To use the this pointer with a member function, you _____

[amp_mcq option1=”declare this as static” option2=”declare this as global” option3=”define this as equal to the address of the appropriate object” option4=”do nothing; it is automatically supplied for you” correct=”option4″]

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.
