00:00:01,410 --> 00:00:02,040
Hello.

2
00:00:02,040 --> 00:00:09,990
In this lecture you will learn about the character types, the character types here, the store, human

3
00:00:09,990 --> 00:00:11,370
language data.

4
00:00:12,090 --> 00:00:14,580
There are six character types.

5
00:00:15,210 --> 00:00:22,680
The six are car, car, character, 16 T character and 32 T sine car.

6
00:00:22,950 --> 00:00:24,150
Unsigned character.

7
00:00:24,150 --> 00:00:25,080
We.

8
00:00:25,380 --> 00:00:26,490
Character T.

9
00:00:26,640 --> 00:00:30,030
So the character type is a default type.

10
00:00:30,300 --> 00:00:33,690
It has it always has.

11
00:00:33,690 --> 00:00:37,820
A one byte could be signed or unsigned.

12
00:00:37,830 --> 00:00:42,840
For example, this character type uses in ASCII system.

13
00:00:43,440 --> 00:00:45,990
Here we have character 16 T.

14
00:00:46,530 --> 00:00:57,150
This is the use for for two byte character sets, example UTF 16 and character 32 byte here used for

15
00:00:57,150 --> 00:00:59,190
the four byte.

16
00:00:59,460 --> 00:01:04,290
Sorry for this mistake used for four byte character sets.

17
00:01:04,290 --> 00:01:13,390
For example, this character type used on UTF two or UTF 32 character system.

18
00:01:13,390 --> 00:01:22,570
So the sign character same as character, but guaranteed to be signed, unsigned character as same as

19
00:01:22,570 --> 00:01:25,450
character, but guaranteed to be unsigned.

20
00:01:25,450 --> 00:01:33,910
And lastly, we character T has a large enough to contain the largest character of the implementations

21
00:01:33,910 --> 00:01:37,450
local which called Unicode.

22
00:01:38,080 --> 00:01:42,250
So we have two types of characters, mainly two groups of characters.

23
00:01:42,370 --> 00:01:45,400
These are the narrow characters and white characters.

24
00:01:45,430 --> 00:01:52,180
Narrow characters include characters, signed character, unsigned character, and the white characters

25
00:01:52,180 --> 00:02:04,960
includes car 16, T, car 32, T and W character T Here the the characters types here.

26
00:02:04,960 --> 00:02:16,900
As you can see here, all of that is character types and this is these are the for the types that store

27
00:02:16,900 --> 00:02:23,680
human language data for example A, B, C, D or like that.

28
00:02:24,070 --> 00:02:27,880
So we let's go to character literals.

29
00:02:27,880 --> 00:02:37,450
We will use here A character letter is a single constant character here, single quotation mark like

30
00:02:37,450 --> 00:02:38,020
this.

31
00:02:38,170 --> 00:02:46,060
So all characters, if the character is any type but character car, you must also provide a prefix

32
00:02:46,060 --> 00:03:03,250
for L for car u for car 16 T and and uppercase U for character 32 T So let me actually add this here.

33
00:03:03,880 --> 00:03:04,210
Um.

34
00:03:06,050 --> 00:03:06,710
Literal.

35
00:03:07,040 --> 00:03:13,970
Literal is character to literal is uppercase u.

36
00:03:13,970 --> 00:03:20,810
As I said, character 16 T is under case.

37
00:03:21,290 --> 00:03:23,390
Literal is just u.

38
00:03:24,510 --> 00:03:28,800
But not uppercase and the usual character.

39
00:03:30,310 --> 00:03:33,740
Has, for example, the has.

40
00:03:33,950 --> 00:03:34,280
L.

41
00:03:44,120 --> 00:03:45,530
Here, as you can see here.

42
00:03:46,850 --> 00:03:52,430
But for the default character, you just use the two quotation marks.

43
00:03:52,430 --> 00:03:56,000
And between this or be here.

44
00:03:56,000 --> 00:03:58,190
You here.

45
00:03:59,880 --> 00:04:04,620
So we have the escape sequences for characters as well.

46
00:04:06,640 --> 00:04:08,680
The escape sequence.

47
00:04:08,920 --> 00:04:11,260
Some characters don't display on the screen.

48
00:04:11,260 --> 00:04:19,240
Instead, they force the display to do things like move the cursor to the left side of the screen carriage,

49
00:04:19,240 --> 00:04:23,560
return or move the cursor down one line.

50
00:04:23,590 --> 00:04:27,910
The new line here so other characters can display on the screen.

51
00:04:27,910 --> 00:04:34,300
But they are part of the cplusplus language syntax, such as simple or double quotes you, so you must

52
00:04:34,300 --> 00:04:35,560
use them very carefully.

53
00:04:35,560 --> 00:04:41,620
But these characters into car, you use the escape sequences.

54
00:04:41,620 --> 00:04:46,690
So let's, let's create a list of the escape sequences here in this lecture.

55
00:04:47,020 --> 00:04:50,380
The first escape sequences here.

56
00:04:50,750 --> 00:04:53,440
Escape sequences.

57
00:04:56,310 --> 00:04:57,500
New line is.

58
00:04:57,510 --> 00:04:58,950
New line is.

59
00:05:00,180 --> 00:05:00,810
An.

60
00:05:03,140 --> 00:05:06,070
Uh, the top here is.

61
00:05:08,330 --> 00:05:08,870
He.

62
00:05:12,120 --> 00:05:12,660
Here.

63
00:05:13,620 --> 00:05:17,320
Tab vertical is V.

64
00:05:21,820 --> 00:05:23,830
The backspace.

