Answer:

Output: 2004 2008 2058  

Explanation:

In the first printf command it will print the address of the variables num, msg1, msg2. And in the second printf command it will print the values of the variables num, msg1, msg2. As the address of the structure is 2004 And the size of the integer is 4 byte so size will increase with 4 bytes and the size of character is 1 byte so it will increase by 1*50= 50 bytes.

Hence, the output is 2004 2008 2058  

Answer:

Quality of service (QOS).

Explanation:

In recent computer networking, the convergence of voice, video and text data packet has been made possible. There is no need for a dedicated network for a particular type of packet.

QOS or quality of set is a service rendered to voice or audio packets in VoIP phones to enhance communication.

The email is a digital mailing system that can be used to send all three packets. It enjoys the QOS as voice packets. It is given high preference for transmission and uses the TCP protocol to transmit data reliably.

The de-identification and data anonymization technology is provided by the organisation to user, to prevent their information to be viewed by others. It commonly used in cloud computing, communication, internet, multimedia etc. Reidentification is the reversing of the de-identification effect on personal data.

Answer:

This code fragment will run an infinite loop

Explanation:

This output: Interest 0.0 Will be displayed infinitely. The reason is because the variable year which is initially set to 0 is never updated and as such remains true because the condition is while(year<10). So at the first iteration the statement interest = (principal * year * rate) / 100; evaluates to 0 and this line of code System.out.println("Interest " + interest); prints Interest 0.0. At the next iteration the same evaluation and output takes place and on and on and on....... since the control variable is not changing.

Explanation:

In the given question there is a miss typing problem, in this question at the last line there we use "value -1 ?"  

In the question, it is defined that an array "myList" declares that includes 500 signed double words. To define this type of data first array name is used than the size of the array then the function that is "SDWORD and DUP" which defines its values, in this question except option b all are wrong that can be described as follows:

Answer:

//The Scanner class is imported which allow the program to receive user input

import java.util.Scanner;

//Class Solution is defined to hold problem solution

public class Solution {

   // The main method which signify the begining of program execution

   public static void main(String args[]) {

       // Scanner object 'scan' is defined to receive input from user keyboard

       Scanner scan = new Scanner(System.in);

       // A prompt is display asking the user to enter number of books

       System.out.println("Please enter number of books: ");

       // the user response is assigned to numberOfBook

       int numberOfBook = scan.nextInt();

       // A prompt is displayed asking the user to enter the number of days over due

       System.out.println("Please enter number of days over due: ");

       // the user response is assigned to numberOfDaysOverDue

       int numberOfDaysOverDue = scan.nextInt();

       //displayFine method is called with numberOfBook and numberOfDaysOverDue as arguments

       displayFine(numberOfBook, numberOfDaysOverDue);

   }

   //displayFine method is declared having two parameters

   public static void displayFine(int bookNumber, int daysOverDue){

       // fine for first seven days is 10cent which is converted to $0.10

       double firstSevenDay = 0.10;

       // fine for more than seven days is 20cent which is converted to $0.20

       double moreThanSevenDay = 0.20;

       // the fine to be paid is declared

       double fine = 0;

       // fine is calculated in the following block

       if(daysOverDue <= 7){

           //the fine if the over due days is less than or equal 7

           fine = bookNumber * daysOverDue * firstSevenDay;

       } else{

           // the extra days on top of the first seven days is calculated and assigned to extraDays

           int extraDays = daysOverDue - 7;

           //fine for first seven days is calculated

           double fineFirstSevenDays = bookNumber * 7 * firstSevenDay;

           // fine for the extradays is calculated

           double fineMoreThanSevenDays = bookNumber * extraDays * moreThanSevenDay;

           // the total fine is calculated by adding fine for first seven days and the extra days

           fine = fineFirstSevenDays + fineMoreThanSevenDays;

       }

       // The total fine is displayed to the user in a nice format.

       System.out.printf("The fine for " + bookNumber + " book(s) for " + daysOverDue + " day(s) is: $%.02f", fine);

   }

}

Explanation:

The program first import Scanner class to allow the program receive user input. Then the class Solution was defined and the main method was declared. In the main method, user is asked for number of books and days over due which are assigned to numberOfBook and numberOfDaysOverDue. The two variable are passed as arguments to the displayFine method.

