# Lecture 4: An overview of C and C++
A long this lecture let us test two basic Hello World scripts on C and C++, respectively. The idea is to remember the compilation chain process to obtain an executable application.

## The Hello-Wolrd on C
The code used for this example is
```c
//Gerardo Marx 24/04/2021
 #include <stdio.h>
 int main(int argc, char *argv[]){
 	printf("Hello World from BeagleBoard!!\n");
 	return 0;
 }
```

then to compile on an executable code use 
```bash
$ gcc hello-world.c -o <output-name>
```
here the `<output-name>` is the name that you want for your executable code.

Now it is possible to execute your new code by using:
```bash
$ ./<output-name> 
$ Hello World from BeagleBoard!!
