1
00:00:00,360 --> 00:00:02,520
OK, so we're done with the second chapter.

2
00:00:02,550 --> 00:00:08,700
Now, you've seen the first two fundamentals of the cutline programming language, and we, of course,

3
00:00:08,700 --> 00:00:14,370
have a bunch more fundamentals to learn object oriented programming, but on more advanced stuff as

4
00:00:14,370 --> 00:00:14,730
well.

5
00:00:14,970 --> 00:00:19,120
So in this chapter, what we have looked at are variables.

6
00:00:19,230 --> 00:00:21,290
So how we can store data.

7
00:00:21,480 --> 00:00:25,740
Then we saw that there are different data types that we need to be careful with.

8
00:00:26,020 --> 00:00:33,180
Then we looked at his statements and when statement, so code that will only be executed if a specific

9
00:00:33,180 --> 00:00:35,870
condition is met and then also loops.

10
00:00:35,870 --> 00:00:41,760
So code that will be rerun multiple times depending on conditions and also on how many times he wanted

11
00:00:41,760 --> 00:00:47,960
to run or maybe even how many times it's supposed to run based on values that it has based on its state.

12
00:00:48,240 --> 00:00:55,140
And then we looked at functions which allow us to sum up code to be reused.

13
00:00:55,350 --> 00:01:01,590
And this is super important and useful and that will come in even more useful when we get back to object

14
00:01:01,590 --> 00:01:02,430
oriented programming.

15
00:01:02,730 --> 00:01:03,060
All right.

16
00:01:03,060 --> 00:01:05,220
So then we also looked at Nullable.

17
00:01:05,430 --> 00:01:13,140
So how to use variables which have a null value, which are pretty much empty, and what you need to

18
00:01:13,140 --> 00:01:14,460
consider when using them.

19
00:01:14,970 --> 00:01:15,300
All right.

20
00:01:15,310 --> 00:01:16,760
So that's it for this chapter.

21
00:01:16,920 --> 00:01:20,730
I hope you also ran through the exercises and you finished them.

22
00:01:20,940 --> 00:01:27,400
And yeah, let's get right into the next chapter where we're going to look at object oriented programming.

23
00:01:27,570 --> 00:01:28,070
All right.

24
00:01:28,130 --> 00:01:29,340
I'll see you in the next chapter.
