To try it save the following example on a microSD folder with the name <b>hello.c</b>.

#include "stdio.h"
 
int main(void) {
  printf("Hello world !\n");
  return 0;
}
</pre>

Compile it typing:

<pre class="prettyprint">
~# gcc hello.c -o hello
</pre>

Then lauch it typing:

<pre class="prettyprint">
~# ./hello
Hello world !
</pre>