Next, the displayFine method was defined and the fine for the first seven days is calculated first if the due days is less than or equal seven. Else, the fine is calculated for the first seven days and then the extra days.

The fine is finally displayed to the user.

Answer:

I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.

Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.

Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.

Answer:

Email.

Explanation:

Email or electronic mail is a digital messaging platform that sends digitised data through the internet to a specific or group of specified receivers.

It uses the IMAP protocol to download copies of received data from the server to the client's computer and the POP protocol to store the data only on the server, with a copy sent to the client.

The email environment provides an attachment tool to add video, image or audio files to text documents on the message to be sent across.

Answer:

import sys

# The value of the second argument is assigned to X

x = int(sys.argv[1])

# The value of the third argument is assigned to Y

y = int(sys.argv[2])

# The result of multiplication of x and y is assigned to 'result'

result = x * y

#The value of the result is displayed to the user

print("The result of multiplying ", x, "and ", y, "is", result)

Explanation:

First we import sys which allow us to read the argument passed when running the program. The argument is number starting from index 0; the name of the python file been executed is sys.argv[0] which is the first argument. The second argument is sys.argv[1] and the third argument is sys.argv[2].

The attached file is named multplyxy (it wasn't  saved as py file because the platform doesn't recognise py file); we can execute it by running: python3 multiplyxy.py 10 23

where x will be 10 and y will be 23.

To run the attached file; it content must be saved as a py file: multiplyxy.py

Answer:

For n = 100

For n = 200

For n = 400

For n = 800

The faster approach is A(Bx)

Explanation step by step functions:

A(Bx) is faster because requires fewer interactions to find a result: for (AB)x you have (n*n)+n interactions while for A(Bx) you have n+n, to understand why please see the step by step:

a) Function for (AB)x:

function loopcount1 = FirstAB(A,B,x)  

 n = size(A)(1);

 AB = zeros(n,n);

 ABx = zeros(n,1);

 loopcount1 = 0;  

 for i = 1:n

   for j = 1:n

     AB(i,j) = A(i,:)*B(:,j);

     loopcount1 += 1;

   end

 end

 for k = 1:n

   ABx(k) = AB(k,:)*x;

   loopcount1 += 1;

 end

end

b) Function for A(Bx):

function loopcount2 = FirstBx(A,B,x)

 n = size(A)(1);

 Bx = zeros(n,1);

 ABx = zeros(n,1);

 loopcount2 = 0;  

 for i = 1:n

   Bx(i) = B(i,:)*x;

   loopcount2 += 1;

 end

 for j = 1:n

   ABx(j) = A(j,:)*Bx;

   loopcount2 += 1;

 end

end

In this exercise we want to use computer and python knowledge to write the code correctly, so it is necessary to add the following to the informed code:

The correct code that corresponds to the question informed is attached in the photo and we can notice that the faster approach is A(Bx).

So knowing that the information given in the text is that;

For n = 100:

For n = 200:

For n = 400:

For n = 800:

A(Bx) exist faster cause demand hardly any interplay to find a result: for (AB)x you bear (n*n)+n interplay while for A(Bx) you bear n+n, so we have that:

a)Watching the function for (AB)x:

function loopcount1 = FirstAB(A,B,x)  

n = size(A)(1);

AB = zeros(n,n);

ABx = zeros(n,1);

loopcount1 = 0;  

for i = 1:n

  for j = 1:n

    AB(i,j) = A(i,:)*B(:,j);

    loopcount1 += 1;

  end

end

for k = 1:n

  ABx(k) = AB(k,:)*x;

  loopcount1 += 1;

end

end

b) Watching the function for A(Bx):

function loopcount2 = FirstBx(A,B,x)

n = size(A)(1);

Bx = zeros(n,1);

ABx = zeros(n,1);

loopcount2 = 0;  

for i = 1:n

  Bx(i) = B(i,:)*x;

  loopcount2 += 1;

end

for j = 1:n

  ABx(j) = A(j,:)*Bx;

  loopcount2 += 1;

end

end

Explanation:

In an entity relationship (ER) model, which is the conceptual illustration of certain entities and the relationships that exist between them, the cardinality of a relationship is the possible (minimum and maximum) number of entity occurrences that can be associated or involved in it.

Note: An entity is a real world object that is being modeled.

For example, a school has many staff members. The school and the staff members are the objects while the relationship between the school and the staff members is one-to-many.

