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

brought to you by diabolical older siblings who abuse their

power Yeah all right Consider the following code which generates

ten random test scores between zero and a hundred then

finds and prince thie average score The program is to

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

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