00:00

Thank you We sneak and here's your smoke too Sure

00:05

brought to you by the dreaded trinidadian scorpion nightmare pepper

00:09

one drop of its juicy spicy enough to send a

00:12

horse on a spirit flat software engineer rights program composed

00:16

of many small simple functions and a few functions that

00:20

utilize small functions in order to perform more complex tasks

00:24

This is an example of which of the following and

00:28

here the potential answers roman numerals Thank you and let's

00:33

go all right Greater concept of program development refers not

00:38

so much of the actual writing of coat it's more

00:40

about designing programs overall structure on a larger scale A

00:44

few concepts that can help in planning a large coding

00:46

project are polymorphism pop down design and functional decomposition right

00:53

The first polymorphism comes from greek many and form core

00:58

shape it's the idea that a subclass can override a

01:02

method of the same name that it inherited from a

01:05

super class right So for example let's say you've got

01:09

a class called both well The classic boat comes with

01:12

a method called steer load that contains code for steering

01:16

any both object but let's say we've also got a

01:19

subclass of boat called crew shin will cruise ship also

01:23

has its own method called steer boat that overrides the

01:26

one inherited from boat and includes along with it a

01:28

new method called avoid iceberg one that way when you're

01:33

out and about your program and you have any boat

01:35

or vote subclass object whether it be a boat or

01:38

a cruise ship or raft you can call the steer

01:41

boat method and cruise ship objects will get their overriding

01:45

version of steer boat that includes avoid iceberg right it's

01:48

a useful thing to know when planning a big project

01:50

but it doesn't sound quite like the technique our engineers

01:53

used in this case All right next up top down

01:56

design pop down design is the concept of coming up

01:59

with a larger so for the program first by nailing

02:02

down the larger functions and then filling in the details

02:04

later on We get useful concept but it doesn't sound

02:07

too much like what are engineered it in this case

02:10

either Then we have functional decomposition The idea here is

02:14

to split a complex function into a lot of smaller

02:16

functions then stitch them together by calling those functions through

02:19

Larger fun well let's think about making chili chili smells

02:24

great If you were right now your chili making processes

02:27

of function in java well one way to do it

02:30

would be to write a single meandering function that handles

02:33

every part of the process from chopping vegetables Adding spice

02:38

is actually doing the cooking but that's not terribly wise

02:41

like what if your out of onions what if you

02:43

need to update the recipe the whole thing could break

02:46

and it'd be a total mess So if you were

02:48

to write a functional decomposition in mind you'd probably have

02:51

chopped vegetable is a function that would accept a variety

02:54

of variables Add spices would probably get called here and

02:57

there at chili's would get called over and over again

03:00

And then you get a research sounds an awful lot

03:03

like what our engineer did here a number of small

03:05

simple functions that get used by other functions to perform

03:09

complex tasks That's answer c room you're looking for is 00:03:14.37 --> [endTime] down the hall left three
