Write a base class Computer that contains data members of wordsize (in bits), memory size in megabytes, and storage size in megabytes and speed in megahertz. Drive a Laptop class that is 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 initializes all components and a function to display data members.

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.
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 class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.
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…

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.
Example 10-10 defined a class personType to store the name of a person. The member functions that we included merely print the name and set the name of a person. Redefine the class personType so that, in addition to what the existing class does, you can: Set the first name only. Set the last name only. Store and set the middle name. Check whether a given first name is the same as the first name of this person. Check whether a given last name is the same as the last name of this person.
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…
Given the following class declaration (with prototypes): class Carpet { private: double pricePerSqYd; public: Carpet(); void setPricePerYd(double p); void setDimensions(double l, double w); double getTotalPrice() const; }; Assume the class Carpet has been implemented.
