Answer:
Abstraction refines concepts to their core values, stripping away ideas to the fundamentals of the abstract idea. It leaves the common details of an idea. Abstractions make it easier to understand code because it concentrates on core features/actions and not on the small details.
This is only to be used for studying purposes.

identify and explain 3 methods of automatically formatting documents
Answer:
Three common automatic formatting for documents are...
Margin justification- where text is aligned to both the left and right margin- producing a neat page
Paragraph justification- where paragraphs are not split as they go over the page- but are moved to the next page in one piece.
Tabular justification- where text is indented or aligned at a 'tab stop'. - to emphasise a paragraph.
The 3 methods used in Microsoft word to auto format are; Margin Justification, Tabular Justification, Paragraph Justification
What is formatting in Microsoft Word?In Microsoft word, there are different ways of formatting a text and they are;
Margin justification; This is a type of formatting where all the selected text are aligned to either the left or right margin as you go to a new page as dictated by the user.Paragraph justification; This a type of auto formatting where paragraphs are not split as they go to a new page but simply continue from where they left off.Tabular justification; This is a type that the text is indented or aligned at a 'tab stop' to possibly show a paragraph.Read more about Formatting in Microsoft Word at: https://brainly.com/question/25813601

If we ignore the audio data in a video file, a video file is just a collection of many individual frames (i.e., images). What is the main reason that a video file can achieve a much higher compression ratio than a file that contains a single image file?
Answer:
It is compressing the video file to make it smaller, but doing so without actually losing any quality
Explanation:
The main reason for a video file that can achieve a much higher compression ratio than a file that contains a single image file is that it can reduce the size of the file without affecting its quality.
What is Video compression?Video compression may be defined as a type of methodology that is significantly utilized in order to decline the size of a video file or alter the formatting of the video without compromising its quality.
The process of compression effectively permits you to reduce the number of storage resources that are needed to store videos and save costs. The importance of video compression includes smaller overall file sizes.
Therefore, the main reason for a video file that can achieve a much higher compression ratio than a file that contains a single image file is that it can reduce the size of the file without affecting its quality.

Answer:
x=5.8
x=7.8
x=7.8
Explanation:
I repaired the code somewhat (see below).
Since x is passed as a reference variable to the sub function, inside sub() the original variable is modified, so the changed value affects the variable declared in main().
If you would remove the & in sub, this wouldn't happen, and the variable in main would keep its value 5.8.

