Answer:
Primary storage also called as main memory. RAM is an example of primary memory.
Secondary storage are popular as we use them for permanent storage.
Explanation:
Primary storage are temporary such RAM which are required for your program to execute. Without these storage, we can't use the computer for any operations. These memory keeps intermediate data and garbage out when the data no longer required.
On the other hand, when we need to store the data for future reference such as files, photos and videos we use secondary storage devices such as usb drive, hard disk etc.
Give a real-world example of a selection control structure.
An example of selection structure is when a group of people wanted to know the exact number of days through the use of a data set that has the daily high temperature which ranges from above 80 degrees, and as such, a programmer can use the if-end statement.
What is an if statement?An IF statement is known to be a kind of statement that is executed due to the happening of a specific condition.
Note that IF statements must start with IF and end with the END.

If this answer helped consider rating and marking brainliest :)
Answer:
user_num >= 0 or 0 <= user_num
Explanation:
You want to use one of the comparison operators, to solve this problem, and in this case you're going to specifically use: >= or <=, which is "greater than or equal to" and "less than or equal to", either can be used, it just depends where you place the numbers, kind of like how 10 >= 3 and 3 <= 10 are both true.
So in this case it says "non negative" number, this means that the number is greater than or equal to 0, The reason the equal to is included is because 0 is not negative. this means that you want to include it as well. So don't do user_num > 0, since that would exclude 0, which is not negative. So you're solution for the while loop will be:
while user_num >= 0:
# code
or you can do
while 0 <= user_num:
# code
Although I would probably go with user_num >= 0, since it seems to be the most understandable at a glance, although both should work.

(Depending on your C++ development tool, you may need to open the project/solution file first.) The program should calculate the average stock price stored in the prices array. It then should display the average price on the screen. Complete the program using the for statement. Save and then run the program.

I would use a for loop cycling through the array and adding the arrays values into a variable, then keep track of how many items in the array you have. Finally divide the total by the amount of stock prices and output it.

Below functions flatten the nested list of integers (List[List[int]]) into a single list and remove duplicates by leaving only the first occurrences. When the total number of elements is N, choose the one that correctly compares the time complexity with respect to N of each function.
f1 = f3 < f2
f1 = f2 < f3
f3 < f1 = f2
f3 < f1 < f2
f1 = f2 = f3
If the the total number of elements is N, the option that correctly compares the time complexity with respect to N of each function is f3 < f1 < f2.
What does it mean to flatten a list?Flattening lists is a term that connote the act of changing a multidimensional or any kind of nested list into what we call a one-dimensional list.
Note that For example, the act of changing this list of [[1,2], [3,4]] list to [1,2,3,4] is known as flattening.
So, If the the total number of elements is N, the option that correctly compares the time complexity with respect to N of each function is f3 < f1 < f2.

Pick the 3 correct Python functions that parse and output only the date and time part of each log in log.txt as follows.
parse1
parse2
parse3
parse4
parse5
Answer:
1, 4, 5
Explanation:
parse2:
. In this case it's passing "r" as an argument, which really does absolutely nothing, because whenever you call open("file.txt") it defaults to reading mode, so all you're doing is explicitly passing the "r". So let's look at the first line. Whenever you call str.split() without any arguments, by default it splits it by empty text, and filters any empty text. So str.split() is not the same as str.split(" ") although it has similar behavior. " ".split(" ") will output ['', '', '', '', '', ''], while " ".split() will output []. So in this case the line.split() will split the string '10.1.2.1 - car [01/Mar/2022:13:05:05 +0900] "GET /python HTTP/1.0" 200 2222' into the list ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']. As you can see the the data is split into two pieces of text, AND they include the brackets in both strings. So when it gets the 3 index and strips it of the "[]" it will have the incomplete date
parse3:
In this instance the "r" does nothing as mentioned before the "r" is already defaulted whenever you call open("file.txt") so open("file.txt") is the same as open("file.txt", "r"). So in this case we won't be working left to right, we're going inside the brackets first, kind of like in math you don't don't work left to right in equation 3 + 3(2+3). You work in the brackets first (inside brackets you do left to right). So the first piece of code to run is the line.split("[" or "]"). I actually kind of misspoke here. Technically the "[" or "]" runs first because this doesn't do what you may think it does. The or will only return one value. this is not splitting the line by both "[" and "]". The, or will evaluate which is true from left to right, and if it is true, it returns that. Since strings are evaluated on their length to determine if they're true. the "[" will evaluate to true, because any string that is not empty is true, if a string is empty it's false. So the "[" will evaluate to true this the "[" or "]" will evaluate to "[". So after that the code will run line.split("[") which makes the list: ['10.1.2.1 - car ', '01/Mar/2022:13:05:05 +0900] "GET /python HTTP/1.0" 200 2222']. Now the [3:5] will splice the list so that it returns a list with the elements at index 3 (including 3) to 5 (excluding 5). This returns the list: [], because the previous list only has 2 elements. There are no elements at index 3 to 5 (excluding 5). So when you join the list by " ", you'll get an empty string
parse4:
So I'm actually a bit confused here, I thought the "r+" would open the file in read-writing mode, but maybe this is a different version of python I have no idea, so I'm going to assume it is reading/writing mode, which just means you can read and write to the file. Anyways when you split the line by doing line.split(), as mentioned before it will split by empty spaces and filter any empty spaces. This line will return: ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']. and then you splice the list from indexes 3 to 5 (excluding 5). This will return the list: ['[01/Mar/2022:13:05:05', '+0900]'] which has the two pieces of information you need for the date. Now it joins them by a space which will output: '[01/Mar/2022:13:05:05 +0900]'. Now when you strip the "[]" you get the string: '01/Mar/2022:13:05:05 +0900' which is the correct output!
parse 5:
So in this example it's using re.split. And the re.split is splitting by "[" or "]" which is what re.split can be used for, to split by multiple strings, which may be confused by string.split("[" or "]") which is not the same thing as explained above what the latter does. Also the reason there is a backslash in front of the [ and ] is to escape it, because normally those two characters would be used to define a set, but by using a \ in front of it, you're essentially telling regex to interpret it literally. So in splitting the string by "[" and "]" you'll get the list: ['10.1.2.1 - car ', '01/Mar/2022:13:05:05 +0900', ' "GET /python HTTP/1.0" 200 2222'] which has 3 elements, since it was split by the [ and the ]. The second element has the date, so all you need to do is index the list using the index 1, which is exactly what the code does

A transaction has two SQL requests both successfully completed and then the data is committed. Option (d) is correct.
What do you mean by Transaction?An executed contract between a buyer and a seller to trade goods, services, or financial assets in exchange for money is known as a transaction. The phrase is also frequently used in business accounting.
Atomicity mandates that each SQL request inside a transaction be fully finished; otherwise, the transaction must be canceled. The transaction should be seen as a single, indivisible logical unit of work.
A database's atomicity assures that it adheres to the all or nothing principle. In other words, the database views each transaction as a single, complete entity. As a result, when a database processes a transaction, it either executes it in full or not at all.
Therefore, Option (d) is correct. A transaction has two SQL requests both successfully completed and then the data is committed.
