I have two class A and B as fllowing
class A {
public:
int i;
public:
A() : i(1) { }
};
class B : public A {
public:
int i;
public:
B() : A(), i(2) { }
};
A has data i, B has a new data i, in fact B has two int numbers. I want to
know how to use the i defined in A with a B object.
Thanks a lot.

Hope all is well! CACF is having a meeting that we hope to have ASAP alumni
representation for around mayoral control in schools and the role of APA
parents and students. Join us to learn about the school system and what you
can do:
Why don’t parents and students have a voice in schools?
Who controls the NYC Public Schools?
· Learn about Mayoral Control and how decisions are made about
education funding and policies that impact schools
· Share your experiences with public schoo
