I need to know how to build a flag in c++ for Italy

Write a program in python that opens a text file, whose name you enter at the keyboard.

•You will be using the file filetext.txt to test your program

•Print out all of the individual, unique words contained in the file, in alphabetical order.

MAKE SURE THAT ALL THE WORDS YOU PRINT OUT ARE IN A SINGLE COLUMN, ONE WORD PER COLUMN!•Print out the number of unique words appearing in text.txt

First level CS, should not be too complex. Need in a week.

You must turn in three java files - FoodItem.java, Order.java and MyOrder.java. In addition to these, you must include a screenshot of the output by executing the file MyOrder.java. Submissions without all these files will not be graded.

Task 1:

Design a class named FoodItem which contains the following fields:

Type of food item: Like entree, bread, soup, salad, drink or dessert to name a few

Item number: could be an alphanumeric code or just a number

Unit price: $xx.xx

You must include appropriate instance methods like constructors, getters , setters and toString for all the fields.

Task 2:

Create another class named Order which has the following fields:

Order number: It could be an alphanumeric id or numeric.

Customer Name: First and last name of the customer

Combo meal option: yes or no

DiscountAmount: If combo meal is chosen, offer a 5% discount

OrderTotal: Total bill amount

You must create the following methods for the Order class:

Constructor (s) - You may include an extra constructor that takes in the Customer name as a parameter.

Setters, getters and toString methods for the appropriate fields.

add(item,quantity) - this method adds the price of purchasing an item to the Order total.

getOrderTotal() - this method returns the total bill amount to be paid by the customer after including any discounts applicable and also a 10% sales tax on the total amount.

Task 3:

Create a class named MyOrder that displays a Menu of items available to choose from, creates an order for two different customers and reports their total bill amount. Use appropriate print statements to guide the user through the ordering process. Remember, this is the class where you are actually placing an order (action required). So, this class must contain the main method.

1. Assume that the cache size is 256kB, and each cache line is 64 Bytes. (10%)

1. Let us assume this is a Two-way associative cache. How many cache sets are there?

2. Let us assume the following memory blocks need to be accessed:

Memory Blocks #4100, 8196, 2052, 8196, 2052, 4100

If the cache is initially empty, what is the cache hit/miss rate?

Social Security Payout. If you’re taking this course, chances are that you’re going to make a pretty good salary – especially 3 to 5 years after you graduate. When you look at your paycheck, one of the taxes you pay is called Social Security. In simplest terms, it’s a way to pay into a system and receive money back when you retire (and the longer you work and the higher your salary, the higher your monthly benefit). Interestingly, your employer will pay the same amount for you. The current tax rate is 6.2% until you make approximately $132,900. For this assignment, we’re going to help out hourly employees. Design (pseudocode) and implement (source code) a program that asks users how much they make per hour, the number of hours they work per week, and calculates the yearly income. For the second half, the program should calculate and display the amount of Social Security tax the user will pay for that year. You must write and use at least two functions in addition to the main function. At least one function must not have a void return type. Note, don’t forget to put the keywords “public” and “static” in front of your functions. Document your code and properly label the input prompt and the outputs as shown below.

Sample run 1: Enter hourly wage: 10

Enter your hours per week: 40

You will earn $20800.0 per year

You will pay $1289.6 in Social Security tax

Sample run 2: Enter hourly wage: 40

Enter your hours per week: 60

You will earn $124800.0 per year

You will pay $7737.6 in Social Security tax

In the game of Lucky Sevens, the player rolls a pair of dice. If the dots add up to 7, the player wins $4; otherwise, the player loses $1. Suppose that, to entice the gullible, a casino tells players that there are many ways to win: (1, 6), (2, 5), and soon. A little mathematical analysis reveals that there are not enough ways to win to make the game worthwhile; however, because many people's eyes glaze over at the first mention of mathematics “wins $4”.

      Your challenge is to write a program that demonstrates the futility of playing the game. Your Python program should take as input the amount of money that the player wants to put into the pot, and play the game until the pot is empty.

            The program should have at least TWO functions (Input validation and Sum of the dots of user’s two dice). Like the program 1, your code should be user-friendly and able to handle all possible user input. The game should be able to allow a user to ply as many times as she/he wants.

            The program should print a table as following:

      Number of rolls             Win or Loss                Current value of the pot

                              1                                 Put                                   $10

                    2                                           Win                                  $14

                    3                                           Loss                                 $11

                              4

                              ##                              Loss                                 $0

        You lost your money after ## rolls of play.

        The maximum amount of money in the pot during the playing is $##.

        Do you want to play again?

      At that point the player’s pot is empty (the Current value of the pot is zero), the program should display the number of rolls it took to break the player, as well as maximum amount of money in the pot during the playing.

        Again, add good comments to your program.

        Test your program with $5, $10 and $20.

Write a C++ program that reads daily weather observation data from a file and writes monthly and annual summaries of the daily data to a file.

a. The daily weather data will be contained in a file named wx_data.txt, with each line of the file representing the weather data for a single day.

b. For each day, the date, precipitation amount, maximum temperature, and minimum temperature will be provided as tab-separated data with the following format: 20180101 0.02 37 23 20180102 0.00 42 18 <...data for the remainder of the year here...>

c. For the first entry in the daily data above, the date is 20180101 (1 January 2018), the precipitation amount is 0.02 inches, the maximum temperature is 37°F, and the minimum temperature is 23°F.

d. You may assume that the weather data is complete (i.e., there is data for each day of every month of the year) and that the data contains no errors.

2. The program must read from file each daily weather observation and write a summary by month and year to a file named wx_summary.txt.

a. The output that is written to file must have the following format:

java - Write a method that sums all the numbers in the major diagonal in an n x n matrix of double  values using the following header:

public static  double sumMajorDiagonal(double [][] m)

Write a test program that first prompts the user to enter the dimension n of an n x n matrix, then asks them to enter the matrix row by row (with the elements separated by spaces). The program should then print out the sum of the major diagonal of the matrix.

SAMPLE RUN:

Enter dimension n of nxn matrix:Enter row·0:Enter row 1:Enter·row 2:Enter row 3:17.1

(can have 3 or 4 rows)

Problem 3: The IsSorted class [30’]

Description:

This Java program will create an integer array object with arbitrary elements, and judge whether this array is sorted (non-decreasing). For example, array1 {2,3,1,0} is not sorted, while array2 {5, 8,10,12,15} is sorted.

You may assume the array is non-empty.

Specifications:

In addition to the main method, you need to create another method

• isSorted()

main Method

1. The main method will create an array of integers, and initialize its elements with arbitrary values.
2. The main method will then call the isSorted() method by passing this array. The isSorted() method will judge whether the array is sorted or not and return true or false.
3. Based upon the results of the isSorted() method, the main method will print out a corresponding message.

isSorted Method

The isSorted() method takes in an array of integers as a parameter. It checks whether all elements in this array are sorted (arranged in non- decreasing order) or not, and return true or false.

Output

Your output should look something like follows:

//Suppose the array is [5, 0, 2, 3, 8]

$java IsSorted

The array is not sorted.

//Suppose the array is [1, 1]

$java IsSorted

The array is sorted.

//Suppose the array is [2, 6, 10, 15, 20]

$java IsSorted

The array is sorted.

//Suppose the array is [7, 4, 3, 0]

$java IsSorted

The array is not sorted.