A. SoccerPlayers playerObject=new SoccerPlayers(); An object of a derived class cannot be created.
B. playerObject.setName("Jessica Smith"); setName() is not declared in SoccerPlayers.
C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.
D. Players newPlayers=new Players(); An object of a base class cannot be created.
Answer:
C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.
Explanation:
The main method in this code will case an error when trying to run the following line of code...
leagueName=newPlayers.getLeague();
This is because the method getLeague() is being called on a Player object which takes all of its methods from the Player class. Since getLeague() is not a method located in the player class then it cannot be called by an object from that class. Especially since the Player class does not extend to the SoccerPlayers class where the getLeague() method is actually located. Instead, it is the SoccerPlayers class which extends the Players class as its parent class.
Explain, step by step the process required to carry out drive error correction (disk check) on Windows 10
Explanation:
Disk Error Checking in Windows 10
In Windows 8, Microsoft has redesigned chkdsk utility – the tool for detecting and fixing disk corruption. In Windows 8, Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility.
The disk is periodically checked for file system errors, bad sectors, lost clusters, etc., during Automatic Maintenance and you now no longer need to really go and run it. In fact, Windows 8 now even exposes the state of the file-system and disk via the Action Center or under the Drive properties in File Explorer. If potential errors are found, you will be informed about it. You can continue to use the computer, while the scan is carried out in the background. If errors are found, you may be prompted via a notification to restart your computer.
Read: How to cancel ChkDsk in Windows.
Windows found errors on this drive that need to be repaired
At times you may see a message – Windows found errors on this drive that need to be repaired. If you see it, you may want to manually run a scan. Earlier you had to schedule Disk Error Checking for the system drive and for drives which had files or processes or folders opened. In Windows 10/8, error checking starts right away, even on the system drive – and it longer needs to be scheduled at start-up. Only if some errors are found, will you have to restart to let Windows 10/8 fix the errors.
How to run CHKDSK in Windows 10
To begin the scan, right-click on the Drive which you wish to check and select Properties. Next, click on Tools tab and under Error-checking, click on the Check button. This option will check the drive for file system errors.
If the system detects that there are errors, you will be asked to check the disk. If no errors are found, you will see a message – You don’t need to scan this drive. You can, nevertheless, choose to check the drive. Click on Scan drive to do so.
explain five unique features of word processor
Explanation:
Typing, editing and printing different types of document . Formatting text , paragraph , pages for making attractive document .Checking spelling and grammar of document for making it error free.Inserting and editing picture , objects,etc. Adding watermark, charts,quick flip , etc1) Easy Typing : In MS Word, typing is so easy because :
we need not click enter button after the end of a line as in case of type writer. The word processor itself takes the matter to the next line of the document. This facility is called word wrapping.There is no limit for typing the matter in word processing. You can type the matter continuously without resorting to new page or file. But in a type writer, if you complete a page, you have to take another blank page and start typing.You can easily rectify mistakes as the typed matter appears on the screen.2) Easy : The document so typed can be stored for future use. The process of storing is called saving. We can preserve the document for any number of years in word processing.
3) Adding, Removing and Copying Test : Documents can be modified easily in MS Office. We need not strike off any word as in the case of type writer. We can easily place a new word in place of existing one. The new word or paras will automatically be adjusted in the place of deleted or modified text. We can also copy a part or whole of the matter from one file or document to another document.
4) Spell Check of words : The spellings of words in the document can be rectified automatically. We can find alternative words to our typed words. Not only that, even the grammatical errors can also be rectified in word processor.
5) Change the Style and Shape of Characters and Paragraphs : The documents in word processor can be made attractive and appealing because the shape and style of characters or letters in the documents can be changed according to our requirements. You can even change the gap between one line and other line in the document. This process is called line spacing. Not only the lines but also paragraphs can be aligned to make it more appealing to the readers. This facility is called alignment in word processing.

Sentence Deobfuscate Name this file deobfuscate.cpp Hints: Don’t overthink this problem. Prompt the user to enter a collection of sentence words (i.e., words in the sentence), with the spaces removed (i.e., the obfuscated sentence) and with words that are less than ten (10) letters each. Then prompt the user to enter a sequence of numbers that represent the length of each corresponding sentence word (i.e. the deobfuscated details). Output the deobfuscated sentence. Convert char c to int by subtracting 48 (‘0’) from c.
Sample Execution:
Please enter obfuscated sentence: Thisisasentence
Please enter deobfuscation details: 4218
Deobfuscated sentence: This is a sentence
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
string text,lengt;
cout<<"Please enter obfuscated sentence: "; cin>>text;
cout<<"Please enter deobfuscation details: "; cin>>lengt;
string t1, t2;
int kount = 0;
for(int i = 0;i<lengt.length();i++){
kount+=(int)(lengt[i]-'0');
t1 = text.substr(0, kount);
t2 = text.substr(kount, text.length()-1);
text = t1 +" "+ t2;
kount++; }
cout<<"Deobfuscated sentence: "<<text;
return 0; }
Explanation:
This declares the text and the deobfuscation details as string
string text,lengt;
This prompts for the sentence
cout<<"Please enter obfuscated sentence: "; cin>>text;
This prompts for the details
cout<<"Please enter deobfuscation details: "; cin>>lengt;
t1 and t2 are declared as string. They are used to split the texts into 2 parts
string t1, t2;
This declares and initializes a count variable to 0
int kount = 0;
This iterates through the deobfuscation details
for(int i = 0;i<lengt.length();i++){
This gets each deobfuscation character
kount+=(int)(lengt[i]-'0');
The next two instructions splits the text into 2
This gets from 0 to kount.
t1 = text.substr(0, kount);
This gets from kount to the last index
t2 = text.substr(kount, text.length()-1);
The new string or sentence is calculated here
text = t1 +" "+ t2;
The kount variable is incremented by 1
kount++; } The loop ends here
This prints the new sentence
cout<<"Deobfuscated sentence: "<<text;
See attachment for program file
Your program should include the following four functions:
check_length - This function should accept a password to evaluate as a parameter and should return a score based on the length of the password. A password that is less than 8 characters long gets a length score of 1. If it is between 8 and 11 characters long (inclusive), it gets a length score of 2. A password that is 12 characters or longer gets a length score of 3.
check_case - This function should accept a password to evaluate and return a case score of 1 or 2. If the letters in the password are all uppercase or all lowercase, the case score should be a 1. If there is a mix of uppercase or lowercase letters (or if there are no letters at all), it gets a case score of 2.
check_content - This function should accept a password to evaluate and return a content score. If the characters are all alphabetic characters, the content score is 1. If the characters include any numeric digits (either all numeric or a mix of letters and digits), the content score is 2. If there are any other types of characters (such as punctuation symbols), the content score is 3.
main - This function represents the main program. It accepts no parameters and returns no value. It contains the loop that allows the user to process as many passwords as desired. It function calls the other functions as needed, computing the overall score by adding up the scores produced by each function. All output should be printed in the main function.

