Question

Match the following with reference to object oriented modelling :

$\begin{array}{clcl}  & \textbf{List-I} && \textbf{List-II} \\ \text{(a)} & \text{Polymorphism} & \text{(i)} & \text{Picking both operator and attributes with} \\ &&& \text{operations appropriate to model an object} \\ \text{(b)} & \text{Inheritance} &\text{(ii)} & \text{Hiding implementation details of} \\ &&& \text{methods from users of objects} \\ \text{(c)} & \text{Encapsulation} & \text{(iii)}& \text{Using similar operations} \\ &&& \text{to do similar things} \\ \text{(d)} & \text{Abstraction} & \text{(iv) }& \text{Create new classes from} \\ &&& \text{existing class} \\ \end{array}$

$\textbf{Codes:}$

• A. $\text{(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)}$
• B. $\text{(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)}$
• C. $\text{(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)}$
• D. $\text{(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)}$

Answer 1

ans will be B

a. Polymorphism---->Using similar operations to do similar things

b. Inheritance   -----> Create new classes from existing class

c.Encapsulation---->Hiding implementation details of methods from users of objects

d.Abstraction--->Picking both operator and attributes with operations appropriate to model an object
