(b) Explain the following concepts of object oriented programming in detail (i). Data abstraction(ii). Inheritance(iii). Polymorphism(iv). Objects
12. (a) (i) Write a C++ program to extract the elements placed in the odd position of the array. (8)
(ii) State the rules to the followed while overloading an operator. Write a program to illustrate overloading. (8)
Or
(b) (i) Discuss about polymorphism and its advantages. (8)
(ii) Write a C++ program that will give the conditions of environment required, food habits and unique characteristics of pet animals fish and dog. Define a base class called pet that describe any common household pet; two derived classes called fish and dog with items specific to that type of animal. Write pure virtual functions in the base class for operations that are common to both types of animals. Write a program to test the usage of classes. (8)
13. (a) (i) Explain the 4 functions Seekg, Seekp, tellg, tellp used for setting pointers during file operation and show how they are derived from fstream class. (4)

Or
(b) (i) Compare the features of C++ versus Java. (6)
(ii) Give an example that fits the following inheritance hierarchy. (10)
Write a Java program to implement this example.
15. (a) Explain about exception handling in Java with suitable examples. (16)
