C++ method declaration, class definition problem
- by John Fra.
I have 2 classes: A and B. Some methods of class A need to use class B and the opposite(class B has methods that need to use class A).
So I have:
class A;
class B {
method1(A a) {
}
}
class A {
method1(B b) {
}
void foo() {
}
}
and everything works fine.
But when I try to call foo() of class A from B::method1 like this:
class B {
method1(A a) {
a.foo();
}
}
I get as result compile errors of forward declaration and use of incomplete type.
But why is this happening? (I have declared class A before using it?)
