About this MCQ
This Medium Object-Oriented Programming (OOP) question asks: Instance variable is best defined as which of the following? The correct choice is D. A variable defined in a class for which each object of that class maintains its own separate copy.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Object-Oriented Programming (OOP) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Object-Oriented Programming (OOP) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Object-Oriented Programming (OOP) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- 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.” does not fit this question. The answer is A variable defined in a class for which each object of that class maintains its own separate copy..
- B. A special method automatically invoked when an object is destroyed, used to release resources.
Why not B: “A special method automatically invoked when an object is destroyed, used to release resources.” does not fit this question. The answer is A variable defined in a class for which each object of that class maintains its own separate copy..
- C. A mechanism where the method to be executed is determined at runtime rather than at compile time.
Why not C: “A mechanism where the method to be executed is determined at runtime rather than at compile time.” does not fit this question. The answer is A variable defined in a class for which each object of that class maintains its own separate copy..
- D. A variable defined in a class for which each object of that class maintains its own separate copy. ✓
