An automatic ticket issuing system sells rail ticket. User select their destination and input a credit card and a personal identification number. The rail ticket is issued and their credit account charged. When the user presses the start button, a menu display of potential destinations is activated, along with a message to the user to select a destination. Once a destination has been selected, users are requested to input their card. Its validity is checked and user is then requested to input a personal identifier. When the credit transaction has been validated, the ticket is issued
functional requirement defines a system or its component whereas a non-functional requirement defines the performance attribute of a software system. ... Types of Non-functional requirement are Scalability Capacity, Availability, Reliability, Recoverability, Data Integrity, etc

Write a program that randomly (using the random number generator) picks gift card winners from a list of customers (every customer has a numeric ID) who completed a survey. After the winning numbers are picked, customers can check if they are one of the gift card winners. In your main function, declare an integer array of size 10 to hold the winning customer IDs (10 winners are picked). Pass the array or other variables as needed to the functions you write. For each step below, decide what arguments need to be passed to the function. Then add a function prototype before the main function, a function call in the main function and the function definition after the main function.
Answer:
Explanation:
Since no customer ID information was provided, after a quick online search I found a similar problem which indicates that the ID's are three digit numbers between 100 and 999. Therefore, the Java code I created randomly selects 10 three digit numbers IDs and places them in an array of winners which is later printed to the screen. I have created an interface, main method call, and method definition as requested. The picture attached below shows the output.
import java.util.Random;
interface generateWinner {
public int[] winners();
}
class Brainly implements generateWinner{
public static void main(String[] args) {
Brainly brainly = new Brainly();
int[] winners = brainly.winners();
System.out.print("Winners: ");
for (int x:winners) {
System.out.print(x + ", ");
}
}
public int[] winners() {
Random ran = new Random();
int[] arr = new int[10];
for (int x = 0; x < arr.length; x++) {
arr[x] = ran.nextInt(899) + 100;
}
return arr;
}
}

Your systems analysis team is close to completing a system for Azuka Theatre. Kevin is quite con- fident that the programs he has written for Azuka's inventory system used for keeping track of stage scenery and props will perform as required because they are similar to programs he has done before. Your team has been very busy and would ideally like to begin full systems testing as soon as possible. Mark and Allison, two of your junior team members have proposed the following:
a. Skip desk checking of the programs (because similar programs were checked in other installa- tions; Kevin has agreed).
b. Do link testing with large amounts of data to prove that the system will work.
c. Do full systems testing with large amounts of live data to show that the system is working. Respond to each of the three steps in their proposed test schedule. Use a paragraph to explain your response.
Answer:

Explanation:

Desk checking is a method to check the logic of an algorithm by manually working through it. There are many reasons for Desk Checking that may be omitted or simplified.
What are the reasons for desk checking?If the current program’s logic is identical, then this step may be omitted; this, however, implies some effort to verify “sameness.” If truly identical, perhaps there is re-usable code, or the code to be developed should become a reusable library routine.
Link testing is the testing of the group of modules in order to ensure that the modules operate correctly in combination. It generally verifies that the function or operation is executed properly. System testing is a type of testing that is used to confirm the actual function of the system in which a work is executed or performed.
Therefore, all of the testing mechanisms are well described above.

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. g
Answer:
The program in Python is as follows:
string = input("String: ")
chr = input("Character: ")[0]
total_count = string.count(chr)
print(total_count,end=" ")
if total_count > 1:
print(chr+"'s")
else:
print(chr)
Explanation:
This gets the string from the user
string = input("String: ")
This gets the character from the user
chr = input("Character: ")[0]
This counts the occurrence of the character in the string
total_count = string.count(chr)
This prints the total count of characters
print(total_count,end=" ")
If the count is greater than 1
if total_count > 1:
Then it prints a plural form
print(chr+"'s")
If otherwise
else:
Then it prints a singular form
print(chr)

Economic Batch Quantity depends on
دی ماه
Material, labour
Set-up costs, carrying
Transportation, carrying
Warehousing, labour
Answer: Set-up costs, carrying costs
Explanation:
When it comes to production, the goal is to produce with as little costs as possible so that more profit can be made when the goods are sold.
This is why the Economic Batch Quantity is important. It shows the maximum amount of goods that can be produced in a particular production run such that costs will be minimized.
As such, it is based on the set-up costs of production for that run as well as the carrying costs through the run.

You are an IT network administrator at XYZ Limited. Your company has critical applications running of its Ubuntu Linux server. Canonical, the company that owns and maintains Ubuntu just releases an update to patch a security vulnerability in the system.
Required:
What BEST action you should take?
Answer:
Explanation:
I believe that the best course of action would be to divide the companies computers and run the critical applications on half of the systems while the other half update to the latest Ubuntu release. Once that half is done updating, you run the applications on the updated systems and update the other half of the systems. This will allow the company to continue its operations without any downtime, while also updating to the latest Ubuntu release on all systems and making sure that all systems do not have any security vulnerabilities due to outdated software.

