1
00:00:00,810 --> 00:00:03,540
C plus plus support jumps.

2
00:00:03,540 --> 00:00:06,630
And in most cases there are better ways to branch code.

3
00:00:06,660 --> 00:00:10,680
However, for completeness, we will cover the mechanism here.

4
00:00:10,710 --> 00:00:18,000
There are two parts to a jump, a labeled statement to jump and the to go to statement.

5
00:00:18,030 --> 00:00:24,300
A label has the same naming rules as a variable and it's declared suffixed with a colon.

6
00:00:24,300 --> 00:00:27,070
And it must be before statement here.

7
00:00:27,090 --> 00:00:30,480
The Goto statement is called using the labels name here.

8
00:00:30,720 --> 00:00:34,530
Let's make it the another for loop here for integer.

9
00:00:36,330 --> 00:00:41,430
Or integer zero while is less than ten.

10
00:00:43,220 --> 00:00:50,250
Lower integer zero while is less than ten and increment by one.

11
00:00:50,270 --> 00:00:57,560
Here and std std see out or make it see out here.

12
00:00:57,590 --> 00:01:01,580
See out e here and inline here.

13
00:01:01,910 --> 00:01:11,030
And if e equals five then go to end here and.

14
00:01:11,910 --> 00:01:12,390
Here.

15
00:01:12,420 --> 00:01:14,880
Actually, we don't, uh, need.

16
00:01:15,270 --> 00:01:17,310
We have to declare the end here as well.

17
00:01:17,310 --> 00:01:20,820
If we make it go to here and here.

18
00:01:23,410 --> 00:01:26,200
Outside the loop here in the main function.

19
00:01:26,200 --> 00:01:27,130
And.

20
00:01:27,610 --> 00:01:28,990
And STD.

21
00:01:29,710 --> 00:01:30,160
STD.

22
00:01:34,090 --> 00:01:35,620
Arrested or out.

23
00:01:37,240 --> 00:01:38,500
And here.

24
00:01:43,160 --> 00:01:47,580
So the label must be in the same function as the calling go through here.

25
00:01:47,600 --> 00:01:51,020
So let's make it run.

26
00:01:51,020 --> 00:02:01,190
And as you can see here, if condition is executed and we made it with go to keyword and executed the

27
00:02:01,220 --> 00:02:02,060
end here.

28
00:02:02,060 --> 00:02:07,280
So the label must be in the same function as the calling go through here, as I said earlier.

29
00:02:07,280 --> 00:02:13,430
But the jumps are rarely used because they encourage you to write non structured code.

30
00:02:13,460 --> 00:02:19,730
However, if you have a routine with the loops or if statements, it might make more sense and more

31
00:02:19,730 --> 00:02:25,160
readable to use a goto to jump to clean up code here.
