By Creating class as a private.
It will not allow that class to inherited.
private class A{
// code
}
class B extends A{ // It will not work.
// Code
}

class ASealedClass;
class MyFinalClass
{
friend ASealedClass;
private:
MyFinalClass(int dummy) {}
};
class ASealedClass : virtual MyFinalClass
{
public:
ASealedClass() : MyFinalClass(0) {} // this is the key .. it
is the virtual inheritance that prevents inheritance
};

Answer / vishaka
The class shoul be made abstract to stop it from being
derived or inherited. To make a class abstract, it should
have atleast one pure virtual function.

What is function overloading?,describe it with the example.
suppose A is a base class and B is the derved class. Both have a method foo which is defined as a virtual method in the base class. You have a pointer of classs B and you typecast it to A. Now when you call pointer->foo, which method gets called? The next part of the question is, how does the compiler know which method to call?
can you give real time example for polymarphism