Answer:

Explanation:
There used to be a popular type of pulp book for younger readers. They were called "Choose Your Own Adventure" novels. The idea was pretty simple. You'd start reading and then a few pages into the book, there would be a plot development that required a choice. The book might describe that you've entered a spooky house and the door has locked behind you. It would then ask you if you want to try to exit by going through the kitchen or exploring upstairs. If you chose to go into the kitchen, you'd turn to page 200, if you chose to go upstairs, you'd turn to page 43. This would repeat maybe five or six times though the book. You could re-read it a few times and try different outcomes.
In this lab you are going to create a choose your own adventure application using navigation controllers. The introduction screen to your application will contain a few lines of text to set up a story and then leave the user with a choice. Below the text, you will present two buttons that correspond to the different choices.
For example, you might see the following text on the main screen:
You are walking down the street when a tiger runs up and takes your lunch and then runs away...
Do you want to chase the tiger or run away?
Chase
Run Away
The user must then tap one of the buttons. This will move the user to a new screen with a few more lines of the story and another choice and two more buttons. You will create three (3) turning points in your story. This means that your story will have eight (8) different possible outcomes and a total of 15 screens.
Requirements
The story must ask three (3) questions, no matter how the user answers the previous question. All the questions must be different and result in a different story text.
The story must have eight (8) possible different final outcomes.
The story must include a minimum of 15 screens in total.
Create content that is appropriate and not-offensive. We will share these and play them together.
For extra credit you can add an extra screen and use inputs to capture data from the user such as a name, favorite food, or lucky number and use this data in the story.

calculate the total and average number from 1 to 100
Answer:
Thus, 50.5 is an average of numbers from 1 to 100.
Explanation:
getcalc.com's average calculator to find what is the mean or average of natural numbers upto 100.
50.5 is an average of numbers from 1 to 100 mentioned in the below table, by substituting the total sum and count of numbers in the below formula. The corresponding formulas, chart, examples & workout may help students, teachers or professionals to learn, teach or practice the average of natural numbers upto 100.
Address the formula, input parameters & values.
Formula: Average = Total Sum of Numbers / Total Count of Numbers
Input parameters & values:
The numbers from 1 to 100 are
1, 2, 3, 4, . . . . , 98, 99, 100
Total Count of Numbers = 100
step 2 Find the sum of numbers from 1 to 100.
sum = 1 + 2 + 3 + . . . . + 99 + 100
= 5050
step 3 Divide the sum by 100 Average = 5050/100 = 50.5
Thus, 50.5 is an average of numbers from 1 to 100.
Write a program that prints the sum of the even numbers and the products of odd numbers on the screen
Answer:
The program in Python is as follows:
n = int(input("Number of inputs: "))
total = 0; product = 1
for i in range(n):
num = int(input(": "))
if num%2 == 0:
total+=num
else:
product*=num
print("Sum of even: ",total)
print("Product of odd: ",product)
Explanation:
This prompts the user for the number of inputs, n
n = int(input("Number of inputs: "))
This initializes sum (total) to 0 and products to 1
total = 0; product = 1
This iterates through n
for i in range(n):
This gets the inputs
num = int(input(": "))
If input is even, calculate the sum
if num%2 == 0:
total+=num
If otherwise, calculate the product
else:
product*=num
Print the required outputs
print("Sum of even: ",total)
print("Product of odd: ",product)
Create a class named TriviaGameV1 that plays a simple trivia game. The game should have five questions. Each question has a corresponding answer and point value between 1 and 3 based on the difficulty of the question. TriviaGameV1 will use three arrays. An array of type String should be used for the questions. Another array of type String should be used to store the answers. An array of type int should be used for the point values. All three arrays should be declared to be of size 5. The index into the three arrays can be used to tie the question, answer, and point value together. For example, the item at index 0 for each array would correspond to question 1, answer 1, and the point value for question 1. Manually hardcode the five questions, answers, and point values in the constructor of TriviaGameV1. The five questions and their corresponding answers are shown on page 3. The point values should be set to 1, 2, 2, 3, 1, respectively.
The class should also provide the following two public methods:
• public boolean askNextQuestion() - This method takes no argument and returns a boolean. If there are no more questions to ask, it returns false. Otherwise, it asks the next question and gets an answer from the user. If the player’s answer matches the actual answer (case insensitive comparison), the player wins the number of points for that question. If the player’s answer is incorrect, the player wins no points for the question and the method will show the correct answer. It returns true after Q & A have been processed.
• public void showScore() - This method takes no argument and returns void. It displays the current score the player receives thus far.
The test driver is provided below, which creates a TriviaGameV1 object. After the player has answered all five questions, the game is over.
public class TriviaGameV1Test {
public static void main(String[] args) { TriviaGameV1 game = new TriviaGameV1();
while (game.askNextQuestion()) game.showScore(); System.out.println("Game over! Thanks for playing!"); }
}
Answer:
Explanation:
The following code is written in Java, It creates the class for the Trivia game along with the arrays, variables, and methods as requested so that it works flawlessly with the provided main method/test driver. The attached picture shows the output of the code.
import java.util.Arrays;
import java.util.Scanner;
class TriviaGameV1 {
String[] questions = {"The first Pokemon that Ash receives from Professor Oak is?", "Erling Kagge skiied into here alone on January 7, 1993", "1997 British band that produced 'Tub Thumper'", "Who is the tallest person on record (8 ft. 11 in) that has lived?", "PT Barnum said \"This way to the _______\" to attract people to the exit."};
String[] answers = {"pikachu", "south pole", "chumbawumba", "robert wadlow", "egress"};
int[] points = { 1, 2, 2, 3, 1};
int score;
int count = 0;
public void TriviaGameV1() {
this.score = 0;
}
public boolean askNextQuestion() {
if (count != 5) {
Scanner in = new Scanner(System.in);
System.out.println(questions[count]);
String answer = in.nextLine().toLowerCase();
if (answer.equals(answers[count])) {
score += points[count];
} else {
System.out.println("Wrong, the correct answer is : " + answers[count]);
}
count += 1;
return true;
}
return false;
}
public void showScore() {
System.out.println("Your Score is: " + this.score);
}
public static void main(String[] args) {
TriviaGameV1 game = new TriviaGameV1();
while (game.askNextQuestion()) {
game.showScore();
}
System.out.println("Game over! Thanks for playing!");

