1 00:00:00,910 --> 00:00:02,860 Hello and welcome to a new lesson. 2 00:00:03,130 --> 00:00:08,260 Today, we're going to talk about how to compile your C++ program on a Mac. 3 00:00:08,770 --> 00:00:14,950 So the first thing that you want to do is go up to the search bar type terminal and press the enter 4 00:00:14,950 --> 00:00:15,370 key. 5 00:00:16,030 --> 00:00:22,010 So one thing that you should know is that the terminal is a Unix based terminal. 6 00:00:22,030 --> 00:00:23,530 Very similar to Bash. 7 00:00:24,530 --> 00:00:32,000 So the thing that I want to do is navigate to my desktop folder because this is where I want to create 8 00:00:32,000 --> 00:00:33,740 my C++ program. 9 00:00:34,430 --> 00:00:44,060 But before that, I will create a new directory called Hello World, where I'm going to actually have 10 00:00:44,150 --> 00:00:46,700 my C++ file. 11 00:00:47,360 --> 00:00:53,510 So now I've created that I will navigate to it. 12 00:00:53,810 --> 00:01:02,930 So now I can see I'm inside of my folder and I'm going to type then. 13 00:01:03,890 --> 00:01:09,870 And then the name of my file, which will be Hello, World Dot CBP. 14 00:01:10,490 --> 00:01:15,980 So then is a text editor commonly used for typing code. 15 00:01:16,760 --> 00:01:23,000 And as you can see, it has created and opened my C++ file. 16 00:01:23,970 --> 00:01:24,660 So. 17 00:01:25,690 --> 00:01:32,350 Now that this is open, I can't just start typing code inside of this file. 18 00:01:32,530 --> 00:01:40,720 I actually have to press on I to go into insert mode and this is where you type code. 19 00:01:42,550 --> 00:01:45,850 If you press escape, you go back to command mode. 20 00:01:46,600 --> 00:01:49,330 Command mode is used for navigating. 21 00:01:49,360 --> 00:01:56,050 Also, it protects your file to not be overridden by mistake or you don't want to like type something 22 00:01:56,050 --> 00:01:57,880 and it appears in your file. 23 00:01:58,090 --> 00:01:59,080 So it's nice. 24 00:02:01,060 --> 00:02:02,110 I'm an insert mode. 25 00:02:02,110 --> 00:02:05,320 I'm just going to type up my program real fast. 26 00:02:46,880 --> 00:02:54,170 So now that I have my program all typed up, I will press escape to bring me back to command mode, 27 00:02:54,800 --> 00:03:06,170 and the cool thing about them is that you can use certain keys to navigate around, for example K if 28 00:03:06,170 --> 00:03:07,160 you want to go up. 29 00:03:08,510 --> 00:03:14,450 J, if you want to go down, h if you want to go left and out, if you want to go right. 30 00:03:14,960 --> 00:03:23,780 So now if I go to the end of a line, you can see that I am still basically in between. 31 00:03:23,780 --> 00:03:27,200 If I click on I from Insert and I started typing. 32 00:03:27,740 --> 00:03:32,360 This is basically one character before the end of the line. 33 00:03:32,690 --> 00:03:41,990 So what you want to do is type A and this will bring you to the absolute end of the line. 34 00:03:42,260 --> 00:03:48,290 And now you can create a new line or just maybe type up a comment. 35 00:03:49,550 --> 00:03:51,950 So I just wanted to show you that cool feature. 36 00:03:53,360 --> 00:03:58,700 And now we want to save and exit. 37 00:03:58,700 --> 00:04:02,750 In order to do this, I need to be in this game to be in command mode. 38 00:04:02,750 --> 00:04:08,870 So I press escape and now I'm going to type colon. 39 00:04:10,350 --> 00:04:13,080 Double you from right. 40 00:04:13,350 --> 00:04:16,890 Cue from quit and exclamation mark. 41 00:04:17,520 --> 00:04:21,740 And this is the command that you want to type. 42 00:04:22,050 --> 00:04:26,580 And click Enter to actually save and quit. 43 00:04:27,600 --> 00:04:35,450 The other one that you can do is call an ex that does the exact same thing. 44 00:04:35,520 --> 00:04:38,880 This is actually what I use because I don't want to be typing too much. 45 00:04:39,330 --> 00:04:41,580 But now I click Enter. 46 00:04:42,540 --> 00:04:51,780 And if I type list from list, I can see that inside of my folder, where I am in the terminal, I have 47 00:04:51,810 --> 00:04:55,140 one file Hello World Dot Sweep. 48 00:04:56,250 --> 00:05:01,590 The next thing that I need to do is. 49 00:05:03,740 --> 00:05:12,410 Compile it, so for this, I'm going to type G Plus Plus space and then the name of the file, which 50 00:05:12,410 --> 00:05:20,870 is Hello World Cup and I click Enter now and has been compiled. 51 00:05:22,490 --> 00:05:31,130 And as you can see, Agar out is the executable that was created by the compiler. 52 00:05:32,480 --> 00:05:42,770 So one thing that I do want to mention is if you don't have C++ in for me, this is already installed. 53 00:05:43,070 --> 00:05:52,160 The computer will ask you if you want to install it, so you have the option when you try this to install 54 00:05:52,160 --> 00:05:55,730 it on the spot as it will suggest it to you. 55 00:05:56,000 --> 00:06:00,050 So now the next step that we're going to do is. 56 00:06:02,300 --> 00:06:14,450 Type dog slash aid, not out and click enter, and this is going to run my executable, as you can see. 57 00:06:14,720 --> 00:06:21,200 Hello World appears on my screen because that is what my program is doing. 58 00:06:22,300 --> 00:06:27,520 Now, another cool thing that I want. 59 00:06:28,560 --> 00:06:31,530 To show you is. 60 00:06:34,750 --> 00:06:39,130 This Web site, Vim Hyphen Adventures, dot com. 61 00:06:39,640 --> 00:06:46,750 So this is a game that you can play that actually helps you get better at them and it teaches you some 62 00:06:46,750 --> 00:06:47,830 of the commands. 63 00:06:48,280 --> 00:06:55,270 So I think this is very useful and I would also like to show you, Vinda, or this is where you can 64 00:06:55,270 --> 00:06:58,930 find all the documentation for them if you have. 65 00:07:01,690 --> 00:07:10,210 Any questions or you want to look deeper into what them can do so for us today? 66 00:07:10,240 --> 00:07:11,050 That was it. 67 00:07:11,050 --> 00:07:11,530 So. 68 00:07:12,070 --> 00:07:15,130 Thank you so much for watching and I hope to see you soon.
