>>What does it mean when you declare something with Void type?
I have only seen pointers of void being declared for example

 C++ Syntax (Toggle Plain Text) 
int a;
char b;
float c;
void *ptr_void;
 
ptr_void=&a;
ptr_void=&b;
ptr_void=&c;
int a;
char b;
float c;
void *ptr_void;

ptr_void=&a;
ptr_void=&b;
ptr_void=&c;

in the above case, void can point to any data type. Maybe some of the more experienced members can help you out with your specific case.

return void; would mean returning nothing. You can simply use return

>>Whats the difference between NULL and 0?
Sorry but I do not know the answer.

What is the astrix mean in this line of code?
The asterisk is used to declare pointers in C++. In your case you have created an array of pointers of type char.
