Adding Calculator Write a program that simulates an adding machine. Input to the program will be integers, submitted one per line. Input should be handled as follows: a nonzero value should be added into a subtotal; a zero value should cause the subtotal to be printed and reset to zero; two consecutive zeroes should cause the total (not subtotal) of all the values input to be printed and the program to be terminated. Here’s an example of how the program should work. However, it is only an example. Your program should work for any test case. Input is in red and output is in blue. Your program does not need to display colors, they are show here for illustration only so that you can distinguish input and output.
The calculator program is an illustration of iteration (loop) and conditional statements
What are iterations?Iterations are program statements that are used to perform repetition operations
What are conditional statements?Conditional statements are statements used to make decisions
The main programsThe program written in Python, where comments are used to explain each action is as follows:
#This initializes the subtotal and total to 0
subTotal = 0; total = 0
#This initializes the previous number to an empty list
prevNum = []
#This iteration is repeated for valid inputs
while True:
#This gets the input from the user
num = int(input())
#This calculates the subtotal
subTotal+=num
#This calculates the total
total+=num
#If the current input is 0
if num == 0:
#This prints the sub total
print("Subtotal:",subTotal)
#This sets the sub total to 0
subTotal = 0
#If the previous number is empty
if len(prevNum) == 0:
#This sets it to the current input
prevNum.append(num)
#If otherwise
else:
#If the previous number and the current input are 0
if(prevNum[0] == 0 and num == 0):
#This prints the total input
print("Total:",total)
#This exits the loop
break
#If otherwise
else:
#This sets the previous number to the current input

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.

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

(b) -xy-
(d) - yx
Answer:
xy-1
Explanation:
Given expression is :

We need to find the value of [tex]\dfrac{dy}{dx}[/tex].
Differentiating equation (1) wrt x.
[tex]\dfrac{d}{dx}(x^2-y^2)=1\\\\2x-2y\times \dfrac{dy}{dx}=0\\\\2y\times \dfrac{dy}{dx}=2x\\\\y\times \dfrac{dy}{dx}=x\\\\\dfrac{dy}{dx}=\dfrac{x}{y}[/tex]
or
[tex]\dfrac{dy}{dx}=xy^{-1}[/tex]
Hence, the correct option is (c) "xy-1".
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.

Implement a class named Rectangle. The class should contain:
1. Two data attributes of type float named width and height that specify the width and the height of the rectangle.
2. A constructor that creates a rectangle with the specified width and height. If no argument is provided, it should use 1.0 for both values. If any input value is negative, the function should raise an exception.
3. Functions get_width and get_height that return the corresponding value
4. The set_width and set_height function that update the values if and only if the input is positive; otherwise do nothing
5. Functions get_area and get_perimeter that return the area and the perimeter of this rectangle respectively.
6. A function rotate that swaps the height and width of a rectangle object.
7. A class variable count that keeps track of the number of rectangles created so far.
8. A class method get_count that returns the above value.
9. An equality operator that returns True if and only if the two rectangles are of the same shape.
10. A __str__ function that returns the information of this rectangle in some readable format.

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.
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.
