the following members: A member variable account_no of the type unsigned int.A member variable owner_name of type std :: string.A member variable balance of the double type.A parameterized constructor that takes account_no and owner_name as input parameters.The members must be encapsulated in accordance with the usual convention. Overlay the inflow operator (>>) for the BankAccount class Input follows the format:[account_no] [owner_name] [balance] and must be loaded with the inflow operator. Output should have the following format:Account [account_no], owned by [owner_name] has the balance [balance] Note that the square brackets refer to variables or special characters and are not included.You may add necessary designers, member functions and operators at will as long as they are appropriate. input expected output123 Hansson 1000 Account 123, owned by Hansson has the…
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.

Problem: Create a Fraction class with two private positive integer member variables numerator and denominator, one constructor with two integer parameters num and den with default values 0 and 1, one display function that print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4 should be displayed as ½.

writte in c++ Write a Circle class that has the following member variables: • radius : a double • pi : a double initialized with the value 3.14159 The class should have the following member functions: • Default Constructor. A default constructor that sets radius to 0.0. • Constructor. Accepts the radius of the circle as an argument. • setRadius. A mutator function for the radius variable. • getRadius. An accessor function for the radius variable. • getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius
- Implement the class “cylinder” with member variables radius and height, whichare private of type double. Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…
For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…
In c++, define a class for a type called Counter . An object of this type is used to count things. Include a default constructor that sets the counter to zero and a constructor with one argument that sets the counter to the valuespecified by its argument. Write member functions to increase the value by one (called increment ) and decreasethe value by one (called decrement ), don’t let the value go below 0. Write a member function ( print ) that printsout the value of the counter.Here’s a driver program that you should include to test your class.
