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
