C# Programming - Classes and Objects - Discussion

2). The term "different data" is ambiguous in this context. Objects of the same class have their own separate instance data but one object could be an identical copy of the other, thus having the same but separate data.

4). The word "conceptually" is key here. Instance fields and methods are implicitly accessed through the this reference even when the this keyword is not specified. For the purpose of C# programming, every object does conceptually have it's own instance members.

5). The CLR is free to optimize memory allocation any way it sees fit. The statement "new int[1000000000]" allocates 1 billion System.Int32 objects. I'm sure there are not 1 billion copies of the code for every method of every instance. You would soon run out of memory.

Missing detailed class definition. 4 & 5 are incompatible: 4 is dedicated for instance classes, 5 for static classes.

Answer should be 2 & 4.

"All objects of Sample class will share one copy of member functions" is extremely wrong. For each object, separate set of methods will be created in the memory.

Statement 2 should also be true. Objects "may" have same or different data. And if option 4 is correct then B. 2, 4 should also be correct.

All objects of Sample class will share one copy of member functions. Seems Wrong.
