Explain the passing parameters as function in Call by Value and Call by Reference and then distinguish between them?
Call by value essentially passes a copy of an object's value whereas call by reference essentially passes the object itself. Pass by reference is the preferred method whenever possible as call by value will automatically invoke the object's copy constructor, which is often unnecessary, especially if the object is not affected by the function call (pass by constant reference).
