C++ check list

So, you are making an interview. An well, I'm really upset when you don't know what are the pros and cons for defining a method:

• operator or non operator
• free or class memeber
• virtual or non virtual
• pure virtual or virtual
• static or non static
• const or non-const
• public, protected, private

And about arguments:

• return by value, pointer, const pointer, reference, const reference
• return const or non const
• passing by value, pointer, reference
• passing const or non const

And about costructor, destructor, copy

• private, public, implicit, explicit constructor
• private, public, implicit, explicit copy operator
• virtual , non virtual destructor

Do you know exactly how and when to use all the above?
