Select either OSSTMM, PTES, or ATT&CK and explain the importance of using a formal testing methodology. Clearly define what occurs in each phase of your selection and the significance of each phase.

C++ code

a program should prompt the user for the name of the output file. The file should be opened for write operations. Values calculated by the program will be written to this file. The program must verify that the file opened correctly. If the file did not open, an error message should be printed and the user should be prompted again. This should continue until the user supplies a valid filename.

In this Pluralsight Lab, you will continue viewing the course C++ Fundamentals Including C++ 17 by Kate Gregory. Note that in this lab, some concepts are covered that we will cover in class later in the course. However, Having a introduction to these concepts will definitely aid in your understanding later in the course. Also, the application created in this lab will be used in subsequent Pluralsight labs.

Instructions

Begin this lab by viewing the following modules in the Pluralsight course:

• Module 5 (Language Basics - User Defined Types)
• Module 6 (Language Basics - Flow of Control)

Then complete the following tasks:

• Use the Class Wizard in Visual Studio to create a class called Student. (Note that the Class Wizard will automatically create the .h and .cpp files.)
• Your Student class should have the following class members/properties: studentID, firstName, lastName, and studentStatus. (Note that the studentStatus member will be of type Status, which is an enum you will create.)
• Create a default and constructor and a constructor that requires only the Student Id, first name, and last name. (The studentStatus member should not be initialized at this time.)
• Create a member function called getStudentInfo() that returns a string that contains the students first name, last name, and their status.
• Create a destructor for the Student class. (Note that the Class Wizard automatically includes a destructor.)
• Add a status.h file to the solution. Then add a Status enumeration to that file with the following entries: Attending, NonAttending, and Graduated. Then include this file in your class file.
• Add #pragma once to all of your header files
• Write a simple program that asks the user for the Student Id, first name, and last name of the student. Then instantiates a new student object with this information.
• Ask the user if the student is presently attending the school. If the user states "no", ask if a degree was obtain. Use the ternary operator to set studentStatus member of the object to either NonAttending or Graduated based on whether a degree was obtained.
• If the user states that the student is attending, set the studentStatus to Attending.
• Display the student's information by calling the getStudentInfo() member function.

DATA STRUCTURE C++ LANGUGAE

Create a notepad that allows the user to write text (char by char) on the console. For this
purpose, the user should be able to control and track the movement of the cursor. The user
should be able to navigate to any part of console (cursor control) in order to perform any
insertion or deletion of words.
Internally, the notepad is composed of two-dimensional linked list (every node should
comprise of data element (char) and 4 pointers for navigating left, right, up, and down). Since
text can be written on multiple lines, each row of the 2D linked list represents one line. Each
line is terminated when a newline is inserted in the ADT.

Systems Analysis and Design

Create a Context Diagram for a purchasing system.

Create this first level of a DFD for this system.

Help is much appreciated. Thank you..

Write a method with the following header to return an array of integer values which are the largest values from each row of a 2D array of integer values

public static int[] largestValues(int[][] num)

For example, if the 2D array passed to the method is:

8 5 5 6 6
3 6 5 4 5
2 5 4 5 2
8 8 5 1 6

The method returns an array of integers which are the largest values from each row as follows:

8
6
5
8

In the main method, create a 2D array of integer values with the array size 4 by 5 and invoke the method to find and display the largest values from each row of the 2D array.

You can generate the values of the 2D array using the Math.random() method with the range from 0 to 9.

JAVA programming

A zoo is developing an educational safari game with various animals. You will write classes representing Elephants, Camels, and Moose.

Part A: Think through common characteristics of animals, and write a class ZooAnimal.

☑ ZooAnimal should have at least two instance variables of different types (protected), representing characteristics that all animals have values for.

☑ It should also have at least two methods for behaviors that all animals do; these can simply print out a String stating what the animal is doing. (accessors and mutators are not behaviors). Include at least one parameterized constructor.

Part B ☑ Create classes Elephant, Camel, and Moose, all of which extend ZooAnimal. In each, include a default constructor that calls the parameterized superclass constructor.

☑ To one class (of Elephant, Camel, and Moose), add another instance variable specific to that type of animal. To another, add another behavior method. In a third, override a behavior from ZooAnimal.

Part C ☑ Create a test harness for the animal classes. In a main create at least one Elephant, Camel, and Moose, and show which behavior methods are usable for each.

☑ [EC+10] Create another animal class inheriting from one of your three types (doesn't have to be zoologically accurate, but should make some sense), and either add an instance variable or add or override a method. This class should also be tested in the harness.

What is a geographic information system (GIS)? What purpose does it server? Name the two major elements that are combined to make up a GIS.

Download the world.SQL and run it in MySQL. Now based on this database, write query that shows a) the most populated city in each country. b) the second most populated city in each country. c) the most populated city in each continent. d) the most populated country in each continent. e) the most populated continent. f) the number of people speaking each language. g) the most spoken language in each continent. h) number of languages that they are official language of at least one country. i) the most spoken official language based on each continent. (the language that has the highest number of people talking as their mother tongue) j) the country with the most (number of) unofficial languages based on each continent. (no matter how many people talking that language) k) the countries that their capital is not the most populated city in the country. l) the countries with population smaller than Russia but bigger than Denmark.

Describe how five career areas can benefit from computer systems..

Need the following program in Python:

Create a program that calculates the estimated duration of a trip in hours and minutes. This should include an estimated date/time of departure and an estimated date/time of arrival.

Specifications

• For the date/time of departure and arrival, the program should use the YYYY-MM- DD format for dates and the HH:MM AM/PM format for times.
• Create a single data/time string variable based on the two input variables. Use this combined string variable to create a departure date-time object that will be used to determine the estimated arrival date and time.
• For the miles and miles per hour, the program should only accept integer entries like 200 and 65.
• Calculate the hours travelled based on the integer division of miles divided by mph. The minutes are based on the remainder of miles divided by mph. The remainder must then be converted to minutes based on the mph.
• Assume that the user will enter valid data.

Extra credit This is the formula for the future worth of an investment over time with consistent additional monthly payments and a steady rate of return. This can give you a bonus of 200 points. You will not be penalized if you do not do this nor will you be penalized if it is incorrect. This is a challenging problem because of all the mathematics involved. Let’s see how good you really are. FV = PV (1+ r/k) nk +PMT * [ (1+r/k) nk −1] * (1+ r/k) r/k FV : future value PV : initial value R : interest rate K : regular periodic investments • Annually, • Semi-annually, • Quarterly, • Monthly PMT: payment (installments) N : years Problem: You wish to start putting money away for your retirement (far-fetched, huh) anyway, how much would you have after 45 years if you started with an initial payment (PV) of $1000.00 and invested $250 (K) monthly. The dividend payments are 6% (R)and you invest $250 a month for the next 45 years. Your investment has an annual rate of return (R) of 6%.

Show how you would break this problem down into pieces (your pseudo code).

Then show your source code and display your initial investment, rate of return, length of time, monthly payments into the account and the final outcome. Show how much money you invested and what the final amount is, you’ll be surprised. HINT: try doing this problem manually first
