About this MCQ
This Medium Object-Oriented Programming (OOP) MCQ checks one syllabus fact.
The question is: “Instance variable is best defined as which of the following?”
The accepted answer is D. A variable defined in a class for which each object of that class maintains its own separate copy.. Instance variable is best defined as which of the following is answered by A variable defined in a class for which each object of that class maintains its own separate copy option D Option A The process by which objects communicate with one another by invoking each other's methods does not match the stem it is a near-miss used to catch incomplete recall of A variable defined in a class for which each object of that class maintains its own separate copy Option B A special method automatically invoked when an object is destroyed used to release resources does not match the stem it is a near-miss used to catch incomplete recall of A variable defined in a class for.
- A. The process by which objects communicate with one another by invoking each other's methods.
Why not A: “The process by which objects communicate with one another by invoking each other's methods.” is not correct. The accepted answer is D. A variable defined in a class for which each object of that class maintains its own separate copy.. Instance variable is best defined as which of the following is answered by A variable defined in a class for which each object of that class maintains its own separate copy option
- B. A special method automatically invoked when an object is destroyed, used to release resources.
