Hello world.
I'm going to demonstrate
a count loop in Alice3.
I have a bunny,
and I'm going to turn his head
to the left  .125
That's going to put his chin over his left shoulder.
Not quite to his left shoulder.
Then I'm going to turn it to the right
double that  distance.
so that's going to go back to the front.
and then all the way to the right to the same position
it was on the left.
then turned it to the left .125,
and he will be back in the middle.
Let's run that.
And I would like him to do that
several times.
To shake his head no.
So, I'm going to add a count loop.
And I want him to do that three times.
Notice the code declares an integer indexA,
which is starting at zero.
and the loop is going to continue
as long as that indexA
is less than three.
and then each time through the loop
I had one to indexA.
So, I want to put all of these
statements inside the loop, in the same order.
Oh,  I didn't get that inside hte loop. There we go. OK.
So let's run this.
Another thing I'm going to do is have him
The bunny, say something.
And the bunny  is going to say,
each time through the loop, No.
OK, let's run this: He says no, he says no again, he says no.
And let's add to that: plus,
the integer indexA.
I need to just... let's run this.
and he says No 0,  No 1, and No 2.
So, you can see
the values of  indexA
are 0, 1, 2.
And it never gets to 3,
because the loop ends when it gets to 3.
And so that's a count loop.
