1. 7 Marks
   aCompare procedural programming with object oriented programming.
   How to answer

   • Definition of procedural programming and object oriented programming
   • Comparison points: data vs functions, modularity, reusability, security, inheritance
   • Examples of each paradigm
   • Tabular summary of differences
2. 7 Marks
   bExplain features, merits and demerits of Object Oriented paradigm.
   How to answer

   • List features of OOP: encapsulation, inheritance, polymorphism, abstraction
   • Merits: reusability, maintainability, security, extensibility
   • Demerits: complexity, overhead, learning curve
   • Brief conclusion on applicability
3. 7 Marks
   aExplain object model and basic elements of OOPS.
   How to answer

   • Definition of object model
   • Elements: objects, classes, abstraction, encapsulation, hierarchy
   • Relationships: association, aggregation, inheritance
   • Diagram of object model if applicable
4. 7 Marks
   bDiscuss control statements, loops and arrays used in OOPS languages.
   How to answer

   • Control statements: if, if-else, switch
   • Loops: for, while, do-while with syntax and example
   • Arrays: single and multi-dimensional declaration and use
   • Relevance in OOPS languages
5. 7 Marks
   aDefine encapsulation and data abstraction.
   How to answer

   • Definition of encapsulation with data hiding
   • Definition of data abstraction with essential view
   • Difference and relationship between the two
   • Simple example of each
6. 7 Marks
   bWrite a C program to demonstrate the concept of Encapsulation by creating a class Student with data members (roll number, name, and marks) and appropriate member functions.
   How to answer

   • Define class Student with private roll number, name, marks
   • Provide public member functions for input and display
   • Create object and demonstrate data access via methods
   • Show encapsulation via data hiding
7. 7 Marks
   aExplain classes and objects.
   How to answer

   • Definition of class as blueprint/template
   • Definition of object as instance with state and behaviour
   • Relationship between class and object with example
   • Declaration and instantiation syntax
8. 7 Marks
   bDiscuss access modifiers, static members and object life cycle.
   How to answer

   • Access modifiers: private, public, protected with scope
   • Static members: shared data and functions
   • Object life cycle: creation, use, destruction
   • Constructors and destructors role
9. 7 Marks
   aExplain inheritance and its types.
   How to answer

   • Definition of inheritance and reusability concept
   • Types: single, multiple, multilevel, hierarchical, hybrid
   • Syntax/example of each type
   • Advantages and diagram of hierarchy
10. 7 Marks
    bDifferentiate between association and aggregation.
    How to answer

    • Definition of association as general relationship
    • Definition of aggregation as has-a / whole-part
    • Key differences: ownership, lifetime, strength
    • Examples with class diagrams
11. 7 Marks
    aExplain interfaces and abstract classes.
    How to answer

    • Definition of interface and pure abstraction
    • Definition of abstract class with abstract methods
    • Key characteristics and syntax
    • When to use each with example
12. 7 Marks
    bDiscuss their role in software design.
    How to answer

    • Role in achieving abstraction and loose coupling
    • Support for multiple inheritance and extensibility
    • Use in frameworks, design patterns
    • Example design scenario
13. 7 Marks
    aExplain polymorphism with method overloading and overriding.
    How to answer

    • Definition of polymorphism
    • Method overloading: same name different signatures with example
    • Method overriding: redefinition in derived class with example
    • Compile-time vs run-time binding distinction
14. 7 Marks
    bDifferentiate between compile-time and run-time polymorphism.
    How to answer

    • Definition of compile-time (static) polymorphism
    • Definition of run-time (dynamic) polymorphism
    • Comparison on binding time, virtual functions, performance
    • Examples of each
15. 7 Marks
    aExplain exception handling and multithreading.
    How to answer

    • Exception handling: try, catch, throw with example
    • Multithreading: thread creation, synchronization
    • Benefits: robustness and concurrency
    • Simple code snippets
16. 7 Marks
    bDiscuss data collections with a suitable case study (ATM/Library).
    How to answer

    • Overview of data collections: lists, sets, maps
    • ATM/Library case study classes and relationships
    • Use of collections to store accounts/books/transactions
    • Benefits in design and code sketch
