3. Determining the Size of a Class Object
4. Object
5. sizeof operator
6. Why is the size of an empty class not zero in C++?
7. How do I calculate size of a simple class in C++?
8. Size of a C++ class object
9. Size of a class in C++ | Padding, alignment in class | Size of derived class

Firstly, while in C++ there are member functions, static data members. Do those have any contribution to the size of the class, objects?

The answer is no. Only the non-static data members contribute to the size of class and objects. This is because static members have only one instance which is shared among all objects. And normal member functions are like executable code which does not have size like data members.
