Janice usually works on a particular workbook that contains all business related data. She decides to keep a backup of all the d

quester [9]

The answer is to use the Ctrl and C keys on the keyboard to copy content from one workbook to another.

The Ctrl and C key is the standard combination keys on the keyboard that is used to copy any selected text or objects while in a user interface environment. Janice is required to press the C key while holding down the Ctrl key to copy all the content to the new workbook.

Another way of doing it is to make sure that both source and target workbooks are open. Navigate the sheets you want to copy or move in the source workbook. Click the Home tab and select then format dropdown in the Cells group. Select move or copy sheet option in the Organize sheet option. Choose the target workbook from the To Book dropdown and click OK.

8. Given the array String[] words, which already contains 1 or more values, write a block of code which counts and returns the n

Vikentia [17]

Answer:

Following are the code to this question:

public class Main//defining a class

{

public static void main(String[] arg)//defining main method

{

String[] words={"Key","day", "Know", "kind"};//defining array of String words

int x=0;//defining integer variable for count value

for(int i=0;i<words.length;i++)//defining for loop for count value

{

if(words[i].startsWith("k")||words[i].startsWith("K"))//use if block to check word start from k

x=x+1;//increment the value of x

}

System.out.print("The number of letters which starts from k is: "+ x);//print value with message

}

Output:

The number of letters which starts from k is: 3

Explanation:

In this code, inside the main method an array of String "words" is defined that hold a value, and in the next step an integer variable "x" is defined, which is used to count the letters, which starts from k.

For this, a for loop is used that counts the value and in this an, if block is defined that uses the "startsWith" method to check the value and increment the value of x and at the last, it prints its value.

Write a program to read a list of exam scores given as integer percentages in the range 0-100. Display the total number of grade

Tju [1.3M]

Answer:

import java.util.Scanner;

public class Program

{

public static void main(String [] Args)

{

int totalAGrades = 0, totalBGrades = 0, totalCGrades = 0, totalDGrades = 0, totalFGrades = 0, counter=0,maximum = 0, minimum = 9999, num, total = 0,smallest = 0,largest = 0;

Scanner in = new Scanner(System.in);

System.out.println("Enter exam percentage: ");

System.out.println("Enter a negative examScore: ");

int examScore = in.nextInt();

while(examScore > 0)

{

counter++;

if(examScore < 0){

break;}

else if(examScore > maximum){

maximum = examScore;}

else if(examScore < minimum) {

minimum = examScore;}

total = total + examScore;

if(examScore <= 50 && examScore>0)

smallest = examScore;

if(examScore > 90 && examScore <=100)

largest = examScore;

if(examScore>=90 && examScore<=100)

totalAGrades++;

else if(examScore>=80 && examScore<=89)

totalBGrades++;

else if(examScore>=70 && examScore<=79)

totalCGrades++;

else if(examScore>=60 && examScore<=69)

totalDGrades++;

else if(examScore>=0 && examScore<=59)

totalFGrades++;

examScore = in.nextInt();

}

System.out.println("Total number of scores is = " + counter );

System.out.println("Total Number of each Letter grade : " + counter);

System.out.println("Percentage of total for each letter grade : ");

System.out.println("Total number of A grades = "+ totalAGrades);

System.out.println("Total number of B grades = "+ totalBGrades);

System.out.println("Total number of C grades = "+ totalCGrades);

System.out.println("Total number of D grades = "+ totalDGrades);

System.out.println("Total number of F grades = "+ totalFGrades);

System.out.println("Lowest exam Score is :"+smallest);

System.out.println("Highest exam Score is :"+largest);

System.out.println("Average exam Score = "+ (total / counter));

}

Explanation:

Get the exam information from user as input and run a while loop until examScore is greater than zero.
Use conditional statement to check the scores of students and increment the relevant grade accordingly.
Finally display all the information including grades and scores.

The _________ attack exploits the common use of a modular exponentiation algorithm in RSA encryption and decryption, but can be

coldgirl [10]

Answer:

The answer is "timing".

Explanation:

The time attack would be a security vulnerability that enables attackers that identify computer systems or network security issues by analyzing the period of the program's reaction to multiple levels.
It is used in both RSA encryption and decryption of the modular exponentiation method but could be modified for just about any system not seem running in a fixed period.
