class a
{
virtual void f1()=0;
virtual void f2();
virtual void f3(){};
};
I have no idea about the difference between these three functions(newbie on C++)... Could anyone please explain it for me?

@chris Is f2() the same with f3()? – Sayakiss Jul 25 '13 at 03:47

1`f2` is not defined yet, it needs to be defined somewhere outside the class. `f3` is defined, and it is defined to do nothing. – Benjamin Lindley Jul 25 '13 at 04:26
