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

00:05

brought to you by data hiding it's Kind of like

00:08

wearing clothes You don't want anyone to see what's underneath

00:11

Okay Which of the following terms best described the process

00:14

of using methods to avoid writing repetitive code within a

00:18

function And this is an example of what kind of

00:20

development All right well each of the processes are top

00:25

down process so we can eliminate choices cnd let's go

00:29

through the differences between each step wise refinement is the

00:32

process of breaking long methods into smaller tasks doesn't quite

00:36

fit the questions description Procedural abstraction is the process of

00:40

bundling a common piece of code in a one method

00:42

so it could be used in many different places But

00:45

this fits our description nicely and let's come back to

00:47

this one Information Hiding is the process of making data

00:51

members and methods private way use information hiding so that

00:54

others cannot see our private data Not quite what we're

00:57

looking for It looks like procedural abstraction is the term

01:00

we're looking for well it's a useful tool so that

01:03

developers working together don't have to worry about fixing other

01:06

people's coats They just use the method and if it

01:09

breaks it's up to the guy who wrote it tio

01:11

deal with it Well next time we'll look at public

01:13

methods they're like the streakers you see a world cup
