1
00:00:05,330 --> 00:00:10,910
Now that code light is installed, we need to run it, configure it, and then run a little test program

2
00:00:10,910 --> 00:00:13,000
to make sure our configuration is correct.

3
00:00:13,010 --> 00:00:17,810
So the first thing we want to do is we want to find code light and you can just type code in the search

4
00:00:17,810 --> 00:00:20,180
and you'll find code light and double click.

5
00:00:22,130 --> 00:00:26,390
Now the first time it runs, you make it a small window like this and it's probably a good idea just

6
00:00:26,390 --> 00:00:27,650
to make it a little larger.

7
00:00:29,240 --> 00:00:33,590
Now, sometimes when you run it the first time, you'll get a setup wizard that runs.

8
00:00:33,590 --> 00:00:34,640
Sometimes you don't.

9
00:00:34,640 --> 00:00:41,060
We'd like to run the setup wizard, so if it doesn't show up, you can go to help run the setup wizard

10
00:00:41,060 --> 00:00:44,960
and select that and you get a window that pops up.

11
00:00:45,110 --> 00:00:46,640
So I'll select next.

12
00:00:47,660 --> 00:00:53,270
Now here, code light supports PHP and Node and a few other technologies.

13
00:00:53,270 --> 00:00:55,520
We really don't want all that clutter on our IDE.

14
00:00:55,550 --> 00:00:58,130
We want to strictly concentrate on C++.

15
00:00:58,130 --> 00:01:04,370
So I would suggest that we clear all the plug ins and then turn on only the C++ plug ins.

16
00:01:04,370 --> 00:01:10,160
So you can see now that not everything is checked, only the C++ plug ins are checked and we'll select

17
00:01:10,160 --> 00:01:10,790
next.

18
00:01:11,810 --> 00:01:15,350
Now we'll scan our computer for any installed compilers.

19
00:01:15,350 --> 00:01:19,520
So we'll scan the computer and it's found GCC and cross GCC.

20
00:01:19,520 --> 00:01:20,990
I'm going to select GCC.

21
00:01:21,020 --> 00:01:28,190
JC stands for the new compiler collection, which includes C, C++, Fortran, Ada and a few others

22
00:01:28,640 --> 00:01:29,840
I'll select next.

23
00:01:31,670 --> 00:01:35,360
As far as the editor theme, this is really a preference for you.

24
00:01:35,750 --> 00:01:40,580
This Dark Monaco theme is really easy on the eyes, but it doesn't show up too well on video.

25
00:01:40,580 --> 00:01:45,380
So I'm going to select the classic eclipse, look for the videos.

26
00:01:45,380 --> 00:01:47,090
You can choose whatever your preference is.

27
00:01:47,090 --> 00:01:48,170
Now press next.

28
00:01:49,550 --> 00:01:53,390
I'll leave these defaults as is and press finish.

29
00:01:57,110 --> 00:01:59,810
Now sometimes it opens up to windows like you see here.

30
00:01:59,810 --> 00:02:06,710
So I want to save an exit and I want to shut down all the versions that I've got going.

31
00:02:06,710 --> 00:02:10,669
I don't know why it does this, but it does it a few times and I'll save an exit again.

32
00:02:11,570 --> 00:02:13,460
All right, so now let's now we're back to normal.

33
00:02:13,460 --> 00:02:14,390
Let's try that again.

34
00:02:14,390 --> 00:02:15,740
So we'll run code light

35
00:02:19,010 --> 00:02:22,100
and let's make this full screen again.

36
00:02:22,550 --> 00:02:23,300
Perfect.

37
00:02:24,170 --> 00:02:26,960
So now what we need to do is we need to create a workspace.

38
00:02:26,990 --> 00:02:33,770
A workspace is an area where we can have our C++ projects, so we can have many C++ projects in one

39
00:02:33,770 --> 00:02:34,640
workspace.

40
00:02:34,640 --> 00:02:38,780
We can do that by selecting this button here called new workspace.

41
00:02:38,780 --> 00:02:44,360
Or we can go up to file new new workspace either place.

42
00:02:44,360 --> 00:02:48,830
So I'm going to select this button here and it's going to ask you for the workspace name.

