class A {
public:
void f();
protected:
A() {}
A(const A&){}
};
Examine the class declaration shown above. Why are the
default and copy constructors declared as protected?
1. To ensure that A cannot be created via new by a more
derived class
2. To ensure that A cannot be copied
3. To ensure that A cannot be used as a base class except
when public inheritance has been used
4. To ensure that A cannot be created/copied outside the
inheritance chain
5. To ensure that A cannot be instantiated as a static variable

As per interoperatbility programs written in one language
can be used by other language.
How can we restrict the features of one language (say C#)
in the programmer written in another language (say VB)..for
example we have some features like operator overloading
which is possible C#.NET (not in VB.NET), how can we
restrict that when we are using this code in VB.NET.
