Answer:

Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as "low-level formatting".[1] Partitioning is the common term for the second part of the process, making the data storage device visible to an operating system.[1] The third part of the process, usually termed "high-level formatting" most often refers to the process of generating a new file system.[1] In some operating systems all or parts of these three processes can be combined or repeated at different levels[3] and the term "format" is understood to mean an operation in which a new disk medium is fully prepared to store files. Some formatting utilities allow distinguishing between a quick format, which does not erase all existing data and a long option that does erase all existing data.

As a general rule,[nb 1] formatting a disk by default leaves most if not all existing data on the disk medium; some or most of which might be recoverable with privileged[nb 2] or special tools.[4] Special tools can remove user data by a single overwrite of all files and free space.[5]

Assume the existence of a Window class with a function getWidth that returns the width of the window. Define a derived class Win

Pepsi [2]

Answer:

Following are the code in the C++ Programming Language.

//define class and inherited the parent class

class WindowWithBorder : public Window

{

//access modifier

private:

//set integer variable

int borderWidth;

//set integer variable

int windowWidth;

//access modifier

public:

//definition of the constructor that accept an integer type argument

WindowWithBorder(int);

//definition of the function

int getUseableWidth();

};

//set constructor outside the class

WindowWithBorder::WindowWithBorder(int y)

{

//initialization in integer variable from function

windowWidth = getWidth();

//initialization in integer variable from the argument list

borderWidth = y;

}

//set function from outside the class

int WindowWithBorder::getUseableWidth()

{

//return output

return windowWidth - borderWidth;

}

Explanation:

Here we define a class "WindowWithBorder" which inherit their parent class "Window", inside the class.

Set two integer data type private variables "borderWidth" and "windowWidth".
Write the definition of the "windowWidth" class constructor that accept the integer type argument list.
Write the definition of the function "getUseableWidth()" which is integer type.

Then, we define constructor outside the class which accept the integer type argument list "y" inside it.

we initialize in the variable "windowWidth" from the function "getWidth()".
Initialize in the variable "borderWidth" from the argument of the constructor.

Finally, we define function in which we perform the subtraction of the variable "windowWidth" from the variable "borderWidth" and return it.

This semester we looked at three languages (C++, Java and Python). One common rule in all three class checklists (for C++, Java

Marysya12 [62]

Answer:

The languages C++, Java, Python are Object Oriented Programming languages. What this means is that we create classes and then instantiate those classes. In C++ and Java, we use the new operator to instantiate the classes. So, if we want to display some data when we try to print the instance just like we print the variables of data types like int, double, string etc, we need to define what we need to display. It is because, class are just like data types like int, double etc. But as they are defined by the developer according to his/her needs, so the developer has to define what to print when they are printed.

Su now wants to highlight several inventors in her presentation, so she decides to use the underline color option.

Mars2501 [29]

Answer:

1. The home tab

2. Font group

3. The small arrow at the bottom right of the font command group.

4. On "Font" heading (then "All text" subheading)

Explanation:

The following explanation will help Su in accomplishing her task.

1. Go to the home tab;

2. From the home tab, Su will have access to various command groups but in her case, she needs the Font command group.

3. There's a small arrow located at the bottom left of the font command group section; clicking on this arrow will open the font dialogue.

4. On the font dialogue, there are two headings. The "font" heading and the "character spacing" heading.

In her case, she needs the "Font" heading. The font heading also has various subheadings. To access the underline colour option, she needs the "All text" subheading.

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.
