WEBVTT 00:00.470 --> 00:02.060 In this lecture I want to go over. 00:02.190 --> 00:11.850 Installing the idea that we're going to use for our C++ programs in IEEE stands for integrated developer 00:11.910 --> 00:13.120 environment. 00:13.650 --> 00:22.880 And what we chose for this course is Eclipse as it will work on basically all operating systems. 00:22.930 --> 00:26.260 But before we do that we need to. 00:26.500 --> 00:32.980 Well first you need to do the steps in the previous lectures for your offerings. 00:33.310 --> 00:45.140 So in previous lectures church just articles outlines the steps that you need to take to install your 00:46.340 --> 00:48.080 compiler. 00:48.130 --> 00:51.830 So if you haven't done that you need to do that first. 00:51.850 --> 01:02.080 So was the video code do that in and come back and we'll start with the ID. 01:02.110 --> 01:14.120 So once you've done that you want to go to coracle dot com and put two downloads in the chevre S E or 01:14.120 --> 01:22.550 follow this link and that will take you to this page and the one we're going to download is the jack 01:22.880 --> 01:25.640 j r e the Java runtime unberth. 01:25.720 --> 01:36.830 Is it that and you'll see the list of all the different versions for the different operating systems. 01:36.830 --> 01:46.150 So the one you probably watch if you're on Windows say is E dot DXi is off line version. 01:46.220 --> 01:51.020 So depends on which or what your computer is. 01:51.050 --> 01:55.380 Either X x or x x x. 01:55.900 --> 02:02.290 So hit accept and then choose the one that pertains to your system. 02:02.380 --> 02:05.260 I'm on a Mac so click. 02:05.470 --> 02:10.360 Mac OS X X X for DNG for Linux. 02:10.360 --> 02:13.550 It really depends on your distribution. 02:14.020 --> 02:15.610 So I've already installed it. 02:16.060 --> 02:23.980 So pause the video and download everything and install everything and then come back and we'll go to 02:23.980 --> 02:24.710 the next step. 02:28.740 --> 02:35.270 So the next step is installing the actual ID itself. 02:35.640 --> 02:46.560 And if you go to a clips or you should see the current version that were you want is called Neon. 02:47.290 --> 02:51.110 And you want to hit other package down. 02:51.210 --> 03:03.300 It's so once you go there what we want is the clips ID for a C and C++ developers so that and on the 03:03.300 --> 03:09.380 right you should see again a list of all the different versions. 03:10.580 --> 03:13.550 Pick the one that suits your system. 03:14.750 --> 03:21.150 So I've already downloaded mine Sue. 03:21.240 --> 03:26.010 Once you have it all downloaded should cease and kind of 03:28.960 --> 03:34.600 file some kind and extract it and you'll see the eclipse. 03:35.440 --> 03:36.580 Application. 03:36.730 --> 04:03.720 So me I need to install it into my application Haitian's folder in it run. 04:03.800 --> 04:11.080 So you should see this prompt which tells you where you want all your programs. 04:11.100 --> 04:14.730 He is your workspace. 04:14.980 --> 04:16.110 I'm launch 04:19.000 --> 04:22.520 this year. 04:22.720 --> 04:24.400 Don't want to see this ever again. 04:25.990 --> 04:37.730 OK. 04:37.820 --> 04:41.660 And you should be taken to this page right here. 04:42.320 --> 04:57.070 And the one we always want is the create a new C++ project at in screen name it's purse agreeing 05:00.250 --> 05:05.820 and the one is always in the executable folder and choose. 05:05.890 --> 05:11.280 Hello world C++ project and toolchain. 05:11.280 --> 05:13.050 This is very important. 05:13.050 --> 05:15.510 This is what you did in the previous lectures. 05:15.510 --> 05:25.920 That's why this appears and the one for Windows would be the men GW GCC for Mac. 05:25.990 --> 05:28.030 Is this one Mac OSX. 05:28.030 --> 05:32.980 Gcc in Linux should just be. 05:33.080 --> 05:44.920 It's probably just gcc in so it's ish. 05:45.330 --> 05:47.020 This is a 05:49.920 --> 06:00.090 so here on the left you have all the files that you have for program so you only have one file right 06:00.090 --> 06:00.660 now. 06:01.550 --> 06:02.930 And in that file. 06:02.930 --> 06:06.150 Here is our actual code. 06:06.210 --> 06:08.500 Finally some code. 06:08.760 --> 06:12.380 So the first two lines. 06:12.570 --> 06:19.650 I'm not going to explain them just yet but just know that you need both of these lines in every program. 06:19.650 --> 06:26.850 We're going to be writing to the next line. 06:26.890 --> 06:36.290 Is the inch main open print secret closed print see the and. 06:36.460 --> 06:42.520 This is actually the entry point into our program. 06:42.540 --> 06:53.420 This is where her program starts every time so we will always need this main function so we don't need 06:53.420 --> 06:55.970 this mean function. 06:56.030 --> 07:08.230 So in this mean function we have this thing called C out and C out really just means cancel out so it'll 07:08.250 --> 07:12.030 print something to our consulate's is our output. 07:12.090 --> 07:14.630 We learned about before. 07:14.780 --> 07:19.520 So this is the tool to use to output things so it's outputting. 07:19.520 --> 07:27.330 This is the kind of output operator in the output operator output. 07:27.350 --> 07:30.340 This string says hello world. 07:31.280 --> 07:38.530 And also put in chain yse the outputs together using its operators as well. 07:38.690 --> 07:46.310 And this will just output a new line in so if we build 07:49.440 --> 07:50.160 project 07:53.540 --> 07:53.950 the 08:00.430 --> 08:05.910 should see the console that it's printed out. 08:06.200 --> 08:07.280 Hello world. 08:07.280 --> 08:08.730 Printed out this. 08:09.030 --> 08:14.070 It's called the string is just a string of characters. 08:16.590 --> 08:26.180 In a new line you so in the last line we have in the main function just returns 0. 08:26.200 --> 08:28.740 Don't go over this more. 08:28.840 --> 08:33.820 So don't really worry about it just know that you have to have this return zero at the end. 08:35.090 --> 08:38.790 So don't worry for not following it just yet. 08:38.810 --> 08:46.100 We'll be doing a lot more examples and writing a lot more programs so you'll start understanding how 08:46.100 --> 08:47.410 this all fits together. 08:47.420 --> 08:54.090 So in the next lecture we'll start really diving deep into what this all means.
