C++: Memory Allocation

class A {
    int i;
    class B {
        char c[1024];
    };
};

When we call "A* myA = new A()" the memory looks like this:
- 4 bytes in heap allocated, B was instantiated/allocated

When we call "A myA = A()", the memory looks like this:
- 4 bytes in stack allocated, B was instantiated/allocated

class A {
    int i;
    class B {
        char c[1024];
    } myB;
    // the same as
    // B myB;
};

When we call "A* myA = new A()" the memory looks like this:
- 4 + 1024 bytes in heap allocated, B was instantiated/allocated

When we call "A myA = A()", the memory looks like this:
- 4 + 1024 bytes in stack allocated, B was instantiated/allocated
