CS 237 - OBJECT ORIENTED PROGRAMMING |
| Time: 3hrs | Max Marks: 100 |
| Answer all Questions |
| PART - A (10 x 2 = 20 Marks) |
| 1. | How are data and functions organised in an object oriented programming? |
| 2. | Compare function overloading and default arguments. |
| 3. | What are the uses of references in functions? |
| 4. | What is dynamic binding? |
| 5. | Compare private and public access specifiers in a class. |
| 6. | Distinguish between overloaded functions and function templates. |
| 7. | What is this pointer? How is it available to member functions of a class? |
| 8. | Can the parameter of a copy constructor be passed by value? Justify your answer. |
| 9. | Compare constructor conversion and operator conversion. |
| 10. | What is the difference between system . out . print and system . out . println in Java? |
| 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. |
