Wasn't the question "how much space get's allocated?" rather than what is sizeof(C)?

The following methods are generated:

class C
    {
        C();
        ~C();
       C(const C & );
       C& operator = (const C &);
       C&  operator *();
       C* operator &();
};

Compiler will create thee methods when they are used. Here, none of these method is used. Are they still created right after "class C{}; "?

The size of empty class is always One . This is because the compiler insert a char, anyhow he need a memory address to identify a class

class C
{
1) A default constructor
C();

2) A default destructor
~C();

3) A copy constructor
C(const C & );

4) A copy assignment operator
C& operator = (const C &);

};



plus

C* operator &();
const C* operator &() const;

I believe this is correct because the code snippet given defines the class C but does not instantiate it. No space is allocated.

Empty class size = 1
There aren't any methods created.

class C{};

C* pc = new C;
int n = sizeof(C);
n = sizeof(*pc);

I don't know why but n was 1.
Still the member methods are created and they are not counted as a size.

that is min the c++ compiler allocates the memory for the class, if it doesn't have any member variables

compiler insert a char for blank class, for it needs a memory address.
member functions aren:t be put in object.

3)A copy assignment operator
4)A destructor