Explanation:
The main begins here
def main():
This prompts the user for password
pwd = input("Password: ")
This calls the check_length function
print("Length: "+str(check_length(pwd)))
This calls the check_case function
print("Case: "+str(check_case(pwd)))
This calls the check_content function
print("Content: "+str(check_content(pwd)))
The check_length function begins here
def check_length(pwd):
This calculates the length of the password
lent = len(pwd)
If length is less than 8, it returns 1
if lent < 8:
return 1
If length is less than between 8 and 11 (inclusive), it returns 2
elif lent >=8 and lent <= 11:
return 2
If otherwise, it returns 3
else:
return 3
The check_case function begins here
def check_case(pwd):
If password contains only uppercase or only lowercase, it returns 1
if(pwd.isupper() or pwd.islower()):
return 1
If otherwise, it returns 2
else:
return 2
The check_content function begins here
def check_content(pwd):
If password is only alphabet, it returns 1
if(pwd.isalpha()):
return 1
If password is only alphanumeric, it returns 2
elif(pwd.isalnum()):
return 2
If otherwise, it returns 3
else:
return 3
This calls the main function

Description
Military time uses 24 hours for the entire day instead of 12 for am/pm separately. Military time is a 4 digit (base-10) integer with the following rules:
The first two digits show the hour (between 00 and 23) and
The last two digits show the minutes (between 00 and 59)
There is no colon separating hours from minutes.
Military time starts at 0000 in the morning and counts up
When we get to the afternoon, we use 1300 for 1:00 PM and 2300 for 11:00 PM.
When we get to midnight, the hour is 00 (not 24).
TASK: Write a program that reads two times in military format and prints the number of hours and minutes between the two times (See example below).
NOTE: Your program should consider the difference between the times IN THE SAME DAY. For example: The time difference between 2359 and 0000 is 23 hours and 1 minute (NOT 1 minute).
Detailed Requirements
• Compose a written document (MS Word Document) describing your algorithm, feel free include a diagram if you like
• The program should prompt for two times separately, then print the duration of time between (see sample output below).
• The program should check the input for the correct military time format:
. Make sure the hours are between 00 and 23.
. Make sure the minutes are between 00 and 59
. If the validity check fails, it should print an appropriate error and prompt again.
• Your program should use io manipulators to produce military time with leading zeroes. e.g. 9 am should be printed 0900 (not 900).
• More points will be awarded to an implementation that can produce an accurate result regardless of the order of the inputs.
• Do not produce runtime errors that abruptly end your program (crash)
• Include descriptive comments, neat indentation, proper spacing for good readability, and appropriate and consistently named variables.
• Program source should have a comment block at the top with the student name, section, and description of your program.

