Answer:
The correct answer for the following question will be A. Cipher code.
Explanation:
Cipher code:
Ciphers are potentially the cryptographic central pillar. A cipher is usually an algorithm to perform both encryption and decryption.
Secret key encryption relies on the use of symmetric ciphers. Whether the goal is to convert plaintext to ciphertext and vice-versa. The secret key is shared on both ends, and the person having the secret key can only encrypt and decrypt the data.
So, option A is a suitable answer.
In some database programs, a data file referred to as a table option (a) is correct.

<h3>The maximum discount using SQL</h3>
Product_Id Product_Name Category Price Discount Available
1 P-1 C-5 720 10 1
2 P-2 C-1 935 17 1
3 P-3 C-2 588 19 1
4 P-4 C-4 619 5 0
5 P-5 C-1 803 16 1
<h3>The Output </h3>
C-1 2 17
C-2 3 19
C-4 4 5
C-5 1 10
The code that would print the fields in SQL for the maximum discount is:
WITH newTable AS (
SELECT
t.Category,
t.Product_Id,
b.Discount as maxDiscount,
ROW_NUMBER() OVER (
PARTITION BY t.Category
ORDER BY Product_Id DESC
) AS [ROW NUMBER]
FROM Products t
INNER JOIN
(
SELECT MAX(Discount) as maxDiscount, Category
FROM Products
GROUP BY Category
) b ON t.Discount = b.Discount AND t.Category = b.Category)
select Category,Product_Id,maxDiscount from newTable
WHERE newTable.[ROW NUMBER] = 1
