Hello and welcome to this lecture.

2
00:00:03,110 --> 00:00:11,900
In this lecture I'm going to explain with a couple of logical operators how that can be used in.

3
00:00:11,940 --> 00:00:14,180
Be Ruby programming language.

4
00:00:14,520 --> 00:00:19,690
These are logical operators that use quite frequently.

5
00:00:19,800 --> 00:00:24,700
There are a lot more logical operators you can use with the Ruby programming language.

6
00:00:24,720 --> 00:00:28,910
I'm just focussing on two in this lecture.

7
00:00:29,580 --> 00:00:35,030
Here's a table of a couple of logical operators.

8
00:00:35,040 --> 00:00:36,600
The first is core.

9
00:00:36,640 --> 00:00:37,140
And.

10
00:00:37,180 --> 00:00:42,390
And this symbol is represented by this two symbol here.

11
00:00:42,400 --> 00:00:50,130
The abassi And we've got the all represented by the pipe symbol the pipe symbol is basically next to

12
00:00:50,160 --> 00:00:53,580
the Z attack on the keyboard.

13
00:00:53,860 --> 00:00:59,330
And reuse in an English keyboard and he's just next to the letter set.

14
00:00:59,370 --> 00:01:05,850
The key to this if you want to get the pipe you call down shift and you just press the button and it

15
00:01:05,850 --> 00:01:10,360
should give you the pipe squat a pipe symbol.

16
00:01:10,720 --> 00:01:12,660
Or let's have a quick look.

17
00:01:12,660 --> 00:01:15,050
Let's go out the example here.

18
00:01:15,480 --> 00:01:18,660
So look at the first.

19
00:01:18,950 --> 00:01:27,210
So got a variable here called X with a value or form another called Y with a value of six so I'm doing

20
00:01:27,210 --> 00:01:28,350
some comparison.

21
00:01:28,350 --> 00:01:34,320
Here I am saying the variable y which is six is less than 10.

22
00:01:34,380 --> 00:01:45,530
That part of it is true and then up 10 and the variable x which has a value of 4 is greater than 1.

23
00:01:45,750 --> 00:01:48,060
So if this were a value it to be true.

24
00:01:48,270 --> 00:01:58,290
So I am comparing two different variables using the and operator which is a logical operator in the

25
00:01:58,350 --> 00:01:58,730
OR.

26
00:01:58,770 --> 00:02:07,620
Example I got a variable y and I'm saying this variable is equal to Phi.

27
00:02:09,090 --> 00:02:15,200
Or the pipes in bombings or x is equal to 3.

28
00:02:15,450 --> 00:02:22,410
So easy to return to force because comparison using the logical operator is wrong.

29
00:02:22,780 --> 00:02:26,840
Why is fix an X is false.

30
00:02:26,840 --> 00:02:34,080
I'm saying why is equal to 5 or x is equal to 3 so boards expressions are wrong.

31
00:02:34,110 --> 00:02:38,900
So it will evaluate to Fort's saw less open aab.

32
00:02:38,920 --> 00:02:42,530
Ah Ruby interpreter.

33
00:02:43,170 --> 00:02:44,690
See how it works.

34
00:02:44,730 --> 00:02:52,620
So I've got my interactive ruby which will interpret a ruby chord for me so I'm just going to create

35
00:02:52,710 --> 00:02:54,150
a couple of varied books.

36
00:02:54,150 --> 00:02:56,870
First would be variable chord X..

37
00:02:57,120 --> 00:03:00,400
I'm going to give you that value of.

38
00:03:01,050 --> 00:03:09,620
For a great unknown variable why I give that value of 6.

39
00:03:09,780 --> 00:03:17,610
So now I'm going to make some comparisons Oh using the logical operator so I'm going to see the value

40
00:03:17,700 --> 00:03:19,180
of y.

41
00:03:20,700 --> 00:03:25,990
Is less than 10 which is true.

42
00:03:27,910 --> 00:03:32,990
And the value of x.

43
00:03:34,680 --> 00:03:37,880
Greater than 1.

44
00:03:38,080 --> 00:03:45,380
So I expect that to evaluate to true as you can see it returned true.

45
00:03:45,560 --> 00:03:48,130
So let's make give you an example.

46
00:03:48,160 --> 00:03:50,850
Using the OR operator.

47
00:03:51,280 --> 00:04:01,120
So I've already defined the variable so I would just say why is he cause to which is double equal to

48
00:04:01,960 --> 00:04:04,830
seek was to 5.

49
00:04:05,530 --> 00:04:07,390
He said no he's not.

50
00:04:07,640 --> 00:04:17,250
And then the pipe symbol of K or x is equal to.

51
00:04:18,400 --> 00:04:26,670
3 that will evaluate to force because X is 4 and why is 6.

52
00:04:26,800 --> 00:04:30,040
So you can see evaluate it to force.

53
00:04:30,250 --> 00:04:36,970
So this is how you basically use the logical operator ant and illogical operate.

54
00:04:37,030 --> 00:04:43,260
Or as you get more into the Ruby programming language.

55
00:04:43,420 --> 00:04:49,170
You get phamily out on how to use these logical operators.

56
00:04:49,180 --> 00:04:51,350
Thanks for watching and bye for now.
