Agilent Interview Questions !

Few Questions from Agilent Interview :

1]. What are the default member functions included in the class definition ?
2]. Does default destructor provided by the compiler?
3]. How to make a class to restrict its number of instances to 5?
4]. What is singleton class? Design it.
5]. What will happen?

/* Some other code */
}

6]. main(){
int x=5;
printf("%d%d%d",x,++x,x++);
}

7]. main(){

printf("%d%d%d",x,x<<1,x>>1);
}

8]. What are the various storage classes ?
A. Extern, Static, Auto, Register

9]. Is this right ? Why or Why not?
static extern int x;

Ans: No, It will give compilation error. "more than one storage class specified", Reason is obvious.

10]. What is the need of writing our own copy constructor when it is by default provided by the compiler?

11]. What is object slicing?

12]. What is stack unwinding?

13]. Can we use references as class member variables?
Ans: Yes, we can. But then it must be initialized in constructor base/member initializer list. e.g.

class A{
int x;
int &y;
public:
A():x(1),y(x){
cout<<"A x="<
