Answers:

memory is used by constructor at the time of instaintiation of the class. If we dont instaintiate or create the object of the class, memory is not used by the constructor.
Memory is consumed by the member function at compile time, in terms of block inside a stack.

Depends upon the number of variables used in function definition.
