}

Explanation:

Remember that the sizeof() mechanism fails if a pointer to the data is passed to a function. That's why the count variable is needed in the first place.

The following code is written in Java. It creates the method as requested which takes in a parameter of type Scanner and opens the passed file, reads all the elements, and prints the lowest-priced element in the file. A test case was done and the output can be seen in the attached picture below.

import java.io.File;

import java.io.FileNotFoundException;

import java.util.Scanner;

class Brainly{

   public static void main(String[] args) throws FileNotFoundException {

       Scanner console = new Scanner(System.in);

       System.out.print("file location: ");

       String inputLocation = console.next();

       File inputFile = new File(inputLocation);

       Scanner in = new Scanner(inputFile);

       lowestPrice(in);

   }

   public static void lowestPrice(Scanner in) {

       double smallest = in.nextDouble();

       while(in.hasNextDouble()){

           double number = in.nextDouble();

           if (number < smallest) {

               smallest = number;

           }

       }

       System.out.println(smallest);

       in.close();

Answer:

The addition to the program is as follows:    digit = 0

   while digit <= 9:

       print('%s%d.com' % (letter1, digit))

       digit+=1

Explanation:

This initializes digit to 0

   digit = 0

This loop is repeated from 0 to 9 (inclusive)

   while digit <= 9:

This prints the domain (letter and digit)

       print('%s%d.com' % (letter1, digit))

This increases the digit by 1 for another domain

       digit+=1

.isLeapYear (1900) will return an incorrect response

Explanation:

Given

The above method

Required

Which method call will give an incorrect response

(a) will return an incorrect response because 1900 is not a leap year.

When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.

Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.

Hence, (a) answers the question;

Answer:

While it may seem like we are already overwhelmed by the amount of cyberattacks occurring daily, this will not slow down in 2018. In fact, with a recent increase in cybercriminal tools and a lower threshold of knowledge required to carry out attacks, the pool of cybercriminals will only increase. This growth is a likely response to news media and pop culture publicizing the profitability and success that cybercrime has become. Ransomware alone was a $1 billion industry last year. Joining the world of cybercrime is no longer taboo, as the stigma of these activities diminishes in parts of the world. To many, it’s simply a “good” business decision. At the same time, those already established as “top-players” in cybercrime will increase their aggressive defense of their criminal territories, areas of operations and revenue streams. We may actually begin to see multinational cybercrime businesses undertake merger and acquisition strategies and real-world violence to further secure and grow their revenue pipeline.

Explanation:

Answer:

The program in Python is as follows:

n = int(input())

myList = []

for i in range(n):

   num = int(input())

   myList.append(num)

threshold = int(input())    

for i in myList:

   if i<= threshold:

       print(i,end=", ")

Explanation:

This gets the number of inputs

n = int(input())

This creates an empty list

myList = []

This iterates through the number of inputs

for i in range(n):

For each iteration, this gets the input

   num = int(input())

And appends the input to the list

   myList.append(num)

This gets the threshold after the loop ends

threshold = int(input())    

This iterates through the list

for i in myList:

Compare every element of the list to the threshold

   if i<= threshold:

Print smaller or equal elements

       print(i,end=", ")

The Python program below gets a list of integers, then filters that list based on a threshold value:

########################################################

# initialize the integer and output lists

integer_list = [ ]

output_list = [ ]

# first enter the number of integers that will follow

# and append it to integer list

qty = int(input("Enter the number of integers to follow: "))

integer_list.append(qty)

# next enter the number of integers and append them to integer list

for i in range(0, qty):

   num = int(input("Enter an integer: "))

   integer_list.append(num)

# finally enter the threshold value to be used to filter the integers

threshold = int(input("Enter the threshold value: "))

integer_list.append(threshold)

# filter the integers

for num in integer_list:

   if num <= integer_list[-1]:

       output_list.append(num)

# display the result

print("The values from { } that are less than or equal to { } are

   { }".format(integer_list[1:-1], integer_list[-1], output_list))

########################################################

The program first asks the user to enter the following:

The program next iterates over the integer list and filters the integers from index 1 to index -1(exclusive, since this is the threshold value) based on the element at index -1(the last element, the threshold value).

Each element that satisfies the filtering criterion (e <= threshold) is added to the output list and printed out later.

Answer:

num1 = 600

Explanation:

Given

The attached code snippet

Required

The output of n = funcOne(funcTwo(n));  when n = 30

The inner function is first executed, i.e.

funcTwo(n)

When n = 30, we have:

funcTwo(30)

This returns the product of n and 10 i.e. 30 * 10 = 300

So:

funcTwo(30) = 300

n = funcOne(funcTwo(n)); becomes: n = funcOne(300);

This passes 300 to funcOne; So, we have:

n = funcOne(300);

This returns the product of n and 2 i.e. 300 * 2 = 600

Hence, the output is 600

Answer:

!(key == 'q')

Explanation:

Based on the description, the coded expression that would equate to this would be

!(key == 'q')

This piece of code basically states that "if key pressed is not equal to q", this is because the ! symbol represents "not" in programming. Meaning that whatever value the comparison outputs, it is swapped for the opposite. In this case, the user would press anything other than 'q' to continue, this would make the expression output False, but the ! operator makes it output True instead.

Answer:

Virus & threat protection.

Explanation:

Monitor threats to your device, run scans, and get updates to help detect the latest threats.

One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.

BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.

By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.

BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.

Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

D. Change the def to def area (width, height = 12)

Explanation:

Required

Update the function to set height to 12 when height is not passed

To do this, we simply update the def function to:

def area (width, height = 12)

So:

In boxlarea = area (5,2), the area will be calculated as:

[tex]area = 5 * 2 = 10[/tex]

In box2area = area (6), where height is not passed, the area will be calculated as:

[tex]area = 6 * 12 = 72[/tex]

Solution :

It is given that an application is used to transmit a data record  form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.

a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.

b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer.  So for this the line of transmission can be either wired or wireless.

C. Transactions.

Explanation:

A transaction can be defined as a business process which typically involves the interchange of goods, financial assets, services and money between a seller and a buyer.

This ultimately implies that, any interaction between a seller and a buyer is called transactions.

For example, when a buyer (consumer) pays $5000 to purchase a brand new automobile from XYZ automobile and retail stores, this is referred to as a transaction.

Hence, a transaction is considered to have happened when it's measurable in terms of an amount of money (price) set by the seller.

Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.
