2.1 Wheels for Cars Let's first do wheels! 1. You need to define a Wheel class. At the moment, this class should have just a single variable state of type string. Make sure this variable is hidden from those outside the class! 2. Now, within this class, define a public function with the following declaration: void set_wheel_state(string s); This function should take set the state of the wheel to the value passed in as s. 3. Write another function in this class with the following declaration: string get wheel_state() This should simply return the state of the wheel. After this, you should be able to run Part - 3 of the main function in the starter file. 2.2 Cars on Wheels Once we have a Wheel class, we can use it within our Car class. 1. Define a new class Car. This should have an array of wheels- the size of the array should be 4 since we have only four wheels. Make sure this array is not visible from outside the class.

You must implement the pieces of the below classes on the following pages. You only should implement the functions that are underlined and followed by a "TODO: implement" comment. An example main function is provided to help you test your solution. You may assume the other functions have been implemented correctly, and you may use them. class Point { public: Point(); Point(double, double); double getX() const; double getY() const; void setX(double); void setY(double); void move(double, double); private: double xCoord; double yCoord; public: // output format: (x,y) void display() const; }; class Rectangle { public: Rectangle(); Rectangle(const Point &ll, double w, double h); Rectangle(const Point &ll, const Point &ur); // TODO: implement // Output format - LL:(x,y) W:width H:height void…
Add a member function having return type boolcalled isOversize( ) to the publication class. Let’s say that a publication is Oversized if it has pages more than 550. You can access this function from main() using the objects created and display the string “Oversized” or “Not Oversized” for oversize/not oversized publication. Use the return value of the function to display the specified string.(use if … else…).

... 5. Extend the Rectangle class by adding and implementing the special operator methods for the six relational operations (=, !-, , >=). The relational operators should logically compare the positions of two rectangles on the canvas by comparing the corresponding x- and y-coordinates. For example, the less than operator should determine whether the x- and y-coordinates of one rectangle are less than the x- and y-coordinates of a second rectangle. rectangle.py 1 class Rectangle : 2 #323 # Initializes a Rectangle object. # @param x the x-coordinate for the upper-left corner of the rectangle # @param y the y-coordinate for the upper-left corner of the rectangle # éparam width the width of the rectangle # éparam height the height of the rectangle 3 4 5 6 8 9 10 11 12 13 _init_(self, x, y, width, height): self._x = x self. y = y self. width = width self._height = height def 14 def lt (self, rhs): 15 16 17 18 19 20 ... # Include the new special operator methods here. 21
Using c++ programming language. Write a class Distance that holds distances or measurements expressed in feets and inches. Thisclass has two private data members: feet: An integer that holds the feet. inches: An integer that holds the inches. Write a constructor with default parameters that initializes each data member of the class.If inches are greater than equal to 12 then they must be appropriately converted tocorresponding feet. Generate appropriate getter-setter functions for the data members.o void setFeet(int f) and int getFeet()consto void setInches(int i) It should ensure proper conversion to feet.o int getInches() const Define an operator ‘+’ that overloads the standard ‘+’ math operator and allows oneDistance object to be added to another.

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.
All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.
Create a time class having data members hour, minute and second. Make a constructor to set the members zero, make a display function that outputs the time in given format: 00:00:00. Make a function called ticktick() that increments the time in such a way that hour do not change till the minutes and seconds ends at 60. (01:01:01…. 01:59:59 -> 02:00:00). Design the main function, create an object and call the functions accordingly.
C++ is a programming language that can be used to Make a program that calculates the volume of different containers. Cylinder will be the base class, and its derived classes, also known as child classes or sub-classes, will be constructed. Create a parent class, Cylinder, first. Make a constant for pi, as you'll need it for any containers that aren't square. For the members, use protected. Finally, add a public function to control the volume. V= pi * (r2) * h is the formula.
Using Python, create 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) hint: apply "classes" concept
write a class Point with parametrized constructor. This class have four member variables, a,b,c,d. Write the following member functions a. drawTriangle(int x, int y, int z ) b. drawRectangle(int x, int y, int z, int a). Each function should display the length of lines for each of the shape (triangle, rectangle). For example triangle should calculate length of its three lines by following methods as shown in code. Note: the number of lines depends on the name of shape. void drawTriangle(int x, int y, int z ) { int line 1 = x - y; // convert to positive value if line length is negative int line 2 = y -z; int line 3 = z -x; cout<< The length of each lines is: << //// here display length of each line with proper formatting. } Write similar code for drawRectangle(int x, int y, int z, int a). Wtite main function to call these three function
