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

00:05

Brought to you by mall kiosks Whether you need a

00:08

license plate frame black light poster or misspelled custom mug

00:12

you can find everything you need here in mall kiosks

00:16

All right well it is lost in this program Where

00:19

should we put system out Print blind e t phone

00:23

home If we want output to show off the program

00:26

made it into the four loop and successfully exited the

00:29

loop here Your potential answers Posy Let's go Okay so

00:35

sounds like we're being asked where do concert up front

00:38

line statement to make sure our loops are working properly

00:41

How to make visualizing the situation a little easier Let's

00:44

insert some pseudo code where it says implementation not shown

00:49

just to give us something to work with Well pseudo

00:53

code isn't real code And if you tried running it

00:56

your compiler would have a fit it's just for our

00:58

purposes Let's say this if statement is if alien hungry

01:03

equals true well a true result will take us into

01:07

the code within the if statement there we'll find a

01:10

four loop which will set up to run ten times

01:14

Will initialize the imager eyes are counter with a value

01:17

of zero Terminate the loop when eyes less than ten

01:20

becomes false and increase the value i buy one each

01:24

time the loop runs So if alien hungry is true

01:29

we'll move on to the four loop during which we'll

01:32

call the function alien candy eat so the four loop

01:35

should run ten times then termination All right so let's

01:39

move on to the question Where should we insert print

01:41

line statement so we can confirm that we've entered the

01:44

four loop and successfully exit All right Well line two

01:48

is a definite it's right there inside the four loop

01:51

itself And that print line will occur every time the

01:54

four loop cycles flying three would also be a good

01:57

idea It's situated directly after for the four loop so

02:01

it'll run once that luke has ended It's also still

02:04

nested inside the if statement the line one is also

02:07

inside if statement but it would print before the four

02:10

loop runs which doesn't help us at all to know

02:13

whether or not the four loop is successful It sounds

02:16

like our answer is e flying two and three and

02:18

thanks for all your help E t Oh and uh 00:02:21.635 --> [endTime] thanks karl Oh
