Question
I need you to write me the answers on paper.
For 1. Expand in two object universe (the objects are named ‘a’ and ‘b’)
For part 2. Indicate which variables are free and which are bound ( you can use ‘F’ for free and ‘B’ for bound). Either (i) draw a vertical line underneath each variable with the letters ‘F’ or ‘B’ at the bottom of each vertical line or (in) color bound variables red and free variables green.

- Create a UML diagram to document the Cuboid class. You can model this class after the Rectangle class we covered in this chapter. It should have 3 data fields: width, length, height. It should have 3 accessors and 3 mutators. It should have a method that calculates the volume of the cuboid. Save your file in MS Word or PDF format. Hint: In MS Word, you can create a table of 1 column and 3 rows. What is a cuboid? You can consider a cuboid as a cube whose length, width, and height may not be equal to each other.arrow_forwardDevelop the code that would be used in the main() function to test the class Cube. Create an object of Cube type using the constructor with argument, with the name of "Box", side length of 5, and color "Brown". Print out the information for the Cube.

This function expects a Turtle object, a pair of integers that indicates the coordinates of the square’s upper left corner, and an integer that designates the length of aside. The function begins by lifting the turtle up and moving to the square’s corner point. It then points the turtle south at 270 degrees and places the turtle pen down on the drawing surface. Finally, it moves the turtle to the given length and turns it left 90 degrees four times. here's what I have with a circle assignment I have done but building off from that. Any assistance would be greatly appreciated. import mathfrom turtle import Turtle, tracer, update print("\n-------Circle-------") def drawCircle(t, x, y, radius): """Draws a line segment between the endpoints.""" t.up() t.goto(x + radius, y) t.setheading(90) t.down() t.pencolor("blue") t.fillcolor("red") t.begin_fill()…arrow_forward

The Tourtise and The Hair In this lab, we will be simulating the classic race of the tourtise and the hare. The race will take place on two paths of 70 tiles, which spans from left to right. The path will have two lanes, one for each animal. The path will be represented as an array of 70 characters, where each character will be the following: · A dash(i.e, “-“), which represents an empty tile. · An “h”, which represents the hare on the hare lane. · A “t”, which represents the tourtise on the tortise lane. All tiles will be “empty” (i.e. set to the dash) with the exception of the tiles that are occupied by the animals. As the animals move, the previous tile the animal was on will be set to empty, and the new tile will be changed to either “h” or “t”. Tile 70 will be the finishing tile, and the first animal to that tile will be declared the winner of the race. We will use randomization to determine how far each animal will move. Since this race will be…arrow_forward
- For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }arrow_forwardCreate the VisualCounter class, which supports both increment and decrement actions. Take the function Object() { [native code] }'s two arguments N and max, where N specifies the maximum action number and max specifies the counter's maximum absolute value. Make a plot that displays the worth of the counter each time its tally changes as a byproduct.arrow_forwardDeclaring a variable with only "type" is sufficient. The data type and other characteristics of a variable may be used to locate it. The next step is to figure out how to use this framework to describe any variable.arrow_forward