One, many, zero are all values of cardinality.

Final answer:

The script 'parttol' reads a data file with part numbers and weight tolerances, prompts for a weight input, and assesses if it's within range, providing feedback on part validity.

Explanation:

The question involves writing a script parttol for reading a data file named parttolerance.dat which contains part numbers and their respective weight tolerance ranges. The script should then prompt the user for a weight input and determine if that weight is within the range specified for a part number.

Here's a pseudocode outline for the parttol script:

The execution of this script provides feedback to the user about the validity of the part's weight, thereby ensuring quality control in a manufacturing or engineering context.

Answer:

Before redundancy :100101011100

After checking parity redundancy: 100101010011

Explanation:

First calculate redundant bits ,

We know that the number of redundant bits can be calculated using the following formula:

2^r ≥ m + r + 1

r = redundant bit, m = data bit

total data bits = 8

so ,

2^4 ≥ 8 + 4 + 1

16 ≥ 13

so, redundant bits is 4

Now let they denoted by r1, r2, r4, and r8, as the redundant bits are placed at positions corresponding to power of 2:    1, 2, 4, and 8.  

All the redundant bits are initialized by zero.

For the data word 10011011, we can let  the bits of the data word as  w8,w7, w6, w5, w4, w3, w2, w1

Now , put data bits and redundancy bits  as follows.

d12  d11  d10  d9  d8   d7  d6  d5  d4  d3  d2  d1

w8   w7  w6  w5   r8  w4  w3  w2 r4   w1   r2  r1

 1      0    0      1      0     1     0     1    0    0    0   0

r1 = d1  xor  d3  xor d5  xor d7  xor  d9  xor d11

r1 =  0  xor  0  xor 1  xor 1  xor  1  xor 0

r1 =  1

r2 = d2  xor  d3  xor d6  xor d7  xor  d10  xor d11

r2 = 0  xor  0  xor 0  xor 1  xor  0  xor 0

r2 = 1

r4 = d4  xor  d5  xor d6  xor d7  

r4 = 0  xor  1  xor 0  xor 1

r4 = 0

r8 = d8  xor  d9  xor d10  xor d11   xor d12

r8 = 0  xor  1  xor 0  xor 0 xor  1

r8 = 0

So, the data transferred is

d12  d11  d10  d9  d8   d7  d6  d5  d4  d3  d2  d1

w8   w7  w6  w5   r8  w4  w3  w2 r4   w1   r2  r1

 1      0    0      1      0     1     0     1    0    0    1   1

The bits give the binary number as 0011 whose decimal representation is 3. Thus, the bit 3 contains an error. To correct the error the 3th bit is changed from 1 to 0.

Final answer:

To encode the 8-bit information word 10011011 using the Hamming code and even parity, we would need to insert parity bits into specific positions, resulting in a 12-bit code word composed of the original data and additional parity bits.

Explanation:

The Hamming code is a data protection algorithm used for error detection and correction. To find the Hamming code for the 8-bit information word 10011011 using even parity, you would need to insert parity bits at positions that are powers of 2 (i.e., positions 1, 2, 4, 8,...).

For each parity bit, you would determine whether the number of bits in positions it checks (including itself) is even or odd. In this case, if the number is odd, you would set the parity bit to 1 to achieve even parity, otherwise, set it to 0.

Without working through a specific example, the resulting codeword would be a 12-bit word consisting of the original 8 information bits and an additional 4 parity bits (since 8-bit data would require 4 parity bits for the Hamming encoding).

Counter-controlled repetition requires a condition to determine when the loop should stop, involving initializing a counter, setting a condition for it, and updating the counter within the loop. No boolean or method is strictly required, just the condition.

The question asks which of the following is required for counter-controlled repetition. The correct answer is C. a condition. In computer programming, counter-controlled repetition requires a condition to determine when the repetition should stop. This involves initializing a counter to a starting value, setting a condition for the counter (such as counter < 10), and updating the counter within the loop (often incrementing or decrementing). This loop continues to execute as long as the condition evaluates to true.

For example, in a for loop, you might see something like for(int i = 0; i < 10; i++), where i is the counter, i < 10 is the condition that must be true for the loop to continue, and i++ updates the counter. No boolean or method is strictly required for this process, just the condition that guides the repetition.