65
00:05:25,640 --> 00:05:28,760
Back space is be.

66
00:05:30,050 --> 00:05:30,600
Of ski.

67
00:05:32,180 --> 00:05:34,100
The carriage.

68
00:05:35,040 --> 00:05:35,970
Return of.

69
00:05:39,730 --> 00:05:40,120
P.

70
00:05:41,870 --> 00:05:43,220
The carriage return.

71
00:05:44,670 --> 00:05:47,250
Is re are.

72
00:05:49,910 --> 00:05:51,230
For form fit.

73
00:05:51,260 --> 00:05:54,580
Form fit is f.

74
00:05:57,140 --> 00:06:01,080
The alert alert is E.

75
00:06:03,580 --> 00:06:04,720
The backslash.

76
00:06:09,680 --> 00:06:11,900
Is double here.

77
00:06:12,170 --> 00:06:14,270
Double X character.

78
00:06:14,630 --> 00:06:19,310
The single quote is this.

79
00:06:19,940 --> 00:06:21,140
And double quote.

80
00:06:23,780 --> 00:06:27,590
Is this double quote just a normal double quote.

81
00:06:30,060 --> 00:06:33,210
And the null character here, the null.

82
00:06:34,870 --> 00:06:38,110
Car is zero backslash.

83
00:06:38,110 --> 00:06:38,770
Zero.

84
00:06:39,770 --> 00:06:42,860
So we have a Unicode escape characters as well.

85
00:06:42,860 --> 00:06:49,070
So you can specify Unicode character, Unicode characters, literals using the universal character names

86
00:06:50,210 --> 00:06:58,700
and you can form a universal character name in one of the two ways the prefix you here you.

87
00:07:00,100 --> 00:07:12,880
Uh, followed by the four digit of Unicode point here or the prefix uppercase U followed by an eight

88
00:07:12,880 --> 00:07:15,550
digit Unicode code point.

89
00:07:15,550 --> 00:07:19,570
So you can represent a E character here.

90
00:07:21,190 --> 00:07:25,510
E character is here.

91
00:07:29,780 --> 00:07:33,980
A lowercase u and four digit.

92
00:07:34,520 --> 00:07:34,870
So.

93
00:07:34,910 --> 00:07:37,070
So a character is this.

94
00:07:39,060 --> 00:07:50,310
So actually you can learn this character on um the so there's a list for this character Unicode characters

95
00:07:50,310 --> 00:07:55,620
here you need Unicode characters.

96
00:07:56,860 --> 00:07:57,280
Here.

97
00:08:03,420 --> 00:08:05,310
Uh, table.

98
00:08:25,760 --> 00:08:36,830
Here I found this website which is almost all Unicode characters and their, um, their Unicode point

99
00:08:36,830 --> 00:08:41,040
character and UTF eight points here.

100
00:08:41,060 --> 00:08:46,580
So as you can see here, if you want to write an A to console.

101
00:08:47,770 --> 00:09:00,320
Uh, you can just use this with single quotes followed by the backslash U and after that you enter the

102
00:09:00,320 --> 00:09:02,290
code of this characters.

103
00:09:03,180 --> 00:09:11,340
So as you can see, you can use the other symbols and characters here with different numbers.

104
00:09:13,460 --> 00:09:13,940
Here.

105
00:09:15,690 --> 00:09:18,120
So I will copy this website.

106
00:09:20,250 --> 00:09:26,970
Uh, on the lectures download here, which you can see it here.

107
00:09:27,120 --> 00:09:28,200
So.

108
00:09:29,990 --> 00:09:32,410
Let's begin with an example.

109
00:09:32,420 --> 00:09:34,010
Enough for the terrorists here.

110
00:09:34,010 --> 00:09:35,870
Let's get to practical.

111
00:09:35,870 --> 00:09:39,530
So let's create our code here.

112
00:09:41,180 --> 00:09:47,770
Let's create some character named X and give this M and let's create another character.

113
00:09:47,780 --> 00:09:48,980
Double character.

114
00:09:50,270 --> 00:09:53,560
He called ye here.

115
00:09:53,940 --> 00:09:59,390
Why the big uppercase L and Z here?

116
00:10:03,420 --> 00:10:05,790
And then print f.

117
00:10:08,960 --> 00:10:23,000
Windows binaries start with C and C again and new line and gave this format specifiers as first our

118
00:10:23,000 --> 00:10:24,140
x and y.

119
00:10:25,270 --> 00:10:25,660
Here.

120
00:10:29,910 --> 00:10:34,740
Uh, I thought we did hear something or see.

121
00:10:34,770 --> 00:10:35,430
No.

122
00:10:35,580 --> 00:10:39,600
So we gave this X and Y.

123
00:10:41,990 --> 00:10:42,640
Yeah.

124
00:10:42,650 --> 00:10:43,400
Sorry.

125
00:10:47,990 --> 00:10:51,080
Well, let's compile this code now.

126
00:10:52,490 --> 00:10:52,790
Oops.

127
00:10:58,050 --> 00:10:58,500
Run.

128
00:11:03,680 --> 00:11:08,930
Here a Windows binaries start with M.

129
00:11:09,990 --> 00:11:10,520
And Z.

130
00:11:11,100 --> 00:11:14,690
This program outputs this year.

131
00:11:15,840 --> 00:11:27,270
As you can see here, even though the M is a narrow character car and then the Z is here is a wide character.

132
00:11:27,940 --> 00:11:35,620
Printf works because the program uses the correct format specifiers.

133
00:11:35,800 --> 00:11:42,070
The next lecture will be about the boolean types, so I'm waiting you in the next lecture.
