1
00:00:00,180 --> 00:00:00,600
Okay.

2
00:00:00,600 --> 00:00:02,340
So you made it to the end, hopefully.

3
00:00:02,340 --> 00:00:06,330
I mean, I guess you could have skipped forward, but you made it to this video however you got here

4
00:00:06,750 --> 00:00:09,030
at the end of the string function section.

5
00:00:09,210 --> 00:00:15,510
So we have a couple of exercises and they range from pretty straightforward to reasonably complex where

6
00:00:15,510 --> 00:00:18,030
we combine multiple string functions together.

7
00:00:18,090 --> 00:00:19,410
So let's get started.

8
00:00:20,100 --> 00:00:27,090
The first one here is to reverse and uppercase the following sentence Why does my cat look at me with

9
00:00:27,090 --> 00:00:28,200
such hatred?

10
00:00:29,970 --> 00:00:33,450
I would also appreciate an answer to that if anyone can help me.

11
00:00:34,020 --> 00:00:36,630
But anyways, what we need to do is just take this.

12
00:00:36,630 --> 00:00:40,740
You can copy it or type it out and just use my as well.

13
00:00:40,740 --> 00:00:44,700
I should specify, don't just manually reverse it and type it uppercase.

14
00:00:44,700 --> 00:00:48,720
I mean, using what you just learned, how can you reverse an uppercase this.

15
00:00:49,590 --> 00:00:54,990
All right then when you're done with that, the next problem, this one is a little different.

16
00:00:54,990 --> 00:00:57,930
You don't have to actually do anything I want you to do.

17
00:00:57,930 --> 00:00:59,910
Figure out what this prints out.

18
00:01:00,660 --> 00:01:03,630
So don't just cheat and copy and paste it.

19
00:01:03,660 --> 00:01:08,340
You can do that to check your work, of course, but try and work through what's actually happening.

20
00:01:08,340 --> 00:01:14,190
We've got to select, we've got to replace and it can cat and some words and spaces and symbols and

21
00:01:14,190 --> 00:01:14,880
dashes.

22
00:01:15,270 --> 00:01:23,490
So give it a shot, then move on to the next one here, which is to replace all the spaces in book titles.

23
00:01:23,640 --> 00:01:29,460
With this little arrow, it's a dash greater than sign, so replace every space.

24
00:01:29,460 --> 00:01:35,130
So instead of the space namesake, it's the dash, or let's just say arrow the arrow namesake.

25
00:01:35,130 --> 00:01:37,650
And that happens for every space.

26
00:01:38,820 --> 00:01:42,630
And one more thing I'll call attention to is up here, it just says title.

27
00:01:43,230 --> 00:01:47,190
So you're going to need to use as to make sure it says title.

28
00:01:47,280 --> 00:01:53,580
So basically your task is to just get this same data printed out, this exact same format.

29
00:01:54,510 --> 00:01:57,480
Then after that, print this out.

30
00:01:58,110 --> 00:02:06,750
So you're going to have the author's last name printed regularly forwards, and then next to it you'll

31
00:02:06,750 --> 00:02:12,420
have the same author's name printed backwards, in reverse, you might say.

32
00:02:12,900 --> 00:02:14,400
So that's what you need to do.

33
00:02:14,760 --> 00:02:16,050
Also, pay attention up here.

34
00:02:16,050 --> 00:02:19,920
It says forwards and backwards, so you'll need to use as again to do that.

35
00:02:20,550 --> 00:02:27,480
Then once you do that, the next one like you to print out a full author's name.

36
00:02:27,660 --> 00:02:30,600
So it's a little more complicated in caps.

37
00:02:30,810 --> 00:02:32,940
So we want Jhumpa Lahiri.

38
00:02:32,940 --> 00:02:39,330
So that's author first name and last name combined and uppercase, and that should happen for every

39
00:02:39,330 --> 00:02:39,990
author.

40
00:02:40,230 --> 00:02:45,840
And then also again, the name appears or the header says full name in caps.

41
00:02:46,800 --> 00:02:50,250
All right, then make this happen.

42
00:02:50,520 --> 00:02:59,970
So what this is showing is a title The Namesake and then was released in and then the actual date that

43
00:02:59,970 --> 00:03:02,370
we have stored in our database for when it was released.

44
00:03:02,760 --> 00:03:10,350
So you need to combine a title was released in and then the year it was released and again I called

45
00:03:10,350 --> 00:03:13,350
it Blurb but just put some label up there.

46
00:03:14,710 --> 00:03:22,210
Then next one here, print book titles and the length of each title, which is pretty similar to what

47
00:03:22,210 --> 00:03:25,390
I had, what I did using authors last names.

48
00:03:25,390 --> 00:03:30,440
So just print the title and then the number of characters in that title.

49
00:03:30,460 --> 00:03:32,200
As you can see, some of them are quite long.

50
00:03:33,190 --> 00:03:36,640
The only other thing I would say is up here I pay attention.

51
00:03:36,640 --> 00:03:40,870
We have character count, so use as you get it by now.

52
00:03:42,070 --> 00:03:46,630
Then finally, this one combines three different pieces of data.

53
00:03:47,180 --> 00:03:49,090
We'd like to have a shortened title.

54
00:03:50,230 --> 00:03:52,000
So I believe this is ten characters.

55
00:03:52,000 --> 00:03:54,940
One, two, three, four, five, six, seven, eight, nine.

56
00:03:54,940 --> 00:03:55,270
Yes.

57
00:03:55,270 --> 00:04:04,540
So the first ten characters and then a dot, dot, dot afterwards and call that short title, then we'll

58
00:04:04,540 --> 00:04:05,800
have the author print it out.

59
00:04:05,800 --> 00:04:08,500
But the way it should be printed is last name.

60
00:04:08,500 --> 00:04:11,590
Followed by a comma, followed by first name.

61
00:04:13,200 --> 00:04:15,300
And then quantity.

62
00:04:15,570 --> 00:04:22,260
So quantity should not just be the number we have in stock, but it should be the sentence 12 in stock

63
00:04:22,260 --> 00:04:23,760
or 104 in stock.

64
00:04:23,940 --> 00:04:30,630
So there's a lot of pieces here, and each one of these three is going to require multiple string functions

65
00:04:30,630 --> 00:04:31,560
to make it work.

66
00:04:32,250 --> 00:04:33,540
So give it a shot.

67
00:04:34,170 --> 00:04:35,820
This one is a little more challenging.

68
00:04:35,820 --> 00:04:39,720
So don't panic again if you don't get it, but try them all out.

69
00:04:39,720 --> 00:04:42,270
And then in the next video we'll have solutions.
