Thank you We sneak Then here's your shmoop du jour

00:06

brought to you by diabolical older siblings who abuse their

00:10

power Yeah all right Consider the following code which generates

00:15

ten random test scores between zero and a hundred then

00:18

finds and prince thie average score The program is to

00:22

be rewritten with procedural abstraction Which of the following methods

00:28

would be part of an effective implement patient I hear

00:32

it's code public static Get some all right in here

00:37

Your potential answers Ambrose wait I recall that procedural abstraction

00:45

is the process of breaking down a program into smaller

00:49

building blocks that can be implemented A separate methods for

00:53

these three options are smaller pieces of the main program

00:57

So none are totally incorrect It's like being assigned a

01:00

big chore by your parents but not wanting to do

01:02

the work You assigned smaller past your little siblings It's

01:05

jordan Then we've all been there All right if we

01:07

look at the original program closer there are three processes

01:11

generating the scores summing the scores and printing the average

01:16

Well Ideally we should split these three tasks into separate

01:19

methods and then call them from the main function Well

01:23

option one fulfills the first process of generating scores It's

01:26

a correctly implemented piece of the program Option two fulfills

01:29

the process of summing the scores So it's also a

01:32

correct implementation However option three is not an ideal implementation

01:38

of procedural extraction Notice that it uses a four loop

01:41

to get the sum of the scores Also noticed that

01:44

this is the same exact code is an option to

01:46

the method could have made a call to get some

01:49

method saving lines of code And following the guide of

01:52

procedural in traction for this league's asked choice dsr answer

01:56

And next time we'll look into the uprising of the 00:01:59.804 --> [endTime] ship
