actually problem is in class A it is not getting declaration of class B
becoz there u tried to tell one member of class when declaring friend.If
with forwrard declaration when specifying data member of class require its
defination.
class A;
class B//:public A
{
public:
int func(A ob);
};
class B;
class A
{
int a;
public:
int f2(){}
friend int B::func(A ob);
};
class B:public A
{
public:
int func(A ob)
{
}
};
why compilation error is coming over here for friend statement n forward
protype declaration of class B ??
