Are you logged in as root? Because it causes problems when logged in as root because the 'root' user isn't told to that the "cs50.h" is a built-in library. You may download the source code of cs50 and put the files "cs50.h" and "cs50.c" to a directory on your workspace .
To include it , type :

#include "yourdir/cs50.h"
//Note: #include <example.h> means built-in header ,  and #include "example.h" means user-written directory.

Question is, how do I know everything of this.
Answer: I'm a Operating System developer . It is a hard project and includes the least used things in the C programming language . E.g. Writing your own standard header files.
