Object member allocation

Question

I understand that objects initialized with 'new' are allocated from the heap, but what about their members? For example, I have class A:

class A
{
        private: int a;   //here "a" should be on stack  
};

Then I have object A defined in following code respectively

A a;

A *ap = new A();

Now the first statement places a on stack and ap will be in the heap, but how about a.a and ap->a? Are they with their parent objects?

The instance members of an object are a part of the storage of said object. — obataku, Sep 12 '12 at 03:17

Yes, by definition if an object is on the heap, so are its members, and likewise for the stack.

An object is really just a chunk of memory, so because the object contains the member, thats where the memory for the member will be.

The members are part of the object, just like with a struct.
