Visual Basics 2015 The local smoothie store, Smoothie Queen has hired you to develop a program that will make it easier for their sales associates to compute a customer's bill. You are to write a program that will allow the cashier to enter in customer information, smoothie information and display the total amount due. Here are the pertinent details: CALCULATIONS: 1. COST OF A SMOOTHIE: The actual cost of the smoothie is based on the smoothie size and the smoothie style. See the table below for price information. Internally you can handle this in one of two ways – you can either store this in a two-dimensional array/table or you can use an array of structures with two fields like you did in the state/abbreviation program. Small Medium Large King Regular 5.99 6.99 7.99 8.99 Organic 6.99 7.99 8.99 9.99 There are two different ways to approach the needed programming for the smoothie prices. You can use either of these – whichever one makes the most sense to you. My personal approach would be the first one (two dimensional arrays) because the data lays out like an Excel spreadsheet so it’s easy to think in rows and columns. But many people would also take the second approach (array of structures): A. Two-Dimensional Array Approach: If you are going to use a 2 dimensional array/table, you could declare it using something like this at the top of your program near your constants: decimal[,] smoothieListDecimal = {{ 5.99M, 6.99M, 7.99M, 8.99M }, { 6.99M, 7.99M, 8.99M, 9.99M }}; In this setup the cost for a particular smoothie would be based on a row and column of the table. For example, smoothieListDecimal [0, 3] would contain the price of a Regular King Smoothie. You will be able to use the selectedIndex for each of the dropdown lists to determine the row and column you need. TIP: You do not need a loop to search for the correct smoothie price. You only need to know the selectedIndex values for the row (smoothie style) and column (smoothie size) B. Array of Structures Approach: A different approach would be to use an array of structures. If you are going to use an array of structures, you could use a similar setup to the state/abbreviation program with the fields being regularDecimal and organicDecimal. You would then need an array of 4 structure elements (for each size) that you would initialize in the form load. 2. SMOOTHIE EXTRAS: A customer can order one or more extras for their smoothie. Toppings are $0.75 each (use a constant) and will be one of the following:  Echinacea  Bee Pollen  Energy Booster 3. DISCOUNTS: A customer may receive a discount on their purchase. Discounts are computed before taxes and can be one of the following (use a constant):  None – no discount  Preferred customer card - 15% discount  Coupon - 10% discount 4. TAXES: The final bill should also add in a state sales tax of 8% before calculating the amount due. You should incorporate a METHOD / FUNCTION to compute the tax. 5. CONSTANTS: Use appropriate constants for all numerical values that are predefined (e.g., extras, tax, discounts). FORMS SPECIFICATIONS AND VALIDATION 1. ABOUT FORM: Your program should have an “About” form that contains the typical information (program name, date, author, etc.). See sample EXE. 2. MAIN FORM (Customer Data): This form will need several components. There are also several required fields that should display appropriate error messages. When in doubt, refer to the sample EXE or post a question on the discussion board. 3. TEXT BOXES: You will use textboxes for the customer information. All fields must contain information or an error message will be displayed. • Customer Name TIP: You do not need to use a Try/Catch to do all the data validation since these are not numeric text fields. You can use a nested IF/ELSE setup to test the fields for the required input to make sure they are not blank. 4. COMBO BOXES/DROPDOWN LISTS • Smoothie Size: Should be one of the following – small, medium, large or king. Selection required. A size must be selected or an error should appear. Hint: Check to ensure the selectedIndex <> -1. • Smoothie Style: Should be one of the following – regular or organic. Selection required. A style must be selected or an error should appear. Hint: Check to ensure the selectedIndex <> -1. 5. CHECKBOXES/GROUPS: • Extras: Can be none, or, one or more of the following: Echinacea, Bee Pollen and Energy Booster. 6. RADIO BUTTONS/GROUPS: • Discount: May be none or 10% coupon or preferred customer (15% discount). 7. PULL DOWN MENUS (EXTRA CREDIT): The menu system should contain the following options (you can organize the menu choices however you’d like): • Calculate - Totals the customer's bill after adding any extras, deducting discounts and adding appropriate tax (assuming all data validation tests are passed). Displays the subtotal, discount, tax and amount due in the label box as currency. Note that if any validation error occurs, the program should not calculate or display any totals. • Clear - Clears all the text, check and option buttons, and totals. Repositions the cursor in the customer name text box for the next customer. • Help/About – Message box with your name and program name. • File/Exit - Exits the program. I have seen this posted before but wanted to see if someone would be able to explain more and possibly post screenshots of the code. Thank you in advance!

