Answer:
Structured programming also known as Modular programming in which the program is made as a single structure.The execution is instruction by instruction.It mainly focuses on improving the quality,clarity and development time of a computer program.
The top-down approach works by breaking a complex algorithm into smaller parts called modules. The modules keep breaking until there is no space left for breaking them without hindering the originality.The breaking of the modules is prohibited after achieving a certain level of modularity . C language uses this approach.
Bottom up works exactly opposite of how the top-down approach works.This approach works in the most elemental level of solving a problem and going up with combination of several parts of the solution to achieve required results. 
 
        
             
        
        
        
Answer:
Its the VLookup and the HLOOKUP.
Explanation:
And it depends upon the manner in which the marks are mentioned. If they are mentioned in row then we use Hlookup, and if in columns then we use vlookup.
And the syntax for vlookup is :
vlookup(lookup value, range containing the lookup value, column number in range containing the return value, approximate 0 or exact value 1)
 
        
             
        
        
        
The S3 encryption, <u>Server-Side Encryption with Customer-Provided Keys (SSE-C)</u>, allows the company to leverage Amazon S3 for storing data with given constraints. 
What do you mean by S3 encryption?
S3 encryption <u>encrypts your </u><u>data </u><u>when it is written to disks in its </u><u>data </u><u>centers at the </u><u>object </u><u>level and decrypts it for you when you </u><u>access </u><u>it.</u> There is no distinction between accessing encrypted or unencrypted items as long as you authenticate your request and you have access permissions. 
S3 encryption<u> </u><u>encrypts an item before saving it to disk when you use server-side </u><u>encryption</u><u>; the </u><u>object </u><u>is then decrypted when you download the object</u>. S3 encryption lets you safeguard the data you store in AWS S3 buckets online, which is crucial for sensitive data.
