- B)Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the same.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…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.
- Suppose you are working on a project managing the bus fare of Dhaka metropolitan city. At this point you are designing a vehicle class(choose if you need to define it as an abstract class, interface or concrete class). After that, you need to create different classes such as Bus, Double_Decker_Bus, Mini_Bus, Regular_Bus and all of these classes will extend the Bus class. You are free to define the classes as you deem necessary. In the driver class, you must be able to call methods to print the bus fare per kilometer for double_decker bus, regular bus and mini bus(the fare should be different). You also need to calculate the bus fare of a route based on user input(in kilometers) to display the total bus fare for a single person. Adding to this, you will be able to calculate student fare based on the availability of the student ID card.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)a.) Write the definition of the default constructor of YClass so that the instance variables of YClasa are initialized to 0. b.) Write the definition of the default constructor of XClass so that the instance variable of XClass are initialized to 0. c.) Write the definition of the method two of YClass so that rhe instance variable a is initialized to the value of the first parameter of two, and the instance variable b is initialized to the value of the second parameter of two.
- Which of the following statements are true. a) An abstract method contains a signature but no code implementation. b) We cannot create an instance of an abstract class by using the new operator. c) We can derive classes from an abstract class, but we must provide code to implement all of the abstract methods. d) All of the above statements are true.When would you be most likely to use an abstract class? when you need to derive a class from Object when every method in the class is concrete when you need a super class that should not be instantiated when you need a super class that can be instantiated alongside the derived classes =========== Which UML symbol represents aggregation? a filled triangle an unfilled diamond an unfilled triangle a filled diamondCreate a program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p)
- This is a polymorphism assignment I can't seem to figure out for Java Create an abstract class named Shapes. The Shapes class has only the calcArea() method. From Shapes, create three derived classes named Circle, Square and RightTriangle. Each of the three should have data members used to calculate the area of its shape. Define the method calcArea() for each of the three shapes. Each of the three shapes should also have appropriate constructors. Not required, but create a class with the main() method to test the classes created above.Answer the given question with a proper explanation and step-by-step solution. C++ Virtual Methods Create the following 3 classes: 1. AppWindow class, containing: - A protected instance of a rectangle class Rect defining the AppWindow's position (x,y) and size (w,h). (You may use the Rect class you developed in the previous lab. In main(), the width and height are assumed to be public and called "w" and "h".) - The following constructors to initialize the dimensions: AppWindow(); // initialize member rect's dimensions to 0AppWindow( float x, float y, float w, float h ); // initialize member rect's dimensions with the 4 floatsAppWindow( const Rect& r ); // initialize member rect's dimensions with r's dimensions - A method to retrieve the member rectangle: const Rect& get_rect(); - A virtual method called resize(). When this method is called, your implementation is supposed to change the dimensions of the internal rectangle of the window. virtual void resize( int w, int h ); 2.…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.