PYTHON: Turtle Command Interpreter

You will write a program that reads a sequence of codes, converts them into Turtle commands, and then executes them. The codes are in a Python list, passed as an argument to your function.

turtleRunner(t, x)
t is a Turtle
x is a list of Turtle commands

For example [("f", 100), ("r", 30), ("c", "red"), "u", ("f", 50), ("r", 60), "d", ("f", 100)] will execute:

t.forward(100)
t.right(30)
t.color("red")
t.penup()
t.forward(50)
t.right(60)
t.pendown()
t.forward(100)

Your program will need to do the following:

1. Define a function named turtleRunner(t, x), where t is a turtle and x is a list
2. Go through each element of x one at a time.
3. If the element is a tuple (if isinstance(e, tuple)):
   1. Determine if the code is f, r, c, or w
   2. Execute the correct turtle command using the second part of the tuple (a distance or color)
4. If the element is a string (if isinstance(e, str)):
   1. Execute the correct turtle command

x = [("w",3),("c","red"),("f",100),("r",120),("c","blue"),("f",100),("r",120),("c","green"),("f",100)]
turtleRunner(t, x)

Draws the shape below:

isinstance(x, y) returns True if x is an instance of class y. So isinstance(e, tuple) will return True if e is a Tuple.
(Note no quotes around tuple in the call)

isinstance(e, str) will return True if e is a String.

Starter code(please by off this):

# Tkinter
#
# Turtle Command Interpreter
#
# You will write a program that reads a list of codes, converts them into Turtle commands, and then executes them.
#
# Code list:
# (f, d) Move forward by d pixels
# u         Up
# d         Down
# (l, d)    Turn left by d degrees
# (r, d)    Turn right by d degrees
# (c, s)    Change color to "s"
# (w, d)    Change width to d
#
# Example:
# [("f", 100), ("r", 30), ("c", "red"), "u", ("f", 50), ("r", 60), "d", ("f", 100)]
#
# This will execute:
# t.forward(100)
# t.right(30)
# t.color("red")
# t.penup()
# t.forward(50)
# t.right(60)
# t.pendown()
# t.forward(100)
#
# Your program will need to do the following:
# 1) Define a function named turtleRunner(x), where x is a list
# 2) Go through each element of x one at a time.
# 3) If the element is a tuple (if isinstance(e, tuple)):
#    a) Determine if the code is f, r, or c
#    b) Execute the correct turtle command using the second part of the tuple (a distance or color)
# 4) If the element is a string (if isinstance(e, str)):
#    a) Execute the correct turtle command
#
import turtle

def turtleRunner(t, x):
    pass

w = turtle.Screen()
t = turtle.Turtle()
x = [("w",3),("c","red"),("f",100),("r",120),("c","blue"),("f",100),("r",120),("c","green"),("f",100)]
turtleRunner(t, x)

the Unix/Linux commands

1. Enter the “date” command to print the current date and time. Also, try the “cal” command.
2. Enter the command “clear” to clear the screen.
3. Use the command “cat .bash_hisrtory” to view your startup file. Note that each shell has a different startup file, and since we’re using the BASH (Bourne-Again Shell), the startup file is .bash_history. (if you can’t find this file think about one way to display!)
4. Enter the “exit” command to close the terminal window.
5. Enter the command “who” to display all users currently logged onto the system.
6. Enter the commands “whoami” and “who am i” to display your own user information. Note the difference.