how are headers and footers are useful in presentation
Answer:
Explanation:
PowerPoint is a software that allows user to create headers as well as footers which are information usually appears at the top of the slides and the information that appears at the bottom of all slides. Headers and footers are useful when making presentation in these ways:
✓ Both provide quick information about one's document/ data clearly in a predictable format. The information that is provided by the Header and footers typically consist of ;
©name of the presenters,
©the presentation title
©slide number
©date and others.
✓ They help in setting out different parts of the document.
✓Since the Headers and footers can appear on every slide, corporate confidentiality as well as copyright information can be added to footer area to discourages those that can steal ones secrete.

internet protocol?
explanation:
the set of rules governing the format of data sent via the internet or local networkC++ "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length.
Ex: The following patterns yield a userScore of 4:
Ex: The following patterns yield a userScore of 9:
simonPattern: RRGBRYYBGY
userPattern: RRGBBRYBGY
Result: Can't get test 2 to occur when userScore is 9
Testing: RRGBRYYBGY/RRGBBRYBGY
Your value: 4
Testing: RRRRRRRRRR/RRRRRRRRRY
Expected value: 9
Your value: 4
Tests aborted.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int userScore = 0;
string simonPattern, userPattern;
cout<<"Simon Pattern: "; cin>>simonPattern;
cout<<"User Pattern: "; cin>>userPattern;
for (int i =0; i < simonPattern.length();i++){
if(simonPattern[i]== userPattern[i]){
userScore++; }
else{ break; }
}
cout<<"Your value: "<<userScore;
return 0;
}
Explanation:
This initializes user score to 0
int userScore = 0;
This declares simonPattern and userPattern as string
string simonPattern, userPattern;
This gets input for simonPattern
cout<<"Simon Pattern: "; cin>>simonPattern;
This gets input for userPattern
cout<<"User Pattern: "; cin>>userPattern;
This iterates through each string
for (int i =0; i < simonPattern.length();i++){
This checks for matching characters
if(simonPattern[i]== userPattern[i]){
userScore++; }
This breaks the loop, if the characters mismatch
else{ break; }
}
This prints the number of consecutive matches
cout<<"Your value: "<<userScore;

Please use the tables in the flights database. Your deliverable should include a single SQL query that I can run against a "fresh copy" of the tables in the flights database.
1. Write a script to select all data from the planes table.
2. Update the planes table so that rows that have no year will be assigned the year 2013. (missing values will display as NULL).
3. Insert a new record to the planes table with the following values:
Tailnum: N15501
Year: 2013
type: Fixed wing single engine
Manufacturer: BOEING
Model: A222-101
Engines: 3
Seats: 100
Speed: NULL (notice this is not a text value but truly the absence of any value: "empty". As such, don't use single or double quotes around NULL when inserting this value).
Engine: Turbo-fan
4. Delete the newly inserted record on step 3.
Answer:
The scripts are:
1. SELECT * FROM planes
2. UPDATE planes SET YEAR = 2013 WHERE year IS NULL
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
Explanation:
1. SELECT * FROM planes
To select all from a table, use select * from [table-name]. In this case, the table name is planes
2. UPDATE [tex]planes\ SET[/tex] YEAR = 2013 WHERE year IS NULL
To do this, we use the update query which is as follows:
UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL
So: the above query will update all YEAR column whose value is NULL to 2014
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
To insert is very straight foward.
The syntax is:
INSERT INTO [table-name] (column names) VALUES (values)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
To do this, we use the update query which is as follows:
DELETE FROM [table-name] WHERE [column] = [value]
So: The above query will delete the entry in (3) above
