Question
Which of the following is true?(A) All objects of a class share all data members of class(B) Objects of a class do not share non-static members. Every object has its own copy.(C) Objects of a class do not share codes of non-static methods, they have their own copy(D) None of the abovea.(C) Objects of a class do not share codes of non-static methods, they have their own copyb.(D) None of the abovec.(A) All objects of a class share all data members of classd.(B) Objects of a class do not share non-static members. Every object has its own copy.
Solution 1
The correct answer is (B) Objects of a class do not share non-static members. Every object has its own copy.
In object-oriented programming, each object of a class has its own copy of the non-static data members. This means that if you change the value of a non-static data member in one object, it does not affect the value of that data member in any other object of the same class.
On the other hand, all objects of a class share the static data members and the code of the methods (whether they are static or not). So, options (A) and (C) are not correct.
Option (D) is also not correct because option (B) is true.
Solution 2
The correct answer is (B) Objects of a class do not share non-static members. Every object has its own copy.
Here's why:
(A) is incorrect because not all objects of a class share all data members of the class. Only static data members are shared among all objects of a class.
(C) is incorrect because objects of a class do share the code of non-static methods. They do not each have their own copy of the method code. Instead, all objects of a class access the same method code in memory.
(D) is incorrect because (B) is a true statement.
So, (B) Objects of a class do not share non-static members. Every object has its own copy, is the correct answer. Each object of a class has its own copy of non-static data members. If a change is made to a non-static data member in one object, it does not affect the non-static data members in other objects of the class.
