Hello and welcome.

2
00:00:01,740 --> 00:00:10,740
In this lecture I'm going to explain how the for loop works in the Ruby programming language.

3
00:00:11,460 --> 00:00:16,440
What does a four loop do for a loop.

4
00:00:16,440 --> 00:00:25,820
Basically it is use when the number of iterations is known before it enters the loop.

5
00:00:25,830 --> 00:00:36,770
What that means is that the present value of a for loop is the value iterated over on less.

6
00:00:36,870 --> 00:00:43,550
A break is you some time with any form should be put in a loop you can use a break to break the loop.

7
00:00:43,560 --> 00:00:46,480
So what this is saying is there's no break.

8
00:00:46,560 --> 00:00:48,750
There is someone family for the four look.

9
00:00:48,960 --> 00:00:51,980
Is in value iterated over.

10
00:00:52,380 --> 00:00:55,540
So we're going to see how that works.

11
00:00:55,680 --> 00:01:05,280
Also a for loop is like it will happen that you don't have to use the to do option is optional you don't

12
00:01:05,280 --> 00:01:13,440
need to use the key word for looks is rarely use in modern Ruby programs.

13
00:01:13,800 --> 00:01:15,180
So let's look at.

14
00:01:15,180 --> 00:01:17,530
He'd be a syntax.

15
00:01:17,650 --> 00:01:26,370
So we've got a 4 key word followed by airable which could be Hillary and then you won't be on clits

16
00:01:26,490 --> 00:01:28,450
in the hurry.

17
00:01:28,530 --> 00:01:31,860
The for loop will iterate.

18
00:01:31,860 --> 00:01:39,120
True and that based on the expression you set it to execute what I could.

19
00:01:39,340 --> 00:01:43,410
In that block and then the statement ends.

20
00:01:43,590 --> 00:01:45,320
So let's see how that works.

21
00:01:45,590 --> 00:01:52,000
I have got my interactive Ruby first and I want to do is define an array.

22
00:01:52,090 --> 00:01:56,170
I'll say Hey Jake was too.

23
00:01:56,940 --> 00:02:02,340
I've seen one to three.

24
00:02:04,280 --> 00:02:12,030
Four five six seven.

25
00:02:12,290 --> 00:02:13,690
Are close.

26
00:02:13,940 --> 00:02:16,770
Mary and the arrow is now closed.

27
00:02:16,790 --> 00:02:20,910
We've got a very there or seven up.

28
00:02:21,410 --> 00:02:25,660
So I'm going to use a for loop to iterate.

29
00:02:25,820 --> 00:02:26,630
True.

30
00:02:28,190 --> 00:02:37,120
Remember a for loop basically knows what he's going to eat right before he goes into the loop.

31
00:02:37,220 --> 00:02:45,880
So one time went up and went to see x 4 to define a for loop for X..

32
00:02:47,330 --> 00:02:50,620
In that.

33
00:02:51,110 --> 00:02:53,320
We know the area has got seven outlets.

34
00:02:53,330 --> 00:02:56,660
I'm just going to list all of them.

35
00:02:56,790 --> 00:03:04,630
Here's two three four five three.

36
00:03:09,950 --> 00:03:12,180
Seven.

37
00:03:12,480 --> 00:03:22,140
So we've got all the members on that Arey that the value that X is going to loop through then here is

38
00:03:22,140 --> 00:03:25,510
where we'll put the statement they could.

39
00:03:25,500 --> 00:03:27,530
They're all executed.

40
00:03:27,910 --> 00:03:30,940
So what I want I want it to.

41
00:03:31,560 --> 00:03:35,360
I just wanted to add put the value of that x.

42
00:03:35,370 --> 00:03:46,110
So how it goes to the Aries I want it to list the objects in that hurry so I just see it if I press

43
00:03:46,230 --> 00:03:52,320
end now and press enter it should list all the members of that Hurry.

44
00:03:52,410 --> 00:03:56,660
As you can see it's listed all of them so there's busiek we.

45
00:03:56,700 --> 00:03:59,180
How a fawn Look works.

46
00:03:59,370 --> 00:04:00,690
Thanks for watching.

47
00:04:00,690 --> 00:04:01,510
Bye for now.
