Write a program that teaches arithmetic to a young child. The program tests addition and subtraction. In level 1 it tests only a

ddition of numbers less than 10 whose sum is less than 10. In level 2 it tests addition of arbitrary one-digit numbers. In level 3 it tests subtraction of one-digit numbers with a nonnegative difference. Generate random problems and get the player input. The player gets up to two tries per problem. Advance from one level to the next when the player has achieved a score of five points.

Answer:

import random

class Arithmetics(object):

   trial = 2

   score = 0

   is_end = "Y"

   

   def start(self):

       while self. is_end == "Y":

           self. level1()

           self. level2()

           self. level3()

           self. is_end = input("Do you want to play again? Y/N: "). upper()

       quit()

   def level1(self):

       print("--------------------Level 1--------------------\n\n Addition:")

       for _ in iter(list, 0):

           num1 = random.randint(1,5)

           num2 = random.randint(1,5)

           if self. score == 5:

               print("Congrat! advance to next level\n")

               self. init_()

               break

           print(f"{num1} + {num2}")

           result = int(input("Your answer: "))

           if result == num1 + num2:

               self. increase_score()

           elif self. trial == 0:

               print("Sorry dear, you failed to pass the text.")

               self. end_game()

           else:

               self. trial_reduce()

   def level2(self):

       print("--------------------Level 2--------------------\n\n Addition again:")

       for _ in iter(list, 0):

           num1 = random. randint(1,9)

           num2 = random. randint(1,9)

           if self. score == 5:

               print("Congrat! advance to next level\n")

               self. init_()

               break

           print(f"{num1} + {num2}")

           result = int(input("Your answer: "))

           if result == num1 + num2:

               self. increase_score()

           elif self. trial == 0:

               print("Sorry dear, you failed to pass the text.")

               self. end_game()

           else:

               self. trial_reduce()

   def level3(self):

           print("--------------------Level 3--------------------\n\n Subtraction:")

           for _ in iter(list, 0):

               denum = random. randint(6,9)

               num = random. randint(1,5)

               if self. score == 5:

                   self. init_()

                   self. end_game()

                   break

               print(f"{denum} - {num}")

               result = int(input("Your answer: "))

               if result == denum - num:

                   self. increase_score()

               elif self. trial == 0:

                   print("Sorry dear, you failed to pass the text.")

                   self. end_game()

               else:

                   self. trial_reduce()

   #classmethod

   def trial_reduce(cls):

       cls. trial -= 1

   #classmethod

   def increase_score(cls):

       cls. score += 1

   #classmethod

   def init_(cls):

       cls. trial = 2

       cls. score = 0

   def end_game(self):

       print("Congrats kiddo! You are a math wiz.")

game = Arithmetics()

game. start()

Explanation:

The python class defines the arithmetics class with three-level mathematics for children defined as methods for the class. There are three class methods namely; 'trial_reduce', 'increase_score', and 'init_' with each of them decreasing the trial attribute, increasing the score attribute by one, and initializing the class attributes to its initial state.

The 'end_game' prints a message at the end of the program. Each level is in a loop and counts five times if the answers are correct.

The 'client area' of a window is the area used to display the contents of the window (thus a title bar or border would lie outsi
Lady_Fox [76]

Answer:

<u>Window.java</u>

  1. public class Window {
  2.    int width;
  3.    int height;
  4.    public Window(int width, int height){
  5.        this.width = width;
  6.        this.height = height;
  7.    }
  8.    public int getWidth(){
  9.        return width;
  10.    }
  11.    public int getHeight(){
  12.        return height;
  13.    }
  14.    public int getClientAreaHeight(){
  15.        return getHeight();
  16.    }
  17. }

<u>Main.java</u>

  1. public class Main {
  2.    public static void main (String [] args) {
  3.        Window win1 = new Window(12, 15);
  4.        System.out.println(win1.getClientAreaHeight());
  5.    }
  6. }

Explanation:

<u>Window.java</u>

There is a Window class with two int type attributes, width and height (Line 1 - 3).

The constructor of this class will take two inputs, width and height and set these input to its attributes (Line 5 - 8). There are two methods getWidth and getHeight which will return the value of attributes width and height, respectively (Line 10 - 16).

The required new method getClientAreaHeight is defined in line 18 -20. This method will call the getHeight method to return the height value of the window (Line 19).

<u>Main.java</u>

We test the Window class by creating one Window instance and call the getClientAreaHeight method and print the return output (Line 1 -6).

We shall see 15 is printed.

LAB: Formatted output: Hello World! Write a program that outputs "Hello World!" For ALL labs, end with newline (unless otherwise
maxonik [38]

Answer:

public class LabProgram {

  public static void main(String[] args) {

     System.out.println("Hello World!");    }  }

Explanation:

In this statement: System.out.println

System is a class in JAVA language package

out is a member of class System

println() is a functionT to print or display message to a console or file

So the message to print here is Hello World!

Now this statement   System.out.println prints the message "Hello World!" passed in the argument.

Hence this statement as a whole displays the message Hello World! on the output screen.

The fast movement of briefly flashed images in an animated motion picture produces what effect? subliminal messaging convergence
REY [17]

Answer:

The answer is Stroboscopic movement

Explanation:

Stroboscopic movement occurs when we do not see a motion continuously but in discrete shots. It is an effect in which we see an object at one place and after another instant the object seems to have shifted it's position.

Auto kinetic effect is an effect in which a stationary point of light appears to move.It occurs as our brains can perceive motion relative to some other object and cannot observe ,motion along a featureless terrain or environment.

Phi effect causes an observer to perceive motion in stationary objects.

alexandr1967 [171]

Answer:

c. Attribute constraints

Explanation:

A data catalog identifies all of the following, except: "Attribute constraints"

The above statement is TRUE because a Data Catalog, a metadata management service, operates by searching for key data, understand and manage data for usefulness.

Data Catalog checks on the BigQuery datasets, tables, and views and checks both technical and business metadata by identifying the following attributes:

1. Data type

2. Range of values

3. Value for Instructor ID
