Program Plan Intro

Program to displays the score with each click and the total score in series

Program plan:

  • Import the required packages
  • In the “main()” function,
    • Create the object of “GraphWin()”.
    • Set the coordinates by calling the function “setCoords()”
    • Create an object named “c” and store the points
    • The outline of the circle is set to “green4” color.
    • The circle is filled with “white” color.
    • The width of the circle is set with the use of function “setWidth()”.
    • Draw the circle with the use of function “draw()”.
    • Create an object named “c2” and store the points
    • The outline of the circle is set to “green4” color.
    • The circle is filled with “red” color.

      • Derive the x-coordinate with the use of “getX()” function.
      • Derive the x-coordinate with the use of “getY()” function.
      • Calculate the value derived out of the equation and store in “z”.
      • If the z-value is less than or equal to 5 and greater than 4 then,
        • “y” is assigned with “1”
        • “sum” is added with the value of “y”.
      • If the z-value is less than or equal to 4 and greater than 3 then,
        • “y” is assigned with “3”
        • “sum” is added with the value of “y”.
      • If the z-value is less than or equal to 3 and greater than 2 then,
        • “y” is assigned with “5”
        • “sum” is added with the value of “y”.
      • If the z-value is less than or equal to 2 and greater than 1 then,
        • “y” is assigned with “7”
        • “sum” is added with the value of “y”.
      • If the z-value is less than 1 then,
        • “y” is assigned with “9”
        • “sum” is added with the value of “y”.
      • otherwise,
        • “y” is assigned with “0”
        • print the output statement.
        • Print the value stored in “y” and “sum”.
  • Call the function “main()”.

Program Description Answer

This program displays score achieved with each click in an archery board and also calculates and displays the sum of the entire series of outputs.

Explanation of Solution

Program:

#import the required packages

from graphics import *

import math as m

#define the main() function

def main():

    #declare the required variables

    win = GraphWin()

    #set the coordinates

    win.setCoords(-5, -5, 5, 5)

    #draw the circle with specified points

    c = Circle(Point(0,0), 5)

    #set the outline of the circle

    c.setOutline("green4")

    #fill the circle with the colour

    c.setFill("white")

    #set the width of the circle

    c.setWidth(1)

    #draw the circle

    c.draw(win)

    #draw the circle with specified points

    c2 = Circle(Point(0,0), 4)

    #set the outline of the circle

    c2.setOutline("green4")

    #fill the circle with the colour

    c2.setFill("red")

    #set the width of the circle

    c2.setWidth(1)

    #draw the circle

    c2.draw(win)

    #draw the circle with specified points

    c3 = Circle(Point(0,0), 3)

    #set the outline of the circle

    c3.setOutline("green4")

    #fill the circle with the colour

    c3.setFill("blue")

    #set the width of the circle

    c3.setWidth(1)

    #draw the circle

    c3.draw(win)

    #draw the circle with specified points

    c4 = Circle(Point(0,0), 2)

    #set the outline of the circle

    c4.setOutline("green4")

    #fill the circle with the colour

    c4.setFill("black")

    #set the width of the circle

    c4.setWidth(1)

    #draw the circle

    c4.draw(win)

    #draw the circle with specified points

    c5 = Circle(Point(0,0), 1)

    #set the outline of the circle

    c5.setOutline("green4")

    #fill the circle with the colour

    c5.setFill("white")

    #set the width of the circle

    c5.setWidth(1)

    #draw the circle

    c5.draw(win)

    #declare and initialize the variable

    sum = 0

    #initialize the loop for x less than 5

    for x in range (5):

        #get the locations where mouse is clicked

        arrow = win.getMouse()

        #stores the X coordinate

        x = arrow.getX()

        #stores the Y coordinate

        y = arrow.getY()

        #calculate and store the value

        z = m.sqrt(x ** 2 + y ** 2)

        #condition for z to be less than or equal to 5 and greater than 4

        if 5 >= z > 4:

            #declare the variable

            y = 1

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 4 and greater than 3   

        elif 4 >= z > 3:

            #declare the variable

            y = 3

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 3 and greater than 2      

        elif 3 >= z > 2:

            #declare the variable

            y = 5

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than or equal to 2 and greater than 1      

        elif 2 >= z > 1:

            #declare the variable

            y = 7

            #calculate the value of sum

            sum = y + sum

        #condition for z to be less than 1     

        elif 1 > z:

            #declare the variable

            y = 9

            #calculate the value of sum

            sum = y + sum

        #else statement   

        else:

           #declare the variable

            y = 0

            #print the statement

            print("You missed!")

        #print the statement

        print("Point: {0}    Total: {1}".format(y, sum))

#call the main() function

main()

Using the following execution shown below, explain what is done in each of the ARIES recovery algorithm phases: LSN   LOG 00   begin_checkpoint 10 end_checkpoint 20 update: T1 writes P1 30 update: T2 writes P2 40 update: T3 writes P3 50 T2 commit 60 update: T3 writes P2 70 T2 end 80 update: T1 writes P5 90 T3 abort   CRASH, RESTART In addition to the execution shown here, the system crashes during recovery after writing two log records to stable storage and again after writing another two log records
A new application is being developed and will be using a database that includes a relation about items: Item (item_id:integer, item_name:string, color:string, price:real). Both the purchasing department in charge of obtaining raw material and the manufacturing department in charge of manufacturing the items can change the price of manufactured items according to changes that may happen in the raw material cost or production cost. The two departments use different transactions to update the price of items. The new application uses the following sequences of actions, listed in the order they are submitted to the DBMS: Sequence S1: T1:R(X), T2:W(X), T2:W(Y), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit Sequence S2: T1:R(X), T2:W(Y), T2:W(X), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit For each of the following concurrency control mechanisms, describe how they will handle each of the sequences (S1 & S2). Strict 2PL with timestamps used for deadlock prevention. Conservative…
As a database administrator of a large manufacturing organization, you are in charge of their website database that handles suppliers, parts, catalog, customers, and payments of delivered items. The following relations are part of the large database: Supplier(SID, Sname, Saddress, Stelephone)Customer(CID, Cname, Caddress, Ctelephone)Part(PID, Pname, Pmodel, Pcolor)Catalog(SID, PID, Price) (The Catalog relation lists the prices charged for parts by Suppliers). Because the application is web-based and the database is accessed by many users, you want to increase the concurrency usage without compromising the data quality. For each of the following transactions, state the minimum SQL isolation level you would use in order to avoid any conflict problems in them. Please explain your choice. A transaction that adds a new part to a supplier’s catalog. A transaction that increases the price that a supplier charges for a part. A transaction that determines the total number of items for a given…
