I am new to c programming and I was coding some simple programs "Hello world" style.

In all of these programs I put #include<stdio.h> in the top but I am not sure what this means exactly. I googled it and I found that stdio.h is a file that has commands for the preprocessor, but what is a preprocessor? I thought when I write code, I compile it and my code transforms to a form that a "computer" can read and then I can run it. Can somebody explain to me what the usage of this command is?
