What is the difference between these two (pf is a pointer to a
function, and hello is a function):

pf = hello;	

and 

pf = &hello;

The definitions for pf and hello are as follows:

void (*pf)();	// pointer to a function

void hello()
{
  printf("Hello World\n");
}

I used the two different forms of assignments and got the same output.
Is there a difference between them?