43
00:02:48,830 --> 00:02:50,270
This can be any name you like.

44
00:02:50,300 --> 00:02:57,830
I'm going to say C.P Workspace and I'm going to put this on my desktop.

45
00:02:57,830 --> 00:03:00,440
You can store it anywhere you like as long as you remember where it's at.

46
00:03:00,560 --> 00:03:02,510
So I'm going to put this on my desktop.

47
00:03:07,040 --> 00:03:12,170
I want to create the workspace under a separate directory that'll help me organize my files better and

48
00:03:12,170 --> 00:03:12,440
press.

49
00:03:12,440 --> 00:03:14,690
Okay, that's it.

50
00:03:14,690 --> 00:03:17,930
Now we've got a workspace which you can see here on the left side.

51
00:03:18,140 --> 00:03:23,870
I can right click on that now and create a new project again.

52
00:03:23,870 --> 00:03:28,880
I can also go up file new project, so I'll do that.

53
00:03:29,660 --> 00:03:33,860
Now we've got some options here as to which template to use to create the project.

54
00:03:33,860 --> 00:03:40,130
We're going to stick to the console template, which is just basically a terminal window and we want

55
00:03:40,160 --> 00:03:41,030
G plus plus.

56
00:03:41,030 --> 00:03:42,920
That's the C plus plus compiler.

57
00:03:43,010 --> 00:03:46,700
It's called G Plus Plus because it's the new C++ compiler.

58
00:03:47,060 --> 00:03:48,260
I'll select next.

59
00:03:49,940 --> 00:03:51,590
What's my project name?

60
00:03:51,590 --> 00:03:53,120
It could be anything you like.

61
00:03:53,750 --> 00:03:55,940
Don't use spaces for any of these project names.

62
00:03:55,940 --> 00:03:57,290
So I'll just say test one.

63
00:03:59,660 --> 00:04:04,310
And again, I want to create a project in a separate directory under the workspace, so I'll select

64
00:04:04,310 --> 00:04:04,970
next.

65
00:04:06,110 --> 00:04:08,390
Now it's going to ask you which compiler do you want to use?

66
00:04:08,390 --> 00:04:10,850
You may have a lot of different compilers on your system.

67
00:04:11,240 --> 00:04:15,050
Just select the one that you used in the setup wizard and you'll be fine.

68
00:04:15,050 --> 00:04:17,089
And these defaults are perfectly fine.

69
00:04:17,089 --> 00:04:24,890
We'll select finish and that creates a test project under the CP workspace and you can see it's called

70
00:04:24,890 --> 00:04:31,490
it's created a source directory and in there it's got a main CP file that's our C++ source code and

71
00:04:31,490 --> 00:04:32,720
we'll get to that in a second.

72
00:04:33,590 --> 00:04:37,850
We need to do a couple of bits of configuration though before we do anything else.

73
00:04:38,600 --> 00:04:44,450
Let's go to our project test one in this case and we'll right click and we'll go down to the bottom

74
00:04:44,450 --> 00:04:49,850
where it says settings and we'll select that and then we'll go to where it says compiler options.

75
00:04:50,540 --> 00:04:53,180
And notice, I mean, the global settings, that's pretty important.

76
00:04:53,180 --> 00:04:58,070
I mean the global settings compiler options and then I'll select these three little dots here on the

77
00:04:58,070 --> 00:05:02,270
button and I want to make sure that w all is selected.

78
00:05:02,270 --> 00:05:03,650
That way we always get warning.

79
00:05:04,410 --> 00:05:09,590
And I want to make sure that the C++ standard, C++ 14 is selected.

80
00:05:09,600 --> 00:05:15,210
That's the latest standard for C++ that will make sure that we're using the modern C++ compiler.

81
00:05:15,870 --> 00:05:19,070
At that point, you can click Apply.

82
00:05:19,570 --> 00:05:21,960
Okay, good.

83
00:05:21,960 --> 00:05:29,910
Now we can go to our workspace and right click on that and come down to workspace settings and you'll

84
00:05:29,910 --> 00:05:31,980
see environment and code completion.