Which of the following statements is TRUE of a peer-to-peer network?
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
B. In a peer-to-peer network, all files being shared are kept on one server. Anyone who wants to access one of those files can get it directly from the server.
C. A peer-to-peer network can create heavy traffic and makes download times increase significantly.
D. Creating a directory of which computers have certain files is an acceptable practice.
Answer:
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
Explanation:
CORRECT
Choice 'A' is very true. There have been many arguments and court cases over what content can and cannot be shared through a peer-to-peer network. Users of these networks often argue that free speech allows us to share whatever we want online. Content creators on the other hand frequently sue for copyright infringement.
INCORRECT
Choice 'B' is describing a centralized system, not a peer-to-peer network. In a peer-to-peer network, there is no central location of files. Files are transferred directly from one computer to another without a middleman.
Choice 'C' is also not true of peer-to-peer networks. These networks are actually much more efficient than centralized systems because there is no large server holding all the files. It takes less time to download files from a peer-to-peer network because there is no centralized source of information and files.
Choice 'D' is also false; this was decided in the court case about Napster, one of the first large peer-to-peer networks. Having a centralized directory of who has which files is not considered free speech.
The peer-to-peer network is said to have varying views that form the basis of what can and cannot be shared. Thus, option A is correct.
What is a peer-to-peer network?A peer-to-peer network is given as the connection of the computers that are linked with the following same responsibilities and permissions.
The network is said to have varying views. Many debates and court cases have erupted over what content can and cannot be shared over a peer-to-peer network.
Users of these sites frequently argue that freedom of speech allows us to share whatever we want on the internet.On the other hand, content creators frequently file copyright infringement lawsuits.Thus, option A is correct.

SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts over TCP. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. Suppose you wish to build a packet filter rule set allowing inbound and outbound SMTP traffic. You generate the following rule set:
Rule Direction Src Addr Dest Addr Protocol Dest Port Action
A In External Internal TCP 25 Permit
B Out Internal External TCP >1023 Permit
C Out Internal External TCP 25 Permit
D In External Internal TCP >1023 Permit
E Either Any Any Any Any Deny
Required:
Describe the effect of each rule.
Answer:
The five rules are described as follows:
Rule A permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule B permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule C permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule D permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule E does not perform any action. Thus it is when the action is denied.
Explanation:
Rule A allows information transfer of the incoming email from the external server to the internal remote server, thus this allows an inbound connection.
Rule B allows information transfer of the incoming email from the remote server to the external remote server, thus this allows an inbound connection.
Rule C allows information transfer of outgoing email from the external server to the internal remote server, thus this allows an outbound connection.
Rule D allows information transfer of the outgoing email from the remote server to the external remote server, thus this allows an outbound connection.
Rule E does not allow any action in either direction thus it is when action is denied.
