00:00:00,210 --> 00:00:03,810
Before we start, did you try solving the workbook yourself?

2
00:00:03,840 --> 00:00:09,600
If not, please click the link in the resources folder and follow the instructions for this workbook.

3
00:00:10,810 --> 00:00:11,200
Task.

4
00:00:11,200 --> 00:00:17,470
One is to ask the user three questions and notice that the user must submit their answer beside each

5
00:00:17,470 --> 00:00:18,130
question.

6
00:00:18,130 --> 00:00:19,990
So we will do just that.

7
00:00:20,200 --> 00:00:28,120
Over here we can say system, dot, dot, print, not print line, because we don't want to move to

8
00:00:28,120 --> 00:00:29,020
a new line.

9
00:00:29,740 --> 00:00:31,720
Pick a number to count by.

10
00:00:39,480 --> 00:00:43,050
Then we can say int step is equal to skin.

11
00:00:43,470 --> 00:00:44,490
Next int.

12
00:00:47,380 --> 00:00:47,800
All right.

13
00:00:47,800 --> 00:00:53,770
Next one is pick a number to start counting from system, dot, dot, print.

14
00:01:03,530 --> 00:01:07,280
End start is going to be equal to scandal next ent.

15
00:01:08,770 --> 00:01:11,620
And then pick a number to count to.

16
00:01:11,650 --> 00:01:16,960
So as you can see, the user is basically determining what the parameters of our loop will be.

17
00:01:19,250 --> 00:01:22,670
In this case, this one, it's going to end up determining the condition.

18
00:01:22,670 --> 00:01:27,350
So end stop is equal to skin dot next int.

19
00:01:28,710 --> 00:01:32,690
And now we can use this information to create a for loop.

20
00:01:32,700 --> 00:01:39,870
So for and I is equal to whatever the start value is, whichever number they want to start counting

21
00:01:39,870 --> 00:01:45,840
from, the loop is going to keep running so long as I is smaller than or equal to the stop.

22
00:01:47,080 --> 00:01:53,440
I hope you put smaller than or equal to not smaller then, because let's say they want to count up until

23
00:01:53,440 --> 00:01:54,070
ten.

24
00:01:54,100 --> 00:02:01,300
If you put smaller, then when I eventually does reach ten it's going to be smaller than the stop and

25
00:02:01,300 --> 00:02:02,960
the four loop is not going to run.

26
00:02:02,980 --> 00:02:06,370
Therefore, it won't print the number that you want to count to.

27
00:02:06,910 --> 00:02:09,280
So make sure you put smaller than or equal to.

28
00:02:09,310 --> 00:02:10,000
We'll break.

29
00:02:10,000 --> 00:02:11,830
Point it in just a second.

30
00:02:11,830 --> 00:02:18,880
And then every time the loop runs, we need to increase I by the number they want to count by the step.

31
00:02:18,880 --> 00:02:21,730
So I plus equal step.

32
00:02:24,030 --> 00:02:27,720
If they wanted to just count by one, then we would put in a plus plus.

33
00:02:27,720 --> 00:02:31,830
But the number we count by is determined by user input.

34
00:02:33,820 --> 00:02:40,480
And now we can just say system, dot, dot, print, not print line, because if you look back at the

35
00:02:40,480 --> 00:02:41,350
output.

36
00:02:42,400 --> 00:02:45,130
We need to print our account in a single line.

37
00:02:50,950 --> 00:02:51,790
And that is all.

38
00:02:52,180 --> 00:02:55,780
Now we can just visualize the runtime starting from here.

39
00:03:00,400 --> 00:03:03,430
The number I will count by is, let's say, two.

40
00:03:04,220 --> 00:03:08,120
The number I will start counting from, let's say, is six.

41
00:03:09,140 --> 00:03:12,020
And the number I want to count to is.

42
00:03:12,970 --> 00:03:14,590
How about 16?

43
00:03:15,860 --> 00:03:18,770
So I is going to start by equaling six.

44
00:03:18,800 --> 00:03:23,690
Six is smaller than or equal to 16, which means this four loop is going to run.

45
00:03:25,150 --> 00:03:27,610
And it's going to start by printing the number six.

46
00:03:28,000 --> 00:03:28,690
Beautiful.

47
00:03:28,690 --> 00:03:35,360
And once we get to here, I plus equal step is going to update the value on the left eye by two.

48
00:03:35,380 --> 00:03:37,600
So now I is going to equal eight.

49
00:03:39,080 --> 00:03:39,740
Ten.

50
00:03:40,540 --> 00:03:41,620
12.

51
00:03:42,240 --> 00:03:43,200
14.

52
00:03:44,390 --> 00:03:50,180
Once we get to here, 14 plus equal two is 16, which means this is going to run.

53
00:03:51,330 --> 00:03:55,110
Printing six up until 16 and check it out.

54
00:03:55,110 --> 00:03:58,380
We were able to start counting from six.

55
00:03:58,380 --> 00:04:02,670
We counted up until 16 and steps of two.

56
00:04:02,670 --> 00:04:06,900
And once you go back, 16 plus equal to is going to be 18.

57
00:04:06,900 --> 00:04:14,100
18 is not smaller than or equal to 16, which means this loop is going to break and your runtime will

58
00:04:14,100 --> 00:04:14,730
end.