Whoami shows my username

7. Enter the “finger” command with your login name to display detailed information about your terminal. (note: if you can’t find finger command, ask your instructor to install it)
8. Change to the “/bin” directory.
9. Display all files (ls –l) from the “/bin” directory.
10. Change to your HOME directory.
11. Use the “cat” command to create a sample text file called “textfile1”. Enter several lines of text of your choice into that file. The output redirection “>” should be used with the cat command “cat > textfile1”.
12. Use the “cat” command to view the file you have just created. Then, use the “wc” command to display statistics information about that file (number of lines, words, and characters).
13. The output redirection can be used with any command. Try the following command which prints all the files in the “/bin” directory into the file output:
14. ls –la /bin > output

15. Use the “cat” command to view the contents of the “output” file. How can you display the contents one page at a time?
16. The output redirection “>” creates a file if it doesn’t exist, and over-writes its contents if the file exists. Try the following command which prints the lists of users into the “output” file we created earlier: who > output
17. Use the “cat” command to display the contents of the “output” file. You’ll notice that the previous contents have been over-written.
18. The output re-direction “>>” can be used to append contents to an existing file. Try this: “date >> output”. You’ll notice that the current date has been appended to the previous contents of the output file.
19. The “touch” command can be used to create an empty file. Try this: “touch myfile”. Check to make sure the file “myfile” has been created.
20. Try the “touch” command on an existing file “touch textfile1” or “touch output”. What is the effect?
21. Create a new file called “memo.txt” with the following information “Hello there, my name is …yourname….”.
22. Append the current date to the end of file “memo.txt”.
23. Invoke the calendar command and redirect its output to the file “memo.txt”.
24. Write a command to display statistics (lines, words, characters) about “memo.txt”.

Minor Cineplex

The Minor Cineplex is a local cinema in Neverland that has operated since 1989. It started off with only 1 theatre. Since then, the business has expanded and there are now 4 theatres. Minor Cineplex shows the same movie in every theatre. There are 20 seats in each row in all theatres.

Theatre 1, 2 and 3 have the same seating arrangements and ticket pricing scheme. Each theatre has 200 seats (i.e., 10 rows) divided equally in 2 sections: Front and Back. The ticket price is 250 Baht for the front section and 350 Baht for the back section.

Theatre 4 has only 100 premium seats in 5 rows. Ticket price is 500 Baht for all seats in row 1 to 4. The ticket price in row 5 is 700 Baht.

We are building a ticket selling system for Minor Cineplex. Note that we will only focus on building data models for each theatre and calculate the amount of tickets sold. You can assume that Minor Cineplex only sells tickets for the upcoming showtime (i.e., no advanced booking is allowed).

Design a system for Minor Cineplex so that it allows the box office staff to view and edit the movie title currently in theatres. It must allow the staff book a seat in the specified theatre (if available). The staff must be able to view the amount of tickets sold in the specified theatre as well as the total amount of tickets sold in all theatres.

Here are some design considerations:

• How many classes do you need for this system?
• What are they representing?
• What would be members in each class?
  • What are the necessary fields and their data types?
  • What are methods?
• What are the relationships between each class?

Your program should provide the following menu.

1. Book a seat
2. Edit movie title
3. View sales report
4. Exit the program

Book a seat: The staff has to enter the theatre number along with the seat information to be booked (which includes the row and the seat numbers). The staff can only book one seat at a time. A confirmation message must be shown, if the booking is successful. A staff should be notified with a different message, if the seat is already taken.

Edit movie title: Minor Cineplex’s current policy is to show the same movie in all of its theatres. Note that this policy may be changed in the future.

View sales report: The sales report must show the movie title, the number of tickets sold and the sales amount (THB) for each theatre. The report must also show the total number of tickets sold and the sales amount (THB) in all theatres.

YOUR PROGRAM SHOULD BE IMPLEMENTED USING JAVA PROGRAMMING!!

Dear Colleague,

Earlier today I built my seventh website using HTML5, CSS3, and Bootstrap4. Bootstrap seems amazing, but it never did what it should do – make my website look better. Also, my page should have a blue theme that was provided in the CSS folder. This also didn’t work.

My website is supposed to look like what is shown in Figure 1 (see below). Someone told me that there are exactly 10 errors on index.html, 10 errors on contact.html, and 10 errors on events.html. Yes, 30 errors total! Can you help me find all of the errors?

Hint: You should not add ANY LINES to the code. There will never be more than one error per line number.
