00:00:05,730 --> 00:00:11,400
In this lecture, we're going to talk about how to set up the infamous Hello World Program.

2
00:00:11,790 --> 00:00:16,890
If you're new to programming, Hello World is just the industry standard.

3
00:00:17,010 --> 00:00:22,770
First program you create to get your feet wet and make sure your environment is running properly.

4
00:00:23,730 --> 00:00:29,070
It's just going to be a super simple program that will output hello world to the console.

5
00:00:30,180 --> 00:00:33,630
All the code that I do throughout this course I will.

6
00:00:34,760 --> 00:00:40,310
Push to get hub and I believe the link to this and the resources tab.

7
00:00:44,070 --> 00:00:48,930
So the first thing that I want to do is show you an extension that I installed.

8
00:00:48,960 --> 00:00:50,760
It is called Rust.

9
00:00:51,090 --> 00:00:52,860
It'll be the first one you type in.

10
00:00:53,250 --> 00:00:55,730
And the extensions marketplace.

11
00:00:55,730 --> 00:01:00,420
Just type in rust and it'll be the first one version.

12
00:01:00,420 --> 00:01:04,770
0.7.8 is what I have installed currently.

13
00:01:07,570 --> 00:01:13,060
So the first thing that we're going to do is type cargo new.

14
00:01:13,750 --> 00:01:14,380
Hello?

15
00:01:16,220 --> 00:01:20,510
And what that did is that created us a new directory called Hello.

16
00:01:21,590 --> 00:01:22,640
So what is cargo?

17
00:01:22,640 --> 00:01:23,840
Cargo is Russ.

18
00:01:24,750 --> 00:01:30,300
Compilation manager, package manager, which is kind of like Pip and Python.

19
00:01:30,450 --> 00:01:33,840
And it is Russ's general purpose tool.

20
00:01:34,320 --> 00:01:41,370
You can use cargo to start a new project, build and run your program, and also manage external libraries

21
00:01:41,370 --> 00:01:43,560
that your code is going to depend on.

22
00:01:44,730 --> 00:01:53,170
Inside this hello folder, you can see that we have a cargo dot tamil folder and all this holds is just

23
00:01:53,170 --> 00:01:56,670
the metadata, which is just a fancier word for information.

24
00:01:58,000 --> 00:01:59,530
For the package.

25
00:01:59,860 --> 00:02:04,150
We will cover cargo a lot more in depth later on in this course.

26
00:02:05,140 --> 00:02:10,680
So now if we look inside of the source folder, we see we have main RS.

27
00:02:11,830 --> 00:02:13,690
Main is the.

28
00:02:14,930 --> 00:02:22,280
File that is going to basically be the centerpiece to creating your binary.

29
00:02:22,490 --> 00:02:28,580
So whatever is inside of main, that's going to be the entry point to running the program.

30
00:02:28,970 --> 00:02:36,530
So what we can do is run is seed into hello and run cargo build.

31
00:02:37,780 --> 00:02:44,460
So now we built the program and it generated a new file for us called Target.

32
00:02:44,470 --> 00:02:50,340
And inside here we have a bunch of different folders that were created, but the main one is Hello Dot

33
00:02:50,410 --> 00:02:53,080
XY, and that's going to be our executable.

34
00:02:53,410 --> 00:03:02,980
So now we can run cargo run and it's going to automatically go in and run the executable for us.

35
00:03:02,980 --> 00:03:07,690
And as you can see, we have outputted hello world to the console.

36
00:03:07,690 --> 00:03:14,500
So congratulations on creating, building and running your first rust program.
