declare this as static
declare this as global
define this as equal to the address of the appropriate object
do nothing; it is automatically supplied for you
Answer is Right!
Answer is Wrong!
The correct answer is: D. do nothing; it is automatically supplied for you.
The this
pointer is a special pointer that is automatically supplied to every member function of a class. It points to the object that the member function is called on. For example, if you have a class called Person
with a member function called getName()
, then the this
pointer in getName()
will point to the current Person
object.
You do not need to declare or define the this
pointer. It is automatically supplied to you by the compiler.
The other options are incorrect:
- Option A is incorrect because you cannot declare a member function as static. Static member functions are not associated with any particular object, so they do not have a
this
pointer. - Option B is incorrect because you cannot declare a member function as global. Global functions are not associated with any particular object, so they do not have a
this
pointer. - Option C is incorrect because you do not need to define the
this
pointer. It is automatically supplied to you by the compiler.
