PART - B (5 x 16 = 80 Marks)
11. Explain in detail the following principles of object oriented programming
(i) Data encapsulation and data hiding
(ii) Inheritance and polymorphism
(iii) Generic programming.

12.a) Create a class complex to represent complex number with overloaded addition and multiplication operators. Use them in a main program.

(OR)

12.b) Define a class string with appropriate constructors, destructor and overloaded +, =, and = = operators use them in a main driver program.

13.a) What are the different forms of inheritance? Give example for them.

(OR)

13.b) Create an abstract base class shape with two members base and height, a member function for initialization and a pure virtual function to compute area ( ). Derive two specific classes Triangle and Rectangle which override the function area ( ). Use these classes in a main function and display the area of a triangle and a rectangle.

14.a) Write a C++ program containing a possible exception. Use a try block to throw it and a catch block to handle it properly.

(OR)

14.b) Create a data class using Java with the following capabilities.
Out the date in multiple format such as
(i) dd - mm - yy
(ii) June 14, 2002.

15.a) Write a Java class point to represent a two dimensional point (x, y). Extend it to a class circle with its centre as the point and an additional radius member and extend further to a class cylinder with additional height member.

(OR)

15.b) Explain the concept of nested classes in Java with a suitable example.
