Accessing attribute of object

[ab123]

Hi I have a scenario like this:

Outer.h--->
Outer{
Foo* f;
Bar* b;
}

Foo{
int a;
float b;
}

Then, In Outer.cxx I want to create object b of Bar such that it can use the member variables of f in the constructor.
Like the constructor for Bar would look something like Bar* b = new Bar(f->a);

Can I do something like this? Can I access the member functions of f when creating b?

Can I do something like this? Can I access the member functions of f when creating b?

Yes

Thanks.
Also, Can I access the member variables of f when creating b?

You can access any member (no matter if variable or function) of an existing object (if this member is accesible, i.e. public)

But you need an object:

Outer o;
Bar* b = new Bar(o.f->a);

You do not need an object if that member is static:

Outer{
static Foo* f;
Bar* b;
};
Bar* b = new Bar(Outer::f->a);

But then I need to ensure that I create object f before I create b right?

for the non static case: yes
