13. Which statement is valid?
1 KB = 1024 bytes.
1 MB = 2048 bytes
1 MB = 1000 kilobytes
1 KB = 1000 bytes​

Answer:

In C:

#include <stdio.h>

#include <stdlib.h>

int main() {

int r,c;

printf("Row: "); scanf("%d", &r);

printf("Cols: "); scanf("%d", &c);  

double *myarr = (int *)malloc(r * c * sizeof(int));

double inputs = 0.0;

for (int rww = 0; rww < r; rww++){

for (int ccl = 0; ccl < c; ccl++){

 inputs= inputs+1.0;

 *(myarr + rww*ccl + ccl) = inputs; }}

return 0;}

Explanation:

This declares the rows and columns as integers

 int r,c;

This gets the number of rows

printf("Row: "); scanf("%d", &r);

This gets the number of columns

printf("Cols: "); scanf("%d", &c);  

This dynamically allocate space for array myart

double *myarr = (int *)malloc(r * c * sizeof(int));

This initializes the inputs to the array to 0.0

double inputs = 0.0;

This iterates through the array and initializes each element of the array by its index

for (int rww = 0; rww < r; rww++){

for (int ccl = 0; ccl < c; ccl++){

 inputs= inputs+1.0;

 *(myarr + rww*ccl + ccl) = inputs; }}

Answer:

In Java:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 String isbn;

 System.out.print("First 1:2 digits: ");

 isbn = input.nextLine();

 if(isbn.length()==12){

 int chksum = 0;

 for(int i = 0; i<12;i++){

     if((i+1)%2==0){      chksum+= 3 * Character.getNumericValue(isbn.charAt(i));          }

     else{          chksum+=Character.getNumericValue(isbn.charAt(i));          }  }

 chksum%=10;

 chksum=10-chksum;

 if(chksum==10){

 System.out.print("The ISBN-13 number is "+isbn+"0");}

 else{

 System.out.print("The ISBN-13 number is "+isbn+""+chksum);          }   }

 else{

     System.out.print("Invalid Input");

 }     }}

Explanation:

I do not like virtual because I like to go outside.

Answer:

function removeRepeaters(list){

   var goodList = [], badList = {}, used = {}, n;

   // ensure that the argument is indeed an array

   if(!Array.isArray(list)){

        throw "removeRepeaters: Expecting one argument of type Array";

   }

   // loop through the array and take note of any duplicates

   for(n in list) used[list[n]] == true ? badList[list[n]] = true : used[list[n]] = true;

   // now loop through again, and assemble a list of non-duplicates

   for(n in list) if(badList[list[n]] == undefined) goodList[] = list[n];

   return goodList;

}

Explanation:

I assume you're familiar with trinary operators, but just in case, that's what's happening in this first for loop:

for(n in list) used[list[n]] == true ? badList[list[n]] = true : used[list[n]] = true;

this is the same as saying:

for(n in list){

   if(used[list[n]] == true){

       badList[list[n]] = true;

   } else {

       used[list[n]] = true;

   }

}

This loop flags all of the values in the list that are duplicated.  Note that both "badList" and "used" are declared as objects instead of arrays.  This allows us to compare keys in them with an == operator, even if they're not defined, making it a convenient way to flag things.

Note that I haven't tested it, so I may have overlooked something.  I suggest testing it before handing it in.

Answer:

Replace the comment with:

(c) double hours = Math.abs (marker1 - marker2) / 60.0;

Explanation:

See attachment for right presentation of question

Analyzing the options:

(a): May return a negative result

This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.

This literally is not different from marker1 - marker2

(b): Incorrect expression

This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.

(c) This option is correct

This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)

(d) & (e) Integer division

When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation

Explanation:

Leo is the parent class and jack inherits all of its attributes from Leo

So when you call the following code in the main method:

Jack j = new Jack();

System.out.println(j.method1);

it should print Jack 1 Leo 1

This is because the program first checks if method 1 exists in the Jack class

Because it doesn't exist it then goes to the parent class which is Leo.

And in the Leo class method1 displays "Jack 1 Leo 1 "

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

for i in range(1,501):

   for j in range(1,501):

       for k in range(1,501):

           print(str(i)+"\t"+str(j)+"\t"+str(k)+"\t"+str(Pythagorean_triple(i,j,k)))

Explanation:

This defines the function

def  Pythagorean_triple(hyp,side1,side2):

This checks for pythagorean triple

   if hyp**2 == side1**2 + side2*2:

Returns True, if true

       return True

   else:

Returns False, if otherwise

       return False

The main method begins

This prints the header

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

The following is a triple-nested loop [Each of the loop is from 1 to 500]

for i in range(1,501): -->The hypotenuse

   for j in range(1,501): -->Side 1

       for k in range(1,501):-->Side 2

This calls the function and prints the required output i.e. the sides of the triangle and True or False

   runagain = input("Run program again? ").lower()

   if  runagain == "y":

       repeat=True

   else:

       repeat = False

Explanation:

The function begins here

def subsmall(num1,num2):

This subtracts num2 from num1 if num2 is smaller

   if num1 > num2:

       return num1 - num2

If otherwise, subtract num1 from num2

   else:

       return num2 - num1

The main begins here

This initialiazes a boolean variable to true    

repeat = True

This loop is repeated until the boolean variable is false

while(repeat):

Prompt to enter two integers

   num = input("Enter two integers: ")

Split the string by space

   nums = num.split(" ")

This passes the two integers to the function and also prints the differences

   print(subsmall(int(nums[0]),int(nums[1])))

Prompt to run the program again

   runagain = input("Run program again? ").lower()

If input is Y or y, the loop repeats

   if  runagain == "y":

       repeat=True

The program ends if otherwise

A. The software was corrupt and resulted in a bug.

B. He purchased a license with maintenance for a year.

C. The organization discontinued the software.

D. He purchased an open-source license.

E. He purchase a perpetual non-maintenance license.

Answer:

B. He purchased a license with maintenance for a year.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Basically, softwares are categorized into two (2) main categories and these are;

I. Open-source software.

II. Proprietary software.

A proprietary software is also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer. Thus, it is typically published as a commercial software that may be sold, licensed or leased by the software developer (vendor) to the end users with terms and conditions.

In this scenario, Wesley purchased a word-processing software program. He used it for a year, during which he got regular updates every two months. However, after a year, he was not allowed to update the software but he could continue using it.

This ultimately implies that, Wesley purchased a licensed software with maintenance for a year and as such he would stop receiving an update from the software developer after his subscription expired.

Answer:

I. Improper cable installation.

II. Interference between the signals on cables close to each other.

III. Improper connection of a network cable to the jack

Explanation:

The standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. Thus, the standard Internet communications protocols which allow digital computers to transfer (prepare and forward) data over long distances is the TCP/IP suite.

In this scenario, Mark is unable to connect to the internet or to any of the computers on his network, while nearby computers don’t have this problem. Therefore, the three issues which could be causing the problem are;

I. Improper cable installation: this involves not installing the ethernet cable in the correct destination port.

II. Interference between the signals on cables close to each other: interference usually results in the disruption in network signals.

III. Improper connection of a network cable to the jack: the right connectors such as RJ45 should be used.
