____39. Reusability is the benefit most often claimed for OOP. However, that is unlikely to be true, as reuse of software is as old as the

____40. We can infer from the passage that…
a)
Object –oriented programming and
b) Object –oriented programming
c) Object–oriented programming and objectobject-based have the same meaning
and object-based are alike
based have dissimilar meaning
Widely-used terminology distinguishes object-oriented programming from object-based. The former is held to include inheritance, while the
latter does not. The exact definitions of these have some variation depending on point of view. In particular, languages with static
typing often have slightly different views of OO than languages with dynamic typing, caused by focus on compile-time vs. run-time
properties of the programs.
____41. According to the extract object-based programming has a…
2
a) Static typing
b) Dynamic typing
c) Flexible typing
The paradigm of OOP is essentially not that of programming but one of design. A system is designed by defining the objects that will exist in
that system, the code which actually does the work is irrelevant to the object, or the people using the object, due to encaps ulation.
The challenge in OOP therefore is of designing a sane object system. It should be noted that there are distinct parallels between the
object-oriented paradigm and Systems theory. OOP focuses on objects as units in a system, whereas systems theory focuses on the
system itself. In between, one may find software design patterns or other techniques that use classes and objects as building blocks
for larger components. Such components can be seen as an intermediate step from the object-oriented paradigm towards the more
"real-life oriented" models of systems theory.
____42. According to the extract OOP is focused to…
a) Programming
b) Design
c) None of the above
According to the object-oriented principles, the verb is attached to the object and logic associated to the requirement is handled in the
object. The following are some examples of the ways by which a subject oriented requirement is translated into object oriented
thinking:

Subject oriented: The Sales Application saves the Transaction



Object oriented: The Transaction saves itself upon receiving a message from the Sales Application
Subject oriented: The Sales Application prints the Receipt
Object oriented: The Receipt prints itself upon receiving a message from the Sales Application
