Book-O-Rama Catalog Search

    Choose Search Type:

         Author      Title      ISBN    

    Enter Search Term:

-------------------------------------------------------------------------------------

Then save above document to the local directory (C:\temp) and make sure that you saved it in the plain text format (in the “Save as type” popup window, choose “Text Document (*.txt)), name your file “firstpage.txt”.

Step 3: test your web page

You can test your page by doing the following:

1. change the file extension to html. Thus, you should have a file firstpage.html.

2. create a sub director named “firstwebsite” in the web server’s root directory. Your web root may be different from mine. In my machine, the XAMPP is installed at C drive. Thus, the web root will be:

C:\xampp\htdocs\

At the end of this step, the directory structure will be:

C:\xampp\hpdocs\firstwebsite\

3. copy the newly created file “firstpage.html” to the directory shown in the previous line.

4. fire up a web browser and type the following to the URL:

http:\\localhost\firstwebsite\firstpage.html

Provide a detailed code for Double Encryption using Image Steganography in PYTHON

First encrypt the data(using RC4/AES algorithm) before storing it in the image, after encrypted data is stored in the image, use image steganography to encrypt the image. Hence, we are using double encryption

Write a C++ program that requires the user to type in an integer M and computes the function y(M) which is defined by y(0)=2, y(1)=1, y(m+1)=y(m)+2*y(m-1).

The section on hacking by governments (Section 5.3.4) describes, mostly, incidents of hacking for military or strategic purposes.

1. Find and summarize information about hacking for industrial or economic espionage.

Consider the following class definition:

                  public class Parent {

              private int varA;

              protected double varB;

              public Parent(int a, double b){

varA = a;

varB = b;

              }

              public int sum( ){

                   return varA + varB;

              }

public String toString( ){

                   return "" + varA + "   " + varB;

              }

        }

Consider that you want to extend Parent to Child. Child will have a third int instance data varC.

1. Write the parameterized constructor definition for Child;
2. Write the code to override the sum() method to now add all three values and return the sum;
3. Write the code to define a method average() to calculate and return the average of varB and varC.
4. Write the code to override the toString() method for Child.

Using the class definitions for Parent and Child from Question 2, write a Java application that will represent a family of 4 members.

1. Declare a Parent array of size 4 called family.
2. Instantiate two objects of type Parent using the parameterized constructor and assign each to the first two elements of family. Use values retrieved from the user as the parameter values.
3. Instantiate two objects of type Child using the parameterized constructor and assign each to the last two elements of family. Use values retrieved from the user as the parameter values.
4. Invoke the average() method for the two Child objects and display the result.
5. Write a loop to display the member values of each object in family using the toString() method.

Activity Statement-  The Payroll department at xyz company would like you to develop a computer program that will determine the net pay of an employee. Design a Python program, which utilizes modules, that asks the user to enter the Name of employee, the total number of hours worked by the employee, and the hourly pay rate of the employee. The program will determine the Employee Gross Pay, the Paid Federal Taxes ( 30% of the Employee Gross Pay ), the Paid State Taxes ( 10% of the Employee Gross Pay ), and the Employee Net Pay ( Gross Pay - Federal Taxes - State Taxes ). In addition, the program will display the following items:

• Employee Name
• Employee Total Hours Worked
• Employee Hourly Pay Rate
• Employee Paid Federal Taxes
• Employee Paid State Taxes
• Employee Net Pay

Activity Instructions-

1. You have only one attempt to submit. Therefore, be sure that you are submitting and uploading the correct solution. If you submit the wrong version, you will not be allowed to resubmit the solution. It is your responsibility to ensure that you did upload the correct solution!
2. Launch the Python IDLE program.
3. Develop the Python program using the following criteria:-
   1. The program consists of seven modules namely, main( ), getEmpInfo( ), computeGrossPay( ), computePaidFedTax( ), computePaidStateTax( ), computeNetPay( ), and printEmpInfo( )
   2. The main( ) module will call the rest of the modules.
   3. The purpose of the getEmpInfo( ) module is to allow the user to enter the employee name, the employee total working hours, and the employee hourly pay rate. The module getEmpInfo( ) is called by the main( ) module.
   4. The purpose of the computeGrossPay( ) module is to compute the employee gross pay. Use the formula Employee Gross Pay = Hours Worked times Hourly pay rate. Please discard any overtime. The computeGrossPay( ) module is called by the main( ) module.
   5. The purpose of the computePaidFedTax( ) module is to compute the amount of money which the employee should pay as a federal tax. Use the formula Employee Paid Federal Taxes = 30% of the Employee Gross Pay. The computePaidFedTax( ) module is called by the main( ) module.
   6. The purpose of the computePaidStateTax( ) module is to compute the amount of money which the employee should pay as a state tax. Use the formula Employee Paid State Taxes = 10% of the employee Gross Pay. The computePaidStateTax( ) module is called by the main( ) module.
   7. The purpose of the computeNetPay( ) module is to compute the employee net pay. Use the formula Employee Net Pay = Employee Gross pay - ( Paid Federal Tax + Paid State Tax ). The computeNetPay( ) module is called by the main( ) module.
   8. The printEmpInfo( ) module is called by the main( ) module. This module should display the following items:
      • Employee Name
      • Employee Total Working Hours
      • Employee Hourly Pay
      • Employee Paid Federal Taxes
      • Employee Paid State Taxes
      • Employee Net Pay

                   // Create a regex pattern
                    Pattern pt = Pattern.compile(regex);
                  
                    System.out.println("Enter a input string to search: ");
                    String sr = input.nextLine();
                  
                    // Create a Matcher object
                    Matcher mt = pt.matcher(sr);

                    boolean found = false;
                    while (mt.find()) {
                        System.out.printf("I found the text \"%s\" starting at " +
                                          "index %d and ending at index %d.\n",
                                          mt.group(), mt.start(), mt.end());
                      
                        found = true;
                    }
                  
                    if(!found){
                        System.out.println("No match found.");
                    }
                }
       }
