00:00:06.930 --> 00:00:11.910
In this video we going to get introduced to BHB conditional statements.

00:00:12.780 --> 00:00:20.310
So just tell we get to write a piece of code where we are going to be checking whether a condition is

00:00:20.730 --> 00:00:27.060
true and based on that we can print something on the web page.

00:00:27.710 --> 00:00:32.490
So it create a variable we're going to call it believe in your dream

00:00:37.390 --> 00:00:39.280
and are going to set it to true.

00:00:39.690 --> 00:00:41.100
It's a billion.

00:00:41.490 --> 00:00:42.550
All right.

00:00:42.700 --> 00:00:46.830
And now we're going to check if OK

00:00:50.130 --> 00:00:53.820
if you believe in your dream.

00:00:54.000 --> 00:00:56.430
So the syntax is similar to Javascript.

00:00:56.520 --> 00:00:59.710
So we put the condition inside parentheses right.

00:00:59.820 --> 00:01:04.460
So the keyword if and after that are we.

00:01:04.500 --> 00:01:08.760
If it's true we are going to echo something with our screen.

00:01:09.380 --> 00:01:09.870
OK.

00:01:10.110 --> 00:01:17.610
So unlike javascript do you you don't have to use curly brackets but it's better to use Curl-Burke is

00:01:17.610 --> 00:01:21.380
for readability reasons.

00:01:21.380 --> 00:01:21.730
OK

00:01:23.320 --> 00:01:25.840
.

00:01:28.830 --> 00:01:33.760
And if the condition is not true then we're going to use.

00:01:33.760 --> 00:01:35.820
Else OK.

00:01:36.090 --> 00:01:37.950
And we're going to echo something else

00:01:37.970 --> 00:01:43.680
.

00:01:48.810 --> 00:01:49.080
OK

00:01:53.760 --> 00:01:58.650
so if it's true we can take for example a paragraph

00:02:01.620 --> 00:02:03.510
.

00:02:05.400 --> 00:02:10.410
You will be successful.

00:02:13.150 --> 00:02:13.850
OK.

00:02:13.960 --> 00:02:20.720
Otherwise we're going to echo believe in your

00:02:25.070 --> 00:02:28.110
in your dream to be successful

00:02:32.820 --> 00:02:33.300
in life.

00:02:33.450 --> 00:02:34.780
OK.

00:02:35.040 --> 00:02:42.030
All right so now let's save and refresh the page where you can see our resolve there because the condition

00:02:42.030 --> 00:02:48.620
is true if we said that's false then if we're fresh we can see the other message.

00:02:48.680 --> 00:02:49.550
Us.

00:02:50.250 --> 00:02:51.410
All right.

00:02:52.060 --> 00:03:01.920
OK so now we going to look at another way of setting a certain variable.

00:03:02.150 --> 00:03:07.270
Ok two different values depending on the condition.

00:03:07.500 --> 00:03:16.260
OK so rather than than we could we could use if condition then set the variable to a certain value else

00:03:16.260 --> 00:03:16.340
.

00:03:16.350 --> 00:03:18.230
So the variable to another value.

00:03:18.480 --> 00:03:20.730
But we're going to try something else.

00:03:20.730 --> 00:03:24.180
So our variable is going to be x.

00:03:24.490 --> 00:03:25.600
OK.

00:03:26.850 --> 00:03:33.210
And we are just going to set it straight away like this.

00:03:33.240 --> 00:03:40.670
So we're going to say variable x equals OK and which reimburses we're going to have our condition.

00:03:40.920 --> 00:03:42.300
Let's use the same condition.

00:03:42.810 --> 00:03:44.650
Believe in your dream.

00:03:45.750 --> 00:03:46.310
OK.

00:03:46.620 --> 00:03:50.520
And we're going to have a question mark after that.

00:03:50.550 --> 00:04:02.190
So it's like we are saying is this condition true question mark if yes OK then we want to have this

00:04:02.190 --> 00:04:06.190
value able example.

00:04:06.210 --> 00:04:10.870
Otherwise you know use caller.

00:04:11.380 --> 00:04:12.600
OK.

00:04:12.880 --> 00:04:18.520
And then we get to rights the other values right.

00:04:18.770 --> 00:04:20.130
So if you echo

00:04:23.010 --> 00:04:23.490
X

00:04:29.000 --> 00:04:37.780
Let's check we can see that X equals B because our condition is false.

00:04:37.800 --> 00:04:38.850
All right.

00:04:39.720 --> 00:04:40.630
OK.

00:04:41.100 --> 00:04:41.350
OK.

00:04:41.370 --> 00:04:53.220
Now we are going to use if else but we are going to use another key word it's else if and if we have

00:04:55.500 --> 00:04:57.590
more than two conditions so.

00:04:57.750 --> 00:05:04.170
So for example if we said the three sets a variable temperature

00:05:07.060 --> 00:05:08.430
225.

00:05:08.880 --> 00:05:09.400
OK.

00:05:09.560 --> 00:05:17.460
And then we say if the temperature is less than 15.

00:05:18.840 --> 00:05:28.930
Ok then do this else do that's what we want to check.

00:05:28.950 --> 00:05:37.110
Also if the temperature is greater than 30 and also we want to check if it's a bridge is between 15

00:05:37.320 --> 00:05:38.890
and 30.

00:05:38.910 --> 00:05:40.300
So what we're going to do going to do.

00:05:40.300 --> 00:05:41.300
Else if.

00:05:41.760 --> 00:05:41.980
OK

00:05:45.210 --> 00:05:48.990
we're going to have our condition.