85
00:05:31,980 --> 00:05:36,060
Go to the code completion and select Enable C++ 14 Standard.

86
00:05:36,840 --> 00:05:42,570
The code completion is a tool that the Integrated Development Environment uses that tries to figure

87
00:05:42,570 --> 00:05:47,640
out what I'm typing and what I want to type, and it helps predict what I want to do so it can help

88
00:05:47,640 --> 00:05:51,120
me so I don't have to type so much and it can do some checking as it goes.

89
00:05:51,420 --> 00:05:56,010
In this case, I'm just telling you to use the modern C++ compiler I'll select.

90
00:05:56,010 --> 00:05:56,640
Okay.

91
00:05:57,960 --> 00:05:58,740
And that's it.

92
00:05:58,740 --> 00:06:00,960
Now we can run a simple test program.

93
00:06:00,960 --> 00:06:07,170
We'll double click the main CPP file, and this is actually C code, not C++ code.

94
00:06:07,170 --> 00:06:10,320
So we'll delete this in a minute, but that font is a little small.

95
00:06:10,320 --> 00:06:17,070
So in my case, since I'm doing this on video, I'm going to go to settings, colors and fonts, and

96
00:06:17,070 --> 00:06:19,290
I'm just going to set that to about 16.

97
00:06:21,870 --> 00:06:23,190
And let's see,

98
00:06:29,550 --> 00:06:30,330
that's much better.

99
00:06:30,330 --> 00:06:31,650
You should see that much better.

100
00:06:33,360 --> 00:06:41,160
So let's delete all of this and we'll write a really simple C++ program as we go through the course.

101
00:06:41,160 --> 00:06:46,140
I'll talk about the anatomy of a C++ program and we'll go into detail as to what everything I'm going

102
00:06:46,140 --> 00:06:47,310
to be typing here means.

103
00:06:47,310 --> 00:06:52,470
But for now, just type along and let's get a clean run so that we know our environments are set up.

104
00:06:52,470 --> 00:06:58,860
So the first thing we want to write is we want to write, pound, include and IO stream inside angle

105
00:06:58,860 --> 00:07:09,060
brackets, then we'll press enter, then we'll say int main and open and closed parens, then we'll

106
00:07:09,060 --> 00:07:15,150
create, then we'll type left curly and the integrated development environment will automatically close

107
00:07:15,150 --> 00:07:15,900
that for me.

108
00:07:16,770 --> 00:07:25,290
And here all I want to do is say STD to colons and see out then the insertion operator, which is two

109
00:07:25,290 --> 00:07:33,300
less than sines with no space in between and just some strings saying hello, testing or anything else

110
00:07:33,300 --> 00:07:33,840
you like.

111
00:07:34,410 --> 00:07:36,150
That has to be in double quotes.

112
00:07:36,450 --> 00:07:39,870
And then finally we'll put a semicolon on the end of that to terminate.

113
00:07:40,650 --> 00:07:43,770
And then finally the last statement will be returned zero.

114
00:07:44,010 --> 00:07:46,350
That means that the program terminated correctly.

115
00:07:46,350 --> 00:07:47,040
That's it.

116
00:07:47,040 --> 00:07:50,340
That's our first really simple C++ program.

117
00:07:50,340 --> 00:07:54,690
And like I said in the beginning of the course, I'll go through what all of this means and we'll go

118
00:07:54,690 --> 00:07:58,050
through the anatomy of a C++ program in great detail.

119
00:07:58,530 --> 00:07:59,670
I'll save this.

120
00:08:00,720 --> 00:08:06,720
Another option you may like is if you come up here to the menu and you say view and it will say Toggle

121
00:08:06,720 --> 00:08:10,920
minimal view and you can see it's putting a bunch of buttons up here.

122
00:08:10,920 --> 00:08:16,110
If you like this, this is great because you can run and compile and do all kinds of things just by

123
00:08:16,110 --> 00:08:17,160
clicking on a button.

124
00:08:17,400 --> 00:08:21,240
I'm not going to use that because I find that it's pretty distracting to the video.

