00:00:01,170 --> 00:00:05,450
Hello and welcome back to the next video of this course in programming cities.

2
00:00:05,490 --> 00:00:10,010
Now in this video we will learn about the control statements in case of Cartland.

3
00:00:10,020 --> 00:00:16,050
Now there are some changes in Gears of control statements in case of Cartland such as we can use the

4
00:00:16,050 --> 00:00:21,000
if else condition as an expression an insert of switch statement.

5
00:00:21,030 --> 00:00:24,150
We have re-instatement in case of Cartland.

6
00:00:24,330 --> 00:00:29,220
So let us first check out the if else conditional statements in case of Cartland.

7
00:00:29,220 --> 00:00:34,560
Now here I have simply defined two values equal to do and be equal to 5.

8
00:00:34,560 --> 00:00:38,990
Now here I will simply define a valid max value.

9
00:00:39,210 --> 00:00:40,470
Let's see in.

10
00:00:40,810 --> 00:00:42,090
And now down the side.

11
00:00:42,090 --> 00:00:42,940
I was simply write.

12
00:00:42,990 --> 00:00:53,890
Typical if else condition if it is greater than B then simply assign max value equal to a right and

13
00:00:53,890 --> 00:01:04,190
then is max value equal to B and then finally we are simply going to print the max value right.

14
00:01:04,420 --> 00:01:06,790
Let us note in the chord.

15
00:01:07,000 --> 00:01:14,590
So here in the outbuild we get 5 so we have simply written code to find the maximum value of these two

16
00:01:14,680 --> 00:01:18,520
numbers and B right now in Cartland we have.

17
00:01:18,620 --> 00:01:20,140
If expressions.

18
00:01:20,140 --> 00:01:23,560
Now we can use the if condition as an expression.

19
00:01:23,620 --> 00:01:25,350
So how to do that.

20
00:01:25,780 --> 00:01:33,730
So in that case instead of defining the max value here what we do is simply assign it to the max value

21
00:01:33,880 --> 00:01:34,860
directly.

22
00:01:34,960 --> 00:01:38,210
And here I will simply remove it.

23
00:01:38,340 --> 00:01:43,030
The max value and now leads straight to clean up our record.

24
00:01:43,050 --> 00:01:45,600
So here what I am doing is this.

25
00:01:45,670 --> 00:01:47,310
If as an expression.

26
00:01:47,400 --> 00:01:56,040
Now if it is greater than B then simply return a and assign it to the max value variable is simply returned

27
00:01:56,070 --> 00:02:01,170
B which is the maximum value and assign it to this very bill and at the end.

28
00:02:01,170 --> 00:02:02,720
Simply put into value.

29
00:02:02,720 --> 00:02:10,700
Let us note in the chord so in the output again we get 5 so in Scotland we can make the if condition

30
00:02:10,760 --> 00:02:12,380
to return some value.

31
00:02:12,380 --> 00:02:18,800
Now suppose if I have the multiple lines of code inside the if condition so which value will be returned

32
00:02:18,890 --> 00:02:21,770
and stored to the max value variable.

33
00:02:21,770 --> 00:02:24,000
Now suppose I have a quarter block.

34
00:02:24,110 --> 00:02:25,820
So here what do I have is.

35
00:02:25,880 --> 00:02:30,860
I am having the cord block if condition here and inspired here.

36
00:02:30,980 --> 00:02:35,110
Now I suppose if I have multiple lines of code here let's see.

37
00:02:35,120 --> 00:02:44,440
Print is greater and simply copy the word from here and pasted here and here.

38
00:02:44,450 --> 00:02:47,230
Simply put in B is greater right.

39
00:02:47,390 --> 00:02:53,000
So in this situation where we have multiple lines of code within the if block and also as log.

40
00:02:53,120 --> 00:02:55,670
So which of the following will we return.

41
00:02:55,670 --> 00:02:56,840
Now as for the rule.

42
00:02:56,840 --> 00:03:01,550
The last statement that is defined inside the if condition will be returned.

43
00:03:01,700 --> 00:03:06,690
So here the last part is a and here the last piece of cord is B.

44
00:03:06,830 --> 00:03:10,770
So here it will be returned and here B will be returned.

45
00:03:11,030 --> 00:03:14,520
So this code will be executed and then it will be returned.

46
00:03:14,540 --> 00:03:18,780
And similarly this code will be executed and then B will be returned.

47
00:03:19,100 --> 00:03:21,430
And now let us run the code.

48
00:03:21,500 --> 00:03:28,590
So here we get B is greater and at last we are printing the value of max value variable right.

49
00:03:28,970 --> 00:03:34,160
So in this way we are actually using the condition as the expression.

50
00:03:34,160 --> 00:03:37,000
Now this if condition is returning some value.

51
00:03:37,130 --> 00:03:40,220
So that is why we call it if as expression.
