I want to forward declare a derived class. I have the following code:

class B: public A;

class A { ... };
class C: public A { ... };
class B: public A { ... };

but this code give me some error. Whats the correct method for forward declaration of a derived class?

Where is `B` referenced that you need it forward declared? – acraig5075 Jan 20 '20 at 06:25
class C used in class B but for summarization I didn't write them. – mahdi Lotfi Jan 20 '20 at 06:28