00:05:49.650 --> 00:05:53.920
So temperature greater than 30.

00:05:54.690 --> 00:05:59.480
And then we have else that do that's OK.

00:05:59.790 --> 00:06:08.060
So if the temperature is less than 15 then we can rise for example echo

00:06:08.270 --> 00:06:15.200
.

00:06:19.120 --> 00:06:20.760
It is cold.

00:06:21.140 --> 00:06:25.010
OK.

00:06:29.580 --> 00:06:37.760
If it's greater than that they see it go it is hot and else echo.

00:06:37.950 --> 00:06:42.940
The temperature is medium.

00:06:44.680 --> 00:06:50.340
OK assuming that I can see the temperature is medium

00:06:54.900 --> 00:06:58.590
the temperature is between 15 and 30.

00:06:59.310 --> 00:07:00.810
OK.

00:07:01.000 --> 00:07:01.530
All right.

00:07:01.680 --> 00:07:05.840
Now we're going to move to using a switch.

00:07:06.450 --> 00:07:12.530
So as we have covered this in javascript is more or less the same syntax.

00:07:12.700 --> 00:07:16.450
So let's define a variable strength

00:07:19.440 --> 00:07:22.490
and we're going to set it to the leaf.

00:07:23.000 --> 00:07:24.960
OK.

00:07:25.470 --> 00:07:27.090
That is a strength.

00:07:27.410 --> 00:07:35.140
It's when you believe in your goal it is really important to be successful.

00:07:35.190 --> 00:07:41.930
Now the syntax for the switch is going to be the keyword switch.

00:07:42.320 --> 00:07:43.120
OK.

00:07:43.200 --> 00:07:49.270
Followed by the very well we want to check.

00:07:49.500 --> 00:07:50.680
OK.

00:07:50.870 --> 00:07:53.820
In our case its strength.

00:07:53.900 --> 00:07:59.420
I'm going to put it between penances and then after that we're going to have curly brackets.

00:08:00.000 --> 00:08:06.060
And then inside our curly brackets we're going to have all the cases possible for our variable strength

00:08:06.060 --> 00:08:06.620
.

00:08:06.690 --> 00:08:08.820
So the first case let's have

00:08:12.160 --> 00:08:13.820
belief.

00:08:14.000 --> 00:08:14.780
OK.

00:08:15.000 --> 00:08:22.790
And that's going to be followed by one on and then we say what we want to execute.

00:08:22.830 --> 00:08:28.420
If our variable strength equals belief.

00:08:28.690 --> 00:08:29.950
OK.

00:08:31.410 --> 00:08:32.290
So.

00:08:32.790 --> 00:08:38.890
So you going to echo something and then we break.

00:08:40.470 --> 00:08:41.680
OK.

00:08:41.700 --> 00:08:45.180
So break means that we're going to go out of our

00:08:50.190 --> 00:08:52.730
code inside the curly brackets.

00:08:53.190 --> 00:08:55.990
So we're just going to jump everything else.

00:08:56.040 --> 00:08:56.610
All right.

00:08:56.860 --> 00:08:58.900
So let's have another case

00:09:07.880 --> 00:09:10.810
communication.

00:09:11.020 --> 00:09:13.610
That's another good strength.

00:09:14.350 --> 00:09:15.660
OK.

00:09:15.690 --> 00:09:17.400
And here's another one

00:09:25.770 --> 00:09:28.240
petition.

00:09:29.670 --> 00:09:32.700
OK let's have another one

00:09:37.260 --> 00:09:39.780
determination.

00:09:41.730 --> 00:09:42.750
OK.

00:09:43.440 --> 00:09:44.580
And finally

00:09:48.330 --> 00:09:55.250
we're going to have the default statements and the default is going to be something.

00:09:55.440 --> 00:09:55.970
OK.

00:09:56.130 --> 00:10:02.110
So if he's not of those then we're going to excuse the default statements.

00:10:02.130 --> 00:10:07.030
And after that we break OK.

00:10:07.980 --> 00:10:11.010
So let's go back to our echo statements.

00:10:11.040 --> 00:10:18.760
So the first one is have a paragraph saying for example you have

00:10:22.170 --> 00:10:29.240
core values that's unchanging.

00:10:30.010 --> 00:10:30.890
OK.

00:10:30.930 --> 00:10:36.280
They will define your purpose in life.

00:10:37.910 --> 00:10:39.000
OK.

00:10:39.350 --> 00:10:55.190
And the second one is a program that will destroy you easily put your thoughts into words.

00:10:55.470 --> 00:10:58.370
You are a good presence.

00:11:00.000 --> 00:11:02.240
OK.

00:11:02.280 --> 00:11:14.850
And this one say you say Boga and it's right.

00:11:15.480 --> 00:11:23.860
You measure your progress against the progress of others

00:11:26.470 --> 00:11:27.640
.

00:11:28.340 --> 00:11:36.780
You try to win first place.

00:11:37.170 --> 00:11:38.460
OK.

00:11:39.530 --> 00:11:41.800
So let's get rid of this one.

00:11:42.330 --> 00:11:43.860
And the defaults let's say

00:11:50.090 --> 00:11:51.430
two is a trend

00:11:54.070 --> 00:11:59.160
you have many.

00:12:00.210 --> 00:12:00.880
OK.

00:12:01.140 --> 00:12:04.480
Now if we save and refresh the page.

00:12:05.630 --> 00:12:15.790
So since our value is belief or the strength variable we've caused this message which corresponds to

00:12:16.130 --> 00:12:16.480
this one
