1
00:00:00,870 --> 00:00:09,840
In this lecture we are going to implement a very simple if statement that will clear the default zero

2
00:00:12,270 --> 00:00:12,980
at the moment.

3
00:00:12,990 --> 00:00:16,950
We've got a default zero in the result box here.

4
00:00:17,430 --> 00:00:22,380
So any of the kids will click gets added on to the zero.

5
00:00:22,410 --> 00:00:29,910
So what we're going to do in this lecture here will implement a simple if statement that will clear

6
00:00:29,910 --> 00:00:34,580
the zero when you input any of the keys to numeric keys.

7
00:00:34,590 --> 00:00:36,090
That's all right.

8
00:00:36,120 --> 00:00:38,970
So let's go ahead and start to implement that.

9
00:00:39,360 --> 00:00:48,120
So I'm going to implement that just above this button here.

10
00:00:48,120 --> 00:00:50,900
All right let's implement that somewhere here.

11
00:00:50,920 --> 00:00:52,570
Someone would say if

12
00:00:55,570 --> 00:01:04,650
if the result box which is you the result of the computed numbers.

13
00:01:04,680 --> 00:01:12,660
So when you click on the PS it displays the result box I'm going to say if the result box dot text causes

14
00:01:12,690 --> 00:01:14,790
a text so if the text from that

15
00:01:18,030 --> 00:01:25,450
is treated as equals to what you're doing when you're checking conditions you use double equals to a

16
00:01:25,470 --> 00:01:31,770
single equals two is used to assign a value double equals to compares something.

17
00:01:32,070 --> 00:01:39,090
So I'm saying in the result box of text if the text from that result box is strictly equal to zero

18
00:01:42,790 --> 00:01:45,850
need to specify what will happen then what will happen.

19
00:01:46,590 --> 00:01:47,940
I need to specify here.

20
00:01:47,960 --> 00:01:51,060
So I say is equal to zero and then the result box

21
00:01:55,640 --> 00:02:02,150
I'm attaching a dot clear method so I'm touching it Claire.

22
00:02:03,530 --> 00:02:06,100
If I scrolled through it you can see the method here.

23
00:02:06,110 --> 00:02:08,780
There is a limited set.

24
00:02:08,870 --> 00:02:15,830
So the result box dot Claire put a semicolon.

25
00:02:16,760 --> 00:02:23,710
So what is it will check if the text in the result post is strictly equal to zero.

26
00:02:23,900 --> 00:02:28,760
It will clear that just before you input a button.

27
00:02:29,260 --> 00:02:36,030
So I say that are on the code.

28
00:02:36,560 --> 00:02:37,640
We'll see what happens.

29
00:02:37,640 --> 00:02:40,920
So I expect when I click on any of the buttons.

30
00:02:40,930 --> 00:02:44,180
Now the numeric buttons the Zero should disappear.

31
00:02:44,180 --> 00:02:48,760
So for you say that 5 6.

32
00:02:49,000 --> 00:02:53,290
Not in sadness we don't get the preceding zero.

33
00:02:54,230 --> 00:03:02,000
So that's it for this lecture we've implemented a simple if statement that checks the condition to see

34
00:03:02,000 --> 00:03:09,650
if there is a text or if there is this value is present before you click on the key and it will clear

35
00:03:09,800 --> 00:03:16,980
this before you input any key using the DOT Clay method that's set for this lecture.

36
00:03:17,120 --> 00:03:18,830
Thank you so much for watching.

37
00:03:19,010 --> 00:03:19,570
Bye for now.
