1. Copy the files from Assignment 1 to Assignment 2. Relabel as necessary

2. Create 3 instances of the PetFoodCompany class - dogFoodMaker, catFoodMaker, fishFoodMaker.

3. Internally set the division name for each instance. (I.E. "Alpo" for dogFoorMaker, "Purina" for CatFoodMaker, "GloFish" for fishFoodMater)

4. Prompt me to enter the Company Name and Quarter only once.

5. For each of the above instances, prompt me for total sales and total expenses. A loop is not expected.

6. For each instance of the class, display the Company Name, Quarter. Division Name, Total Sales, Total Expenses and Net Income. The company name and quarter should be displayed for all instances.

5 Points Extra Credit: Create a method in the PetFoodCompany class that will do step 6 and call it from main() for the 3 instances.

Here is the code:

PetFoodComp.h:

class PetFoodCompany
{
public:
  
PetFoodCompany();

char getQuart();
char* getCompany();
char* getDivision();

void setQuart(char quart);
void setTotalSales(float totalSales1);
void setTotalExpences(float totalExpences1);
void setCompany(char name[]);
void setDivision(char name1[]);


float getTotalSales();
float getTotalExpences();

double netIncome();
  

private:
  
char company[40];
char division[40];

static char quart;
static double BonusRate;

float totalSales;
float totalExpences;
  
  
};

PetFood.cpp:

#include <iostream>
#include <cstring>
#include "PetFoodComp.h"

using namespace std;


double PetFoodCompany::BonusRate = 0.02;
char PetFoodCompany::quart = '1';

PetFoodCompany::PetFoodCompany()
{
   strcpy(company, "myCompanyName");
}

char PetFoodCompany::getQuart()
{
   return quart;
}

float PetFoodCompany::getTotalSales()
{
   return totalSales;
}

float PetFoodCompany::getTotalExpences()
{
   return totalExpences;
}

char* PetFoodCompany::getCompany()
{
   return company;
}

char* PetFoodCompany::getDivision()
{
   return division;
}

void PetFoodCompany::setQuart(char quart1)
{
   if (quart1 == '1' || quart1 == '2' || quart1 == '3' || quart1 == '4')
       quart = quart1;
}

void PetFoodCompany::setTotalSales(float totalSales1)
{
   totalSales = totalSales1;
}

void PetFoodCompany::setTotalExpences(float totalExpences1)
{
   totalExpences = totalExpences1;
}

void PetFoodCompany::setCompany(char name[])
{
   strcpy(company, name);
}

void PetFoodCompany::setDivision(char dname[])
{
   strcpy(division, dname);
}

double PetFoodCompany::netIncome()
{
   return (totalSales - totalExpences);
}

PetFoodMain.cpp:

#include <iostream>
#include <cstring>
#include "PetFoodComp.h"


using namespace std;

int main()
{
   double totalSales, totalExpences;
   PetFoodCompany pet;
   cout << "Company Name is " << pet.getCompany() << "\n";
   cout << "Current Quarter is " << pet.getQuart() << "\n";


   cout << "Enter Total Sales: ";
   cin >> totalSales;

   cout << "Enter Total Expences: ";
   cin >> totalExpences;

   pet.setTotalExpences(totalExpences);
   pet.setTotalSales(totalSales);

   cout << "Net Income: " << pet.netIncome() << "\n";

   return 0;
}

write a program in Java that can take a given text file and then compress it with Huffman coding due 20 october 2020

Huffman coding can be used to “zip” a text file to save space. You are required to write a program in Java that can take a given text file and then compress it with Huffman coding. Your program should be able to decompress the zipped files as well [4 marks]. In addition, show percentage gain in data compression i.e., how much space is saved [2 marks].

Compare the effectiveness of your Huffman code with 7-zip and WinZip softwares. You will get a bonus mark if you enhance the existing Huffman code somehow to have a better file compressor. It can also be published as a research article.

Correct Implementation: read about FileOutputStream, FileInputStream, FileReader etc to read/write to a binary file. You may use Integer.parseInt(huffmanCodeAsString,2) to store encoded Huffman code into a binary file. Huffman encoding should convert a text file to a binary file then decoding should convert the binary file back to a text file.

Please provide all java code. Be clear as possible when you paste the code so that it works in my pc  

Use netbeans IDE.

PROGRAMING in C RPSLS: The program that we must implement must allow two players to play...

PROGRAMING in C RPSLS:

The program that we must implement must allow two players to play in the same console (there will be only one program)
The program will initialize the information necessary to be able to store the name of two players and their respective markers throughout the game, to present
a result message at the end of the game.

1. When the program is ready for the game to start, it will ask PLAYER1 enter your name.
2. It will then ask PLAYER2 to enter their name.

As long as the game is not over (that is, until one of the two players arrives to 3 points) the program:
• Will ask PLAYER1 to place his bet (can be entered in the form of numeric code, or in the form of a character string)
• Will ask PLAYER2 to place his bet (similarly)
• Evaluate both bets, and modify the markers of each of the two players based on bets
• When either of the two players reaches the score of 3 points, it will be over the game

3. Message will be displayed on the screen that says: "PLAYER NAME1 has won PLAYERNAME2: SCOREBOARD "if PLAYER1 has won, where SCORE will be the result of the game (for example 3-2).

Then it will say "PLAYERNAME2 has lost against PLAYER NAME1: MARKER "because then PLAYER2 will have lost, and MARKER will have the result reversed (for example 2-3). If he player who has won is PLAYER2, the messages will indicate the victory of the PLAYER2 and PLAYER1's defeat.

As soon as the above message is presented, the program will end the program must NOT have any input parameters at the time of making
the program call, and all the parameters you might need (names and bets) will be entered by keyboard (upon presentation of a message that clearly state what the user is expected to key in (such as,say your NAME, enter your BET, etc.)

Q4. Assume you have been given a scrambled text file with some hidden text data similar to the one in your assessment. What will be the best method that you will use to unscramble the file and why would you choose this method? Justify your answer. [5 marks] You have collected a digital evidence from a crime scene and calculated its hash value using WinHex editor with MD5 algorithm. You have stored the evidence in a forensics lab. After a week, when you started analysing the evidence, you again calculated the hash value of the evidence using Autopsy and with SHA-1 algorithm. You found that the hash value of the evidence is now changed. Describe why the hash value now is different than the one you calculated when you acquired the evidence? [5 marks]

You have a program which has an interface for a remote

public interface Remote {
public void on();
public void off();
public void setChannel(int channel);
public int getChannel();
public void sleep(int numMinutes);
}

You've been working with a Spanish firm that wants to use your program, but they have a different interface

public interface controlRemoto {
public void enciende();
public void apague();
public void cambiaCanal(int channel);
public int qualCanal();
public void duerme(int numMinutes);
}

Create an adapter/wrapper around controlRemoto to make it look like Remote. For simplicity, the methods in both interfaces are in the correct order.

ALGORITHM MatrixMultiplication(A[1..n, 1..n], B[1..n, 1..n])
// Multiply two square matrices of order n using the definition-based algorithm //Input: twon×nmatricesAandB
// Output: matrix C = AB
fori←1tondo

for j ← 1 to n do C[i, j] ← 0

for k ← 1 to n do

C[i, j] ← C[i, j] + (A[i, k] * B[k, j]) return C

The basic operations are the addition and multiplication of matrix elements at line 9. Determine the number of basic operations performed for two input matrices of size n × n. Write your answer in simplest form, if possible.
