Are data members allocated in the same memory space as their objects in C++?

Question

Say I\'ve got a class like this:

class Test
{
  int x;
  SomeClass s;
}

And I instantiate it like this:

Test* t = new Test;         


        

Answer 1

class MyClass {
    int i;
    MyInnerClass m;
    MyInnerClass *p = new MyInnerClass();
}

MyClass a;
MyClass *b = new MyClass();

a is on the stack; its members a.i and a.m (including any members of a.m) and a.p (the pointer, not the object it points to) are part of it and so also on the stack.

The object pointed to by a.p is on the heap.

The object pointed to by b is on the heap, including all its members; and so is the object pointed to by b.p.
