Some scientists hypothesize that Earth's ozone layer is being damaged by the emission of certain chemical compounds known as ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs).
b. chlorofluorocarbonsWhat are ozone-depleting substances (ODS)?These substances have been widely used in various industrial processes, aerosol propellants, refrigerants, and fire suppression systems. When released into the atmosphere,
CFCs can reach the stratosphere and interact with ozone molecules, leading to their depletion and thinning of the ozone layer. Ultraviolet radiation is a consequence of ozone layer depletion, and global warming, while impacting the Earth's climate, is not directly linked to ozone layer damage.
Plant life on Earth plays a vital role in oxygen production and carbon dioxide absorption but is not a direct cause of ozone layer depletion.

Your task is to write a program that parses the log of visits to a website to extract some information about the visitors. Your program should read from a file called WebLog.txt which will consist of an unknown number of lines. Each line consists of the following pieces of data separated by tabs:
IPAddress Username Date Time Minutes
Where Date is in the format d-Mon-yy (day, Month as three letters, then year as two digits) and Time is listed in 24-hour time.
Read in the entire file and print out each record from April (do not print records from other months) in the format:
username m/d/yy hour:minuteAM/PM duration
Where m/d/yy is a date in the format month number, day number, year and the time is listed in 12-hour time (with AM/PM).
For example, the record:
82.85.127.184 dgounin4 19-Apr-18 13:26:16 13
Should be printed as something like:
dgounin4 4/19/18 1:26PM 13
At the top of the output, you should label the columns and the columns of data on each row should be lined up nicely. Your final output should look something like:
Name Date Time Minutes
chardwick0 4/9/18 5:54PM 1
dgounin4 4/19/18 1:26PM 13
cbridgewaterb 4/2/18 2:24AM 5
...(rest of April records)
Make sure that you read the right input file name. Capitalization counts!
Do not use a hard-coded path to a particular directory, like "C:\Stuff\WebLog.txt". Your code must open a file that is just called "WebLog.txt".
Do not submit the test file; I will use my own.
Here is a sample data file you can use during development. Note that this file has 100 lines, but when I test your program, I will not use this exact file. You cannot count on there always being exactly 100 records.
Hints
Make sure you can open the file and read something before trying to solve the whole problem. Get your copy of WebLog.txt stored in the folder with your code, then try to open it, read in the first string (195.32.239.235), and just print it out. Until you get that working, you shouldn't be worried about anything else.
Work your way to a final program. Maybe start by just handling one line. Get that working before you try to add a loop. And initially don't worry about chopping up what you read so you can print the final data, just read and print. Worry about adding code to chop up the strings you read one part at a time.
Remember, my test file will have a different number of lines.
You can read in something like 13:26:16 all as one big string, or as an int, a char (:), an int, a char (:), and another int.
If you need to turn a string into an int or a double, you can use this method:
string foo = "123";
int x = stoi(foo); //convert string to int
string bar = "123.5";
double y = stod(bar); //convert string to double
If you need to turn an int or double into a string use to_string()
int x = 100;
string s = to_string(x); //s now is "100"

Three friends decide to rent an apartment and split the cost evenly. They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. If rent is $650 per month, how much was the security deposit?
a.
$10
b.
$207
c.
$620
d.
$1,270
Please select the best answer from the choices provided
Answers
Answer:
c. $620
Explanation:
To find the cost of the security deposit, we need to subtract the amount paid towards the first and last month's rent from the total move-in cost.
Each friend paid $640 towards the total move-in cost, which includes the first and last month's rent and the security deposit. Since they split the cost evenly, the total move-in cost is 3 times $640, which is $1920.
The monthly rent is $650 per month, so the first and last month's rent combined is 2 times $650, which is $1300.
To find the security deposit, we subtract the first and last month's rent from the total move-in cost:
Security deposit = Total move-in cost - First and last month's rent
Security deposit = $1920 - $1300
Security deposit = $620
Therefore, the security deposit was $620.
Option c. $620 is the correct answer.

Is it possible to compare 2 pre-packaged versions in cpi?
Answers
Yes, it is possible to compare two pre-packaged versions in the Consumer Price Index (CPI), but it can be challenging due to certain limitations of the index.
The CPI is designed to measure changes in the overall price level of a basket of goods and services consumed by households.
It focuses on broad categories and representative items within those categories, rather than specific versions of products.
When it comes to pre-packaged versions of products, there can be variations in size, quality, branding, and other attributes that may affect their prices differently.
These variations make direct comparisons complex within the framework of the CPI.
To compare two specific pre-packaged versions within the CPI, it would require detailed data on their specific characteristics and how they align with the representative item in the CPI basket.
This level of granularity may not be readily available in the public domain or within the CPI methodology.

Answers
Answer:
The correct answer is option C. "its axis is tilted".
Explanation:
The axis of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane. This tilt results in the Earth receiving different amounts of energy from the Sun in each hemisphere and having its characteristic seasons. This phenomena is explained by how the Earth responds to its axis being tilted, which is by traveling in a loop around the Sun each year.
