1
00:00:00,060 --> 00:00:01,230
That's true statement.

2
00:00:05,520 --> 00:00:12,210
The syntax if statement is first, we type the word if then followed by the statement we need to test

3
00:00:12,210 --> 00:00:13,470
inside Brackett's.

4
00:00:23,280 --> 00:00:28,420
Keep in mind that we have to leave a space after the first break and before the second one.

5
00:00:29,790 --> 00:00:32,250
Now let's try the statement we want to test.

6
00:00:41,940 --> 00:00:45,270
We will check if age is greater than or equal 70.

7
00:00:46,090 --> 00:00:50,040
As you noticed, we use a dash GGGI for greater than or equal.

8
00:00:51,270 --> 00:00:54,510
Next step is to read the word then on a new line.

9
00:00:59,380 --> 00:01:03,790
Now, we can write all our code here if the previous statement was true.

10
00:01:13,360 --> 00:01:16,240
We can also test something else using the Eliot.

11
00:01:38,640 --> 00:01:47,010
We used a dash early for a less than or equal, if there was any other case we haven't tested, we can

12
00:01:47,010 --> 00:01:52,740
include it in our final Kelsh command and that will cover the age between 19 and 69.

13
00:02:01,790 --> 00:02:08,390
Finally, we end our live statement with the word if reversed, which will be F.I..

14
00:02:33,730 --> 00:02:41,260
We can also use the greater than less than an equal sign instead of the Daschle and Daschle, but in

15
00:02:41,260 --> 00:02:45,630
order for us to do that, we have to put our statement in double parenthesis.

16
00:02:46,630 --> 00:02:47,620
Let's try that.

17
00:03:35,930 --> 00:03:36,420
Nice.

18
00:03:37,310 --> 00:03:40,840
Now, what if we want to test two statements at the same time?

19
00:03:41,810 --> 00:03:48,470
We can do that by using the ampersand, but this time we need also to add extra brackets to our statement.

20
00:03:52,750 --> 00:03:59,570
In this example, we are testing the input we get from the user against the user name and password.

21
00:03:59,590 --> 00:04:00,730
I love Peche.

22
00:04:01,820 --> 00:04:03,220
I'm sorry, I love Besch.

23
00:04:03,880 --> 00:04:07,240
If it's true for both of them, then we print access granted.

24
00:04:07,960 --> 00:04:13,060
If even one of them is not true or both of them not true, we print access denied.

25
00:04:13,360 --> 00:04:14,140
Let's try that.

26
00:04:33,190 --> 00:04:35,170
It's working now.

27
00:04:35,190 --> 00:04:41,890
What if we want only one of them to be true this time we had the or operator or the double vertical

28
00:04:41,890 --> 00:04:42,310
bar.

29
00:04:43,990 --> 00:04:44,860
Let's try that.

30
00:05:15,940 --> 00:05:22,360
As you can see, the only case that gave us access denied was one both of them do not match.
