C++ Lexicographical Sorting

Given a file of unsorted words with mixed case: read the entries in the file and sort those words lexicographically. The program should then prompt the user for an index, and display the word at that index. Since you must store the entire list in an array, you will need to know the length. The "List of 1000 Mixed Case Words" contains 1000 words.

You are guaranteed that the words in the array are unique, so you don't have to worry about the order of, say, "bat" and "Bat."

For example, if the array contains ten words and the contents are

cat Rat bat Mat SAT Vat Hat pat TAT eat

after sorting, the word at index 6 is Rat

You are encouraged to use this data to test your program.

Write ArraysDriver (similar design to LoopsDriver):

• Write an infinite loop which does the following
  • Prints a menu of 11 options (0 to exit)
  • Asks the user which method to call
  • Calls the method and prints out the answer

In this assignment, you will pass arrays as arguments to these methods. You may declare and initialize these arrays before the loop and reuse them throughout your application. For this assignment, use arrays of 5 elements. You will need 2 int[] arrays and 2 String[] arrays to be declared and initialized before the main loop. You may use arbitrary values for each item/element in the arrays.

The only input you will need from the user (other than the menu option selected) is a word to use for arrayContainsWord and getIndexOfWord.

1. Read previously created binary file using ObjectInputStream
2. Create an appropriate instance of HashMap from Java library
3. Populate the HashMap with data from binary file
4. Display the information read in a user friendly format

Problem:

Given: Words.dat – a binary file consisting of all the words in War and Peace

Goal: Read the words in from the binary file and figure out how many times each word appears in the file. Display the results to the user.

Use a HashMap with the word as a key (String) and an Integer as the value.   For each word, first check to see if it already exists in the Map. If not, add the word as key with a value of 1 for the Integer value.

If it does, get the current value and increment by 1 – replace the old key,value with the new key, value.

After all the words are processed and the HashMap is complete. Iterate through the Hash map and display the results in a user -friendly fashion. Tell me which option you chose in the Assignment box when you submit the homework

Display Options: (Choose one not all)

1. Create an easy to read table and print to the console. Hint: Use tabs (/t) (values are not from file)

Example:

Word                     Count

A                             190

Apple                    6

Etc

2. Display on a Java FX Gui – use ListView for the Words and click to see count

C. Create a text file with the data formatted similar to the console

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
import java.util.ArrayList;
import java.util.HashSet;

Part 3

Imagine that the economy is experiencing inflation and that the Reserve Bank of Australia (RBA) decides to implement a contractionary monetary policy or 'tight money' to return inflation to its target level.

a) What type of open market operations (OMOs) will the RBA undertake consistent with a contractionary monetary policy approach?

b) How will the money supply be affected?

c) Explain how the three stages of transmission process from a contractionary monetary policy link a change in interest rates with a change in an economy’s equilbrium level of output.

d) Using the IS-LM curve diagram, illustrate the impact of a contractionary monetary policy. Make sure to clearly indicate the new equilibrium position including the interest rate and output level.

At the end of your answer to Part 3 state the word count for sub-part c. Your answer to Part 3 sub part c should not exceed 100 words. (Note: answers to sub-parts a and b while written should be no longer than 1 sentence each and hence are excluded from the word count requirement).

(0.5 marks for sub-parts a and b, 3 marks for sub-part c, 2 marks for sub-part d plus 0.25 marks for satisfying the word count requirements - Part 3 worth 6.25 marks)  

Question 7

The profit figure is an objective measure with some subjective estimates. It has been argued that it does not reflect current value. For example in a period of high inflation, Casi Plc decided to use replacement cost accounting. Closing inventory was purchased for £35 per unit. The general price increases during the period meant the purchase price had increased by 30% by the end of the period.

The Finance manager of Casi Plc is interested in how Positive accounting, Normative accounting, Public interest and Capture theories impact on the accounting theory.

Caspi Plc has implemented IAS 36 impairment of assets. All the assets were reviewed for impairment where appropriate and the impairment loss has been included within the financial statements.

Requirement:

1. Explain any two criticisms of the accountant’s measure of profit. (maximum word count 60)

2. What is the value per unit of closing inventory of Casi Plc at the end of the period?

        iii)        Explain the following in relation to accounting theory.       

• Positive accounting theories
• Normative accounting theories
• Public interest theory
• Capture theory

(maximum word count 160)                     

iv) Describe what is meant by ‘impairment’ and briefly explain the procedures that must be followed when performing an impairment review. (maximum word count 220)

in assemby, please share code and output - thanks

1. First clear all your general purpose registers by moving the value “0” into them. Initialize a variable for a BYTE, WORD, DWORD storage size each with any desired value in the data segment. Initialize another variable called Result with the size of a DWORD and make the value as an uninitialized value. In the code segment, create a label called L1 that moves the variables in the appropriate sized register and making sure NOT to overwrite them in the process. After, create another label L2 that adds all these values together and at the end of your program make sure your ECX register contains the final value. Call the DUMPREGS instruction to display your register values and move the final result into the Result variable.

2. Use the following code below as a template and follow the instructions written in the comments ;Assume I have the following data segment written: .data val1 BYTE 10h val2 WORD 8000h val3 DWORD 0FFFFh val4 WORD 7FFFh ;1. Write an instruction that increments val2. ;2. Write an instruction that subtracts val3 from EAX. ;3. Write instructions that subtract val4 from val2. .code ;Write your instructions here
