Which of the following statements are correct about objects of a user-defined class called Sample? All objects of Sample class will always have exactly same data. Objects of Sample class may have same or different data. Whether objects of Sample class will have same or different data depends upon a Project Setting made in Visual Studio.NET. Conceptually, each object of Sample class will have instance data and instance member functions of the Sample class. All objects of Sample class will share one copy of member functions.
Which of the following statements are correct about the C#.NET code snippet given below? sample c; c = new sample(); It will create an object called sample. It will create a nameless object of the type sample. It will create an object of the type sample on the stack. It will create a reference c on the stack and an object of the type sample on the heap. It will create an object of the type sample either on the heap or on the stack depending on the size of the object.
Which of the following will be the correct output for the C#.NET program given below? namespace CuriousTabConsoleApplication { class Sample { int i; Single j; public void SetData(int i, Single j) { this.i = i; this.j = j; } public void Display() { Console.WriteLine(i + " " + j); } } class MyProgram { static void Main(string[ ] args) { Sample s1 = new Sample(); s1.SetData(36, 5.4f); s1.Display(); } } }

All objects created from a class will occupy equal number of bytes in memory. A class can contain Friend functions. A class is a blueprint or a template according to which objects are created.
Which of the following statements are correct about the this reference? this reference can be modified in the instance member function of a class. Static functions of a class never receive the this reference. Instance member functions of a class always receive a this reference. this reference continues to exist even after control returns from an instance member function. While calling an instance member function we are not required to pass the this reference explicitly.
