00:00:00,580 --> 00:00:01,450
Welcome back.

2
00:00:01,780 --> 00:00:07,990
I want to quickly touch on the subject of what we call string concatenation.

3
00:00:08,740 --> 00:00:16,570
Yes, programmers love creating really complex names when concepts may not be as complex.

4
00:00:16,930 --> 00:00:20,140
So what does string concatenation mean?

5
00:00:20,230 --> 00:00:23,560
Well, it simply means adding strings together.

6
00:00:23,680 --> 00:00:24,910
So I can do.

7
00:00:24,940 --> 00:00:25,690
Hello?

8
00:00:26,260 --> 00:00:27,190
Plus.

9
00:00:28,580 --> 00:00:31,460
Andre and I've concatenated the string.

10
00:00:31,460 --> 00:00:34,100
I've added two strings together.

11
00:00:34,100 --> 00:00:35,840
So if I print this.

12
00:00:37,240 --> 00:00:37,720
I get.

13
00:00:37,750 --> 00:00:38,980
Hello, Andre.

14
00:00:39,670 --> 00:00:44,290
So if you ever hear people talk about String Cookout Nation, that's what they mean.

15
00:00:44,410 --> 00:00:47,440
We're concatenating strings.

16
00:00:47,530 --> 00:00:50,470
By the way, what do you think will happen if I do?

17
00:00:51,040 --> 00:00:51,880
Hello?

18
00:00:51,910 --> 00:00:52,750
Plus.

19
00:00:55,390 --> 00:00:56,710
If I click run.

20
00:00:57,310 --> 00:00:57,850
Hmm.

21
00:00:59,330 --> 00:01:00,500
That's not good, is it?

22
00:01:01,440 --> 00:01:05,730
I get type air must be string, not int.

23
00:01:06,720 --> 00:01:12,060
So it looks like string concatenation only works with strings.

24
00:01:13,090 --> 00:01:15,790
We'll explore that a little bit more in the next video.
