Difficulty: Hard
About this MCQ
This Hard Object-Oriented Programming (OOP) question asks: In computer science, Composition over inheritance refers to which of the following? The correct choice is A. A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance.. 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. A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance. ✓
- B. A variable defined in a class for which each object of that class maintains its own separate copy.
Why not B: “A variable defined in a class for which each object of that class maintains its own separate copy.” does not fit this question. The answer is A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance..
- C. A mechanism where the method to be executed is determined at compile time based on the object's declared type.
Why not C: “A mechanism where the method to be executed is determined at compile time based on the object's declared type.” does not fit this question. The answer is A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance..
- D. A keyword used in a subclass to refer to members or methods of its immediate parent class.
Why not D: “A keyword used in a subclass to refer to members or methods of its immediate parent class.” does not fit this question. The answer is A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance..
Correct answer
A. A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance.
Explanation
A design guideline suggesting that building complex behavior by combining objects is often preferable to relying solely on class inheritance option A is the accepted answer to In computer science Composition over inheritance refers to which of the following Option B A variable defined in a class for which each object of that class maintains its own separate copy does not fit this question Option C A mechanism where the method to be executed is determined at compile time based on the object's declared type does not fit this question Option D A keyword used in a subclass to refer to members or methods of its immediate parent class does.