125
00:08:21,240 --> 00:08:25,800
So what I'm going to do is I'm just going to shut that off on my end, but feel free to use it.

126
00:08:25,950 --> 00:08:30,270
I'm going to use command keys and I'll also just come up here and say, build.

127
00:08:30,270 --> 00:08:33,750
And that way it's very explicit what I'm doing rather than just clicking on a button.

128
00:08:34,950 --> 00:08:35,700
So that's it.

129
00:08:35,700 --> 00:08:36,539
So let's run this.

130
00:08:36,539 --> 00:08:39,179
Now what I'll do is I'll say Build.

131
00:08:39,179 --> 00:08:41,640
First thing I want to do is I want to clean this project.

132
00:08:41,640 --> 00:08:44,130
That way there's no remnants of anything left over.

133
00:08:44,130 --> 00:08:45,870
It'll put it into a stable state.

134
00:08:45,870 --> 00:08:46,770
That's good to go.

135
00:08:46,770 --> 00:08:48,120
So I'll clean the project.

136
00:08:48,960 --> 00:08:49,410
All the.

137
00:08:49,410 --> 00:08:51,630
Any messages will show up down here.

138
00:08:51,840 --> 00:08:53,400
Then I'll say, build.

139
00:08:53,580 --> 00:08:54,660
Now I'll just say run.

140
00:08:55,080 --> 00:08:58,620
And it's going to ask me, do I just want to run it or do I want to build it and run it?

141
00:08:58,620 --> 00:09:01,650
Well, in this case, I have to build it and run it because I haven't built it yet.

142
00:09:01,650 --> 00:09:03,780
So I'll select, build and execute.

143
00:09:05,580 --> 00:09:11,370
And if all goes well, we'll get a window that pops up that says Hello, testing exactly what we typed

144
00:09:11,370 --> 00:09:11,850
here.

145
00:09:12,390 --> 00:09:13,710
Press any key to continue.

146
00:09:13,710 --> 00:09:15,120
Oh, sorry, press enter to continue.

147
00:09:15,120 --> 00:09:16,920
Which I'm going to press now.

148
00:09:16,920 --> 00:09:19,560
The window goes away and we're done now.

149
00:09:19,560 --> 00:09:21,450
Several things could go wrong here.

150
00:09:21,450 --> 00:09:23,400
You may have an error in your program.

151
00:09:23,400 --> 00:09:24,810
You might have forgotten to type this.

152
00:09:24,810 --> 00:09:25,950
Exactly right.

153
00:09:25,950 --> 00:09:31,080
So you may have forgotten the semicolon, in which case when you go to build and run,

154
00:09:35,430 --> 00:09:37,320
you'll see this red line here.

155
00:09:37,890 --> 00:09:39,330
That's a compiler error.

156
00:09:39,360 --> 00:09:44,250
You'll also see a red arrow over here telling you there's something wrong here and the compiler is telling

157
00:09:44,250 --> 00:09:47,340
you it's expecting a semicolon before the return.

158
00:09:47,520 --> 00:09:48,750
So put it in there.

159
00:09:49,440 --> 00:09:50,370
Just be really careful.

160
00:09:50,370 --> 00:09:55,860
I'll talk about debugging and fixing syntax errors throughout the entire course, but at this point,

161
00:09:56,130 --> 00:09:56,700
save it.

162
00:09:56,700 --> 00:09:57,750
Make sure it's right.

163
00:09:57,750 --> 00:09:58,980
Again, be very careful.

164
00:09:58,980 --> 00:10:01,770
You may have extra quote marks and the compiler won't like it.

165
00:10:01,770 --> 00:10:03,420
You might only have a single.

166
00:10:04,300 --> 00:10:06,220
Less than sign here and it's not going to like it.

167
00:10:06,220 --> 00:10:08,530
So just be sure it's exactly like this.

168
00:10:08,860 --> 00:10:14,320
Once you've got it set up, build, run, build and execute.

169
00:10:15,700 --> 00:10:17,950
There's a clean run and there's my terminal.

170
00:10:20,380 --> 00:10:21,030
So that's it.

171
00:10:21,040 --> 00:10:23,710
We're all set to learn C++.
