None and all. Well, sort of. Strange eh?

You cannot pass around a void type because it means nothing.

You can assign (almost) any pointer to void*, though it is not usually a good idea to.

void is not part of any class.

void just means "no type".

Suppose:
Expand|Select|Wrap|Line Numbers
  1. void funct(int arg);
  2.  
and you have code:
Expand|Select|Wrap|Line Numbers
  1. int result = funct(25);
  2.  
The compiler now knows funct() returns no type. Therefore, assigning the return from funct() to an integer is not possible so the compiler willl produce an error on this line.
