00:00:00,690 --> 00:00:02,620
>> DAVID MALAN: Let's improve the
design of this program.

3
00:00:02,620 --> 00:00:06,090
Rather than continue to copy and paste,
or duplicate coughs, let's

4
00:00:06,090 --> 00:00:09,730
instead leverage that construct we
called a loop so as to do the same

5
00:00:09,730 --> 00:00:11,500
thing again and again.

6
00:00:11,500 --> 00:00:14,340
>> Let's first drag some of these
pieces out of our way.

7
00:00:14,340 --> 00:00:18,640
Let's grab a repeat block, and let's
change that default 10 to just 3.

8
00:00:18,640 --> 00:00:23,320
Now let me steal just one pair of this
triple of pairs, plug that into our

9
00:00:23,320 --> 00:00:25,830
loop, throw these other pieces
away altogether.

10
00:00:25,830 --> 00:00:29,080
And we've now whittled this program down
into something much simpler yet

11
00:00:29,080 --> 00:00:31,720
just as readable and
just as functional.

12
00:00:31,720 --> 00:00:36,670
Indeed, let's click the green flag, and
we get a cough, a second cough,

13
00:00:36,670 --> 00:00:39,230
and a third cough.

14
00:00:39,230 --> 00:00:40,480
Better, right?

15
00:00:40,480 --> 00:00:42,050
