Is using pointers faster than using references?

Because a pointer can be NULL. A reference means the object has to exist (of course, that object may not be fully initialized, but it does mean you don't have to worry about a NULL pointer.)

struct A {
	int a;
};
 
void func1(A& r)
{
	printf("r.a = %d\n", r.a);
}
 
void func2(A* p) 
{
	func(*p);
}
...
A* p = 0;
func2(p);

The only reason it blows up is because you are dereferencing a NULL pointer, not because references are not safe.
